Problems solved by technology

[0003] However, the biological control method is limited by natural conditions, artificial cultivation is difficult, and the relationship between biological species is complicated, so the control effect is not ideal; the chemical control method is due to the long-term use of toxic pesticides in large quantities. On the one hand, pests and diseases gradually develop resistance problems, the incidence of pests and diseases has increased significantly, and on the other hand, pesticides will remain excessively on crops, which has a greater impact on humans and the environment

preparation example Construction

[0060] The second aspect of the present invention provides a method for preparing a pesticide composition, at least including the following steps: stirring and mixing mineral oil, multi-carbon chain organic matter, dispersant, and auxiliary agents to prepare the pesticide composition.

[0061] The present invention jointly prepares the pesticide composition through the synergistic effect between mineral oil, multi-carbon chain organic matter, dispersant and auxiliary agent, and the oil film formed by the prepared pesticide composition can suffocate pests. Alcohol, n-butanol, 2-(2-hydroxyethylamino)-1-propanamine are as additives, when the weight ratio of n-propanol, n-butanol, 2-(2-hydroxyethylamino)-1-propanamine When the ratio is 1:2:3, the prepared pesticide composition can dissolve the waxy layer on the body surface of the pests. As a multi-carbon chain organic matter, under a specific ratio, there is a good synergistic adsorption between the additive and the multi-carbon ...

[0070] The weight ratio of the sodium carboxymethyl cellulose and sodium alginate is 1:2.

[0071] The auxiliary agent is n-propanol, n-butanol, 2-(2-hydroxyethylamino)-1-propanamine.

[0072] The weight ratio of n-propanol, n-b...

Embodiment 2

[0075] Example 2 of the present invention provides a pesticide composition, comprising the following components in parts by weight: 90 parts of mineral oil, 1 part of multi-carbon chain organic matter, 0.1 part of dispersant, and 0.1 part of auxiliary agent.

[0076] The multi-carbon chain organic matter is sodium dodecylbenzenesulfonate, tetradecyl ammonium chloride, and cetyl alcohol polyoxyethylene ether.

[0077] The weight ratio of sodium dodecylbenzenesulfonate, tetradecyl ammonium chloride and cetyl polyoxyethylene ether is 1:0.2:0.1.

[0078] The dispersant is sodium carboxymethyl cellulose and sodium alginate.

[0079] The molecular weight of the sodium carboxymethyl cellulose is 500, and the molecular weight of the sodium alginate is 200.

[0080] The weight ratio of the sodium carboxymethyl cellulose and sodium alginate is 1:1.

[0081] The auxiliary agent is n-propanol, n-butanol, 2-(2-hydroxyethylamino)-1-propanamine.

[0082] The weight ratio of n-propanol, n-...

Abstract

The invention relates to the technical field of pesticides, in particular to a pesticide composition and a preparation method thereof. The pesticide composition at least comprises the following components in parts by weight: 90-100 parts of mineral oil, 1-8 parts of a multi-carbon-chain organic matter, 0.1-1 part of a dispersing agent and 0.1-1 part of an auxiliary agent. The pesticide compositionis prepared from the mineral oil, the multi-carbon-chain organic matter, the dispersing agent and the auxiliary agent; the mineral oil, the multi-carbon-chain organic matter, the dispersing agent andthe auxiliary agent have a relatively good synergistic effect; the prepared pesticide composition can control various pests, has high activity on red spiders, panonychus citri, aphids, bemisia tabaci, whiteflies, brachymyza cunea, rust mites and the like on vegetables, fruit trees, cotton, rice and other crops, and has excellent control effect and long control effect time; the dosage is reduced greatly; and in addition, the effect of preventing and controlling pests through physical action is achieved, almost no residue is left on crops, the pesticide composition is harmless to human bodies and the environment, drug resistance of pests is not induced.

Description

technical field [0001] The invention relates to the technical field of pesticides, more specifically, the invention relates to a pesticide composition and a preparation method thereof. Background technique [0002] Various insect pests in crops seriously affect the yield of crops. At present, the methods of pest control mainly include biological control method and chemical control method. Biological control method refers to the method of using organisms and their products to prevent and control pests, including the use of parasitic natural enemies and predatory natural enemies of pests to control pests, and the use of pest sterility and hormones to achieve the purpose of pest control; chemical control methods are also called chemical control methods. , is the method of using pesticides to control pests. [0003] However, the biological control method is limited by natural conditions, artificial cultivation is difficult, and the relationship between biological species is co...
