Weed-control products in Pará can be found at most agricultural supply stores, cooperatives, and rural input distributors. Look for establishments that sell legally registered herbicides for crops such as soybean, corn, and vegetables. When visiting a store, ask for products approved for your specific crop and weed type, and always follow local regulations and safety guidelines. Many cities in Pará—like Belém, Santarém, Marabá, and Paragominas—have agro-shops offering selective and non-selective herbicides, along with technical assistance.
