摘要

Powdery mildew disease on pea (Pisum sativum L.) caused by fungus Erysiphe polygoni DC is an important limiting factor in pea cultivation under Punjab conditions. The present field study was undertaken during consecutive two Rabi season of year 2016-17 and 2017-18 to assess the efficacy of pre-mix fungicide tebuconazole + trifloxystrobin (50 + 25) WG (125 + 62.5, 150 + 75, 175 + 87.5 g ai ha~(-1)) in comparison with trifloxystrobin 50 WG @ 87.5 g ai ha~(-1), tebuconazole 250 EC @ 175 g ai ha~(-1) and carbendazim 50 WP @ 125 g ai ha~(-1) against powdery mildew on green peas. Results from two years experiment indicated that foliar applications of tebuconazole + trifloxystrobin (50 + 25) WG @ 175 + 87.5 g ai ha~(-1) at 15 days intervals were highly effective when applied as soon as the first symptoms of the disease appear. The treatment tebuconazole + trifloxystrobin (50 + 25) WG @ 175+87.5 g ai ha~(-1) provided 84.9 and 89.1 disease control and 56.72 and 58.13 q ha~(-1) yield during 2016-17 and 2017-18, respectively.
