Rotational Drug Control Against Soybean Beet Armyworm
Emamectin benzoate, cypermethrin, and chlorpyrifos are suitable drugs for controlling Spodoptera exigua. From the application situation in recent years, Spodoptera exigua has strong resistance to common pyrethroid pesticides and organophosphorus pesticides. In some regions, Spodoptera exigua has strong resistance to emamectin benzoate. For the control of Spodoptera exigua, the appropriate period of application is the hatching of the egg to the larval 1 to 2 years of age. Indoxacarb, cyanocaprozin, chlorantraniliprole, lufenuron, chlorfenapyr, spinosad, spinetoram, and other drugs can be used to bind these drugs with methyl avermectin Alternate use of acid salts, pyrethroids, etc., can help delay pest resistance. It is best to apply in the evening, because the newly hatched larvae are concentrated in the heart or the back of the leaves, it is important to spray these areas, the spray should be uniform. Plants are also sprayed on the rhizosphere to prevent larvae that fall to the ground.
