Embodiment 1

[0021] Embodiment 1: Configure 18% imophos-cantharidin emulsifiable concentrate.

[0022] According to weight percentage, imophos (commercially available, in powder form, with a purity of 99%, the same below) 17% (100 percent, the same below), cantharidin 1% (100 percent, the same below), and agricultural milk 1600 No. 12% emulsifier and 70% toluene are added to the preparation kettle in sequence, and stirred for 1 hour at a temperature of 20-30°C to obtain the product. After testing, the imidophos-cantharidin EC is a light yellow homogeneous liquid without suspended solids and visible impurities, the internal quality is up to standard, and the pH, moisture, emulsion stability, and heat storage and refrigeration tests are qualified.

Embodiment 2

[0023] Embodiment 2: configuring 6% imophos-cantharidin emulsifiable concentrate.

[0024] Add 5.8% of imidophos, 0.2% of cantharidin, 19% of Nongru No. 1600 emulsifier, and 75% of xylene into the preparation kettle in sequence, and stir at a temperature of 20-30°C for half an hour, that is, have to. After testing, the imidophos-cantharidin EC is a light yellow homogeneous liquid without suspended solids and visible impurities, the internal quality is up to standard, and the pH, moisture, emulsion stability, and heat storage and refrigeration tests are qualified.

Embodiment 3

[0025] Embodiment 3: configuring 15% imophos-cantharidin emulsifiable concentrate.

[0026] 14.5% by weight of imophos, 0.5% of cantharidin, No. 1600 emulsifier 20% of agricultural milk, 65% of the mixed solvent of dimethylbenzene and toluene (the two are mixed in any proportion) are added in the modulation kettle successively, at 20 After stirring for half an hour at a temperature of -30°C, it is ready. After testing, the imidophos-cantharidin EC is a light yellow homogeneous liquid without suspended solids and visible impurities, the internal quality is up to standard, and the pH, moisture, emulsion stability, and heat storage and refrigeration tests are qualified.

Abstract

The invention provides a phosmet and cantharidin insecticidal composition which is prepared from the following components by weight percentage: 4-60% of phosmet and 0.1-2% of cantharidin which are taken effective active components, and 39-95% of auxiliary component. In the invention, the phosmet is compounded with the cantharidin to generate obvious synergistic effect, thus effectively relieving the generation of pest resistance, prolonging the service life of insecticide varieties, reducing the insecticide consumption, lowering the field application cost of insecticide, and ensuring safety of people and livestock and current crops and succeeding crops. Farmland tests show that the phosmet and cantharidin insecticidal composition has obvious control effect on cabbage caterpillar, aphid and diamondback moth in vegetables, cotton bollworm, aphid and mite in cotton, citrus scale insect, soybean pod borer and the like. The compounded dosage form has stable properties, good low-temperaturestability and good thermal storage stability and meets the industrial standard.

Description

technical field [0001] The invention relates to insecticides, in particular to a compound composition of imophos and cantharidin, an insecticidal active ingredient of animal 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 losses to agric...
