Formulation professionals are increasingly facing big challenges in the development of new products containing a mixture of multisite active ingredients. In Brazil, where the climate is hot and humid for most of the year, conditions are perfect for the emergence of pests, which daily grow more resistant to the formulations available in the market. To keep a check on application dosages to reduce costs and waste, and damage to the environment, there is growing demand for the development of products that contain a mix of compounds with complementary biological activities for effective crop protection.
