The control effect depends on the resistance of this region. In order to control thrips, common nicotine insecticides such as imidacloprid and acetamiprid can be used. Or spray to control veratrine, Celastrus angulatus, bifenthrin, spinosad, ethyl spinosad, Rhizoctonia solani, spirotetramat, etc. Adding silica gel has better effect. Recommended drugs: ethyl spinosad+chlorfenapyr+silicone penetrant (it can be used when the cost is high and the benefit is good. )。 The effect is good. At the same time, pay attention to the duration of thrips control and the number of days between medicines (or thiacloprid can use this if snails can be found).
Weeds in the field should be removed in time, thrips are easy to hide around the field, and so are the grass in the ridge. Moreover, thrips have the characteristics of lying down during the day and coming out at night, so it is best to take medicine in the afternoon. The drug needs to be absorbed in vivo or added with silicone additives. If conditions permit, it is suggested to combine chemical fumigation with foliar spraying. It is best to spray pesticides on the middle and lower parts of plants and the ground at the same time, because these places are the habitat of thrips nymphs. )
