Honeysuckle, also known as honeysuckle, is also known as "second flower," "double flower," and "double flower." It is a perennial semi-evergreen evergreen shrub with strong adaptability, moisture, drought, and cold resistance. Behind the house, hillside can be planted. Honeysuckle is one of the bulk export medicines in China and domestic demand is increasing year by year. The main pest control methods for honeysuckle are described below for reference.
First, the principle of pest control of honeysuckle According to the "prevention-based, comprehensive prevention and control" of the plant protection policy, based on agricultural control, agronomic measures combined with chemical prevention, scientific use of high efficiency and low toxicity and low residual pesticides, comprehensive use of various prevention and control measures to reduce Losses caused by pests and diseases.
1. Strictly prohibit the use of highly toxic, highly toxic, high residue or triplicate (carcinogenic, teratogenic, mutagenic) pesticides.
2. If it is necessary for production, allow the production base to use a limited amount of organic synthetic chemical pesticides and use them in strict accordance with the prescribed methods.
3. Low-toxicity, high-efficiency, low-residue biopesticides and some moderately toxic pesticides should be selected to promote green machinery.
4. The final residues of organic synthetic pesticides in agricultural products should be strictly controlled and must not exceed the national standards.
5. The number of days between the last application and harvesting shall not be less than the specified number of days.
6. Each organic synthetic pesticide is allowed to be used only once during the growing period of a crop.
7. When using various bio-sourced pesticides with synthetic pesticides in mixed machines, the mixed chemical pesticides are only allowed to use the designated species.
8. Strictly control the use of various genetic engineering microbial preparations.
Second, common pests and honeysuckle control methods Honeysuckle common diseases are brown spot, powdery mildew, anthrax and rust, insect pests are mainly locusts, red spider, longhorn, ulnar and so on.
1, honeysuckle brown spot
1.1 Injury Symptoms: The disease mainly damages the leaves. In the early stage of the disease, yellowish-brown spots appear on the leaves. Several small spots merge together at the later stage and appear rounded or limited by the veins and become polygonal. When wet, there is a gray frost on the back of the leaves. When it is dry, the middle part of the lesion is easily broken. When the disease is serious, the early yellow leaves fall off.
1.2 The characteristics of the disease: The disease caused by the fungus, the disease in the disease leaves overwintering, the second summer of early conidia, conidia spread by wind and rain, usually the first disease from the lower leaves began to gradually develop upward, the bacteria in a high temperature environment Breeding quickly. In general, the onset of disease is heavy from June to August, with severely damaging plants and lots of fallen leaves in the early autumn. According to the investigation of the Plant Protection Station, on April 29, the average rate of brown spot disease strains was 1.0% and the highest was 5.0%; on May 18, the average was 7.7% and the highest was 40.0%; on May 30, the average was 30.0%. 60.0%.
1.3 control methods:
(1) Agricultural measures: Combine pruning in autumn and winter, remove diseased shoots, diseased shoots, clean the ground leaves and burn or bury deep to reduce the source of germs. At the early stage of disease, attention should be paid to the removal of diseased leaves to prevent the spread of disease. Strengthen the cultivation and management, improve plant disease resistance. Apply organic fertilizer on fertilizers, control the application of N fertilizer, apply P and K fertilizers more, promote robust growth of the tree vigor, engage in disease resistance, drain water in a rainy season, reduce soil moisture, trim properly, and improve ventilation and light transmission. Helps control disease occurrence.
(2) Chemical control: At the beginning of the disease, use 70% thiophanate-methyl WP 800 times solution or 70% SON Mn Zn WP 800 times solution or EMPHAINE 1500 ～ 2000 times solution spray, every 7-10 Sprayed once a day, even sprayed 2-3 times, pay attention to alternation rotation application, have better control effect.
2, honeysuckle powdery mildew
2.1 Injury symptoms: mainly damage the leaves, and sometimes also harm stems and flowers. The lesions on the leaves were white dots at the beginning, and later expanded into white powder spots. The entire leaves were covered with white powder layers, yellowing and even defoliation when severe; the upper part of the stems were spotted brown, irregularly shaped, and had white powder; Distorted and severely shedding.
