Is the pesticide formula patented?

There are many pesticide formulations. If it is a conventional dosage form, its dosage form and additives used have basically been protected by patents applied by others. It will be difficult to get authorization if you apply again. Even if it is not a patent, it can only be said that it is a commercial technology and a commercial secret with certain commercial value. If it is a pesticide formulation, and it has not been applied for by searching the existing patents, it can still be authorized, but it must be novel and creative.
