A brief note on the incidence and management of Plasmodiophora rassica

Abstract

Plasmodiophora brassica is a causal agent of brassica clubroot, and synthetic and bio fungicides showed actions against P. brassica. Under controlled-environment conditions, the mechanism of suppression of P. brassica by bio fungicides was antibiosis and mediated host resistance. To promote the delivery of bio fungicides, various formulations like granular and seed treatment were produced, so neither bio fungicides nor chemical fungicides were sufficiently compelling to reduce the population of resting spore P. brassica. Resistant cultivars substantially decreased clubroot intensity and canola yield losses. P. brassica resistance is the most consistent and economically appropriate management approach, but some studies indicate that clubroot resistance may not be robust. To build and deploy a different source of resistance constantly. The bait plants and soil modifications are not commercially practical. Crop data manipulation, soil fumigation, chemical fungicide application, and bio fungicides have much more ability to control P. brassica. The combinations of strategies that can minimize the pressure of disease in infested areas and enhance the resilience and number of the resistant gene versus P. brassica still need to be identified.