2.2 The characteristics of the disease: The pathogenic bacteria in the ascaria shell on the sick body overwintering, the next year, the ascospores to release ascospore spores for initial infection, after the onset of the disease Department of conidia again reinfection. Warm and dry or shaded between the plants susceptible to disease. Excessive application of nitrogen fertilizer, alternating wet and dry disease. According to the investigation of the Plant Protection Station, on April 28, Zhongling began to appear. On May 18, the average rate of strains of powdery mildew was 8.9%, with a maximum of 40.0%. On May 30, the average was 17.0% and the highest was 20%.
2.3 Control methods: Breeding disease-resistant varieties (when the branches are thick, dense and short, the leaves are thick green, and the quality is thick, densely villous varieties, most of which are strong disease resistance varieties); reasonable dense planting, plastic trimming, improved ventilation Light conditions, can enhance disease resistance; less nitrogen fertilizer, apply more phosphorus and potassium fertilizer; early onset of 15% triadimefon (triadimefon) 1500 times or 50% thiram mildew. Manganese zinc 1000 times or 75% chlorella Clear WP 800-1000 times spray control, once every 7 days, even spray 2 or 3 times.
3, aphids: the insects occur in the upper and middle of April, the fastest breeding at 15-25 °C. The sap of the main plant sucks the leaves, turning the leaves yellow, curled, and shrunken. In severe cases it will cause no harvest. During April-June, the pests were heavy. After the summer, especially on rainy days, the spread was faster. The sap from the larvae and larvae sucked the leaf sap and yellowed the leaves. The honeysuckle flower buds were damaged and the flower buds were malformed; The secretion of honeydew causes the occurrence of soot disease and affects the photosynthesis of the leaves. According to a survey conducted on May 18, the average number of locusts per plant was 22.2% and the highest was 60.0%. The average litchi rate was 55.5% and the highest was 100%. The average amount of pupa was 134.4, and the highest was 555. The locust breeding occurred. Rapidly, the population of insects grows rapidly. If they do not pay attention to prevention and control, they may cause serious reductions in production, and even no harvest.
Control measures: (1) weed removal; (2) Burning or burying dead and rotten leaves can also reduce pests. (3) Before the plant germination, use lime sulfur to spray once, and then spray Qingming, Guyu, and Lixia 1 times each time. This can cure aphids and cure a variety of pests and diseases: (4) Leaves from late March to early April Spread open, when the aphid begins to occur, use 10% imidacloprid wettable powder 1500-2000 times or 3% acetamiprid wettable powder 2000 times or 10% Wanan WP 2000 times spray, 5-7 days 1 Times, even spray several times. The last dose must be taken 10 to 15 days before picking honeysuckle.
4, coffee tiger Tianniu
4.1 Morphological characteristics: adults: body length 9.5 ~ 15 mm, body black, rough head, with granular lines. Antennae are half the length of the body, white hairs at the end of the 6th section, bulbous bulge of the pronotum, 10 yellow-white hair spots on the back, and yellow-white hair spots on each side of the ventral surface. Chestnut brown, with a few white lines formed by dilute white hair, the base of the sheath wing is slightly wider, gradually narrowing towards the end, the surface is finely engraved, and the trailing edge is straight. There are scattered white spots on the mid-posterior chest and abdomen, and there are 1 white spot on each side of the abdomen. In the middle and hindfoot leg segments and the front end of the tarsal segment, most of them are brown-red, and the rest are black. Eggs: oval, about 0.8 mm long, milky white at the time of first birth and later light brown. Larvae: body length 13 ~ 15 mm, young larvae pale yellow, slightly darker after aging.蛹: It is a naked pheasant, about 14 mm long, light brown.
4.2 Infestation symptoms: Overwintering with larvae and adults. The overwintering adults bite through the dry skin of the honeysuckle branch in mid-April of the second year to endanger the hole; overwintering larvae larvae from the end of April to the middle of May, and fall into adulthood in late May. Adult mates spawned under the old skin of coarse branches. After hatching, the larvae begin to feed into the xylem, causing the trunk or main branch to die. After the break, the tunnel was filled with sawdust and insects. In mid-and late-May, spawning takes place in the young stems, and larvae drill the stems to harm the stems, thus killing the whole plant.
