Method of Use:Fipronil has a wide spectrum of insecticidal activities, including contact killing, stomach poisoning and moderate internal absorption. It can  control not only underground pests, but also ground pests. It can be used not only for stem and leaf treatment and soil treatment, but also for seed treatment. Spraying 25-50g active ingredients per hectare of leaves could effectively control potato leaf beetle, diamondback moth, diamondback moth, Mexican cotton boll weevil and flower thrips. The use of 50-100g active ingredients per hectare in paddy fields can effectively control borers, brown planthoppers and other pests. 6-15g active ingredient/ha foliar spraying can control grasshopper and desert grasshopper pests. 100-150 g active ingredients per hectare applied to soil could effectively control maize root beetles, needles and ground tigers. 250-650g active ingredient/100kg seed treatment of maize seeds can effectively control maize needles and ground tigers. The main control targets of this product include aphids, leafhoppers, Lepidoptera larvae, flies and coleoptera. It is recommended by many pesticide experts as one of the top choices of highly toxic organophosphorus pesticides.
