Kendon Mancozeb is a broad-spectrum contact fungicide providing protective action against fungal diseases in vegetables, fruit, field crops, tobacco, turf, and ornamentals. Discovered in 1961, Mancozeb is a complex molecule containing manganese and zinc as active components, which react with amino acids and enzymes in fungal cells to disrupt cellular functions.
Offering reliable disease control through multi-site protective action.

* SURFACTANTS The addition of agricultural surfactants to Kendon Mancozeb WG Agricultural Fungicide will improve initial spray deposits, fungicide redistribution and weatherability. Kendral 600 has been especially formulated to optimise the performance of foliar-applied agricultural chemicals. Add 10 to 40mL per 100L of spray according to label directions for Kendral 600. There are other proprietary brand surfactants available; however, before using, check the manufacturer's recommendations. (Always read the label prior to use)
