Abstract
Nine kinds of compost extracts were tested primarily for their efficiency, in vitro, against the causal agent of crown gall Agrobacterium tumefaciens (strain C58). The most efficient extracts were then selected and bacteria contained in these extracts were isolated. Twenty-seven isolates bacteria were obtained and investigated in vitro with the objective of selecting efficient antagonists against crown gall disease. The bacterial activity is compared to the reference antagonist Agrobacterium rhizogenes K84 by the double layer method.
