【摘要】 <正> 防治水稻白叶枯病,目前虽有一套行之有效的综合防治措施,但由于对病原细菌侵染规律摸得不透,因而在措施上环环都要抓,手续繁琐,急需进一步提高。目前检测水稻白叶枯病菌常用的方法主要有分离培养,噬菌体法、镜检观察喷菌法、浓缩接种法等数种,均有一定的缺点。如分离培养法容易污染,而且标样一经干燥即不易检出;噬菌体更多还原

【Abstract】 A reverse indirect hemagglutination test (RIHT) used in the detection of bacterial leaf blight pathogen in leaves and stubbles of infected rice was sensitive, specific and rapid. The Xanthomonas oryzae may be differentiated from X. panici, X. oryxicola, pseudomonas oryzicola and other bacterial contamination within two hours. The RIHT was superior to the bacterial stream observation under microscope and the reaction of bacteriophage examination and was completely identical to the result of the inoculation of rice.更多还原
