Abstract
Aims: To determine the efficacy of chemicals/bioagents against foliar diseases of mungbean.
Study Design: Randomized Block Design (Field experiments)
Place and Duration of the Study: Field experiments were conducted at Agricultural Research Station, Mandor, Jodhpur during the Kharif 2022 & Kharif 2023
Methodology: Different novel fungicides/bioagents were applied against foliar diseases of mungbean. Ten treatments viz; soil application with Trichoderma harzianum @ 5kg/ha enriched in 100 kg of FYM., seed treatment with Trichoderma harzianum @ 10g/kg seed, foliar spray of Trichoderma harzianum @ 2g/l, foliar spray of carbendazim 50% WP @ 0.1%, foliar spray of difenoconazole 25 EC @ 0.1 %, foliar spray of tebuconazole 250 EC @ 0.1%, foliar spray of tebuconazole 50% + trifloxystrobin 25% WG @ 0.1%, foliar spray of pyraclostrobin 133g/l+ epoxiconazole 50 g/l w/w SE @ 0.15%, foliar spray of azoxystrobin 18.2 % + difenoconazole 11.4 % SC @ 0.1%, and control (untreated) were taken in study. The diseases assessment was done after 10 days of spraying and percent disease incidence was calculated.
Results: Foliar spray of tebuconazole 50% + trifloxystrobin 25% WG @ 0.1% was most effective in reducing the anthracnose PDI (19.41%) and cercospora leaf spot (18.26%) followed by foliar spray of azoxystrobin 18.2 % + difenoconazole 11.4 % SC @ 0.1% (24.36 and 21.05 %).
Conclusion: Among all the tested treatments, foliar spray of tebuconazole 50% + trifloxystrobin 25% WG @ 0.1% was most effective followed by foliar spray of azoxystrobin 18.2 % + difenoconazole 11.4 % SC @ 0.1% in managing both the diseases.
