Evaluation of fungicides and bioagents against Fusarium proliferatum under In vitro by spore germination inhibition technique

Bottle gourd is a cucurbitaceous vegetable of culinary and medicinal importance cultivated in various tropical and subtropical regions of world. This crop is exposed to a wide variety of seed and soil mycoflora, out of which Fusarium proliferatum is utmost important as far as seed germination, viability and seedling vigour are concerned.

Study was taken up to evaluate different fungicides and bioagents for their efficacy against the fungus Fusarium proliferatum under in vitro through spore germination inhibition technique.

Spore germination inhibition of 86.00%, 85.00% and 81.33% was recorded with hexaconazole (5% SC) @ 0.2% (C₃), mancozeb (75% WP) @ 0.3% (C₃) and Pseudomonas fluorescens (1% WP) @ 2% (C₃), respectively. The inhibition in spore germination by mancozeb (75% WP) and Pseudomonas fluorescens (1% WP) was upto 77.33% and it was 61.78% and 67.33% in treatments involving carbendazim (50% WP) and Trichoderma harzianum (1% WP) that could be exploited to devise integrated approach for disease management.
