Effects of Insecticide Attributes on Within‐Season Insecticide Product and Rate Choices: The Case of U.S. Apple Growers
利用随机效用框架，基于美国农业部调查数据，分析杀虫剂功效、环境安全、用户安全及监管属性如何影响苹果种植者当季对产品和用量的选择，发现功效和用户安全分别对产品和用量选择影响最大。
Abstract We use a random utility framework to examine within‐season choices of insecticide products and application rates made by U.S. apple growers. Impacts on pesticide choices of insecticide efficacy, environmental safety, user safety, and regulatory attributes, as well as integrated pest management (IPM) practices, are investigated using cross‐sectional data from the USDA Fruit and Nut Chemical Use Survey. The results show that the product and rate choices are most influenced by efficacy and user safety attributes, respectively. Impacts of IPM practices are mainly on the choice of insecticide products, but effects differ by practice and by product.
