Wheat is the most widely grown cereal grain crop and staple food of
people in the world. Among many other factors of low yield in wheat, one
of the most serious but less addressed causes is the presence of weeds.
Weeds compete with crops for nutrients, light, space, moisture and cause
reduction in wheat vigor, tillering, head size, kernel weight. Weeds
lower the market value of the produce and hence bring economic losses to
the growers. Chemical weed control is preferred over other weed control
methods like manual weeding, mechanical weeding, intercropping, crop
rotation and stale seed bed technique because it is quick, more
effective and relatively cheaper. Grassy (narrow leaved) weeds like
Phalaris minor, Avena fatua, Hordeum vulgare and Cyperus rotandus are
the serious problem in wheat.This book describes identification of
different grassy weeds present in wheat fields and most economical
herbicides for controlling these weeds, especially against P. minor.
