Abstract: Use 2%(v/v) avermectins emulsifiable concentrate(EC), 50%(v/v) bamboo tar EC, and 80%(v/v) bamboo tar K+ solubility liquid (SL) to control Phenacoccus kaxinus and Eucryptorrhynchus brandti. We chose Fraxinus chinensis plantation harmed by Phenacoccus kaxinus and Ailanthus altissima Qiantou nursery harmed by Eucryptorrhynchus brandti as sampling fields with five levels and three replications, and 50% phoxim EC as the control. We investigate the control effect after 3, 7, 14 d after spraying respectively. Field experiments showed that the control effect of the three pesticides to Phenacoccus kaxinus all above 65%, and 50% bamboo tar EC is the best pesticide(90.03%) among the three pesticides, which no significant different (P>0.05) compared with the control; The best control effect to the Eucryptorrhynchus brandti was 14 d after spraying, and the efficacy of 2% avermectins EC and 50% bamboo tar EC reached 71.71% and 77.55% respectively, which no significant different(P>0.05) with the control(73.99%). While the efficacy of 80% bamboo tar K+SL was significant lower(P<0.01) than the control. It proved that 50% bamboo tar EC has further application prospect as the pesticide.[Ch, 2 tab. 9 ref.]
