Problems solved by technology

[0007] In view of the long-term frequent and single use of thiazophos in the control of root-knot nematodes, nematode resistance has increased, and the dosage has increased but the efficacy has decreased. It is necessary to delay the resistance of root-knot nematodes and prolong thiazole. Phosphine life cycle
[0008] At present, there is no relevant report on the nematode control agents with thiazophosphine and methyl jasmonate as active ingredients

Abstract

The invention relates to nematicide containing methyl jasmonate and fosthiazate. The nematicide is prepared from effective components including the fosthiazate and the methyl jasmonate, wherein the weight ratio of the fosthiazate to the methyl jasmonate is (1 to 20) to 1. The nematicide provided by the invention has a synergistic interaction effect and can be used for effectively preventing and controlling root-knot nematode diseases; the pesticide cost and the dosage of chemical pesticide are easy to reduce, the resistance of the root-knot nematode diseases is relayed and the life cycle of the fosthiazate is prolonged.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a nematicide containing methyl jasmonate and thiazophos. Background technique [0002] Meloidogyne incognita is one of the main nematodes that parasitize plants in my country. With the development of agricultural production and rural economy in China, the planting area and multiple cropping index of vegetables in protected areas are increasing continuously. It makes crop rotation and stubble fall difficult, and root-knot nematode damage is becoming more and more serious. [0003] The harm of root-knot nematodes is mainly manifested in two aspects. One is that the larvae invade from the root tip meristem of the plant. After the invasion, the esophagus secretes and forms an enzyme and plant hormone, which stimulates the division of host cells to form giant cells, and then forms Root knots cause great damage to the root conduction system, affecting the normal transportation of w...
