Abstract
Cabbage is one of the common Cole crop which is widely grown throughout India. It is affected various disease including, Alternaria leaf spot, black rot, club root, downy mildew and powdery mildew. Alternaria leaf spot, caused by Alternaria species such as A. brassicae and A. brassicicola, has been documented on every continent and is a prevalent disease affecting cabbage. Among the various diseases impacting cabbage, it stands out as a major contributor to yield loss, averaging between 32-57%. An experiment Effects of bio-inoculation on the growth of cabbage seedlings, as well as the disease progression of Alternaria leaf spot under challenge inoculation was conducted at Department of Plant Pathology, Rama University, Kanpur during 2023. Result of the study revealed that. application of Trichoderma as a seed treatment led to higher root and shoot dry biomass (0.080 and 0.021 mg/ seedling respectively), higher % increase in root and shoot dry weight (61.25and 82.78%) was found in T1 (Seed treatment with trichoderma harzianum) whereas highest root: shoot ratio (0.222) was reported in treatment T2.
