This document discusses the mode of action, formulations, and factors influencing the field performance of fungicides. It describes three main modes of action for fungicides - contact fungicides with protective action only, contact fungicides with both protective and therapeutic action, and systemic fungicides with therapeutic action. It then lists seven common fungicide formulations - wettable powders, wettable granules, slurries, dusts, suspenible concentrates, emulsifiable concentrates, and dispersible concentrates. Finally, it outlines physical factors like deposition and tenacity and chemical factors like photolysis and hydrolysis that can influence a fungicide's performance in the field.
