RHIZOBACTERIA INFLUENCING RADISH GROWTH A ND BIOLOGICAL-CONTROL OF BLACK ROT AND ANTHRACNOSE

The potential of rhizobacteria to control black rot and anthracnose of radish, caused respectively by Xanthomonas campestris pv. campestris (Xcc) and Colletotrichum gloeosporioides (Cgl). was studied in held co nditions. It was also studied the effect of those rhizobacteria on the growth of seedings, under greenhouse condictions. In the, first and s econd experiments seeds were bacterized, treated with kasugamycin or b enomyl (chemical checks), or untreated. SDR2 and BS isolates were more efficient against Xcc and similar to kasugamycin. JA2 and BS isolates were better against Cgl and similar to benomyl. In relation to germin ation, there was no significant difference among most of the rhizobact eria, fungicides and checks The isolate C21 inhibited the germination sad growth of seedlings with significant difference only for the first parameter. BJ22, JA2 and P2 promoted better seedling growth, however without significant difference for seedling dry weight.