4.3 Prevention and control measures: (1) Before the Ming and Qing Dynasties, when Tian Long is about to drill out of the soil, the roots of the plant should be sprayed with dichlorvos; during the spawning period, the 50% phoxim EC should be used to spray and kill. 7-10 days to spray once, even spray several times; (2) When the summer and autumn found in the parasitic branches of Tianni, can cut the young stems about 20 cm, and remove the dry strains, concentrated burned or injection into the wormhole. When stems and leaves were suddenly withered in July-August, dry branches were removed and manually captured;
5, Agaricus fulica: In general, when the head lice are harvested, the harm is serious. The larvae can eat the leaves within a few days. The larvae of the first instar are harmed on the back of leaves, and the lower epidermis and mesophyll tissues are taken, and the upper epidermis is left to make the foliage. It is a white, transparent spot. When it is severe, it can eat up the leaves of the pier. Prevention methods: pruning clean piers in winter, destroying the wintering environment of pests and reducing the source of insects; after the spring, digging the soil within 1 meter around the plants. At the beginning of larvae, it was sprayed with 10% Yong'an WP 2000 times or 10% Wan'an WP 2000 times or 2.5% rattan's fine QI 400-600 times.
6, Starscream: May-June hot and dry climate is favorable for its reproduction, many species, body tiny, red. More concentrated on the back of the plant to draw juice. The damaged leaves were red and yellow at the beginning, and the whole leaves were dry when the latter was severe. The pest is highly fertile and there are many medicinal plants that are harmed by it. In addition to honeysuckle, there are Panax ginseng, Angelica sinensis, habitat, oyster shell, safflower, and Chuanxiong. According to a survey conducted on May 18, the average insect leaf rate of spider mites was 46.5%, and the highest was 100%. The mean average leaf weight was 9.9, and the highest was 42.1. On May 30, there was an average insect leaf rate of 65.0%, the highest 100%, the average amount of leaf average was 25.5, and the highest was 210.
Control methods: cut pests and branches and dead branches, remove deciduous dead branches and burn them; use 30% alum-end EC 1000 times solution or 5% EDA EC 2000 times solution or 5% Nisso EC 2000 times solution or 20% The egg urn net WP 2500 times spray control.
For the prevention and control of anthrax, it can be used 500 to 1000 times perfusion of the enemy's original powder. To prevent and control rust, triadimefon is used. When the chemical is used for prevention and treatment, 50 to 100 grams of detergent can be added to the 50-kg solution as an adhesive.
Third, the prohibition of the use of pesticides on Chinese herbal medicines, medicinal plant pest control must ensure safety and prevent pesticide residues. Most of the Chinese herbal medicines are taken orally, and the use of highly toxic pesticides that are highly toxic is strictly prohibited so as not to affect the health of the patients. Honeysuckle flower buds must not use toxic pesticides to prevent poisoning and honeysuckle from losing value. According to Announcement No. 199 of the Ministry of Agriculture of the People's Republic of China, pesticides that must not be used or restricted on Chinese herbal medicines, fruit trees, vegetables, and tea are: methamidophos, methyl parathion, parathion, monocrotophos, and phosphine amines. , Phosphor, methylisotriphos, tert-butyl, methylthiophosphor, phosphorus, phosphorus, carbofuran, aldicarb, pyrophosphate, thiophos-phorus, chlorprophos Fifteen kinds of highly toxic pesticides such as fly phos- phorus, chlorazole, and phenyl-phosphorus.
Fourth, scientific and reasonable chemical control The advantages of chemical control is quick, effective, easy to use, can eliminate or control a large number of pests and diseases in a short period of time, subject to regional or seasonal restrictions are relatively small. However, there are also shortcomings in chemical control, such as long-term use, pests are easy to produce drug resistance; while killing days, some pesticides are more toxic, there are residual drugs, can pollute the environment, affecting human and animal health.
1. Symptomatic medication, clear control of the object. When selecting a pesticide, it is necessary to clarify the physiological mechanism and hazard characteristics of the control object, as well as the variety and growth period of the crop.
