Efficacy of different inoculation techniques for Rhizoetonia root rot in cotton

摘要

Among the three inoculation techniques for Rhizoctonia root rot tested during kharif 2003 and 2004 under artifical conditions of inoculation, soil application technique gave the maximum plant mortality (85.8% and 89.3%) in varieties F 846 and RG 8, respectively. Soil application technique of Rhizoctonia solani and R. bataticola was the most efficient method of artificial inoculation of the pathogens for its further mass multiplication, meant for using inoculum of these fungi on a large scale in the field, to induce maximum disease under artificial condition of inoculation.
