Abstract

Effect of hill bunt disease on photosynthesis and yield in wheat and efficacy of some plant extracts for its control.

Abstract

A field experiment conducted during rabi 1998/99 and 1999/2000, in Uttaranchal, India, showed that hill bunt or stinking smut (caused by Tilletia foetida [T. laevis]) reduced total dry matter, test weight, harvest index and grain yield of wheat cv. Girija. Hill bunt infection also reduced flag leaf photosynthesis, transpiration and stomatal conductance. Seed treatment with Oxalis and Cannabis leaf extracts significantly controlled hill bunt incidence, resulting in significant increases in yield and photosynthetic parameters studied.
