Study the Inhibitory Effect of Mustard Seed Powder on the Growth of Sclerotium rolfsii

Stem and Pod rot caused by Sclerotium rolfsii is one of the major constraint affecting the seed and oil production in groundnut growing areas of the world. An attempt was made to manage the disease by holistic approach. In vitro evaluation of different concentrations of mustard was conducted using two types of methods; (a) Continuously exposing to single MSP and (b) fresh MSP was replenished every 24 hours. Cent per cent inhibition of S. rolfsii was observed at 100 and 200 mg of MSP in both the methods. But, 50 mg concentration was also inhibited growth of S. rolfsii up to 93.10% after 72 hours over the control. The test concentrations in this experiment successfully inhibited the growth of S. rolfsii. Hence it is necessary that these treatments be tested under field conditions before they can be exploited in a commercial set up.
