摘要:

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。

Abstract:

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.

Key words: Trichoderma water dispersible granules, field efficacy experiment, biological control, Rhizotonia cerealis
