Directions and How to Use

When to Use

What is Mancozeb and how does it work as a fungicide?

Mancozeb is a broad spectrum contact fungicide belonging to the dithiocarbamate group, specifically classified as Group M3 for resistance management. It works by interfering with multiple enzyme systems in fungal cells, disrupting cellular processes and preventing spore germination. Unlike systemic fungicides, Mancozeb provides protective action on plant surfaces where it’s applied.

Mancozeb is a contact fungicide, not systemic. This means it works by direct contact with fungal spores and mycelium on treated plant surfaces, providing protective action rather than moving through the plant’s vascular system.

Mancozeb contains manganese and zinc as a coordination complex with ethylene bisdithiocarbamate. Application rates typically range from 150-200g per 100L for dilute sprays, or 1.7-6kg per hectare depending on crop and disease.

Mancozeb effectively controls fungal diseases on vegetables (tomatoes, potatoes, beans), fruit crops (citrus, stone fruit, grapes), ornamentals, turf, and field crops. Common diseases controlled include early and late blight, downy mildew, black spot, rust, anthracnose, and scab.

Kendon holds APVMA registration for BANANAS in Australia. This product effectively controls Black pit, Leaf spot (Sigatoka disease), Cordana leaf spot, fruit & leaf speckle and Anthracnose in Bananas.

* SURFACTANTS
The addition of agricultural surfactants to Kendon Mancozeb WG Agricultural Fungicide will improve initial spray deposits, fungicide redist ribution and weatherability. Kendral 600 has been especially formulated to o ptimise the performance of foliar applied agricultural chemicals. Add 10 to 40mL per 100L of spray according to label directions for Kendral 600. There a re other proprietary brand surfactants available, however before using check manufac turers recommendations.
(Always read the label prior to use)

Mancozeb is compatible with most commonly used agricultural fungicides and insecticides. However, do not mix with lime sulphur, and always check manufacturer compatibility recommendations before tank mixing. Add Mancozeb to the spray tank first, then add other products after it’s in suspension.

Withholding periods vary by crop: 7 days for beans, celery, cole crops, cucurbits; 14 days for tomatoes, fruit crops, ornamentals. Always consult the product label for specific crop requirements as these are APVMA registered conditions.

Mancozeb breaks down rapidly in soil and water to natural products without bioaccumulation. However, organic certification requirements vary by certifying body, so check with your organic certifier regarding approved fungicide lists.

Store in original containers in a dry, cool, well-ventilated area away from direct sunlight. When handling, wear appropriate protective equipment including cotton overalls, gloves, goggles, and dust masks. The product may cause allergic skin reactions and respiratory irritation.
