Problems solved by technology

[0002] The problem of resistance to agricultural diseases, insect pests and weeds is a global problem, and has always been a key topic of concern to agricultural science and technology workers; with the continuation of chemical control of agricultural diseases, insect pests and weeds year after year, the increase in the use of pesticides and unscientific With the use of pesticides, the resistance of pests is becoming more and more serious, and the types of pests that develop resistance are increasing; at the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased pesticide costs for farmers, which is not conducive to the sustainable development of agriculture; therefore, The research and development of high-efficiency, low-toxicity, and environmental-friendly insecticides and pesticides is of positive significance to the sustainable development of agriculture
[0006] The combination application of tefluthrin and cyromazine has no report yet

Embodiment 1

[0020] The insecticidal composition described in embodiment 1 is a suspension concentrate, and the percentages of each component are respectively:

[0021]

[0022] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add tefluthrin and cyromazine, grind in a ball mill for 2-3 hours, so that the particle diameter is below 5mm , to prepare 32% tefluthrin · cyromazine suspension concentrate preparation.

Embodiment 2

[0023] Embodiment 2 The insecticidal composition is an emulsion in water, and the percentages of each component are respectively:

[0024]

[0025]

[0026] The specific operation steps are as follows: firstly mix tefluthrin, cyromazine, mesitylene and sorbitan fatty acid ester to dissolve into a uniform oil phase. Then mix some water and other additives together to dissolve into a uniform water phase. Then add the oil phase to the water phase while stirring at high speed in the reaction kettle, slowly add water until the phase inversion point is reached, then perform high-speed shearing, and add the remaining water, and shear for about 30 minutes to obtain 22% teflumethrin Ester·cyromazine aqueous emulsion preparation.

Embodiment 3

[0027] The insecticidal composition described in embodiment 3 is a microemulsion, and the percentages of each component are respectively:

[0028]

[0029] The specific operation steps are: first completely dissolve tefluthrin and cyromazine with fatty acid methyl ester, then add other additives, mix evenly, finally add water, after fully stirring, 18% tefluthrin can be obtained · Cyromazine microemulsion preparation.

Abstract

The invention discloses an insecticide composition containing tefluthrin and cyromazine. The insecticide composition comprises effective components tefluthrin and cyromazine, wherein the weight ratio of tefluthrin to cyromazine is (1:15)-(15:1); the total weight of tefluthrin and cyromazine accounts for 2-80% of the insecticide composition in percentage by weight. The insecticide composition containing tefluthrin and cyromazine can be prepared as a suspending agent, a micro-capsule suspending agent, emulsion in water, microemulsion, an ultra-low volume liquid, wettable powder, an aqueous dispersion granular agent and granules according to practical application demands, and can be applied to prevention and treatment on chive maggots in Chinese chive fields.

Description

technical field [0001] The invention relates to an insecticidal composition containing tefluthrin and cyromazine, which uses tefluthrin and cyromazine as active ingredients and is applied to leek fields to prevent and control leek maggots. Background technique [0002] The problem of resistance to agricultural diseases, insect pests and weeds is a global problem, and has always been a key topic of concern to agricultural science and technology workers; with the continuation of chemical control of agricultural diseases, insect pests and weeds year after year, the increase in the use of pesticides and unscientific With the use of pesticides, the resistance of pests is becoming more and more serious, and the types of pests that develop resistance are increasing; at the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased pesticide costs for farmers, which is not conducive to the sust...
