Perfect Killer is one of the insecticides used to kill termites and other insects. It is a synthetic used as an on a large scale. Cypermethrin is highly effective in killing, according to the National Pesticides Telecommunications Network. It is found in many household ants and cockroach killers, including Raid and ant chalk. Cypermethrin 10% (EC) when sprayed at the concentration of 100 g ai ha−1 showed a residue level of 0.71 mg kg−1 at 0 day followed by 0.52 mg kg−1 at 1 day in dry season, which were higher than the recommended of 0.5 mg kg−1 set for grains, beans with pods such as Rice, Millet, Sorghum, Soya beans cocoa, Kolanut,Guava and so on . It is very effective for spraying plants and other crops without causing any damage to them. The average residue level of any depends primarily on the quantity of its active ingredient. A pre harvest interval of 3 days might be considered for dry season. But in case of early wet season where crop canopy was smaller allowing higher deposition of cypermethrin residues on pods, it showed a preharvest interval of 10 days for the safe use. So vegetable soybean should be harvested after 10 days of cypermethrin application.v.
