Efficacy of Different Plant Extracts on Fusarium Wilt caused by Fusarium oxysporum in Chillies under Field Condition

Abstract

Chilli (Capsicum annum L.) is vegetable crop belongs to family Solanaceae. It is an important source of vitamin A and C. In developing countries most of chilli diseases are due to fungal attack and cause severe losses in yield. Fusarium wilt of chilli which is caused by Fusarium oxysporium f. sp. capsici is an important disease of chilli which causes heavy yield losses in Pakistan. Present research was planned to evaluate effect of different concentrations of plant based phyto-extracts against Fusarium wilt on chilli pathogen under natural field condition. In research trails the leave extract of Euclayptus globulus, Cassia fistula, Moringa oleifera, Vachellia nilotica and Azadirachta indica were evaluated in the management of fusarium wilt. These trails were planned under Randomized Complete Block Design (RCBD). Three concentrations of above mentioned leaf extracts were used 20%, 30% and 40%. At 40% Eucalyptus, Moringa and Azadiracta gave best results with maximum reduction in Fusarium wilt. While all other extracts results were also satisfactory. So we can use these botanicals as a control for this disease in chilli. Keywords: Capsicum annum, Fusarium wilt, Fusarium oxysporium, Phyto-extracts.
