Abstract

The invention relates to the technical field of anti-photolysis agricultural bactericides, relates to the technical field of A01P3 / 00IPC, and in particular relates to an anti-photolysis suspending agent and a preparation method thereof. The bactericidal composition is prepared from the following raw materials in percentage by mass: a) 1-99 wt% of active ingredients, wherein the active ingredients comprise boscalid and fludioxonil; b) 0-5 wt% of a dispersant; c) 0-4 wt% of a wetting agent; d) 0-7wt% of a functional auxiliary agent, except 0, the functional auxiliary agent is an anti-photolysis auxiliary agent; e) 0-10 wt% of other auxiliary agents; f) 0 to 0.8 wt% of a defoaming agent; and g) the balance of soft water. The boscalid-fludioxonil photolysis-resistant suspending agent provided by the invention has excellent light stability and small light degradation rate, can keep long-term stability during use, and can more sufficiently permeate into crops and contact with an inhibited object, thereby achieving better bacteriostatic and bactericidal effects. Moreover, after the boscalid and fludioxonil photolysis-resistant suspending agent is applied for 7 days, 10 days and 15 days, the control effect of the suspending agent obtained by the invention is superior to that of a commercially available product.

Description

technical field [0001] The invention relates to the technical field of anti-photolysis agricultural fungicides, to the technical field of A01P3 / 00IPC, and in particular to a photolysis-resistant suspending agent and a preparation method thereof. Background technique [0002] Fludioxonil is a phenylpyrrole fungicide, which is extracted and isolated from the antibiotic pyrrole nitro. The main metabolite of fludioxonil is formed under light conditions, and photodegradation is the main factor affecting the degradation pathway and degradation rate of fludioxonil, which has an important impact on the efficacy and environmental risk of fludioxonil. Photodegradation of pesticides refers to the chemical reaction of chemical structure changes of pesticides exposed to the environment under the action of light. Photolysis will have a significant impact on the efficacy, toxicity and residues of pesticides. The photolysis of pesticides includes two types: direct photolysis and indirect p...
