Applying the Economic Threshold Concept to Control Lesion Nematodes on Corn

摘要

Determining economic thresholds for various lesion nematode controls can help corn producers decide whether to apply aldicarb and estimate the profit-maximizing dosage. The economic threshold, the population density at which a pesticide dosage is economically justified, is a key concept in pest management economics; few economists have applied it empirically. Optimal dosages of aldicarb are usually profitable and increase at a decreasing rate as nematode populations or corn prices increase.
