Embodiment 1

[0020] Embodiment 1: configure 18% imophos-azirachtin emulsifiable concentrate.

[0021] According to weight percentage, 17% (commercially available, in powder form, 99% purity, the same below), azadirachtin 1% (100 percent, the same below), Nongru Add 12% of No. 1600 emulsifier and 70% toluene to the preparation kettle in turn, and stir for 1 hour at a temperature of 20-30°C to obtain the product. After testing, the imidophos-azirachtin emulsifiable concentrate is a light yellow homogeneous liquid without suspended solids and visible impurities.

Embodiment 2

[0022] Embodiment 2: configuring 6% imophos-azirachtin emulsifiable concentrate.

[0023] Add 5.8% of imidophos, 0.2% of azadirachtin, 19% of Nongru No. 1600 emulsifier, and 75% of xylene into the preparation kettle in sequence, and stir for half an hour at a temperature of 20-30°C. Instantly. After testing, the imidophos-azirachtin emulsifiable concentrate is a light yellow homogeneous liquid without suspended solids and visible impurities.

Embodiment 3

[0024] Embodiment 3: configuring 15% imophos-azirachtin emulsifiable concentrate.

[0025] By weight percentage, 14.5% of imidophos, 0.5% of azadirachtin, 20% of Nongru No. 1600 emulsifier, 65% of the mixed solvent of xylene and toluene (the two are mixed in any proportion) are added in the preparation kettle successively, and After stirring for half an hour at a temperature of 20-30°C, it is ready. After testing, the imidophos-azirachtin emulsifiable concentrate is a light yellow homogeneous liquid without suspended solids and visible impurities.

Abstract

The invention relates to a compounded insecticidal composition which consists of an effective active component and an auxiliary component, wherein the effective active component consists of imidan and azadirachtin; and the compounded insecticidal composition comprises 4-60wt% of imidan, 0.1-2wt% of azadirachtin and 39-95wt% of the auxiliary component. According to the invention, after imidan and azadirachtin are compounded, an obvious synergistic action can be generated; and the compounded insecticidal composition can be used for effectively delaying the resistance generation of insect pests, effectively prolonging the variety service lives of farm chemicals, reducing the application quantity of the farm chemicals and lowering the field application costs of the farm chemicals, and is safe for human and livestock as well as current-reap crops and afterreap crops. Farmland experiments indicate that the compounded insecticidal composition has obvious prevention and treatment effects on the cabbage worms, plant louse and plutella xylostella which are positioned on vegetables, the cotton bollworms, plant louse and caro which are positioned on cotton, citrus icerya purchasi, soybean pod borer and the like; and the compounded insecticidal composition has stable dosage form property, good low-temperature stability and good heat storage stability, and meets the industry standard.

Description

technical field [0001] The invention relates to insecticides, in particular to a compound insecticidal composition of imophos and azadirachtin, an insecticidal active ingredient of plant origin. Background technique [0002] Pollution-free vegetables, tea, mulberry trees, and Chinese medicinal materials are the main economic crops in my country, and they are harmed by many harmful organisms during their growth. Sometimes a variety of pests occur at the same time. In particular, whitefly, cabbage caterpillar, mulberry looper and tea leafhopper have broken out and caused disasters in some areas of our country in recent years. In this case, if high-efficiency and low-toxic pesticides cannot meet the timely supply of the market, farmers can only abuse high-toxic pesticides for emergency control. Although the pests are controlled in a short period of time, it destroys the ecology, harms human health, and affects the quality of agricultural products. Exports have brought great lo...
