On April 10th, all village officials in Yushu Village, Dongbu Township, Nanjiang County, concentrated at the vegetable base of the Tianba River and received a vegetable cultivation technique examination by a county agricultural bureau technician. The referents rushed to answer the technology. Staff's "questioning". At 10 o'clock, the exam begins -
"What are the main pests and diseases in common pepper seedlings?"
“Falling disease, blight, gray mold, diseases, and underground pests, etc.†Luo Pengyuan, secretary of the village party branch, replied first.
"Then who is going to talk about what is going on with catastrophic illness, how can we prevent it?"
Director Zhao Mingyong of the village immediately took the words: “The disease is most likely to break out when it is low temperature and high humidity in the greenhouse. The seedlings near the ground are immersed in the base of the stem, shrinking and appearing lines, the cotyledon has not withered yet, and the ground has lost. The ability to support the lodging and death should be used for high efficiency and low toxicity, low residue pesticides, such as: 55% Diocesone 800 times or 50% thiophanate-methyl 1000-1500 times or 70% chlorothalonil WP 800 times , 58% Lei Duomier WP 500 times spray, choose any one of them, every 7-10 days of application of a control, continuous control 2-3 times.
"How do we have control measures for blight?"
"I know this." The village magistrate He Xianfu rushed to say, "The blight is the main disease during the seedling stage. The dead seedlings never fall. We call it 'Standing to Die', and it is easy to raise the temperature in the middle and later stages of high temperature and humidity. Occurs; the control of medicine is the same as that of damping-off."
"Compared to the head." He Shiwei, deputy director of the County Agriculture Bureau and senior agronomist who serves as the "examiner," nodded, "Does the gray mold occur only at the seedling stage? How can it be treated?"
Zou Yinghong, director of the village woman who has grabbed the “answer†right, said that gray mold can occur both at the seedling stage and the adult stage. Sowing seedlings in the seedbed during the seedling period results in long seedlings and weak disease resistance, and it is most likely to occur when the humidity is high. Can be used 50% fast Keling wet powder 1000-3000 times or 25% metalaxyl WP 800-1000 times and other control. Choose any one of them, every 7-10 days of application of pesticide control, continuous control 2-3 times.
"I talked about the disease." Zeng Zhengping, the village supervisor who had the longest dealing with peppers, said eagerly that he would not wait for the examiner to ask, "The disease can be harmed from the seedling stage to the adult stage. There are flooding and brown spots, and the diseased leaves are rotted and rotted, and the leaves and fruits quickly wither and fall off.The pathogenic bacteria are spread by water, and the incidence rate is fast, so in rainy seasons, high humidity fields are prone to happen. The devastating diseases: Pharmaceutical control: 58% Lei Duomier 500-1000 times, 72.2% Precike 600-800 times, 77% WP 600-800 times, 70% Bai Defu WP 500-700 times, 25% metalaxyl WP 800-1000 times, etc. Choose any of them, every 7-10 days of application of a control, continuous control 2 - 3 times."
“You said the disease, then I will talk about insect pests.†Zhang Hao, a university student village official who serves as the assistant to the director of the village of Zhangshu Village, finally said, “The underground pests such as the tigers and earthworms mainly harm the stem near the ground. To kill the whole plant, one can trap and kill: Use Black Light to seduce adult insects or use sweet and sour liquid to seduce adult insects, 6 parts of sugar, 3 parts of vinegar, 1 part of white wine, 1 part of 90% trichlorfon and mix well, or add water with kimchi. Appropriate amounts of pesticides have trapping and killing effects.2) Chemical control: The ground tiger is poorly resistant to 1-3 instar larvae and exposed to host plants or the ground, which is suitable for chemical control. Available 21% synergist cyanine emulsifiable concentrate 8000 Double liquid, 90% trichlorfon 800 times to root control."
After the “examination†was over, He Longping, party secretary of Dongfu Township, who served as “examinerâ€, Zhou Hanguang, the mayor, and He Shiwei, deputy director of the County Agriculture Bureau, showed a satisfied smile, and assured them that the “examinees†had gone deep into the farming household to guide the development of vegetables. .
