Problems solved by technology

Since ultra-low volume liquids are required to have the characteristics of low flammability, high flash point, good solubility to the original drug, low phytotoxicity to crops, and low viscosity, it is difficult for conventional components to meet the corresponding ultra-low volume solvent requirements, so the current Very few ultra-low volume liquids are available
At present, there is no report about the ultra-low volume liquid preparation compounded by morpholines

Abstract

The invention discloses an ultra-low volume liquid containing picoxystrobin and a morpholine bactericide and application thereof, and aims to provide a novel ultra-low volume liquid. The ultra-low volume liquid comprises the picoxystrobin, the morpholine bactericide, an auxiliary agent, a solvent and a cosolvent. The ultra-low volume liquid has the advantages that the effects are achieved quickly, the lasting period is long, the rain wash resistance is achieved, and water and labor are reduced; the ultra-low volume liquid is applicable to ultra-low volume spraying, low volume spraying and electrostatic spraying, can be used for preventing diseases of crops such as paddies, wheat, fruit trees and vegetables, and has better prevention effect on powdery mildew, banded sclerotial blight, rice blast, downy mildew, gray mold, rot, brown rot, root rot and anthracnose, the application range is wide, and the prevention effect is good.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an ultra-low volume liquid containing picoxystrobin and morpholine fungicides and an application thereof. Background technique [0002] Ultra-low-volume liquid formulations are pesticide formulations suitable for ultra-low-volume spraying. Ultra-low volume spray is produced with the appearance of ultra-low volume spray equipment. It is an advanced new technology for pesticide application. Its droplets are oily droplets with uniform fineness, which are easy to adhere to the crops, so the droplets are elegant The loss is small and the utilization efficiency of pesticide is high. Compared with conventional spraying pesticide formulations, it has the following advantages: 1) The spray volume of ultra-low volume liquid is 60-330mL / mu, which is one hundredth of the conventional spray volume, so it has low spray volume and high work efficiency 2) Compared with the conventional droplet diamet...
