Cinnamyl aldehyde-containing pesticide composition as well as preparation method and application thereof

Abstract

The invention relates to the technical field of pesticides, in particular to a cinnamyl aldehyde-containing pesticide composition as well as a preparation method and application thereof. The pesticidecomposition disclosed by the invention improves the problem of drug resistance of an existing nematicide, has equivalent root-knot nematode activity after treatment for 1 day, cause no recovery phenomenon of root-knot nematode as time goes on, has high safety to plants, can be applied in the whole growth period of the plants, and can effectively prevent and remove soil-borne diseases. The inventor accidentally finds that a component A and a component B of the pesticide composition have a remarkable synergistic effect, the cotoxicity coefficient of the composition is 200 or above, the pesticide effect is improved by 2-3 times, and the pesticide composition has a remarkable synergistic effect. Moreover, the pesticide composition disclosed by the invention also improves the problems of strong smell, no environmental protection, phytotoxicity and the like of a medicament, and is suitable for a wider range of crops.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition containing cinnamaldehyde and its preparation method and application. Background technique [0002] Nematodes belong to the nematode class Nematodes, and they are small in size and can be observed under a microscope. Most nematodes live in the soil, and some are parasitic in plants. They spread through soil or seeds, can damage the root system of plants or invade the organs of the aboveground parts, affect the growth and development of crops, and indirectly spread diseases caused by other microorganisms. cause great economic losses. The use of pesticides to control nematodes is a commonly used method in modern agriculture, and is generally used for soil treatment or seed treatment. However, the active ingredients in nematicides are often non-specific and thus may act on other beneficial organisms present in the crop. Moreover, such active ingredients...

AI Technical Summary

Problems solved by technology

Among them, abamectin has been used for a long time, nematodes have great drug resistance, the effect is poor, and it is easy to degrade in the soil, and the duration of effect is particularly short

Thiazophos has been used for a long time, nematode resistance is increasing, and the effect is declining year by year

Moreover, thiazophosphine has a strong smell, and its production and use do not meet environmental protection requirements, and there is also a risk of phytotoxicity to crops

Moreover, most of the above-mentioned nematicides are highly toxic to humans and animals

For example, although Chinese patent documents CN 103329932A and CN 103430950A disclose nematicide composition products containing furfural, furfural was classified as a Class 3 carcinogen by the International Agency for Research on Cancer (IARC) of the World Health Organization on October 27, 2017. In the list (category 3: the carcinogenicity to humans cannot be classified, that is, suspected to be carcinogenic to humans), the environmental risk is relatively high

The compound is only registered in the United States for the fumigation of ornamental plants grown in greenhouses and plant soil for specific non-food purposes, as well as pre-emergence soil, and there are safety issues for plants when used in high doses
