新农抗诺沃霉素对水稻纹枯病和稻曲病的田间防效

摘要

以井冈霉素、苯甲?丙环唑、戊唑醇不同剂型产品为对照,研究了新的农用抗生素抗诺沃霉素对水稻纹枯病和稻曲病的田间防效.结果表明,5%诺沃霉素WP 1500~3000 g/hm2对水稻纹枯病的防效达81.6%~85.8%,对水稻稻曲病的防效达到39.0%~41.4%,与对照相比增产10.5%~11.8%.%Taking different dosage form products jinggangmycin, difenoconazole?propiconazole,tebuconazole,for comparison, the field control effect of new agricultural antibiotics novonestmycin against rice and rice sheath blight disease were researched. The results showed that the efficacy of novonestmycin 5% WP 1500~3000 g/hm2 could reach 81.6%~85.8% against rice sheath blight and about 39.0%~41.4% against rice false smut. The yield increased by 10.5%~11.8% compared with controls.
