Embodiment 1

[0019] Example 1 34% pymetrozine. The insecticide wettable powder

[0020] Made by conventional process, 2% pymetrozine, 32% chlorpyramid, 2% sodium lauryl sulfate, 3% sodium lignosulfonate, 2% sodium methylene bis-naphthalene sulfonate, light calcium carbonate supplement to 100%.

[0021] In the present embodiment, the weight ratio of pymetrozine and dichlorpyr can be changed between 1:16-4:1, and the weight percentage of the two can be changed between 1-99%. Also make corresponding adjustment thereupon, form new embodiment.

[0022] It is also possible to replace insectap with cartap, dimehypo, and monosultap to form a new embodiment.

Embodiment 2

[0023] Example 2 72% pymetrozine. Insecticidal single water dispersible granule

[0024] Made by conventional process, including 8% pymetrozine, 64% monosultap, 5% sodium lauryl sulfate, 3% sodium methylene bis-naphthalene sulfonate, 12% sodium lignosulfonate, 5% polyvinylpyrrolidone %, kaolin fills up to 100%.

[0025] In this embodiment, the weight ratio of pymetrozine and monosultap can be changed between 1:16-4:1, and the weight percentage of the two can be changed between 1-99%. Also make corresponding adjustment thereupon, form new embodiment.

[0026] Monosultap can also be replaced by cartap, dimehypo, and dimehypo to form a new embodiment.

Embodiment 3

[0027] Example 3 5% pymetrozine. Insecticide double microemulsion

[0028] Made by conventional technology, pymetrozine 1%, dimehypo 4%, dodecylbenzenesulfonate calcium salt 7%, 1602# phosphate ester 9%, Nongru 700# 4%, N-methylpyrrolidone 5% , 7% isopropanol, 11% toluene, and water to 100%.

[0029] In this embodiment, the weight ratio of pymetrozine and dimehypo can be changed between 1:16-4:1, and the weight percentage of the two can be changed between 1-99%. Also make corresponding adjustment thereupon, form new embodiment.

[0030] It is also possible to replace dimehypo with cartap, monosultap, and dimehytap to form a new embodiment.

Abstract

The invention relates to a pesticide composition containing pymetrozine, and is characterized in that the composition is compounded by one selected from a first active component pymetrozine and a second active component nereistoxin pesticide, and the weight ratio of pymetrozine to nereistoxin pesticide is 1: 60 to 10: 1. The activity of the compounded pesticide composition for treating the pests such as rice planthopper and rice stem borer exceeds the simple accumulation of the activities of the components, and the pesticide composition is capable of solving the problem that the pymetrozine has poor quick action; and the pesticide composition can be applied to the prevention and treatment of insects with sucking mouth parts and lepidopterous pests on crops such as rice, fruit trees, cottons and vegetables, thereby not only reducing the administration quantity per mu (Chinese unit of area), but also being capable of delaying the generation of resistance.

Description

technical field [0001] The invention relates to a pesticide composition, especially an insecticidal composition containing pymetrozine. Background technique [0002] Pymetrozine, English common name pymetrozine, the mechanism of action is that after the adults and nymphs are exposed to the drug, they will produce a stylet blocking effect, stop feeding and cause damage, and starve to death. Long-lasting, it can control most of the Homoptera pests, especially the Aphididae, Whitefly, Leafhopper and Planthopper pests. It is suitable for vegetables, rice, cotton, fruit trees and various field crops. However, in the actual application process, the quick-acting effect of pymetrozine alone is poor, and the pests are prone to develop resistance. [0003] Nereistoxins are a class of biomimetic insecticides. The main varieties of nereistoxins are: cartap, dimehypo, monosultap, chlorxap, sulfonate, Insect ring, polythiane, etc. It has the advantages of being relatively safe to human...
