Bactericide Screening against Xanthomonas axonop- odis pv. manihotis

The toxicity of 12 kinds of bactericides against the pathogen of cassava bacterial blight （Xanthomonas axonopodis pv. manihotis） was determined by tox- ic medium method. The results showed that 2% triadimefon · 30% ethylicin EC, 80% ethylicin EC, 70% mancozeb WP and 72% strepolin SP had the lowest e...

Summary:The toxicity of 12 kinds of bactericides against the pathogen of cassava bacterial blight （Xanthomonas axonopodis pv. manihotis） was determined by tox- ic medium method. The results showed that 2% triadimefon · 30% ethylicin EC, 80% ethylicin EC, 70% mancozeb WP and 72% strepolin SP had the lowest ef- fective concentration and the best inhibitory effect, while 12.5% myclobutanil SP, 20% thiodiazole-copper SC and 20% bismerthlazol WP had the highest effective concentration but the worst inhibitory effect. Field test of six kinds of bactericides was conducted in Zhanjiang City of Guangdong Province in 2011, and the results showed that 3% zhongshengrnycin WP, 2% triadimefon · 30% ethylicin EC and 80% ethylicin EC had good control effect, which were suggested to be used for field control.
