Abstract
Research work was conducted for the evaluation of effective integrated control measures against Root rot of chilli caused by Sclerotium rolfsii. Preliminary screenings were conducted to select virulent isolate of Sclerotium rolfsii. Effective isolates of Trichoderma harzianum, Chaetomium globosum, fungicides and plant extract were screend out against S. rolfsii. A total of 10 isolates of each Trichoderma harzianum and Chaetomium globosum were screened following dual plate technique on PDA against S. rolfsii. Three different concentrations of four fungicides (Aimcozim, Dithane M-45, Rovral 50 WP and Vitavax-200) and four plant extracts neem (Azadirachta indica), onion (Allium cepa) ginger (Zingiber officinale) and garlic (Allium sativum) were evaluated against the mycelial growth of S. rolfsii on PDA. Two separate set of experiments were conducted by inoculating the soil with S. rolfsii and then treated with the six compatible treatment combination sets namely Trichoderma+garlic+Vitavax (T3), Trichoderma+garlic (T4), Trichoderma+Vitavax (T5), Chaetomium+garlic+ Vitavax (T6), Chaetomium+garlic (T7), Chaetomium+Vitavax (T8) and Trichoderma+ Chaetomium + garlic+Vitavax (T9) along with two control sets (T1 and T2) for evaluation. The growth of S. rolfsii was inhibited by the separate application of T. harzianum isolate (Th1), Chaetomium globosum isolate (Cg5), Vitavax-200 and garlic extract, significantly, in compare with all other individual control measures. Significantly effective control of root rot of chilli was observed when both soil was inoculated with S. rolfsii treated with T. harzianum (Th1), C. globosum (Cg5), Vitavax-200 at 400 ppm and garlic extract at 5% combindly (T9) in comparison to any other intgegrated combinations and individual measure. Application of individual components of the above treatment combination (T9) was also significantly effective over all other measures to minimize root rot of chilli. However, efficacy of the measures was much improved when they are applied in integrated approach.
