Captan is a broad spectrum protectant fungicide used in agriculture to control various fungal diseases in crops. Its mode of action typically involves the inhibition of spore germination and mycelial growth, making it effective against a wide range of pathogens, including those that cause notable diseases in fruits, vegetables, and ornamental plants. This versatility is crucial for ensuring healthy crop yields and is a reason why it is widely used in the agricultural sector.

It's important to note that while some may confuse fungicides with herbicides or insecticides, Captan specifically functions as a fungicide, targeting fungal pathogens rather than weeds or insects. The definitions of selective herbicides, inorganic fertilizers, and pesticides for insect control pertain to different classes of chemicals that serve unique purposes in plant management and pest control.
