木霉菌水分散粒剂防治小麦纹枯病的田间药效研究

摘要

In this study,the effect of Trichoderma water dispersible granules (1×108 cfu/g) on the control of wheat sheath blight was tested by field experiment.The results showed that the control effect of Trichoderma seed dressing and root irrigation reached 71.59％ and the increasing yield rate of wheat was 16.8％.Both were obviously higher than that of the control pesticide,20％ Jinggangmycin soluble powder.As a microbial pesticide,Trichoderma water dispersible granules have the advantages of environmental safety,high selectivity,and not easy to induce resistance by pathogen.%通过田间试验,检测木霉菌水分散粒剂(1×108 cfu/g)防治小麦纹枯病的效果.结果表明,木霉菌剂拌种和灌根的防治效果达到71.59％,增产率为16.8％,均明显高于对照药剂20％井冈霉素可溶性粉剂,对环境安全、选择性高且不易产生抗药性.
