New technology for preventing and controlling pollution-free vegetable pests and diseases

High Temperature Sterilization: The day before the high temperature sterilization to control cucumber downy mildew, the cucumber was poured with water once, the greenhouse was closed the next day, a thermometer was placed inside the greenhouse, and the temperature was raised by noon sunlight to rise to 44-45 in a short period of time. °C, keep for 2 hours, then slowly release the air, reduce the temperature to normal temperature, which is conducive to the normal growth and development of cucumber.

Bio-pesticides: Bio-pesticides include bt bio-insecticides, cabbage worm granules virus preparations, and beneficial micro-organisms to increase production of bacteria. 150-200 ml bt bio-insecticide per acre, sprayed once a day for 7 days, can effectively kill the 1~2 instar larvae of cabbage caterpillar, diamondback moth, bean maggot; use Liuyangmycin, avermectin 2500-3000 times liquid, control red spider, aphids, spotted fly; with agricultural streptomycin, neophytin 4000 ~ 5000 times, to prevent bacterial diseases of vegetables.

The natural enemy pest control: the use of cicaderum wasp to control whitefly, the use of Trichogramma beetle control cabbage caterpillar, corn borer, cotton bollworm, the use of seven-spot ladybugs, grasshoppers control aphids, mites, the use of frogs to prevent butterflies, moth pests.

Yellow plate trapping: According to the characteristics of aphid and whitefly having a strong tendency towards yellow color, yellow plate oil is used in greenhouses to prevent and control aphids and whitefly.

High-tech: The use of detoxification techniques for garlic, strawberries, and potatoes can effectively reduce the incidence of viral diseases and increase yields; the use of grafting techniques for melons to increase the yield, such as the grafting of watermelons, eggplants, cucumbers, and tomatoes, can be effective Control the occurrence of soil pests and diseases, and increase the yield and quality of vegetables.

Plant pest control: The use of garlic, onion, loofah leaves, tomato leaf leaching solution made of pesticides, can control aphids, spider mites, the use of Sophora flavescens, Skunk, onion leaves leachate, control aphids, cabbage caterpillars, cabbage aphids.

Manual killing: The use of insect dead, phototaxis, using black light to kill. The underground pests gather under the leaves of sycamore and can trap and kill sycamore leaves.
