To evaluate in vitro efficacy of different fungicides against Pyricularia grisea (Cooke) Sacc. Causing Blast of Pearl Millet [Pennisetum glaucum (L.) R. BR]
Abstract
The study focuses on assessing the efficacy of various fungicides against Pyricularia grisea, the causal agent of blast disease in pearl millet (Pennisetum glaucum). The objective is to identify and characterize fungicides that exhibit potent antifungal activity against P. grisea, offering valuable insights for effective disease management strategies in pearl millet cultivation. The research findings indicated the varied effectiveness of different fungicides in inhibiting mycelial growth in vitro. Propiconazole 25 EC, Difenconazole 25 EC, and Kasugamycin 3 SL displayed the highest effectiveness at concentrations of 1000 ppm and 500 ppm. Hexaconazole 5 EC, Carbendazim 50 WP, and Tridemorph 80EC also exhibited notable inhibition at these concentrations. However, systemic fungicides Benomyl 50 WP and Thiophanate methyl 70 WP showed moderate effectiveness at 1000 ppm, while Tebuconazole 25 EC displayed the least efficacy at both 1000 ppm and 500 ppm in suppressing mycelial growth.

The current study was conducted to detect the pathogenic fungus causing leaf blight disease of guava in Bangladesh, and to evaluate the effect of various physical factors on the fungal growth, in vitro disease management, and the prediction of potential phyto-compounds against the fungus through in silico technique. The fungus was isolated following the tissue planting method, and morphological and…
