Effects of Shuidaoqucheng agricultural synergist on the distribution and control of pesticides
[Objective]This study was conducted to clarify the effect of Shuidaoqucheng agricultural synergists on the distribution and field control of pest,so as to guide the scientific use.[Method]The surface tension,static contact angle,atomization and deposition,and the control effect of pesticides on rice diseases and pests after the agricultural synergist being added into the pesticides were studied.[Result]The agricultural synergist could effectively reduce the surface tension and the static inoculation angle,which decreased greatly in the unit time of the pesticides.Moreover,the agricultural synergist could significantly increase the diffusion property and deposition amount of the pesticides on the carrier surface.Results of field application showed that the agricultural synergist could increase the control effect of pesticides on pests and diseases,and the control effect of thifluzamide 240 g/L SC and chlorantraniliprole 200 g/L SC on rice sheath blight and rice leaf roller was increased by 17.41%and 10.23%,respectively.[Conclusion]The Shuedaoqucheng agricultural synergists can effectively improve the distribution of chemical pesticides as well as the control effects of them on diseases and pests in the field.
