Organic pest management decisions: a systems approach to technology adoption
利用1997年美国有机农户调查数据，研究农户在病虫害、线虫和杂草管理策略上的采纳决策，发现杂草管理最费力，信息搜寻、农场实验、教育程度和有机承诺强度正向影响杂草控制策略数量。
Abstract Organic farmers make system‐level crop protection decisions that combine complementary insect, disease, nematode, and weed management strategies. Data from a 1997 national survey of U.S. organic farmers were used in a multivariate count data model to identify the farm and regional factors influencing the adoption of practices across the linked pest management categories. The results show that weed management requires the greatest management effort by organic farmers. More intensive information‐seeking and on‐farm experimentation, higher educational attainment, and intensity of commitment to organic farming are positively related to the number of weed control strategies adopted. Predictions of adoption based on this model and customized to farm and region specifications will give information providers lead time to develop technical support for reduced chemical pest management systems.
