摘  要:
[目的]检测粉红粘帚霉67-1防治水稻纹枯病的田间效果。[方法]以井冈霉素为对照,设置450、600、750、900和1 050 g/hm25个浓度的孢子粉喷施感染纹枯病的水稻,定期考察病情指数,结合测产结果分析粉红粘帚霉对水稻纹枯病的防治效果。[结果]2亿活孢子/g粘帚霉孢子粉剂1 050 g/hm2处理抗病保产效果最为显著,防效为68.51%,超过5%井冈霉素水剂3 L/hm2对照的防治效果;该处理的增产效果也较明显,比清水对照组增产9.63%,比5%井冈霉素水剂3 L/hm2对照增产2.96%。[结论]该研究可为粉红粘帚霉67-1的大面积推广使用提供依据。

摘  要:
[Objective] To detect field effects of Gliocladium roseum 67-1 against rice sheath blight. [Method]450,600,750,900 and 1 050 g/hm2spore were used on rice infected with sheath blight,the control effect was observed. [Result] The biocontrol effects of 2 × 108 spore per gram Gliocladium wettable powder 1 050 g/hm2treatment showed significant resistance and maintain production effects,and the control effects was 68. 51%,which was higher than 5% Jinggangmycin 3 L/hm2treatment. Additionally,1 050 g/hm2treatment displayed obviously effects on increasing crop productions,productions of 1 050 g/hm2treatment were higher 9. 63% than CK1,and were higher 2. 96% than Jinggangmycin 3 L/hm2. [Conclusion] The study can provide basis for large area utilization of Gliocladium roseum 67-1.