2. Do a good job of investigation of pests and diseases and seize the drugs in the key period. Before the application of pesticides, we must seriously carry out pest investigations, grasp the control period, and apply pesticides during the best period of prevention and treatment. Otherwise, the application is too early and the efficacy is not consistent with the period of pest control, which does not control the hazard. The late application of the pesticide is not effective, and it will not only cause no control, but also cause waste of pesticides. General insecticides should be held in the hatching to the larvae before the 3rd instar, pests rolling leaf feeding and pest control, should be mastered before the roll leaf feeding for the best effect.
3, can not arbitrarily increase the dosage or increase the concentration of medication. Many farmers mistakenly believe that increasing the amount of medication or increasing the concentration of medication will increase the effectiveness. Therefore, the phenomenon of arbitrarily increasing the dosage of drugs without following the instructions is prevalent. In addition, farmers do not use prescriptions when dispensing medicines. They only use bottle caps and other measures. The lack of a quantity concept results in excessive use of drugs, which not only results in waste, but also easily causes phytotoxicity, pollutes the environment, and endangers the health of people and livestock.
4, can not be a single long-term use of a pesticide, as well as increasing drug resistance year by year. In the use of pesticides, if a pesticide is found to be effective, it will be used continuously for a long period of time. Even if the effectiveness is reduced, it will not be replaced. It is believed that the decrease in the control effect is a low pesticide content. It is not recognized that this is caused by a single use of a pesticide for a long period of time. as a result of. The data show that the use of quick-drying in controlling gray mold in the 1980s was very effective. The resistance in the mid-1990s increased to 680-fold. In 1978, the spider mite was used to prevent and control 6000 times of red spider, and the control efficiency was over 98%. Now it uses 1000. Less than 50% control effect. There are more than 30 kinds of pests and more than 10 kinds of germs in the country have produced different degrees of resistance to dozens of pesticides.
5, mixed use of pesticides, pay attention to a reasonable match. The alternative use of pesticides with different mechanisms of action or the rational use of pesticides based on the physicochemical properties of pesticides can not only improve control efficiency, but also delay the occurrence of pest resistance.
6, pay attention to weather changes, choose the weather application. Select the appropriate application time, we must consider the effectiveness of control, but also conducive to safe drug application. Spray pesticides should be selected when there is no wind or breeze on sunny days. General pesticide spraying temperature is 20-30 °C. Excessive air temperature is not only volatile, decomposing, affecting control, but also causing poisoning. When a herb is applied on a windy day, the pesticides tend to drift with the wind, making it difficult to reach the target site. Not only will they not receive the desired results, but they will also seriously pollute the environment. In cloudy and rainy days, pesticides will be easily lost, and it will be difficult to receive the expected results. Cause environmental pollution. In general, in the spring and autumn, the temperature at noon is mostly 15-30°C, and the application effect is good at 11-15 hours. During the high temperature summer season, the temperature is above 30°C at noon, and the application is better at 8-11 am or 15-18 pm.
7. Pay attention to the safety interval of pesticides. Dosing is prohibited during safety intervals.
8, clear and efficient and highly toxic concept. Many farmers mistakenly believe that as long as the toxicity of pesticides is large, the efficacy is good, and it is not clear that high efficiency and high toxicity are completely different. For high-efficiency, low-toxicity, low-residue pesticides, it is considered that the toxicity is low and the effect is not good. They are reluctant to use it.
9. Use well-functioning equipment to master the correct method of application. Promote the use of Guardian brand high-efficiency nebulizers and motorized sprayers, and eliminate outdated workers and peasants--16 sprayers. When spraying, pay attention to spray evenly, spray thoroughly inside and outside, up and down, left and right.
10, pay attention to operating procedures. Do not eat, drink, smoke, and wash your hands before meals. During the operation process, always apply in the upwind position. The machine will be blocked. Do not blow the nozzle with your mouth. In addition, frail, malnourished people are more prone to poisoning, and these people are not suitable for pesticide application.
