Weed-related challenges in Pakistan include high financial loss due to weed infestation in economically important crops, invasion of managed and natural ecosystems by alien invasive weeds, floral shifts in weed communities, and the evolution of herbicide-resistant biotypes of major weeds. Labor shortages during the critical period of weed removal, limited automation, and fault lines in implementing and maintaining weed control are significant concerns. Conventional agronomic practices and weed management approaches are insufficient to combat the weed menace and sustain crop productivity. Research on weed ecology and related management aspects, although scanty in Pakistan, is still crucial for a better understanding of how weeds grow, spread, and impact agroecosystems. In this context, improved knowledge of weed ecology and biology (weed germination, seedling emergence, growth, reproductive potential, and seed dormancy) seems indispensable for developing sustainable weed management practices. This will assist in the development of ecologically based weed management approaches, especially in response to evolving cropping systems and related crop management practices under changing climatic patterns. Weeds respond to environmental and edaphic factors under diverse agroclimatic conditions of Pakistan in a complex manner and prompt an in-depth exploration of weed eco-biology considering environmental influences, biological traits, and adaptive management practices. As the country continues to face challenges like climate change, water scarcity, and increasing herbicide resistance, strategic research and innovations will be the key to mitigating the adverse impacts of weeds on food security and the country’s economy. There is an urgent need to reorient weed research in Pakistan toward a more holistic framework that emphasizes ecological understanding, long-term monitoring, and integrated weed management principles. Besides conventional weed management approaches, innovations in weed management like drone-enabled mapping and precision spraying, artificial intelligence (AI)–driven robotics, use of thermal or laser weeders, biodegradable carrier-based nanoherbicides, herbicide-resistant crops, RNAi-mediated spray-induced gene silencing, and harvest weed seed control need to be considered for technological adoption and diffusion at the farm level.
