MANAGING FUSARIUM WILT OF PEA BY UTILIZING DIFFERENT APPLICATION METHODS OF FUNGICIDES

Abstract

Fusarium wilt of pea is an ubiquitous disease of pea in all peas growing areas. The disease is able to cause hundred percent yield losses under favorable conditions. Multiple management approaches are in use to control this soil pathogen on different growth stages of crop, in which chemical control is providing quick response. This study was designed to evaluate different fungicides and their application methods to inhibit the pathogenic growth and development. Moreover, minimum effective concentration of fungicides against wilt disease of pea was also evaluated. Both in vitro and in vivo bio assays were designed to test the fungicidal efficacy. During in vitro assay minimum effective concentration of 10ppm from four fungicides Thiophanate methyl, Acrobat, Matalyxal and Fosetyl aluminium was evaluated. In green house assay flooding method was proved more affective against wilt disease of pea. The fungicides application showed significantly lower disease incidence as compared to untreated control. Acrobate provided more appreciable response to decrease disease incidence during flooding method and Fosetyl aluminum showed good efficiency in inhibition of pathogen during seed treatment and spraying method. Plant growth parameters were also measured and significant improvement was observed in growth response of treated plants as compared to untreated control. The results showed that fungicides can provide efficient control measures against pea wilt disease by utilizing appropriate application method.
