枯草芽孢杆菌C08可湿性粉剂研制及其对番茄早疫病防治效果
Development of a Wettable Powder Formulation of Bacillus subtilis C08 and Its Biocontrol Efficacy Against Tomato Early Blight
摘要
Abstract
Tomato early blight,caused by Alternaria solani,represents a significant disease that severely impacts both the yield and quality of tomatoes,primarily due to its short latent period and rapid reinfection cycle.In contrast to conventional chemical control methods,biological control offers considerable potential due to its environmentally friendly and sustainable attributes.In this study,a strain of Bacillus subtilis,designated as C08,demonstrating strong antagonistic activity against A.solani,was isolated from the rhizosphere soil of healthy tomato plants.The fermentation conditions were optimized,and a wettable powder formulation was subsequently developed using the fermentation broth as the active ingredient.The results indicated that the formulation achieved high efficacy in controlling tomato early blight,significantly promoted plant growth,enhanced the activities of antioxidant enzymes such as superoxide dismutase(SOD)and peroxidase(POD),and improved soil enzyme activities such as sucrase and urease.These findings suggest that strain C08 holds substantial promise as a biocontrol agent for the sustainable management of tomato early blight.关键词
