Recently, some greenhouse vegetables (eg eggplants, cucumbers, etc.) are seriously endangered by small pests such as whitefly, aphid, and spotted fly. Small pests have the characteristics of strong reproductive ability, rapid propagation, and easy occurrence of other diseases, and because of their large number of populations and strong concealment, they cause great difficulties in the thorough removal of work. When the pests occur seriously, it will cause wilting and death of the whole plant, which will seriously affect the yield and quality of vegetables. To prevent and control small pests in greenhouse vegetables, comprehensive measures should be taken. The first is to use anti-virus resistant varieties and do seed disinfection. The second is to plant in due course. The high temperature and dry environment in autumn creates favorable conditions for the occurrence of whiteflies and roundworms. After timely delay of planting dates and avoiding the high incidence of small pests, the loss of vegetable crops can be reduced. The third is to implement green prevention and control technology. After harvesting the spring flooded crops, the crop residues should be promptly removed, and the land should be deep-turned. Insect repellent nets should be placed in summer after high-temperature stuffy sheds or medicinal smoked sheds, to prevent insects outside the shed from entering the shed, and to suspend the swatches to monitor pests after planting. Dynamic. Fourth, chemical control. When serious pests occur, chemical agents may be used for prevention and control. The control of Bemisia tabaci can use 19% of cyanopteranidamide suspension, 99% of mineral oil EC, 22.4% of spirotetramat suspension, etc.; control of aphids can use 1.5% of matrine solution, 10% of cyantranilamide Dispersible oil suspending agents, etc.; can be used to prevent yellow spotted fly can use 10% of cyanopteranidiamide can be dispersed oil suspension, 4.5% beta cypermethrin EC, 30% ciprofloxacin WP, 1.8% avermectin EC.