First, the principle of pest control of honeysuckle According to the "prevention-based, comprehensive prevention and control" of the plant protection policy, based on agricultural control, agronomic measures combined with chemical prevention, scientific use of high efficiency and low toxicity and low residual pesticides, comprehensive use of various prevention and control measures to reduce Losses caused by pests and diseases.
1. Strictly prohibit the use of highly toxic, highly toxic, high residue or triplicate (carcinogenic, teratogenic, mutagenic) pesticides.
2. If it is necessary for production, allow the production base to use a limited amount of organic synthetic chemical pesticides and use them in strict accordance with the prescribed methods.
3. Low-toxicity, high-efficiency, low-residue biopesticides and some moderately toxic pesticides should be selected to promote green machinery.
4. The final residues of organic synthetic pesticides in agricultural products should be strictly controlled and must not exceed the national standards.
5. The number of days between the last application and harvesting shall not be less than the specified number of days.
6. Each organic synthetic pesticide is allowed to be used only once during the growing period of a crop.
7. When using various bio-sourced pesticides with synthetic pesticides in mixed machines, the mixed chemical pesticides are only allowed to use the designated species.
8. Strictly control the use of various genetic engineering microbial preparations.

The lack of a quantity concept results in excessive use of drugs, which not only results in waste, but also easily causes phytotoxicity, pollutes the environment, and endangers the health of people and livestock.
4, can not be a single long-term use of a pesticide, as well as increasing drug resistance year by year. In the use of pesticides, if a pesticide is found to be effective, it will be used continuously for a long period of time. Even if the effectiveness is reduced, it will not be replaced. It is believed that the decrease in the control effect is a low pesticide content. It is not recognized that this is caused by a single use of a pesticide for a long period of time. as a result of. The data show that the use of quick-drying in controlling gray mold in the 1980s was very effective. The resistance in the mid-1990s increased to 680-fold. In 1978, the spider mite was used to prevent and control 6000 times of red spider, and the control efficiency was over 98%. Now it uses 1000. Less than 50% control effect. There are more than 30 kinds of pests and more than 10 kinds of germs in the country have produced different degrees of resistance to dozens of pesticides.
5, mixed use of pesticides, pay attention to a reasonable match. The alternative use of pesticides with different mechanisms of action or the rational use of pesticides based on the physicochemical properties of pesticides can not only improve control efficiency, but also delay the occurrence of pest resistance.
6, pay attention to weather changes, choose the weather application. Select the appropriate application time, we must consider the effectiveness of control, but also conducive to safe drug application. Spray pesticides should be selected when there is no wind or breeze on sunny days. General pesticide spraying temperature is 20-30 °C. Excessive air temperature is not only volatile, decomposing, affecting control, but also causing poisoning. When a herb is applied on a windy day, the pesticides tend to drift with the wind, making it difficult to reach the target site. Not only will they not receive the desired results, but they will also seriously pollute the environment. In cloudy and rainy days, pesticides will be easily lost, and it will be difficult to receive the expected results. Cause environmental pollution. In general, in the spring and autumn, the temperature at noon is mostly 15-30°C, and the application effect is good at 11-15 hours. During the high temperature summer season, the temperature is above 30°C at noon, and the application is better at 8-11 am or 15-18 pm.
7. Pay attention to the safety interval of pesticides. Dosing is prohibited during safety intervals.
8, clear and efficient and highly toxic concept. Many farmers mistakenly believe that as long as the toxicity of pesticides is large, the efficacy is good, and it is not clear that high efficiency and high toxicity are completely different. For high-efficiency, low-toxicity, low-residue pesticides, it is considered that the toxicity is low and the effect is not good. They are reluctant to use it.
9. Use well-functioning equipment to master the correct method of application. Promote the use of Guardian brand high-efficiency nebulizers and motorized sprayers, and eliminate outdated workers and peasants--16 sprayers. When spraying, pay attention to spray evenly, spray thoroughly inside and outside, up and down, left and right.
10, pay attention to operating procedures. Do not eat, drink, smoke, and wash your hands before meals. During the operation process, always apply in the upwind position. The machine will be blocked. Do not blow the nozzle with your mouth. In addition, frail, malnourished people are more prone to poisoning, and these people are not suitable for pesticide application.
