Embodiment 1

[0022] Embodiment 1: Combined application of soybean lecithin and diafenthiuron.

[0023] The contents of the following substances are all percentages by weight: soybean lecithin 2%, diafenthiuron 40%, polyoxyethylene polyoxypropylene ether block copolymer 10%, pull-off powder 5%, carboxymethyl cellulose 1.5% %, potassium sorbate 0.3%, silicone oil 0.1%, ethylene glycol 2.5%, and deionized water to make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare a synergistic 40% diafenthiuron suspending agent.

[0024] Use the above-mentioned synergistic 40% diafenthiuron suspending agent to prevent and control mango tree spider mite: 40% diafenthiuron suspending agent containing 4% soybean lecithin is used 1500 times, and the control effect of 5d, 10d, and 20d after treatment is 93.81% , 96.07%, 87.20%; 40% diafenthiuron suspension without soybean lecithin was used 1500 times, and t...

Embodiment 2

[0025] Example 2: Combined application of soybean lecithin and etoxazole.

[0026] The contents of the following substances are all percentages by weight: soybean lecithin 1%, etoxazole 10%, polyoxyethylene polyoxypropylene ether block copolymer 10%, pull-off powder 5%, carboxymethyl cellulose 1.5% %, potassium sorbate 0.3%, silicone oil 0.1%, ethylene glycol 2.5%, and deionized water to make up to 100%. The above-mentioned materials are mixed in proportion, sanded in a sand mill, and dispersed evenly by high-speed shearing to prepare a synergistic 10% etoxazole suspension concentrate.

[0027] Use the above synergistic 10% etoxazole suspension to prevent and control peanut cinnabar spider mite: 10% etoxazole suspension containing 1% soybean lecithin is used 2000 times, and the control effect is 86.41% after 5 days, 10 days and 20 days after treatment , 90.17%, 93.29%; 10% etoxazole suspension without soybean lecithin was used 2000 times, and the control effects were 80.94%, ...

Embodiment 3

[0028] Example 3: Combined application of soybean lecithin, etoxazole and diafenthiuron.

[0029] The contents of the following substances are all percentages by weight: soybean lecithin 2.25%, etoxazole 15%, diafenthiuron 30%, polyoxyethylene polyoxypropylene ether block copolymer 10%, pull-off powder 5%, Carboxymethyl cellulose 1.5%, potassium sorbate 0.3%, silicone oil 0.1%, ethylene glycol 2.5%, deionized water to make up to 100%. The above-mentioned materials are mixed in proportion, sand-milled in a sand mill, and dispersed evenly by high-speed shearing to prepare a synergistic 45% etoxazole diafenthiuron suspending agent.

[0030] Use the above-mentioned synergistic 45% etoxazole diafenthiuron suspending agent to prevent and treat Tetranychus cinnabarinus: 45% etoxazole diafenthiuron suspending agent containing 2.25% soybean lecithin is used 5000 times, after 5 days, 10d, 20d control effects were 93.28%, 95.04%, 91.72%; 45% etoxazole diafenthiuron suspension without so...

Abstract

The invention discloses an acaricide containing soybean lecithin. The acaricide is prepared from one or two of active ingredients of diafenthiuron and etoxazole and further comprises soybean lecithin,and the weight ratio of the soybean lecithin to the active ingredients in the acaricide is 1: 1-1: 600. The acaricide disclosed by the invention is excellent in effect of preventing and treating theagricultural red spider mites and long in lasting period, is safe to the crops, enables the usage amount of pesticides and the usage cost to be reduced and the pollution to the environment to be relived, delays, prevent and control the generation of the drug resistance of drugs, and has prolonged service life.

Description

technical field [0001] The invention relates to the field of pesticide application, in particular to an acaricide containing soybean lecithin, and the acaricide active ingredient is one or a combination of diafenthiuron and etoxazole. Background technique [0002] Diafenthiuron, by interfering with the energy metabolism of the nervous system, destroys the basic functions of the nervous system and inhibits chitin synthesis. [0003] Etoxazole inhibits the embryogenesis of mite eggs and the moulting process from larvae to adults. It is effective for eggs and larvae, but not for adults, but it has a good sterile effect on female adults. [0004] Soy lecithin (Lecithin High Potency, also known as soybean lecithin), is a by-product in the process of refining soybean oil, which is obtained by solvent extraction, centrifugation and alcohol washing. The granular soybean soybean lecithin on the market is the phospholipid precipitated from soybean oil during the degumming process, an...
