Gannan Normal University successfully developed two new pesticide technicals and corresponding formulations

The Jiangxi Provincial Key Laboratory of Organic Medicinal Chemistry of Gannan Normal University, in collaboration with Ganzhou Wei Pesticide Co.
, Ltd.
, developed two new pesticide original drugs and corresponding formulations for the control of Schistosoma cercariae and Fushou snails
.
Recently, the research group of Professor Fan Xiaolin and Li Xun from the Jiangxi Provincial Key Laboratory of Organic Medicinal Chemistry of Gannan Normal University, in collaboration with Ganzhou Weinong Pesticide Co.
, Ltd.
, has successfully developed two new pesticides for the control of schistosome cercariae and snails after ten years.
The original medicine and corresponding preparations can reduce the frequency of application and reduce pesticide residues and non-point source pollution caused by pesticides
.
Related achievements have been granted invention patents and high-level journals have been accepted for publication
.
At present, Ganzhou Weinong Pesticide Co.
, Ltd.
has applied for the registration certificate of new pesticide technical and preparation to the Pesticide Inspection Institute of Ministry of Agriculture
.
(1) At present, the control of schistosomiasis is mainly to spray high-dose pesticides on a large area to kill the intermediate host Oncomelania.
The amount of pesticides used is extremely large, but the utilization rate is low, the pollution is serious, and the killing effect is not ideal
.
How to improve the utilization rate of pesticides and reduce the amount of pesticides has become a key issue that needs to be solved urgently in the agricultural and environmental fields of China and the world
.
The research team has developed a new type of cercariae for schistosome cercariae, the direct target of schistosomiasis harm to humans
.
At present, the drug is the first in the field of schistosomiasis to adopt a low-volume, low-pollution, low-toxic and environmentally friendly pesticide in the field of schistosomiasis control.
It can quickly kill cercariae and prevent cercariae from invading human skin.
It has a significant protective effect on people exposed to infected water
.
The product is automatically dripped and applied and automatically diffused, which can reduce the frequency of application and is convenient to use, especially suitable for large-area long-distance use
.
The product has been approved and promoted by the majority of schistosomiasis control departments
.
(2) The snail is one of the "most harmful alien invasive species" in China
.
Among the currently popularized control drugs, the compound has a good control effect, but the low temperature use effect is not good, and the environmental pollution is serious and the toxicity is high.
The research team designed a new type of molluscicide molecule, which has low toxicity and good water solubility.
And the advantages of high safety to crops, it makes up for the poor control effect of existing drugs in winter and spring, and the current situation of no effective drug use, and provides a new type of drug for the control of harmful snails
.
At present, field efficacy trials have been carried out in many provinces, and there is no disease on rice and other plants, and the residual amount is one percent of traditional pesticides, which greatly reduces the pesticide residues in rice and other grains
.
