Farmers can employ several strategies to manage insect pests and plant diseases, including crop rotation, use of resistant crop varieties, biological control (introducing natural predators or pathogens of pests), cultural practices (such as proper irrigation and sanitation), and judicious use ...

Plant pathogens can be present in various environmental sources such as soil, water, and air. They spread through mechanisms like wind dispersal, water runoff, and soil contamination. Once pathogens come into contact with susceptible plant hosts, they can infect the ...

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.
