<em>In vivo</em> bio-efficacy of fungicide molecules against leaf spot, fruit rot and powdery mildew diseases of Chilli

Abstract

Foliar diseases are causes major qualitative and quantitative yield loss in chilli at both field and storage condition. Management of these foliar diseases through fungicides is much needed effort. Hence, in present investigation different fungicide molecules were evaluated against leaf spot, fruit rot and powdery mildew diseases of chilli. Among fungicides evaluated, Carbendazim 12%+ Mancozeb 63% WP @ 750 g/ha, was found most effective with least leaf spot (9.16 PDI), powdery mildew (18.63 PDI and fruit rot severity (13.45 PDI) compared to other fungicides and untreated control.Maximum fruit yield, 20.37 Q/ha was recorded in treatment Carbendazim 12%+ Mancozeb 63% WP @ 750 g /ha which was significantly superior over rest of the treatments.The cost benefit ratio analysis of different fungicides revealed that, Carbendazim 12%+ Mancozeb 63% WP with dosage 750 g /ha (1:15.1) found to be superior over rest of the treatments.
