Pesticide composition containing graphene oxide

Abstract

The invention provides a preparation method of a pesticide composition containing graphene oxide. The insecticide comprises the following components in percentage by mass: 5%-10% of chlorfenapyr serving as a component A, 0.5%-10% of indoxacarb, emamectin benzoate, methoxyfenozide or chlorantraniliprole serving as a component B, 10%-20% of graphene oxide serving as a synergist, 2%-5% of sodium alkyl sulfate serving as an emulsifier, 1%-5% of polyoxyethylene ether serving as a dispersing agent, 1%-5% of ethylene glycol or propylene glycol serving as an anti-freezing agent, 0.2%-0.5% of sodium benzoate serving as a preservative, 0.2%-0.5% of magnesium aluminum silicate serving as a thickening agent, 1%-3% of organic silicon serving as a defoaming agent, and the balance of deionized water. Thepesticide composition is prepared by stirring, mixing and grinding.

Description

technical field

[0001] The invention relates to the field of pesticides for crops, in particular to a pesticide composition containing graphene oxide and a preparation method thereof. Background technique

[0002] During the growth of crops, pesticides such as chlorfenapyr, indoxacarb, emamectin benzoate, methoxyfenozide, and chlorantraniliprole are commonly used for pest control. However, the repeated use of the above-mentioned pesticides has gradually increased the resistance of the pests. In some areas, the beet armyworm population has a high level of resistance to the bisamide agent chlorantraniliprole, and a moderate to high level of resistance to indoxacarb. Insect growth regulators such as methoxyfenozide had low to moderate levels of resistance. The effect of using a single variety of this type of pesticide to control crop pests is not satisfactory.

[0003] In order to increase the control effect, the above two pesticides have to be used in combination. However, ...

Examples

Embodiment 1

[0025] Example 1: A pesticide composition containing graphene oxide, comprising the following components by mass percentage: chlorfenapyr 10%, indoxacarb 10%, graphene oxide 15%, and alkyl sodium sulfate 2.5%, polyoxygen Vinyl ether 2.5%, organosilicon 1.5%, sodium benzoate 0.3%, magnesium aluminum silicate 0.5%, ethylene glycol 1.8%, supplemented with deionized water, and processed by stirring, mixing and grinding. It can better control vegetable pests such as diamondback moth, Spodoptera litura, and Cabbage Spodoptera.

Embodiment 2

[0026] Example 2: A pesticide composition containing graphene oxide, comprising the following components in mass percent: chlorfenapyr 10%, emamectin 5%, graphene oxide 15%, and alkyl sodium sulfate 2%, poly Oxyethylene ether 2.5%, organosilicon 1.5%, sodium benzoate 0.3%, magnesium aluminum silicate 0.5%, ethylene glycol 1.8%, supplemented with deionized water, and processed by stirring, mixing, and grinding. It can effectively control various pests on fruit trees, cotton and other crops.

Embodiment 3

[0027] Example 3: A pesticide composition containing graphene oxide, comprising the following components in mass percentage: chlorfenapyr 5%, methoxyfenozide 10%, graphene oxide 15% and alkyl sodium sulfate 2%, Polyoxyethylene ether 2.8%, organosilicon 1.7%, sodium benzoate 0.5%, magnesium aluminum silicate 0.5%, propylene glycol 2.6%, supplemented with deionized water, and processed by stirring, mixing, and grinding. It can effectively control various pests of field crops.
