Effects of Biocontrol Strain E26 on Some Ecological Factors

<正> This study was to evaluate the ecological risk of strain E26 (Agrobacterium sp.) by detecting its survival in waters and its effects on rhizosphere microorganisms. The data showed that E26 could not be detected in distilled water, tap water, river water, and rainwater after 36, 36, 8, and 9 days, respectively. E26 did not reveal significant effects on the population of bacteria, fungi, and actinomyces in rhizosphere soil and on the root surface of grapevines.
