specific Embodiment approach 1

[0008] Specific Embodiment 1: The pesticide used to control rice planthopper in this embodiment mainly consists of 3-15 parts by weight of pymetrozine and 70-80 parts of isoprocarb.

specific Embodiment approach 2

[0009] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that 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 20-70 parts of filler. Others are the same as in the first embodiment.

[0010] The wettable powder and water in this embodiment are mixed in a mass ratio of 1:900-1100.

specific Embodiment approach 3

[0011] Specific embodiment three: the difference between this embodiment and specific embodiment two is that the wetting agent is composed of one of sodium dodecylbenzenesulfonate, saponin, sodium lauryl sulfate and alkyl amido taurate or several compositions; the dispersant is composed of one or more of sodium lignosulfonate, sodium naphthalenesulfonate formaldehyde condensate and sodium dibutylnaphthalenesulfonate; the filler is composed of one of diatomite, kaolin or activated carbon one or more components. Others are the same as in the second embodiment.

[0012] In this embodiment, when the wetting agent is a mixture, various wetting agents may be mixed in any ratio.

[0013] In this embodiment, when the dispersant is a mixture, various dispersants can be mixed in any ratio.

[0014] In this embodiment, when the filler is a mixture, various fillers can be mixed in any ratio.

Abstract

A pesticide which is used for controlling rice planthopper relates to the pesticide. The invention settles the problems of inferior controlling effect, high cost and environment pollution when a routine single insecticide is used for controlling rice planthopper. The pesticide which is compounded by pymetrozine and isoprocarb is mainly composed of pymetrozine and isoprocarb by weight. The pesticide for controlling rice planthopper according to the invention has the advantages of increased control effect, prolonged lasting period, good control effect for the rice planthopper, pesticide amount of about 40g per mu, reduced pesticide dosage, reduced cost and reduced environment pollution. The pesticide according to the invention not only has excellent control effect to the rice planthopper, but also has excellent control effect to aphids or leafhopper, etc.

Description

technical field [0001] The present invention relates to a kind of pesticide. 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 insecticides, such as pymetrozine, imidacloprid, isoprocarb, dichlorvos, and dichloride, 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 for controlling rice planthoppers in order to solve the...
