Problems solved by technology

The nematode invades the root tissue of the plant and develops in the tissue. The larvae continuously absorb the nutrients of the plant, so that the nutrition cannot be delivered to all parts of the plant normally. less, resulting in reduced production
Due to the large number of wounds caused by nematode infestation, pathogenic fungi and bacteria are easy to invade, often causing root disease complex and aggravating the damage

Abstract

The invention discloses a ternary sterilizing and nematode killing composite with a synergistic effect, and relates to the technical field of pesticides. The ternary sterilizing and nematode killing composite is prepared from the active ingredients of fluopyram, abamectin and derivatives thereof, and triazole fungicide; the fluopyram, the abamectin and the derivatives thereof, and the triazole fungicide are in the mass ratio of 1:0.01-30:0.01-40. According to the ternary sterilizing and nematode killing composite, the fluopyram, the abamectin and derivatives thereof, and the triazole fungicide are compounded as the active ingredients; the ternary sterilizing and nematode killing composite has an obvious synergistic effect on fungi and various nematodes; the field pesticide using amount can be greatly reduced; environmental pollution and pesticide residues are effectively reduced; the cost is reduced. The action mechanisms of the fluopyram, the abamectin and the derivatives thereof, and the triazole fungicide are different, the production of pesticide resistance can be delayed, the lasting period is long, and the pesticide using frequency is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a ternary bactericidal and nematocide composition with synergistic effect. Background technique [0002] Soil-borne diseases and nematodes are serious hazards in vegetable cultivation, and the disease is getting worse year by year. The nematode invades the root tissue of the plant and develops in the tissue. The larvae continuously absorb the nutrients of the plant, so that the nutrition cannot be delivered to all parts of the plant normally. less, resulting in reduced production. Because nematode infestation causes a large number of wounds, pathogenic fungi and bacteria are easy to invade, often causing root disease complex and aggravating the damage. Therefore, the control of plant root diseases and nematodes should be carried out at the same time. [0003] In addition, due to the difficulty in the development of new high-active ingredients, the application and economic d...
