Problems solved by technology

However, in most cases, the compounding effects of pesticides are additive, and there are fewer compounds showing synergistic effects, especially those with very obvious synergistic effects and high co-toxicity coefficients.
However, there is no report on the compounding of these two active ingredients diafenthiuron and fenoxycarb at present.

Embodiment 1

[0040] Example 1 20% diafenthiuron · fenoxycarb suspension

[0041]The formula is: active ingredient diafenthiuron 10%, fenoxycarb 10%, dispersant acrylic acid-maleic anhydride copolymer 2%, nonylphenol polyoxyethylene ether 2%, wetting agent sodium alkylnaphthalene sulfonate 1 %, sodium ethyl laurate sulfonate 2%, thickener xanthan gum 0.5%, defoamer silicone oil 1%, antifreeze agent ethylene glycol 2%, water to make up 100%.

[0042] Preparation method: high-speed shear the dispersant, wetting agent, defoamer and water in the above formula, mix evenly, then add diafenthiuron and fenoxycarb, and sand in a sand mill. Frequently check the particle size of the material, sand mill until the particle size is 3-5μm; add the thickener to the antifreeze and mix evenly, then add the mixture of thickener and antifreeze to the liquid mixture after sanding, By high-speed shearing and mixing evenly, 20% diafenthiuron · fenoxycarb suspension concentrate product is prepared.

Embodiment 2

[0043] Example 2 30% diafenthiuron · fenoxycarb suspension

[0044] The formula is: active ingredient diafenthiuron 20%, fenoxycarb 10%, dispersant acrylic acid-maleic anhydride copolymer 3%, nonylphenol polyoxyethylene ether 1%, wetting agent sodium alkylnaphthalene sulfonate 2 %, sodium ethyl laurate sulfonate 2%, thickener xanthan gum 0.5%, defoamer silicone oil 1%, antifreeze agent ethylene glycol 2%, water to make up 100%. The preparation method is the same as in Example 1.

Embodiment 3

[0045] Example 3 40% diafenthiuron · fenoxycarb suspension

[0046] The formula is: active ingredient diafenthiuron 30%, fenoxycarb 10%, dispersant acrylic acid-maleic anhydride copolymer 3%, nonylphenol polyoxyethylene ether 1%, wetting agent sodium alkylnaphthalene sulfonate 1% %, sodium ethyl laurate sulfonate 4%, thickener xanthan gum 0.5%, defoamer silicone oil 1%, antifreeze agent ethylene glycol 2%, water to make up 100%. The preparation method is the same as in Example 1.

Abstract

The invention discloses an insecticidal composition of diafenthiuron and fenoxycarb and an application thereof. The insecticidal composition is compounded with diafenthiuron and fenoxycarb, and has a good synergistic effect, wherein butyl The mass ratio of ether urea and fenoxycarb is 1-10:1, preferably 1-5:1. The insecticidal composition of the present invention expands the insecticidal spectrum, improves the persistence period of the drug, avoids the generation of drug resistance, and has great effects in preventing and controlling Lepidoptera pests such as cotton bollworms, diamondback moths, stem borers, and noctuids in food crops and vegetables. The good effect is beneficial to the sustainable development of the environment, and the preparation process of the composition is environmentally friendly, and there are no safety and pollution problems.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition of diafenthiuron and fenoxycarb and the application of the composition in preventing and controlling insect pests of food crops and vegetables, and belongs to the technical field of pesticides. Background technique [0002] Diafenthiuron (Diafenthiuron) is a new type of thiourea insecticide. The thiourea group on its molecular structure becomes a carbodiimide compound under the action of sunlight and the multifunctional oxidase in the insect body. Pest mite has strong poisonous ability, and it is a mitochondrial ATPase inhibitor. Its main mechanism of action is to interfere with the energy metabolism of the nervous system, hinder ATP synthesis, and destroy the basic functions of the nervous system. Diafenthiuron has systemic, contact killing, stomach poisoning and fumigation effects, and is widely used in field crops, fruit trees, vegetables and ornamenta...
