Chemical control of fungous growth depends upon the performance of the fungicide when it is deposited in small amounts on the treated surface. The regulation of fungicidal action depends upon the use of the material to be protected. With agricultural products, the fungicide should be effective for a limited period of time. When mixed with soil, the residues must be nontoxic to plants at the time of planting. Edible crops must be free from fungicide at harvest. However, when applied to textiles, wood, and manufactured products, the fungicide should prevent deterioration during the life of the product. To control mycotic infections of animal and man, the fungicide must be nontoxic to the host. Thus, an understanding of the underlying factors is imperative in order to restrict performance to the time required.
