Application of Herbicides and Other Biotic Control Agents
摘要
The main characteristics of pesticides from an agronomic viewpoint are selectivity, mobility within the plant, and toxicity on nontarget plants, insects, and other fauna. Pesticide application should maximize the protective effect while preventing drift, which is increased with high wind speed, unstable conditions, and high evaporative demand. There is a general trend in pest control toward less persistent molecules with lower environmental impacts. Pesticide doses may be adjusted according to the actual canopy volume (TRV method) for trees and Leaf Area Index in annual crops.
