Problems solved by technology

[0004] 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
And there is no relevant report about the combination of iprodione and tioxazafen

Embodiment 1

[0025] 1. Example 1: 12% tioxazafen · iprodione granules (1:5)

[0026] Tioxazafen 2%

[0027] Iprodione 10%

[0028] Dimethylformamide 15%

[0029] Octylphenol ethoxylate 3%

[0030] Attapulgite particles make up to 100%

[0031] The preparation method of the granules is as follows: adopt the adsorption granulation method, dissolve Tioxazafen and iprodione in dimethylformamide according to the above formula, add an emulsifier and mix evenly to make a mixed solution, and prepare the above-mentioned mixture in a mixer. The good mixed liquid is evenly sprayed into the attapulgite granules, and is stirred while spraying for adsorption granulation, and finally dried and sieved to obtain the Tioxazafen and iprodione granules of the present invention.

Abstract

The present invention relates to a novel nematode killing composition, wherein the active components of the novel nematode killing composition comprise tioxazafen and iprodione, and a weight of tioxazafen to iprodione is 1:30-30:1. According to the present invention, the novel nematode killing composition provides significant synergistic effect on the prevention and control of meloidogyne diseases of a variety of crops within the compounding range of the active components, is suitable for prevention and control of wheat meloidogyne, cyst nematode, citrus meloidogyne, cucumber meloidogyne, tomato meloidogyne, hot pepper meloidogyne, peanut meloidogyne, soybean cyst nematode and other nematodes, and has characteristics of good prevention and control effect, long lasting effect, and easy promotion and application.

Description

technical field [0001] The invention relates to a nematicidal composition comprising iprodione and tioxazafen and an application thereof for preventing and controlling root-knot nematode of crops. The combination of the two can achieve a synergistic technical effect. 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 ...
