Problems solved by technology

[0005] The inventor of the present application, on the basis of a large number of experiments, found that the combination of the nematicide tioxazafen and the amino oligosaccharin showed a certain synergistic effect on the prevention and treatment of various root-knot nematodes. After further research, indoor biological On the basis of determination, continue to prepare it into some conventional dosage forms, study its practical application effect in the field, and then complete the present invention, and there is no relevant report about the compounding of the two at present

[0035] 1. Example 1: 6% tioxazafen · amino oligosaccharin granules (1:5)

[0036] Tioxazafen 1%

[0037] Oligoaminosaccharins 5%

[0038] Cornstarch 7%

[0039] White sugar 5%

[0040] Silica 5%

[0041] Kaolin balance

[0042] The preparation method of the granule is as follows: mix tioxazafen, amino oligosaccharin, white carbon black, white granulated sugar, cornstarch and kaolin according to the above formula. After mixing evenly, enter the jet mill for jet milling. Collect the jet-milled powder into a kneader, add 10% water and knead it. After the kneading is completed, enter the extrusion granulator for granulation, and then enter the fluidized bed dryer for drying. Finally, the granules of the present invention are obtained through granulation by a granulator.

Abstract

The invention provides a nematicide composition. The nematicide composition contains the main effective components tioxazafen and amino oligosaccharin at a ratio of 1:30-10:1. In the above ratio rang, obvious synergistic effect of the effective components is achieved, so that using amount of the effective components is reduced, and prevention and treatment effect is improved. The nematicide composition can be prepared into missible oil, particulate agent, emulsion in water, suspending agent, microcapsule suspension, and suspended seed coating agent at will, and is widely used for preventing and treating crop root knot nematode diseases caused by a plurality of pathogen nematodes.

Description

technical field [0001] The present invention relates to a novel nematicide composition and its application, comprising the first active ingredient tioxazafen and the second active ingredient amino-oligosaccharin, the nematicide composition of the present invention shows a synergistic effect on the control of various nematode diseases , especially for the control of crop root-knot nematode disease caused by root-knot nematode incognita. Background technique [0002] Plant parasitic nematodes can infect all parts of plants and cause huge economic losses to agriculture. Plant parasitic nematodes can be classified according to their feeding habits into the following categories: migratory ectoparasites, migratory endoparasites and sedentary endoparasites insect. Mainly include root-knot nematodes, cyst nematodes and resident endoparasites of the genus Heteroderma, which can cause long-term infection in roots. Plant nematodes have a wide range of hosts and often damage melons, so...
