Plant diseases are caused by pathogens such as bacteria, fungi, and viruses. Examples include bacterial blight, fungal rusts, and viral mosaic diseases.

Insect pests can significantly affect crop health by causing physical damage to plant structures and by reducing the plant’s ability to carry out essential functions like photosynthesis. This damage often leads to reduced yields and overall crop productivity.

Insect pests damage plants by cutting the roots, stems, and leaves; sucking the cell sap from various plant parts; and boring into stems and fruits.

Integrated pest management combines multiple approaches, including biological, cultural, and chemical methods, to manage pests and weeds in a sustainable and environmentally friendly manner. By integrating various control measures and monitoring pest populations, farmers can reduce reliance on chemical pesticides ...

Farmers can employ various strategies such as mechanical methods (like hand weeding or using machinery), cultural practices (crop rotation, mulching), chemical herbicides, and biological control methods (introducing natural predators or pathogens of weeds).
