Description

Insecticidal composition containing aliphatic amine polymer

Technical Field

The invention belongs to the field of pesticides for controlling crop pests, and relates to a pesticide composition containing an aliphatic amine polymer, an auxiliary agent and a solvent, which comprises the following components: (A) at least one aliphatic amine polymer, (B) at least one auxiliary agent, (C) at least one solvent. The present invention also relates to methods of treating insect infections in plants, plant parts and/or the surrounding environment by applying the pesticidal compositions.

Background

Insecticides are a broad class of pesticides used primarily to control pests that are harmful to crops. The insecticides are of various types and have different effects on pests, and can be divided into the following categories according to the action modes: (1) stomach poison, a medicament which enters the body of a pest through the digestive system of the pest and causes the pest to be poisoned and dead, and is mainly used for preventing and controlling the pest which is bitten, gnawed and eaten by a chewing mouthpart. (2) Contact insecticide, an agent which is poisoned and killed by contacting the pest epidermis or penetrating into the pest body, such as deltamethrin, etc. (3) Systemic agents, which are agents absorbed into the plant body through the leaves, stems, roots of the plant, transported, scattered, retained in the plant body, or produce metabolites, and cause the pests to die by poisoning when they eat plant tissues or sap. Mainly used for preventing and controlling pests with piercing-sucking mouthparts. (4) Fumigant, which is a drug that enters the body of a pest through the respiratory system of the pest in a gaseous state to poison the pest. Mainly used for killing pests of nursery stocks, pests of storage sites and pests of warehouse seeds, such as sulfuryl fluoride and the like. (5) The attractant basically has no toxic effect on pests, but can attract the pests to come ahead so as to intensively eliminate the pests, such as insect sex attractant, sugar vinegar and the like. (6) The antifeedant can destroy the normal physiological function of pests after eating, eliminate appetite and kill hunger, such as antifeedant. (7) The sterilizing agent is a chemical which can make eggs laid by pests unable to hatch after the pests eat or contact with a certain dose, such as hexaphosphamide, camptothecin and the like, and has obvious sterilizing effect on the houseflies. (8) Insect growth regulators, agents that reduce or kill the ability of an insect to live by disrupting its normal growth, such as the insect chitin synthesis inhibitor diflubenzuron.

In recent years, with the repeated use of a large amount of pesticides, pests have high resistance to several pesticides, such as the problem of imidacloprid resistance, and Zhang Xiao Lei is equal to 2009-2014, the rice steeping method is adopted to monitor that the 5 brown planthopper population in the rice district in Hubei province has high-level resistance RR = 101.8-1239.4 to imidacloprid, and the resistance is in an increasing trend. Zhang Shuai and the like monitor that the times of resistance of cotton aphid species groups in fields of Qiu county in Hebei, Binzhou in Shandong and West Hua in Henan are all more than 900 times to imidacloprid, and particularly the times of resistance of the West Hua species groups are increased from 973.4 times to 2207.6 times. From these data, it was shown that the development of resistance to pesticides is inevitable and explosive.

The invention utilizes the functions of spreading, wetting, permeating and the like of the surfactant, researches on the aspects of the epidermis structure of pests and the like from the research of a physical pest killing mode, utilizes the combination of different action modes to kill the pests or lose the activity of the pests in the modes of dissolving the pest epidermis, closing pores, dissolving membrane wings and the like, thereby protecting crops from being damaged.

The Ministry of agriculture of 3.14.2016, put forward the goal of 'double reduction', namely, the reduction of chemical pesticide and chemical fertilizer. The invention meets one of the double reduction targets proposed by the nation and reduces the use of pesticides.

Solves the technical problem

The invention aims to solve the technical problems that: under the condition of not using pesticides, pests are killed in a physical mode, the population number of the pests is controlled, and the method is environment-friendly.

The method is a pesticide and fertilizer application reduction plan of the corresponding country, improves the yield of crops, ensures the safety of the environment and human bodies, reduces the use amount of pesticides, researches the physical prevention and control technology of the auxiliary agent on pests, and ensures that the pests are damaged or destroyed to a certain extent through different action modes of the auxiliary agent, such as sealing of pores of the pests, dissolution of epidermis, dissolution of membrane wings and the like, thereby achieving the purpose of controlling the number of the pests and achieving the purpose of protecting the crops. The auxiliary agent and the composition are environment-friendly, and have the functions of killing insects and preventing diseases through the synergistic effect of the auxiliary agent. The technical key point of the technology is that the spraying is uniform, so that the spraying liquid is contacted with the insect body to play a role.
