Embodiment 1

[0007] Embodiment 1: In this embodiment, the pesticide for controlling rice planthopper is a wettable powder, and the wettable powder also includes 10 to 40 parts of wetting agent, 10 to 40 parts of dispersant and 20 to 70 parts of filler. The wettable powder and water in this embodiment are mixed in a mass ratio of 1:900-1100.

Embodiment 2

[0008] Embodiment 2: The difference between this embodiment and specific embodiment 1 is that the wetting agent is composed of one or Several compositions; the dispersant is composed of one or more of sodium lignosulfonate, sodium naphthalenesulfonate formaldehyde condensate and sodium dibutylnaphthalenesulfonate; the filler is one of diatomite, kaolin or activated carbon or several components. Others are the same as in Embodiment 1.

Abstract

The invention relates to a rice hopper control pesticide. The pesticide is mainly composed of isoprocarb. Only about 40g of the pesticide is applied to per 666.7m<2> of field, so the reduction of the dosage reduces the cost and reduces pollution to environment.

Description

technical field [0001] The invention relates to a pesticide, in particular to a pesticide for controlling rice planthopper. Background technique [0002] Rice planthopper is the most important pest on rice. Its occurrence and damage are hidden, explosive and destructive, and it is very harmful to rice yield. Conventional single insecticide pesticides such as pymetrozine, imidacloprid, isoprocarb, dichlorvos, and dichlorfone are the counterpart pesticides for the control of rice planthoppers. Due to the long-term use of single insecticides and unreasonable application techniques, the use of These existing single insecticides have poor control effects on rice planthoppers, and in order to effectively solve the problem of insect pests, the method of increasing the dosage is usually adopted, but this not only increases the cost of planting crops, but also pollutes the environment. Contents of the invention [0003] The object of the present invention is to provide a pesticide...
