EVALUATION OF POST EMERGENCE HERBICIDES FOR WEED CONTROL IN LENTIL (LENS CULINARIS MEDIC)

摘要

Lentil is one of the important rabi pulse crops of India. Heavy infestation of weeds has become a serious problem for increasing and sustaining productivity of lentil. Weeds compete with plants for natural resources during cultivation and reduce the yield of lentil upto 87% (Punia et ah, 2003). The degree of reduction depends upon the density and duration of weed species and fertility status of soil. For weed control in lentil, herbicides like pendimethalin (PE) and fluchloralin (PPI) has been used commercially. There is no herbicide available for use as post-emergence thus, there is necessity of a herbicide which may be used as post-emergence, if a farmer has missed early application. In the north western plain zone of country where Phalaris minoris the major weed in rabi season such a new herbicide has great importance. In cognizance of the above, the present investigation was undertaken.
