Effect of irrigation methods and polyethylene mulches on disease severity of Phytophthora root rot on chili peppers caused by Phytophthora capsici
Phytopathology 86 (11 suppl.), S62-S62
Abstract: A field experiment is being conducted to study the effects of three irrigation methods (alternate row furrow, subsurface drip daily and every three days) and three different colored polyethylene mulches (black, silver on black and white on black) on the disease severity of Phytophthora root rot on chile peppers (Capsicum annuum) caused by Phytophthora capsici. Higher disease severity was observed in beds which were furrow irrigated. Also plants grown on the white on black mulch had higher disease severity than those grown on the other mulch treatments. Drip irrigation was shown to significantly increase green and red Chile marketable yields regardless of P. capsici infestation when compared to alternate row furrow irrigation. Higher green and red chile marketable yields were observed from plants grown on the mulched beds when compared to plants grown in non-mulched beds regardless of P. capsici infestation. Red chile marketable yields were higher in plants grown on black or silver on black mulches when compared to plants grown on the white on black mulch.
