After the “summer solstice†entered the summer season, due to the increase in temperature, the propagation of diseases and insect pests of the pepper was accelerated. Failure to prevent and control would lead to the massive death of the prickly ash tree and severe economic losses. The prevention and control methods for the main pests and diseases in Zanthoxylum bungeanum in summer are described below. Please take care of the time.
One, pepper flow gum disease Zanthoxylum bungeanum (dry rot) is a serious branch stem disease often accompanied by Tianniu, Giardinus, in all regions of southern Anhui japonica production areas are affected by the disease, especially in the military There were serious incidents in the cities such as Duwen, Wenxian, Suichang and Kangxian. In general, the incidence rate of the diseased plants in pepper plants is more than 20%, and the highest rate is 100%. The pest index is 30-50. The disease has a high incidence in the high-temperature period and can rapidly cause the necrosis and rot of the phloem at the base of the trunk, which will seriously affect the transportation of nutrients and lead to the yellowing of the leaves and the death of the entire branches or canopies. This often destroys a newly-established pomelo garden.
Control methods: (1) Control pest infestation. The timely prevention and control of insect pests such as Tianniu and Giardia, the protection and enhancement of tree vigor, and the reduction of the occurrence of gum disease have good results. (2) Pharmacy protection. Use a sharp knife to completely scrape off the ulcerous lesions and apply them with a liquid decelerating speed or solibal solution, and then apply a thin layer of mud to absorb the fluid. The effect is excellent.
Second, the root rot of Sichuan pepper root rot of pepper, occurred in the production areas of Zanthoxylum in southern Anhui, the victim rate of more than 85%, the annual mortality rate due to disease reached 15.8%. It has been observed that other diseases of the prickly pear tree can maintain the prickly ash tree for 2 to 3 years before they die. If root rot is felt, the prickly ash tree will die. Therefore, the root rot of pepper is the chief enemy of the Zanthoxylum tree and must not be taken lightly.
Control methods: (1) pay attention to drainage. More rainstorms in summer, in advance by the prickly heat of the tree canopy to build a circle (埂 埂 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , (2) The root cause of the big tree should be cut off in time, and the solibal solution should be painted on the cut-off area, then sprinkled with root rot pesticides and then covered with new soil.
3. Prickly ash rust Prickly ash rust is an important disease in the leaves of Zanthoxylum bungeanum, which can cause a large amount of detachment of the leaves of pepper trees in advance, resulting in the re-emergence of new leaves. This not only affects the nutrient accumulation of pepper trees in the same year, but also important because the secondary leaves consume large amounts of nutrients, directly affecting the yield and quality of the Chinese zanthoxylum bungeanum, and more importantly, it poses a great threat to the life span of the prickly ash tree.
Control methods: (1) Prevention and treatment. Spray Soolitha solution once before onset. (2) timely prevention and treatment. At the height of the onset of the disease, Solipol "99" insecticide net pesticides were sprayed once every 10 days. When spraying, pay attention to spraying pesticides on the leaves, leaves, and trunks. At the same time, it can also prevent and treat diseases and insect pests such as powdery mildew, bituminous coal, aphids, and red spiders. (3) Remove defoliation weeds, concentrate burning and reduce the source of bacteria.
4. There are many types of Tianlong Tianchi in Zanthoxylum bungeanum, and the main hazards of Zanthoxylum bungeanum are the tiger Tianjiu, Xing Tian Niu, Citrus Brownis, and Red-necked Longhorned Cattle, which all occur in the Zanthoxylum-producing areas in southern Anhui. Especially in high-quality and high-yield "Hongpaowang" pepper tree species on the serious damage. Adults bite prickly pepper leaves, lighter damage, larvae bore the trunk, up and down foraging, causing trees to die, resulting in reduced production of prickly ash, heavy damage, every year, 12% of the pepper trees are harmed, the general loss of pepper production of more than 35%.
Control methods: (1) Capture adults. In the summer, the adult worms are manually captured and eliminated at the time of mating on the pepper tree. (2) Elimination of larvae. In the affected area where the tan fluid flows, a small knife was used to pick and kill the larvae. (3) Chemical control. According to the size of the ramp, the wood chips and insects will be cut with a thin wire, and then the syringe will be injected into the tunnel with a syringe. The emulsion will be sealed with mud, and the efficiency will be 100%. (4) The dead trees to be exterminated should be timely excavated and burned, and the insect source should be completely eliminated.
V. Chinese pepper mulberry white peony pepper mulberry white peony, in the southern Anhui provinces zanthoxylum producing areas have occurred, especially in Bailongjiang, Baishuijiang River basin is more common. With nymphs sucking on the trunk of the prickly ash, the number of larvae per square centimeter of the epidermis on the severed branches is often more than 54. Therefore, the injured branches often cause death. For example, thousands of prickly ash trees in Luzi Village, Chengjiao Township, Wudu County did not undergo control, and all of them were killed by Morus alba, resulting in losses of as much as 10,000 yuan.
Control methods: (1) In the first and second generation of nymphs hatching, spraying solibar or methomyl 400 ~ 500 times liquid. (2) In the mature period of nymphs, there is a glial covering that protects the body from sap damage. After smashing with a plastic hard brush, the net spray of Solibal + "99" insecticide was applied, and the effect was 100%. (3) The branches that have died from damage are cut off and burned.
Sixth, pepper and scorpion mosquitoes. There are distributions in the pepper production areas in the south of Anhui Province. The rate of the affected plants is between 1.6% and 100%. After the branches are damaged, the shoots are stimulated to cause tissue hyperplasia and columnar insects are formed. With the increase of worms, dense small nodules emerged in the affected area. Insects can be up to 42 centimeters long, and there are as many as 55 to 335 heads of insects. The affected branches are not only hindered from growing, but are dried up later and often cause tree vigor to die and die.
Control methods: (1) Cut pests, burn them centrally, and disinfect them with Solibal wipes. If they can be pruned continuously for 1 to 2 years, the damage of the pests can be significantly reduced and controlled. (2) After the pepper is harvested, 500-600 times of Dow Chemical is sprayed to kill the adult. (3) The use of cotton vinegar to destroy the original solution of the oxenine on the tumor can produce a good effect.

(2) Pharmacy protection. Use a sharp knife to completely scrape off the ulcerous lesions and apply them with a liquid decelerating speed or solibal solution, and then apply a thin layer of mud to absorb the fluid. The effect is excellent.
