Effect of consortium of Trichoderma harzianum isolates on growth attributes and Sclerotinia sclerotiorum rot of brinjal

Abstract

An experiment was conducted in the year 2008-09 and 2009-10 and evaluated the effect of individual and consortium of Trichoderma harzianum isolates BHU-51 and BHU-105 challenged with Sclerotinia sclerotiorum on growth attributes of plants and their biocontrol potential against Sclerotinia sclerotiorum rot of brinjal. The Trichoderma treated plants showed greater growth and vigor of the plants than untreated pathogen inoculated control. In the field trial shoot length, chlorophyll content and yield were recorded maximum in consortium treated seedlings and followed by individual Trichoderma treated seedlings whereas the lowest was recorded in untreated pathogen inoculated control. Mean Disease Rating (MDR) was recorded maximum in the control whereas the minimum was observed in the consortium treated seedlings. The maximum Percent Disease Reduction (PDR) was also recorded in the seedlings treated with consortium
