Abstract:
Taking walnut trees as materials,Chromaphis juglandicola Kaltenbach as control object,using spraying method,the control efficacy of 3 kinds of biological agents on Chromaphis juglandicola Kaltenbach was studied comparing with 2 kinds of chemical agents.The results showed that 20% imidacloprid SL,30% acephate EC and 44% chlorpyrifos EC had quick and good control effect.5 days after treatment,except 0.3% azadirachtin EC,the control effect of another 4 kinds of agents were more than 98%,there was no significant difference.7 days after treatment,the control effect of 0.3% azadirachtin EC was 90.12%,0.5% matrine EC was 98.91%,20% imidacloprid SL was 99.37%,30% acephate EC and 44% chlorpyrifos EC control efficiency reached 100%.In summary,0.5% matrine EC and 20% imidacloprid SL control effect were good and safe for the walnut trees,could be extended in the production practice.
