Pyrisoxazole-cnidium lactone suspension emulsion and preparation method thereof

Abstract

The invention discloses a pyrisoxazole-cnidium lactone suspension emulsion and a preparation method thereof. The suspension emulsion contains the following components in percentage by weight: 1%-40% of pyrisoxazole, 0.05%-5% of cnidium lactone, 1%-50% of a solvent, 1%-40% of an emulsifying agent, 1%-10% of a dispersant, 2%-4% of a botanical fungicide, 0.1%-10% of a thickener, 1%-5% of an anti-freezing agent, 0.1%-1.0% of an anti-foaming agent, 0.1%-1% of a preservative and the balance being water. The compound preparation can effectively prevent and control diseases and pests of crops (for example, the preparation can simultaneously prevent and control a disease, i.e., blight, and pests, i.e., cotton bollworm, of cotton), and is durable in efficacy. The compound preparation can also effectively prevent and control various diseases on crops, for example the preparation can simultaneously prevent and control white rot, gray mold and powdery mildew on grapes as well as gray mold, leaf mold and powdery mildew on tomatoes; the compound preparation has obvious effects of protecting seedlings and increasing production, is simple in production process, and has labor-saving, time-saving and energy-saving effects, obvious economic, ecological and environmental benefits, and wide development prospect.

Description

technical field [0001] The invention relates to a pyridoxazole-osthole suspension emulsion and a preparation method thereof. Background technique [0002] As people's awareness of environmental protection becomes stronger and more eager for high-efficiency, low-toxicity, low-residue, and environmentally-friendly pesticides, pesticide science and technology workers are working day and night to develop new varieties and new formulations of high-efficiency, low-toxicity, and environmentally friendly pesticides. [0003] Pyridoxazole is a new type of fungicide, which belongs to the class of pyridine oxazolines, and has broad-spectrum and outstanding in vitro bactericidal activity. Botrytis cinerea, leaf mold, early blight, cucumber scab, Fusarium wilt, wheat root rot, head blight, take-all, sheath blight, cotton wilt, grape white rot, brown Leaf spot fungus, peanut brown spot fungus, apple spotted leaf spot fungus, ring spot fungus, corn spot fungus, and head smut have strong i...

AI Technical Summary

Problems solved by technology

Containing a large amount of organic solvents in emulsifiable concentrate, there are unsafe factors such as flammable, explosive and toxic, and it is not conducive to the protection of the environment.

Pyridoxazole is mainly used to prevent gray mold of vegetables, fruit trees and other crops. It also has a certain bactericidal effect on other diseases, but the activity is not high.

The common dosage form of biopesticide osthole is 1% water emulsion, which is mainly used to control powdery mildew of crops, but the control effect on gray mold and downy mildew is poor
