Defoliator

A defoliator is an agent, typically an insect, disease, or chemical substance, that causes the premature shedding of leaves from a plant. This process, known as defoliation, weakens the plant by reducing its ability to photosynthesize, thereby hindering growth, fruit production, and overall health. Defoliators can range in severity, from minor damage to complete stripping of foliage. The impact of defoliation varies based on the plant species, the defoliator's intensity, and the environmental conditions. In forestry and agriculture, defoliators pose significant economic threats, necessitating pest management strategies to mitigate their effects. The study and control of defoliators are vital for sustainable plant health.
