Evaluation of microbial consortia against Okra root rot [Macrophomina phaseolina (Tassi) Goid.]

Abstract

Okra [Abelmoschus esculentus (L.) Moench] is the only vegetable crop of significance in the Malvaceae family and is very popular in the Indo-Pak subcontinent. In India, it ranks first in its consumption. The crop was found to suffer from stem and root rot disease in
severe form in many region of Gujarat state during Kharif, 2021. So for its management different biocontrol agents evaluated under field condition, recorded minimum disease incidence 17.88 % was recorded in T. viride @ 2.5 kg/ha + P. fluorescens @ 2.5 kg/ha + 300 kg FYM which was found at par with T. harzianum @ 2.5 kg/ha + P. fluorescens @ 2.5 kg/ha + 300 kg FYM with 22.07 per cent disease incidence and the highest yield (100.99 q/ha) was obtained in T. viride @ 2.5 kg/ha + P. fluorescens @ 2.5 kg/ha + 300 kg FYM, which was statically at par with T. harzianum @ 2.5 kg/ha + P. fluorescens @ 2.5 kg/ha + 300 kg FYM (94.65 q/ha).
