摘要
[目的]筛选出核桃黑斑病有效的防治药剂。[方法]依据核桃黑斑病叶部发病特征设立核桃黑斑病的叶片病情分级标准,研究6种不同类型药剂对核桃黑斑病的田间防效及对核桃的增产效果。[结果]6种药剂对核桃黑斑病均有一定的防治效果,产量随着防治效果的提高而明显增加,其中效果最好的为15%络氨铜水剂,其防效为78.35%,增产幅度达73.90%。[结论]试验结果为核桃黑斑病防治和科学用药提供了理论依据。
[ Objective] To screen out effective chemicals for controlling walnut black spot. [ Method] We established the grading standard of leaf for walnut black spot according to leaf occurrence characteristics and symptom, and studied the field controlling effect of six different fungi- cides against walnut black spot as well as the yield increasing role. [ Result ] All the fungicides had certain controlling effects to walnut black spot, and the effect of yield increasing was observably increased with the improvement of controlling effect. The best one was 15 % Cuaminosulfate AS with 78.35% of controlling effect and the yield increasing rate was 73.90%. [ Conclusion] The results provide theoretical basis for the con- trol of walnut black spot and scientific application.
