Sorghum aphids can be controlled by referring to the following methods:
Use 0.1 kg of 40% dimethoate emulsifiable concentrate per mu, mix with 10 kg of fine sand, and broadcast it onto the plant leaves; or spray with 50% pirimicarb wettable powder at 800 times dilution. Or use 40% omethoate combined with 10% imidacloprid for a joint application, which has a significant effect (note: avoid applying the pesticide in high-temperature weather to prevent poisoning incidents; applying it before 10 a.m. or after 5 p.m. is safer).
