Abstract :This study examined the effects of arbuscular mycorrhizal fungi insert ignore into journalissuearticles values(AMF);, humic acid insert ignore into journalissuearticles values(HA);, and whey insert ignore into journalissuearticles values(W); application on wilt disease caused by Verticillium dahliae Kleb. in tomato, pepper, and eggplant. Single, dual, and triple applications of AMF insert ignore into journalissuearticles values(2.5 g inocula of either Glomus mosseae or G. intraradices);, HA insert ignore into journalissuearticles values(500 ppm);, and W insert ignore into journalissuearticles values(50 mL kg-1); were found to improve the morphological growth and nutritional status of all three host species. Moreover, dual and triple applications reduced the severity of wilt disease caused by V. dahliae by between 40% and 70.5%. Triple application of AMF, HA, and W decreased the number of V. dahliae microsclerotia by 50%. Furthermore, W and HA application promoted AMF growth, with HA application resulting in significantly higher levels of AMF colonization and spore density when compared to untreated controls.
