Sustainable crop production is compulsory to make sure global food security and environmental safety. Synthetic chemicals (herbicides) exposure is at high risk in developing countries like Pakistan where there is no awareness about the safe use of agro-chemicals. For controlling weeds (self grown plants) the application of synthetic chemicals leads to many environmental problems like chemical resistance and health hazards concerns. Thus, bioherbicides (plant natural compounds) seems to be an eco-friendly approach for weed suppression. Weed infestation is inevitable and thus farmers are always concerned about weed control techniques. So for avoiding the deterioration impacts of chemicals we conducted a field experiment to test the bioherbicides of different plants including sorghum, sunflower, Parthenium, Common reed, Johnsongrass and Rice straw to control the weeds/ self grown plants in wheat crop. The results of the instant study revealed that all the tested plants in general and common reed and sunflower in particular showed encouraged results for controlling weeds in wheat crop. Both the common reed and sunflower plants gave 68 and 65% weed control respectively, and leading to 35 % increase in yield of wheat. Moreover, the application of bioherbicides not only decreased the fresh and dry biomass of weeds, but also showed no phytotoxic effects on wheat crop. The plants under the study are easily available and could be efficiently used for weed management in different crops. However, the proper training and popularization of the concept of bioherbicides among the farming community can greatly accelerate the success of bioherbicides.
