Suitable for the control of Bemisia tabaci acetamiprid, clothianidin, mineral oil, thiamethoxam (Aketai), nitenpyram, pymetrozine, bifenthrin, abamectin, flavescens Alkali, imidacloprid, chlorpyrifos, etc., can be used to prevent B. tabaci on the persimmon tree.
Long-term single use, Bemisia tabaci easy to produce drug resistance. At present, Bemisia tabaci has been resistant to various common insecticides such as organophosphorus, pyrethroids and carbamates in different degrees. In some areas, Bemisia tabaci has insect growth regulators and nicotinamide insecticides. The resistance is also stronger. In areas where B. tabaci may be resistant to commonly used fungicides, nitenpyram and pymetrozine may be used for control.
In addition, Bayer CropScience's newly introduced 240g/L spirotetramat suspension has a good control effect against Bemisia tabaci and other sucking mouthpart pests, and can effectively prevent and treat the existing insecticides. Sex pests can also serve as an important breed of nicotine insecticide resistance management. It is generally applied during the hatching period of Bemisia tabaci to the younger nymph stage, diluted by 2000-3000 times. The drug has strong systemic absorption and can conduct in both directions in xylem and phloem, but it has poor immediate effect and does not kill adult worms. When there are many adults, it should be mixed with abamectin and chlorpyrifos.
