一、农业防治实行与非茄科作物3~4年轮作。选用无病壮苗,高畦栽培,合理密植,保护地注意通风。施足腐熟有机肥。盖地膜可减轻前期发病。定植至结果期,及时整枝打杈摘除病叶、病花、病果和下部老叶,带出田外销毁。适时通风降湿,控制浇水。二、生物防治在棉铃虫孵化盛期喷施200单位的苏云金杆菌乳剂100倍液,可兼治粉虱、斑潜蝇等。有条件的,可在棚内释放丽蚜小蜂控制温室白粉虱、烟粉虱等害虫。用植物源农药,如蚜虫宜
First, the implementation of agricultural control and non-Solanaceous crop rotation of 3 to 4 years. Selection of disease-free seedlings, highland cultivation, reasonable close planting, protected places to pay attention to ventilation. Shi enough maturity organic fertilizer. Cover film can reduce the incidence of early. Colonization to the end of the period, timely pruning twig removal diseased leaves, diseased flowers, diseased fruit and the lower part of the old leaves, out of the field destroyed. Timely ventilation and humidity control watering. Second, the biological control In the incubation period of cotton bollworm spraying 200 units of Bacillus thuringiensis emulsion 100 times the liquid, can be both whiteflies, leafminers and so on. Conditional, the release of aphid in the shed wasps control greenhouse whitefly, whiteflies and other pests. Plant-derived pesticides, such as aphids should
