Abstract

The invention discloses a pesticide composition containing fipronil and picoxystrobin and its preparation and use. The pesticide composition contains active components of fipronil and picoxystrobin and a weight ratio of fipronil to picoxystrobin is in a range of 1: 80 to 80: 1. The pesticide composition can be processed to form a suspending agent, wettable powder, water dispersible granules or an emulsion in water. The pesticide composition containing fipronil and picoxystrobin has good bactericidal and insecticidal effects and can improve a crop yield and reduce a peasant labor cost. The pesticide composition containing fipronil and picoxystrobin can be used for preventing and controlling plant diseases and insect pests of a plurality of crops such as wheat, rice, corn, cotton, vegetables, soybean and fruit trees.

Description

technical field [0001] The invention belongs to the technical field of pesticides and has a synergistic effect of a pesticide composition containing fipronil and picoxystrobin, a preparation and an application thereof. The active ingredients are fipronil and picoxystrobin. Background technique [0002] Fipronil, English common name: Fipronil, molecular formula: C 12 h 4 C l2 f 6 N 4 OS, chemical name: (±)-5-amino-1-(2,6-dichloro-α,α,α,-trifluoro-p-tolyl)-4-trifluoromethylsulfinylpyrazole -3-Nitronitrile, fipronil disrupts central transmission within the central nervous system by blocking gamma-aminobutyric acid (GABA)-mediated chloride transmission. Safe and efficient, no interaction resistance. This product mainly has contact and stomach poisoning effects, has strong systemic activity on rice, and moderate knockdown activity. It has no cross-resistance with existing insecticides, and is effective against resistant or sensitive pests such as organophosphorus, cyclopen...
