Isoprothiolane solution is widely used in agriculture as a systemic fungicide to control rice blast disease, a significant threat to rice crops. It is applied to rice plants to prevent and treat infections caused by the fungus Magnaporthe oryzae. The solution works by inhibiting the growth and spread of the fungus, protecting the plants during critical growth stages. It is typically applied as a foliar spray or mixed with irrigation water, ensuring effective absorption by the plant. Its systemic nature allows it to move within the plant, providing long-lasting protection. Additionally, it is valued for its ability to enhance the plant's natural resistance to the disease, contributing to healthier and higher-yielding rice crops.
