This entails identifying and controlling weed, insect, and disease-related issues that have the potential to seriously compromise crop health and productivity. While insects and illnesses can directly harm crops or cause crop loss, weeds compete with crops for the same nutrients. To find these problems, field monitoring must be done on a regular basis to look for disease or infestation indicators. Once recognised, there are a number of strategies that may be employed to address these problems, such as crop rotation, insecticides, and disease-resistant crop types. However, because of the possibility for pesticide resistance in diseases and pests as well as environmental concerns, sustainable approaches are frequently used. An important tactic is integrated pest management, which employs a variety of techniques to manage illnesses and pests while lowering the need for chemical pesticides and preserving the ecosystem. This covers cultural and biological control strategies, such as changing farming techniques to create an environment that is less conducive to illnesses and pests, and the use of natural insect predators.
