Preparation and method for controlling plant pathogenic nematodes

Abstract

The invention provides a preparation for controlling plant pathogenic nematodes. One or any of trichloroisocyanuric acid, chloroisobromine cyanuric acid and sodium dichloro isocyanurate and one or more of cosolvent, surfactant and filler are mixed to form the preparation. In addition, the invention also discloses a method for controlling plant pathogenic nematodes, in which the compound or the preparation is diluted in water and then irrigated to the roots of crops suffering from nematodes or sprinkled in soil to kill nematodes. The invention can effectively control the harm of nematodes, and can replace the usage of high-toxicity pesticides or reduce the usage of pesticides to the max, so that the harm of pesticide residue on the human being and livestock and environment pollution can be reduced. The preparation is highly effective, low in toxicity, green and environment-friendly, and is easy and convenient to operate and easy to popularize and use.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an environment-friendly, high-efficiency, low-toxicity and no-residue pesticide preparation and a method for killing nematodes. Background technique [0002] Plant nematodes have the potential to parasitize all parts of a plant, including plant roots, flower buds, leaves, and stems. Nematodes are estimated to cause $3.2 billion in global economic losses in soybeans and millions of dollars in turfgrass losses annually, according to It is roughly estimated that the annual economic loss of major crops in the world due to nematode damage can reach about 12%. [0003] Among the parasitic plant nematodes, root-knot nematode (Meloidogyne spp.) is an important class of plant pathogens that parasitize the roots of crops and seriously endanger the world's agricultural production. There are more than 3,000 species of host plants belonging to 114 families, including rice, peanuts, tobacco, tea, fr...

AI Technical Summary

Problems solved by technology

At present, the domestic pesticides used to prevent and control nematodes are mainly abamectin emulsifiable concentrate, which contains up to 85% xylene and is used in a large amount. The actual use is generally 2000-3000 milliliters per mu, which is quite serious for environmental pollution. The production of new EC pesticides has been banned, and the development of new high-efficiency, low-toxicity, and environmentally friendly nematode control preparations has become one of the urgent problems to be solved in current agricultural production.
