Nematicidal compound containing iprodione

Abstract

The invention relates to a nematicidal compound which comprises the following active ingredients: a compound in the formula I and iprodione, wherein the weight ratio of the compound in the formula I and the iprodione is 30: 1-1: 20, and preferably, the weight ratio is 10: 1-5: 1. The active ingredients of the nematicidal compound has an obvious synergistic effect in prevention of various crop rootknot nematode diseases within a compound scope and is suitable for preventing various nematodes such as a wheat root knot nematode, a wheat cyst nematode, a citrus root knot nematode, a cucumber rootknot nematode, a tomato root knot nematode, a chili root knot nematode, a peanut root knot nematode, a soybean root knot nematode and the like. The nematicidal compound is good in prevention effect and long in lasting period, so that the nematicidal compound is worthy of promotion and application.

Description

technical field [0001] The invention belongs to the field of pesticide nematodes, and in particular relates to a nematicidal composition containing iprodione and its application for preventing and controlling crop nematodes. Background technique [0002] Nematodes belong to the nematode phylum Nematodes, and they are small in size and can be observed under a microscope. There are about 3,000 species of nematodes that are harmful to plants, most of which live in the soil, and some are parasitic in plants. Nematodes 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, causing great economic losses. The use of pesticides to control nematodes is an effective method commonly used in modern agriculture. It is generally used for soil treatment or seed treatment. There are two types of nematicides: volatile and non-...

AI Technical Summary

Problems solved by technology

[0005] Iprodione belongs to the dicarboximide family of high-efficiency, broad-spectrum, contact-killing fungicides. It is a low-toxicity fungicide and has a high control effect on many fungal diseases. In most cases, nematodes are also accompanied by soil-borne diseases. However, soil-borne diseases and nematode spores are more serious in the plots of heavy cropping for many years, accompanied by phenomena such as soil compaction and soil fertility degradation. It has been shown that iprodione also has certain activity against plant nematodes. The effect of bacteriocarbamide on controlling plant nematodes is not ideal, and it is easy to lead to the occurrence of nematode resistance, which is not conducive to the sustainable development of agricultural ecology

[0006] The inventor of the present application has carried out in-depth research on this basis through a large number of experimental active ingredients and field drug efficacy tests, and found that the compound of the above formula (1) and iprodione is compounded in a certain range against root-knot nematodes. The prevention and treatment effect of the present invention shows a synergistic effect, and the present invention has been completed through further research, and no relevant reports about the compounding of the two have been found at present.
