Propineb 70% WP Fungicide Uses

Propineb 70% WP is a broad-spectrum, protectant (contact) fungicide from the dithiocarbamate chemical group, registered for use in India under the Insecticides Act, 1968, formulated as a wettable powder (WP). It is registered for the control of scab, leaf and fruit spot, blight, die-back, buckeye rot, downy mildew and brown/narrow leaf spot across fruit, vegetable, plantation and field crops. This page lists its mode of action, key benefits and the complete crop-wise recommended dosage as per the Central Insecticides Board & Registration Committee's (CIB&RC) official list of approved fungicide uses.

Mode of Action

Propineb belongs to the dithiocarbamate group of fungicides (FRAC Group M03), a multi-site protectant mode of action. Unlike systemic fungicides that target one specific enzyme, propineb interferes with several enzyme systems in the fungal cell simultaneously — including enzymes involved in cellular respiration — by reacting with thiol (-SH) groups essential to their function. It forms a protective chemical film on the surface of leaves, fruit and stems that prevents fungal spores from germinating and establishing infection. Because it acts purely on the leaf/fruit surface with no movement into plant tissue, it must be applied before infection occurs and reapplied to protect new growth, but its multi-site action makes fungal resistance to it far less likely to develop than with single-site systemic fungicides.

Features & Benefits

• Multi-site protectant action across scab, leaf/fruit spot, blight, die-back, buckeye rot and downy mildew on a wide range of fruit, vegetable and field crops from a single fungicide.
• Very low risk of fungal resistance developing compared with single-site systemic fungicides, making it a valuable rotation partner in a resistance-management program.
• Well suited to tank-mixing with systemic fungicides to broaden the spectrum of control and slow resistance development against the systemic partner.
• Wettable powder (WP) formulation that mixes into a stable spray suspension for uniform tank application.

Recommended Usage of Propineb 70% WP Fungicide

The table below gives the recommended dose for each crop and disease, based on the official rate published in the Central Insecticides Board & Registration Committee's (CIB&RC) list of approved fungicide uses (Government of India). Apple, pomegranate, potato, chilli, tomato and grapes use a percentage-concentration rate rather than a fixed per-hectare quantity, while rice (paddy) and cotton use a per-hectare dose converted to a practical per-acre spray-tank quantity — see the note below the table for the full breakdown. Always spray in sufficient water volume for uniform coverage, and confirm against the current product label before use.

For apple, pomegranate, potato, chilli, tomato and grapes, doses above are drawn directly from the CIB&RC's list of approved fungicide uses (Government of India), which expresses this product's rate as a percentage concentration/quantity per 100 litres of water rather than a fixed per-hectare dose, since total spray volume for tree and vegetable crops varies with plant size, crop stage and the spray equipment used. For rice (paddy) and cotton, the CIB&RC source states the rate per hectare; converted here to a practical per-acre quantity (1 ha ≈ 2.47 acres) and rounded. The source table does not list a waiting period for the rice (paddy) use, so none is stated above rather than guessed — confirm this directly from the current product label. Always confirm the current dose and total spray volume on your specific product's label, and consult your local agricultural extension office if in doubt.

How to Use

1. Identify your crop and target disease from the table above, and confirm the correct concentration/dose and total spray volume for your plant size/crop stage.
2. Mix the measured quantity of Propineb 70% WP into a small quantity of water to form a smooth paste first, then add this paste to the spray tank with the remaining water and agitate thoroughly.
3. Apply as a fine, uniform spray covering the entire plant surface — leaves, stems and fruit — since this is a protectant fungicide that must coat the surface before infection occurs.
4. Begin spraying before disease onset, or at the very first appearance of symptoms, since propineb works preventively rather than curing existing infections.
5. Repeat sprays at 10–15 day intervals through the susceptible growth period, or as advised by local agricultural extension, reapplying after heavy rain which can wash off the protective film.

Precautions & Safety

• Wear appropriate PPE — mask/respirator, gloves, goggles and full-sleeved clothing — while mixing and spraying, and avoid inhaling spray mist or dust from the wettable powder.
• As a multi-site protectant, resistance development is uncommon, but repeated exclusive reliance on any single fungicide is best avoided — rotate or tank-mix with other fungicide groups as part of good resistance-management practice.
• Follow the recommended concentration/dose strictly — both underdosing (poor disease control) and overdosing reduce field performance and increase cost.
• Respect the waiting period (PHI) given in the table above and on the current product label before harvesting the treated crop.
• Store in the original, tightly closed container in a cool, dry place away from direct sunlight, food and feed, and out of reach of children and livestock.
• Wash hands, face and any exposed skin thoroughly with soap and water after handling or spraying, and change out of contaminated clothing before eating, drinking or smoking.
