　　For a long time, whiteflies have been a pest on certain crops in South America, such as vegetables and fruits, Cotton 、 Soybean ) is an important pest, but in recent years the primary reason for the explosive proliferation of whiteflies has been the development of resistance, a situation that is particularly severe in Brazil’s savannas.
　　Luís Fernando Andrade, product manager at Ihara Pesticides, said: “High temperatures and large-scale monoculture…” Soybean Cultivation has resulted in rather unsatisfactory control efficacy for some products, and this pest is among the most significant… Soybean The disease is spreading across the production area.
　　Alexandre Manzini, Product Manager for Nufarm’s insecticides, said: “In the final stages of the harvest, climatic conditions have led to a significant reduction in pest incidence.”
　　Key factors in the prevention and control of whiteflies
　　Andrade said, “There are several key considerations in whitefly management, including controlling host weeds, implementing crop rotation, and employing chemical control with insecticides. Most importantly, it is crucial to select the right product. Whiteflies lay an average of 300 eggs; to achieve effective control, products must be effective against eggs, nymphs, and adults, meaning the insecticide must remain active throughout the entire life cycle of the pest.”
　　Manzini recommends initiating control measures at the early stage of an infestation: “The first application should target and disrupt whitefly reproduction, with one product aimed at killing adults and another used to manage eggs and nymphs. A second application should follow, tailored to the results of crop monitoring.”
