Abstract: IntroductionC otton (Gossypium hirsutum L.) is a multipurpose crop mainly grown for fiber.It has been cultivated worldwide in more than seventy countries.The first three major cotton producing countries are China, India and USA (Khan et al., 2020).Textile industry is based on raw material provided by the cotton crop.There is a significant gap in average yield and attainable yield potential.It is due to many climatic and agronomic factors (Gwimbi and Mundoga, 2010).Among all other agronomic factors, weeds caused major yield losses to cotton in Pakistan.Weeds are relatively the most competitive, hardy, unwanted, and Abstract | Weeds are a major threat to seed cotton production.Though herbicide offers efficient weed control but it also introduces issues such as the development of herbicide-resistant weeds and environmental pollution which forces experts and farmers to look for better integrated weed management options.Intercultural tillage after pre-emergence herbicides may be used in integration for weed management in cotton crop; however, tillage may reduce the efficacy of pre-emergence herbicides.The present study was conducted to evaluate the impact of tillage (hoeing) on the efficacy of two pre-emergence herbicides (Pendimethalin 330 EC at 825 a i g ha -1 + Acetochlor 50 EC at 1125 ai g ha -1 ) for weed control in cotton under field condition.The results revealed that hoeing 23 days after sowing (DAS) significantly reduced the impact of pre-emergence herbicides, while hoeing 37 DAS resulted in better weed control and higher seed cotton yield.From this study, it can be concluded that intercultural tillage might reduce the impact of pre-emergence herbicides in field cotton crop.However, the timing of the intercultural operations has to be carefully decided for a better integrated weed management.
