Ultra-low volume combination medicament for controlling rice-stem borer

Abstract

The invention discloses an ultra-low volume liquid for controlling rice-stem borer, which is prepared into an electrostatic spray liquid formulation with the following components: active components, conductive agent, cosolvent and solvent, wherein the active components comprise an active component A and an active component B, the active component A is avermectin, the active component B is one of the following insecticides: triazophos, isocarbophos, profenofos and chlorpyrifos; the components in proportion by weight are as follows: 0.1-5 parts of active component A, 1-60 parts of active ingredient B, 1-3 parts of conductive agent, 2-5 parts of cosolvent and balance of solvent; and the active component A and the active component B account for 0.1%-65% of the total weight of the combination. The weight ratio of effective components of the active component A to the active component B is 0.1:60-60:0.1. The invention has high controlling effect, low dosage, environment protection, convenient processing, low cost, good reagent effect, long persistent effect and high work efficiency, and can reduce environment pollution, improves utilization ratio of pesticides, reduces pesticide consumption and is suitable for electrostatic spraying.

Description

technical field [0001] The present invention relates to abamectin (hereinafter referred to as active ingredient A) and triazophos, isocarbofos, profenofos, chlorpyrifos (hereinafter referred to as active ingredient B) wherein one of them is the effective ingredient for the prevention and treatment of rice scoliosis. The invention discloses an ultra-low-capacity combined medicament for borers and a preparation method thereof, which belong to the field of pesticide preparations. Background technique [0002] Chiloborer belongs to Lepidoptera, Boreridae, is a common pest on rice. Widely distributed in the temperate and subtropical rice regions of Asia, the domestic distribution starts from Heilongjiang in the north, Hainan Province in the south, Taiwan in the east, and Changji and Urumqi in Xinjiang in the west. It mainly occurs in East China and Central China, especially in the Jianghuai rice-wheat double-cropping area, and is the dominant population of rice borer. In additi...
