It is defined as the reduction of pest populations by natural enemies and typically involves an active human role. Based on the combination of data in this work, microorganisms, both endophytes and those formulated in commercial products, were identified that can potentially be exploited for the control of grapevine crown gall disease. Biological control is a component of an integrated pest management strategy. vitis, indicating commercial products could be reserves to draw upon to identify useful biocontrol agents.
For the commercial biological control agents, Bacillus subtilis SR63 and Trichoderma asperellum T1 were the most effective strains against A. Two-year in planta trials conducted on rootstocks treated with endophytic isolates showed the effectiveness of two bacterial endophytes, both in the genus Curtobacterium, and one fungal isolate in the genus Acremonium in reducing crown gall development. Experimental trials were conducted to evaluate the effectiveness of treatments based on non-pathogenic endophytes isolated from asymptomatic grapevines growing in vineyards with high incidence of crown gall and on microorganisms isolated from commercial products. 821-833 ISSN: 1386-6141 Subject: Acremonium, Bacillus subtilis, Curtobacterium, Rhizobium vitis, Trichoderma asperellum, Vitis, biological control, biological control agents, crown galls, endophytes, fungi, grapes, pathogens, rootstocks, vineyards Abstract: The current strategies for the control of Agrobacterium vitis crown gall in grape are generally unsuccessful once the pathogen has established in vineyards.
