Study On Residues And Status Of Organophosphorus And Carbamate Pesticides In Potatoes From Southeast Yunnan Province

Potato is an important food grain under agricultural products,in recent years,due to its increasing the economic benefits of planting,the local government departments as an important growing rich industry to develop,its planting area gradually expanded.In order to understand the region potato organophosphate and carbamate pesticide residues in the status quo,in order to better promote the healthy and stable development of potato industry,this experiment from south gansu longdong region tianshui WuShan County five potato planting towns sampling detection of organophosphate and carbamate pesticides in the potato residue,and the reason for the existence of the analysis,the research on the rules of pesticide residues,put forward the corresponding control countermeasures,for consumer how to prevent excessive pesticide intake when eating potatoes do certain reference,the healthy and stable development of the potato has a certain theoretical and application value.This study in July 2017 to October in tianshui WuShan County HuaLin,TanGe,Yu Pan,ChengGuan,LuoMen,from the city gate five villages and towns of peasant households in potato production use of pesticides investigated in the process,were 50 peasant households,then take 600 samples of potato organophosphate and carbamate pesticide residues in testing,the results showed:(1)the farmers in the process of potato production equipment backward,applying pesticide applying pesticide without scientific phenomenon is extremely common(2)Status of organophosphate and carbamate pesticide residues in the region as a whole is good,the detection rate of 90.7%,the pesticide residue detection rate is 51.7%,the degree of pesticide residue exist significant differences between different villages and towns;(3)Under the same application conditions,there was a difference in pesticide residues among the 8 different varieties tested;(4)The same potato varieties,10 mm in epidermis organophosphate and carbamate pesticide residues in most,from the epidermis to the inside with the increase of depth,the degree of pesticide residue gradually decreases,and pesticide residue levels exist significant differences between different depth;(5)At the same depth of different varieties,there are differences in pesticide residues among some depths,while there is no significant difference in agricultural residues among some depths.In this paper,the application of biological control in potato pest control was put forward.Breeding new varieties of potato with high quality,high yield and disease resistance;The introduction and promotion of high quality potato detoxification and fine new varieties;To establish the specialized prevention and control organization of diseases and insect pests and promote the application of plant protection uav in the prevention and control of potato pests and diseases;To establish the quality and safety monitoring stations for agricultural products in counties and townships,the pesticide residues of potato will be included in the detection and supervision scope,and the monitoring of potato pesticide residues will be increased.Strengthen the supervision of pesticide distribution point;To support a batch of potato detoxification potato enterprises with strong strength and good reputation in gansu longdong south region,and to increase the popularization and application of the stem tip detoxification potato;Improving cultivation and cultivation measures to provide a good agricultural ecological environment for potato growth and development.
