ABSTRACT
Weed infestation is among the main biotic factors affecting growth and yield of
various crops. This issue is more drastic for cereal crops like wheat which is the staple food
crop of over 2.5 billion population of the world. One the control strategies is to investigate
the distribution pattern of weeds under field conditions. In this regard, a survey study was
conducted to investigate the distribution pattern of weed species in wheat crop during 2016-
18 in district Khanewal, Punjab Pakistan. Thirty-six weed species distributed among fifteen
different families were collected from the study area. Family Poaceae was the predominant
with 10 species, while family Asteraceae was the second most dominant family with four
weed species. Cynodon dactylon (L.) Pers. was the most frequently found specie with
frequency value of 79.1% while Paspalum distichum had the highest importance value index
(6.96) among the weeds of the study area. Based on these findings, it is recommended to
create awareness among the farmers about the identified weeds so that weed infestation
could be controlled with the recommended practices.
