Rallis Captaf Fungicide: Product Overview
Rallis Captaf is a wettable-powder contact fungicide containing Captan 50% w/w WP. The approved Indian label lists it for specific fungal diseases in grapes, potato, cherry, tomato and apple.
Captaf is classified by FRAC as Group M04, a phthalimide fungicide with multi-site contact activity. As a contact product, it depends on a properly mixed spray and thorough coverage of the target crop surface. It should not be presented as a systemic, curative or eradicant fungicide.
All five registered rows use the same hectare direction: 1.25 kg active ingredient/ha, equal to 2.5 kg formulation/ha, diluted in 750-1000 L water/ha. The label calls for foliar application using a high-volume sprayer, with 1-2 sprays depending on disease pressure. Do not turn these directions into an unsupported universal per-litre, per-pump or per-acre dose.
