Weed control efficiency of unmanned aerial vehicle (UAV) spray in replanting oil palm plantation areas

Efficient chemical weed management considers precise application of herbicides, maximizing herbicide retention and absorption, reducing the impact of abiotic factors, and mitigating offtarget movement in order to optimize herbicide efficacy. Hence, this study assessed the employability and cost-effi...
