Induced resistance in potato plants against verticillium wilt invoked by chitosan and Acibenzolar-S-methyl
Verticillium wilt of potato is a major limiting factor in potato production caused by Verticillium dahliae. The objective of this study was to evaluate the efficacy two elicitors including Acibenzolar-S-methyl (ASM) and Chitosan as plant activator in controlling of potato verticillium wilt in vitro and greenhouse conditions. ASM and chitosan were tested in vitro using Potato dextrose Agar (PDA)...
متن کاملMechanisms of Action and Dose-Response Relationships Governing Biological Control of Fusarium Wilt of Tomato by Nonpathogenic Fusarium spp.
ABSTRACT Three isolates of nonpathogenic Fusarium spp. (CS-1, CS-20, and Fo47), previously shown to reduce the incidence of Fusarium wilt diseases of multiple crops, were evaluated to determine their mechanisms of action and antagonist-pathogen inoculum density relationships. Competition for nutrients, as represented by a reduction in pathogen saprophytic growth in the presence of the biocontro...
متن کاملInduced resistance in tomato plants by IAA against Fusarium oxysporum lycopersici.
The phytohormone IAA (indol-3-acetic acid) was tested in vitro on growth of tomato wilt pathogen Fusarium oxysporum lycopersici. The hormone reduced spore germination, mycelial dry weight and protein content. Such reduction was matched with the elevation in the hormone concentration. The in vivo application of IAA to soil of the uninoculated plants (controls) improved growth and yielded longer ...
متن کاملEffects of Varying Environmental Conditions on Biological Control of Fusarium Wilt of Tomato by Nonpathogenic Fusarium spp.
ABSTRACT The influence of varying environmental and cropping conditions including temperature, light, soil type, pathogen isolate and race, and cultivar of tomato on biological control of Fusarium wilt of tomato by isolates of nonpathogenic Fusarium oxysporum (CS-20 and CS-24) and F. solani (CS-1) was evaluated in greenhouse and growth chamber experiments. Liquid spore suspensions (10(6)/ml) of...
متن کاملIntegrated management strategies for tomato Fusarium wilt.
Fusarium wilt is caused by the fungal pathogens, Fusarium oxysporum or Fusarium solani. It is a devastating disease that affects many important food and vegetable crops and a major source of loss to farmers worldwide. Initial strategies developed to combat this devastating plant disease include the use of cultural, physical and chemical control. None of these strategies have been able to give t...
