1.Fipronil, chemically known as 5-amino-1-(2, 6 dichloro-4-trifluorotolyl)-4-trifluoromethyl-sulfinyl-pyrazole-3-carbonitrile, is the first benzopyrazole used for pest control. since its discovery in 1987, it has been widely used in many fields such as agriculture and veterinary medicine, becoming a heavy Chemicalbook insecticide species. Fipronil, the trade name of Rexinte, is a new type of benzopyrazole insecticide, which has the advantages of broad spectrum and high efficiency compared with traditional insecticides (organophosphates, pyrethroids, carbamates), and has been widely used in many agricultural fields, and is a common insecticide used for pest control.
2.Fipronil mainly induces Cl-flow by blocking the neural membrane Cl-channel controlled by γ-aminobutyric acid receptors, which causes extreme excitation of the nervous system and leads to insect mortality, and achieves the effect of prevention and control of various economic pests.

1.Fluoropyrazole containing broad-spectrum insecticide, high activity, wide range of applications, to Hemiptera, Compositae, Coleoptera, Lepidoptera and other pests and pyrethroids, carbamate insecticides have developed resistance to pests also show very high sensitivity. It can be used in rice, cotton, vegetable, soybean, rape, tobacco, potato, tea, sorghum, corn, fruit tree, forest, public health, animal husbandry, etc. Chemicalbook controls rice stem borer, brown fly, rice weevil, cotton bollworm, stick insect, small vegetable moth, cabbage moth, kale night moth, beetle, root cutter, bulb nematode, caterpillar, fruit tree mosquito, wheat long tube aphid, coccid, trichoderma, etc. The recommended dosage is 12.5~150g/hm2. China has approved the field efficacy test on rice and vegetables. Formulation is 5% gel suspension and 0.3% granule
2.It is mainly used on crops such as rice, sugar cane, potatoes, etc. In animal health care, it is mainly used to kill parasites such as fleas and ticks on cats and dogs.
