EFFECT OF GY LEAF SPOT ON OIL CONTENT OF RAPESEED AND MUSTARD

Short Communication

Abstract

Grey leaf spot (GLS) is an economically important fungal
disease of rapeseed and mustard in many parts of the world.
Alternaria brassicae (Berk.) sacc. the causal agent of GLS is
a necrotrophic pathogen and can produce conspicuous
spotting of all aerial plant parts depending on the host reaction
and environmental conditions (Kolte 1985 and Conn
et al 1990). There are conflicting reports on the effect of
A.brassicae on the oil content of Bras sica spp. seeds (Stovold
et al1987 and Seidle et aI1995). The present study was therefore
undertaken to examine this conflicting and unaddressed
problems of rapeseed and mustard in Pakistan due to severe
edible oil crises in the country.
