In the autumn of August, tomatoes will be planted in greenhouses in the future. Hopefully, growers will not be able to relax and control the tomato yellow leaf curl virus disease in the autumn greenhouse. 1. Prevention cannot be relaxed. The tomato planting period in the greenhouse in the fall coincides with the high incidence period of Bemisia tabaci and tomato yellow leaf curl virus disease. Bemisia tabaci breeding and high efficiency of virus transmission, when the climatic conditions are suitable, it will facilitate the rapid increase of insect population and diffusion of virus, a small amount of insect population can be Causes a large area of ​​transmission. 2. Press the link to check. Clear the suspected diseased seedlings before planting, use the insecticide to spray the seedlings to ensure the planting of insect-free and disease-free seedlings; lay the insecticide-proof net in the greenhouse, block the whiteflies, use the dichlorvos smoke agent to seal the smoke, or use spicy The root element is subjected to air-tight, smoke-tight application. It can also be used for 3 to 5 days at high temperatures to block the situation according to the weather conditions, kill the whitefly, ensure the colonization in an insect-free environment, suspend the yellow plate as early as possible after planting, and strengthen investigations to remove diseased plants in time. With proper handling, it was found that when the Bemisia tabaci has risen, the emergency treatment of pesticides has been promptly adopted. 3. The application of measures must be in place. The number of insect nets should be appropriate, coverage should be all-round; the time for yellow panels to hang early, on the one hand to monitor the insect situation, on the other hand to control the density of insect population; coordination of insect nets, yellow plates and pharmaceuticals, can be carried out once after the hood net Pharmacy control, kill the tobacco whitefly stung in the greenhouse, and then, based on the monitoring results of the pest situation, implement chemical control when necessary. It is not appropriate to hang the yellow plate when the population density is high. At this time, the insecticide should be sprayed to kill most of the insect sources, and then the yellow plate should be used to eliminate the remaining insect population. Pharmaceutical Intermediates
