  • Applications

    Pencycuron is used in agriculture as a fungicidal active ingredient formulated for seed-treatment and soil-applied products to protect crops from root- and seedling diseases caused by soilborne fungi, notably Rhizoctonia solani, in crops such as potatoes, cereals, and vegetables; it is commonly applied as seed coatings or soil-applied formulations and may be evaluated for nursery or greenhouse use as part of crop establishment; it can be used in tank mixes with other fungicides within approved label guidelines; all use is subject to local regulations and formulation limits.
