Bulbophyllum is a fungal microbial insecticide, mainly through the large number of pests in the body to achieve the purpose of killing pests, currently known can infect 6 orders 15 families of more than 200 kinds of pests and mites, because the agent can be used all year round, while not harming natural enemies and due to biological, non-toxic and non-polluting, fully in line with the purpose of pest management, easy to produce, low cost, therefore, has broad application prospects.
Principle of insecticidality
Coccidioides are a kind of fungus of the subphylum hemiknosporus, after contact with pests, under suitable environmental conditions, conidia can germinate and grow bud tubes on the epidermis of pests, and produce lipase, proteases, chitinase and other substances to dissolve the epidermis of insects, enter the body through stomata, multiply in large quantities in the insect body, consume nutrients in the body, form a large number of hyphae and spores, and grow all over the body of the insect. At the same time, various toxins are produced in the body of the pest, affecting blood circulation, interfering with metabolism, except for some body walls, other tissues are destroyed, and nutrients are also exhausted. The pest dies after 2 to 3 days. The carcasses turn white and stiff, and the surface of the body is covered with white spores, which can spread with the wind or come into contact with other insect bodies, continuing to infect other pest individuals.
Main features
Coccidioides albicans mainly through parasitic pests to achieve the purpose of killing pests, because of its wide parasitic range, strong reproductive ability, therefore, coccidioides albicans have a wide range of pest control, continuous insecticidal ability, pests will not produce resistance, non-toxic and non-polluting, easy to produce, low price and other characteristics, is widely used in the control of forest pests, underground pests, crops and vegetable pests.
Prevention and control objects
It is mainly used for the control of tea small green leafhopper, American white moth, broad-shouldered star tianniu, beet night moth, aphid, tobacco whitefly, white mealybug, twill nocturnal moth, pine bald roundworm, Xiao's pine stem elephant, Yang Xiaozhou moth, bamboo locust, pine caterpillar, corn borer, sorghum borer, soybean heartworm, weevil, potato beet, tea small green leafhopper, rice bud, rice leafhopper, rice planthopper, slug, grub, golden needle worm, ground tiger, root maggot, leek and other lepidoptera, hymenoptera, homophaloptera, orthoptera pests.
Scope of application
Mainly used in wheat, corn, cotton, soybeans, peanuts, tomatoes, peppers, eggplant, cabbage, kale, cauliflower, leeks, green onions, garlic, sesame seeds, apples, pears, cherries, bananas, grapes, mangoes, pines, poplars, bamboo, tea trees and so on.
How to use
Coccidioides can be used for seed mixing, soil treatment, spreading, powder spraying, spraying and other methods
Use technology
(1) Control of green onions, garlic, leeks and other underground root maggots, leeks, etc., in the root maggots young larval bloom period of administration, can be used 15 billion spores / gram coccidioides white zombie granules 250 ~ 300 grams and fine soil mixed well and then sprinkled along the ridge, and then watered, can effectively prevent the harm of leeks.
(2) Pine, poplar, bamboo and other control of pine caterpillars, American white moth, broad-shouldered star bull, twill moth, pine bald roundworm, Xiao's pine stem elephant, Yang Xiaozhou moth, bamboo locust, etc., in the pest young larval stage of the drug, can be used 40 billion spores / gram coccidioides can disperse oil suspension 2000 ~ 2500 times liquid spray, sprayed once every 10 days, sprayed 2 to 3 times, can control the harm and spread of the above pests for a long time.
(3) Control of peanuts, sweet potatoes, potatoes and other crops of grubs, grubs, golden needle worms and other underground pests, with 15 billion spores / gram coccidioides wettable powder 250 ~ 300 grams with fine soil or fine sand 15-20 kg mixed well, in the peanut sowing period or peanut flowering under the needle stage applied to the peanut mound around. Then watering can effectively control the damage of underground pests.
(4) Control of wheat, corn, peanuts, soybeans and other crops of aphids, beet moths, twill moths and other pests, with 15 billion spores / gram coccidioides albicanizable wettable powder 15-20 g / mu, mixed with water 30 ~ 40 kg evenly sprayed.
Special reminder
The temperature of Coccidioides is well developed under the conditions of 24 °C ~ 28 °C and relative humidity of more than 80%, so try to choose to use it after rain or after watering when the humidity in the field is large.
