Assessing Environmental Impacts of Genetically Modified Seeds in Brazilian Agriculture
Renato Seixas and José Maria Silveira
Using a farm-level dataset on genetically modified (GM) seed adoption and pesticide application in Brazil, we find that Insect Resistant (IR) cotton reduces the environmental impact of insecticides but Herbicide Tolerant (HT) soybeans increase the environmental impact of herbicides due to weak substitution among herbicides of different toxicity levels.
