Chemical control is a research area that focuses on the use of chemicals or chemical compounds to manage or control pests, pathogens, and weeds in agricultural systems. This can involve the development and use of chemical pesticides, herbicides, and fungicides to protect crops from damage and ensure higher yields. Chemical control research also encompasses the study of the effectiveness, safety, and environmental impact of these chemicals, as well as exploring alternative methods of pest control to reduce reliance on chemical interventions. Overall, the goal of chemical control research is to improve crop protection and agricultural productivity while minimizing negative impacts on human health and the environment.
