Abstract

The invention relates to a novel nematicidal compound which comprises the following active ingredients: a compound in the formula I and tioxazafen, wherein the weight ratio of the compound in the formula I and the tioxazafen is 1: 30-30: 1, and preferably, the weight ratio is 1: 10-10: 1. The active ingredients of the nematicidal compound has an obvious synergistic effect in prevention of variouscrop root knot 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 root knot 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 preventioneffect 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 pesticides, and in particular relates to a nematicide composition containing tioxazafen and its application. 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-volatile. The former acts as fumigation and the latter ...
