Embodiment 1

[0023] A phoxim insecticide made from raw materials of the following weights:

[0024] Phoxim 35kg;

[0025] Emulsifier 5kg;

[0026] Solvent 60kg.

[0027] The emulsifier is a mixture of tristyrene phenol polyoxyethylene polyoxypropylene ether, styrene phenol polyoxyethylene ether, and bisphenylethylphenol phosphate polyoxyethylene ether in a mass ratio of 1:1:0.8.

[0028] The solvent is sec-butyl acetate.

Embodiment 2

[0030] A phoxim insecticide made from raw materials of the following weights:

[0031] Phoxim 40.5kg;

[0032] Emulsifier 8kg;

[0033] Solvent 51.5kg.

[0034] The emulsifier is a mixture of tristyrene phenol polyoxyethylene polyoxypropylene ether, styrene phenol polyoxyethylene ether, and bisphenylethylphenol phosphate polyoxyethylene ether in a mass ratio of 1:1:0.9.

[0035] The solvent is sec-butyl acetate.

Embodiment 3

[0037] A phoxim insecticide made from raw materials of the following weights:

[0038] Phoxim 45kg;

[0039] Emulsifier 10kg;

[0040] Solvent 45kg.

[0041] The emulsifier is a mixture of tristyrene phenol polyoxyethylene polyoxypropylene ether, styrene phenol polyoxyethylene ether, and bisphenylethylphenol phosphate polyoxyethylene ether in a mass ratio of 1:1:1.

[0042] The solvent is sec-butyl acetate.

[0043] 1. Configure the liquid medicine

[0044] 40% phoxim EC (5000kg)

[0045] The weight of phoxim is 2025kg (according to 40.5%);

[0046] The weight of emulsifier is 400kg (according to 8%);

[0047] Solvent weight 2575 kg.

[0048] 2. Test process

[0049] The control effect is calculated using the following diseased plant rate (%).

[0050] Rate of diseased plants (%) = number of diseased plants / total number of investigated plants × 100%

[0051] Control effect (%) = (1- treatment incidence rate / control incidence rate) × 100%

Abstract

The invention discloses a phoxim insecticide, which is prepared from the following raw materials in percentage by weight: 35-45% of phoxim, 5-10% of an emulsifier, and the balance of a solvent. The invention discloses an application of the phoxim insecticide in preventing and treating of cnaphalocrocis medinalis guenee. Through a large number of indoor activity tests and field pesticide effect tests, the results show that 40% phoxim has an obvious synergistic effect on prevention and treatment of various crop diseases, can delay the resistance of pathogenic bacteria, reduce the usage amount ofpesticide active ingredients and improve the prevention and treatment effect, and is safe to crops.

Description

technical field [0001] The invention relates to a pesticide insecticide, in particular to a phoxim insecticide and its application. Background technique [0002] In agricultural production, the most likely problem in pest control is the generation of pest resistance. Commonly used pesticides such as chlorpyrifos, methomyl, cypermethrin, dichlorvos, etc., either have good quick-acting properties and poor persistence, or have good persistence and poor quick-acting properties. Moreover, the long-term use of these ingredients has resulted in extremely high pest resistance and reduced control efficiency. In some serious areas, the yield loss due to the increase in pest damage can reach more than 30% of the normal yield. [0003] Methamidophos is a highly toxic organophosphorus insecticide and acaricide with the largest output in my country at present. It has contact killing, stomach poisoning, systemic and certain fumigation effects on pests, and it also has an ovicidal effect o...
