Seed-dressing agent

Abstract

The invention relates to a seed-dressing agent containing fludioxonil. The seed-dressing agent is characterized in that effective components in the seed-dressing agent include the fludioxonil (A) and at least one of naphthoxyacetic acid and gibberellic acid (B), wherein the weight part ratio of the effective components (A to B) is 40:1 to 0.1:40 and can be 20:1 to 0.1:10 preferably; the total weight part of the effective components (A and B) in a preparation of the seed-dressing agent accounts for 1-80 percent of the total weight part of the whole preparation and accounts for 1-25 percent preferably. A pesticide preparation formulation which can be prepared from the seed-dressing agent is a suspended seed coating, an emulsifiable concentrate, wettable powder and granules. The seed-dressing agent has a remarkable synergistic effect, the problem of weak sterilization performance of the naphthoxyacetic acid and the gibberellic acid is solved, the problem of gradual reduction of the sterilization effect of the fludioxonil is solved, the sterilization stability of the fludioxonil under the external environments of different temperatures, different degrees of dryness, different degrees of humidity and the like is improved, and the drug resistance is delayed.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a seed dressing agent containing fludioxonil. Background technique [0002] Fludioxoni has a unique mechanism of action. It inhibits the transfer related to glucose phosphorylation and inhibits the growth of fungal mycelia, eventually leading to the death of the pathogen. It has no cross-resistance with existing fungicides. Its chemical name is: 4-(2,2-difluoro-1,3-benzodioxolan-4-yl)pyrrole-3-carbonitrile, which is a non-systemic broad-spectrum fungicide. As a foliar fungicide, it is used to prevent and control Fusarium nivale, Tilletia tritici, and R. blight, etc. It has special effects on Botrytis cinerea; as a seed treatment agent: it is mainly used to prevent and control species in grains and chives. Inherited and soil-borne pathogens such as Alternaria, Ascospora, Aspergillus, Fusarium debris, Helminthiasis debris, Rhizoctonia and Penicillium bacteria. [00...

AI Technical Summary

Problems solved by technology

[0007] Therefore, in order to meet the actual requirements of agricultural production, it is imminent to develop a new type of pesticide seed dressing agent with wide application range, high control effect, low toxicity and environmental protection. A compound screening test was carried out among high-efficiency and environmentally friendly pesticides with different action mechanisms to solve the problem of the decline in the control effect of fludioxonil single agent in actual production. After a large number of experiments, a new fungicidal composition seed dressing agent was finally proposed. Its main active ingredient is at least one of fludioxonil, naphthyloxyacetic acid and gibberellic acid, both of which have good synergistic effect and compatibility, and can well solve the above problems encountered in actual production. It saves time and labor, and the pollution is less compared with other spraying techniques. So far, no seed dressing with at least one of fludioxonil, naphthaleneoxyacetic acid, and gibberellic acid as the active ingredient has been found through preliminary searches.
