Pesticide composition as well as preparation method and application thereof

Abstract

The invention discloses a pesticide composition as well as a preparation method and application thereof. The pesticide composition comprises the following particular constituents in percentage by weight: 1%-90% of effective constituents and 10%-99% of a pesticide carrier, wherein the effective constituents are JS399-19 and fluensulfone, and the weight ratio of JS399-19 to fluensulfone is (1-60):(60-1). The synergistic effect of mixing of JS399-19 and fluensulfone is utilized for making up the own insufficiencies of a single-dose pesticide, the drug resistance of plant diseases and insect pests is avoided, the medicament application effect is improved, the bactericidal spectrum is enlarged, the toxicity is lower, and the economic benefits and environment-friendly benefits are obvious. Lots of experiments prove that after combination of JS399-19 and fluensulfone according to the weight ratio, the control effects on all of the rice bakanae disease, the aphelenchoides besseyi, the vegetable fusarium wilt, the nematodosis and the like are remarkable.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a pesticide composition for preventing and treating fungal diseases and nematode diseases of rice, vegetables, fruit trees or other economic crops, a preparation method and application thereof. Background technique [0002] Drugs are the main factor causing drug resistance in pathogenic bacteria. First of all, this is related to the characteristics of the active ingredients of the fungicide. Under normal circumstances, pathogenic bacteria are prone to develop resistance to selective and highly effective systemic fungicides, especially those acting on genetic factors. Because this type of fungicide has a single action site, the gene mutation of the action site of the target pathogen can easily lead to a change in affinity with the fungicide. Second, it is closely related to the selection pressure of the agent. In the process of interaction between pathogenic bacteria and fungi...

AI Technical Summary

Problems solved by technology

However, as mentioned above, long-term use of cyprostrobin will produce certain resistance of pathogenic bacteria, so it cannot achieve a good long-term control purpose

In order to achieve a 100% control effect, farmers generally use excessive pesticides in the actual use process. As can be seen from the above, excessive use further increases the probability of pathogenic bacteria developing drug resistance. Increasing the cost of planting crops will bring harm to the land, cause environmental pollution, destroy the ecological balance, and further affect the sustainable development of agriculture
