Comparative Experiment on the Control of Pinus thunbergii Fiorinia japonica Kuwana With Five Different Combinations of Pesticides and Different Ratios
By comparing 40%Omethoate+480g/L Imidacloprid suspension,45%malathion+480g/L Imidacloprid suspension,45%Chlorpyrifos+5%acetamiprid suspension,4.5%Beta cypermethrin+480g/L Imidacloprid suspension and 50%Dichlorvos EC+5%Acetamiprid EC,the control effect of five kinds of combination agents with different proportions on Pinus thunbergii Fiorinia japonica Kuwana was analyzed.The experimental results showed that 45%Chlorpyrifos EC+5%Acetamiprid EC(3∶2)had the best control effect,followed by 50%Dichlorvos EC+5%Acetamiprid EC(3∶2).The worst is 4.5%Beta cypermethrin+480g/L Imidacloprid suspension(1∶1).
