Weeds are the notorious plants which cause considerable damage with devastating effects on the agricultural sector of agro based economy of Pakistan. The study under consideration is well direct at studying effects of weedicides on weed and they produce adaptation against them. One of the most detrimental weed in Pakistan is Coronopus didymus which is our topic of concern in this study. Different herbicides were sprayed post emergent to study the morphological and physiological adaptive components of this species. Based on the result from experimentations it was concluded that this plant showed less resistance against weedicides. Coropus didymus showed significant increase in physiological parameter i.e. photosynthetic pigmentation and mineral uptake against Sulphosulfuran and Novex, while Trump and Bromoxynil caused reduction in morphological parameter. Instead of separate application of specific herbicide a mixture of two or more two herbicides produces and fruitful result.
