Usage

Description

Pyraclostrobin is a fungicide that belongs to the strobilurin class, which is characterized by its ability to inhibit mitochondrial respiration in fungi. It is effective against a wide range of fungal diseases in various crops, including seed grass and food crops. Pyraclostrobin not only exhibits direct antifungal activity but also has the potential to protect plants by priming them for a boosted activation of subsequently stress-induced defense responses.

Uses

Used in Agricultural Industry:
Pyraclostrobin is used as an agricultural fungicide for the protection of seed grass and food crops against various fungal diseases. It helps in enhancing disease resistance, increasing crop yield, and improving the overall health of the plants.
Used in Enhancing Disease Resistance:
Pyraclostrobin is used as a priming agent to induce rapid accumulation of antimicrobial PR-1 defense proteins in plants after infection with Tobacco mosaic virus and the wildfire pathogen Ps pv. tabaci. This priming effect is associated with enhanced disease resistance in various crops and ornamental plants, both in greenhouse and field conditions.
Used in Increasing Crop Yield:
Treatment with Pyraclostrobin has been shown to increase crop yield in the field. This is due to its ability to induce a 'greening effect,' which refers to the phenomenon of delayed leaf senescence and an increased grain-filling period, resulting in enhanced biomass and yield.
Used in Enhancing Resistance to Abiotic Stresses:
Pyraclostrobin-induced priming is also associated with enhanced resistance to abiotic stresses, such as drought, in the field. This further contributes to the overall health and productivity of the crops.

Preparation method for high-purity pyraclostrobin

The invention relates to the technical field of compound synthesis, in particular to a preparation method for high-purity pyraclostrobin. The pyraclostrobin is synthesized from p-chloroaniline and o-nitrosotoluene as initial raw materials through the steps of diazotizing, cyclizing, oxidizing, bromizing, condensating, reducing, acylating, methylating and the like. According to the preparation method, the problem that the purity of the pyraclostrobin in the prior art is low is solved; and the preparation method for the pyraclostrobin has the advantages of high yield, high purity and high material utilization rate.

IMPROVED PROCESS FOR THE PREPARATION OF PYRACLOSTROBIN

The present invention relates to a novel and improved process for preparation of methyl [2-({[1-(4-chlorophenyl)-1H-pyrazol-3-yl]oxy}methyl)phenyl]methoxycarbamate (Pyraclostrobin)of formula (I) in free form or in agrochemically acceptable salt form useful as a pest control agent starting from methyl [2-({[1-(4-chlorophenyl)-1-H-pyrazol-3-yl]oxy}methyl)phenyl]hydroxycarbamatein simple manner and in high purity and good yield.

Preparation method of high-purity pyraclostrobin

The invention provides a preparation method of high-purity pyraclostrobin.
