Biological efficacy
A measure of the performance of plant protection products, indicating the degree of suppression of pests or diseases compared to an untreated control group.

Biological efficacy is essential for evaluating the success of pest management strategies. It quantifies the reduction in pest populations or disease severity, providing a clear metric to compare different treatment programs under field conditions.
Agronomists rely on this metric to ensure that selected inputs provide the necessary protection without wasting resources. Low efficacy scores often signal potential issues, such as pest resistance, poor application timing, or inadequate equipment calibration during field operations.
A common mistake is failing to account for environmental variability when measuring outcomes. It is crucial to correlate efficacy with local weather patterns, as temperature and humidity significantly influence the biological performance of most agricultural chemicals.
