Embodiment 1

[0013] 40% chlorpyrifos · chlorpyrifos, namely the emulsifiable concentrate whose mass ratio is 1:19

[0014] Chlorpyrifos 2%

[0015] Methapon 38%

[0016] Acetone 5%

[0017] Cyclohexanone 10% 500#10%

[0018] Xylene make up to 100%

[0019] The pesticide composition can also be made into different application forms, including emulsifiable concentrate, wettable powder, microemulsion, and water-dispersible granule. The cumulative mass percentage of both chlorpyrifos and methidon accounts for 40% of the total mass. When processed into emulsifiable concentrate, operate according to the following process:

[0020] First, dissolve the original drug in some organic solvents such as xylene and methanol in proportion, fully dissolve it, then add an emulsifier to fully stir, then make up 100% of the amount of xylene and other solvents, and fully stir; finally pass the inspection and produce the product Package.

Embodiment 2

[0022] 40% chlorpyrifos · chlorpyrifos, that is, wettable powder with a mass ratio of 3:1

[0023] Chlorpyrifos 30%

[0024] Methapon 10%

[0025] Sodium Lauryl Sulfate 2%

[0026] Sodium lignosulfonate 6%

[0027] Sodium methylene bis-naphthalene sulfonate 8%

[0028] Kaolin supplemented to 100%

[0029] The pesticide composition can be made into different application forms, including emulsifiable concentrate, wettable powder, microemulsion, and water-dispersible granule. The cumulative mass percentage of both chlorpyrifos and methidon accounts for 40% of the total mass. When processed into wettable powder, operate according to the following process:

[0030] Firstly, mix the original drug, additives and fillers in proportion, stir them thoroughly, and then pulverize them. After passing the inspection, the wettable powder can be packaged.

Embodiment 3

[0032] 40% chlorpyrifos · chlorpyrifos, that is, the microemulsion with a mass ratio of 39:1

[0033] Conventional process composition, of which

[0034] Chlorpyrifos 39%

[0035] Methapon 1%

[0036] Acetone 10%

[0037] Glycerin 5%

[0038] Calcium dodecylbenzenesulfonate 10%

[0039] Farm Milk 0203B 20%

[0040] Water make up to 100%

[0041] The pesticide composition can be made into different application forms, including emulsifiable concentrate, wettable powder, microemulsion, and water-dispersible granule. The cumulative mass percentage of both chlorpyrifos and methidon accounts for 40% of the total mass.

Abstract

The invention discloses a pesticide composition containing chlorpyrifos and methidathion. The pesticide composition comprises active ingredients, namely the chlorpyrifos and the methidathion in a mass ratio of (50:1)-(1:50), preferably (1:20)-(40:1). The chlorpyrifos and the methidathion account for 3 to 60 mass percent of the composition. The pesticide composition containing the chlorpyrifos and the methidathion can be used for preventing and controlling various pests in agriculture, greening, forestry and the like, and is particularly effective for scale insects. By compounding the two active ingredients, a prevention effect is enhanced, the using amount of the active ingredients is reduced, and the generation time of pesticide resistance of pests such as the scale insects and the like is delayed.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition which takes chlorpyrifos and methidon as active ingredients and is effective against various agricultural, gardening and forest pests, especially scale insects. Background technique [0002] Scale insects are the main pests of plants such as orchards, tea gardens, trees and flowers. Due to the wax layer on the body, the control effect is often not good, and they damage a variety of plants to varying degrees. In severe cases, they often cause fallen leaves, flowers and fruits, affecting the yield and quality of plants. quality. At present, commonly used medicaments such as inorganic pharmaceutics lime sulfur, organophosphorus dimethoate, and phoxim cannot achieve ideal control effects when used alone. The only medicament for controlling scale insects in the market is methidon, and it is expensive. [0003] Chlorpyrifos is an organic phosphate broad-spectrum inse...
