摘要
１９９２～１９９４年在田间小区试验比较两个拮抗细菌（Ｂ－９１６、Ｐ－９１）和井岗霉素对水稻纹枯病的防治效果。１９９４～１９９５年在江苏省３个基点上进行了Ｂ－９１６防治纹枯病的大面积示范试验。Ｂ－９１６发酵液在田间对水稻纹枯病的为害有较强的控制能力，发酵含菌量为２．５４×１０１１～２．５４×１０１２ｃｆｕ／ｍＬ时，用量３．７５Ｌ／ｈｍ２的防治效果为５０．０％～８１．０％。
Two isolates i.e. Pseudomonas putida type B1 strain P 91 and Bacillus subtilis strain B 916 were compared with Jinggangmycin in their ability to control rice sheath blight at field plots during 1992 1994. Performance test of B 916 of biocontrol on sheath blight was carried out during 1994 1995 at three sites. Results showed that ferment product of B 916 possessed a good control effect of 50.0% 81.1% against rice sheath blight infection under field conditions.
