Darrick Rickziram Ziram 27% SC Contact Fungicide for Downy Mildew, Scab, Anthracnose & Blight

Darrick Rickziram is a broad-spectrum contact fungicide containing Ziram 27% SC (Suspension Concentrate). Ziram belongs to the dithiocarbamate (carbamate) chemical group and works as a multi-site contact protectant. It is specially formulated to safeguard crops from common fungal diseases such as downy mildew in grapes, scab in apples, and early blight in potatoes and tomatoes.

As a suspension concentrate, Rickziram offers uniform spray coverage and strong adherence to leaf surfaces. Its multi-site mode of action disrupts fungal spore germination and mycelial growth, creating a protective barrier on the plant that prevents infections from taking hold. Because it acts on multiple biochemical processes at once, the risk of the fungus developing resistance is very low, making it a dependable choice for repeated seasonal use.

Rickziram is suitable for a wide range of crops including grapes, apples, citrus, vegetables, pulses, and oilseeds. It is used preventively, meaning it is best applied before disease appears or at the very first signs of infection. The liquid SC formulation is easy to mix with water and apply through a foliar sprayer, giving farmers a simple and effective way to protect their crop and support healthier, higher-quality harvests.

Key Benefits

• Controls a wide range of fungal diseases including downy mildew, scab, anthracnose, leaf spot, and blights in one product.
• Multi-site contact action keeps the risk of resistance build-up in fungus very low, so the product stays effective over repeated use.
• SC (Suspension Concentrate) formulation gives uniform spray coverage and strong adherence to leaf surfaces for reliable protection.
• Works as a preventive protectant, creating a long-lasting protective barrier that stops infection before it spreads.
• Easy to use — simply mix with water and spray through a foliar sprayer for hassle-free application.
• Supports healthier crop growth and better-quality produce, leading to improved yield and higher profits.

How It Works

Rickziram works as a contact protectant fungicide. This means it stays on the surface of the plant rather than being absorbed into the plant tissues. When sprayed on the leaves, it forms a protective layer that comes into direct contact with fungal spores and stops them from germinating and growing.

The active ingredient Ziram acts on multiple biochemical sites within the fungus. This multi-site action disrupts spore germination and the growth of mycelia (the thread-like body of the fungus), preventing the disease from establishing itself on the crop. Because the fungus would need to change at several points at the same time to survive, the chance of resistance developing is very low.

Since it is a preventive product, Rickziram gives the best results when applied before disease appears or at the very early stage of infection. The SC formulation ensures the product spreads evenly and sticks well to both sides of the leaves, giving thorough coverage and a long-lasting protective effect.

For mixing and spraying:

• Use 3 ml of product per liter of water.
• Use 45 ml per 15-liter spray pump.
• Dilute the recommended dose in 300–400 liters of water per acre for even coverage.

When to Use

Rickziram is a preventive fungicide, so timing is important for getting the best protection. Apply it before disease appears or at the very first signs of infection for maximum effectiveness.

• Grapes: Apply from pre-flowering to berry set stage to protect against downy mildew and anthracnose.
• Apple: Apply from pre-flowering to fruit set stage to control scab.
• Potato: Apply from vegetative to tuber stage to manage early blight.
• Tomato: Apply from vegetative to flowering stage to control early blight.

During conditions favourable for disease development, such as humid or wet weather, maintain a spray interval of 7–10 days to keep the protective barrier active.

Step by Step Usage Instructions

1. Wear protective gloves, goggles, and a mask before handling the product.
2. Mix the recommended dose in a small amount of water first, then add more water to reach the required spray volume (300–400 liters per acre).
3. Spray evenly on both sides of the leaves for complete coverage.
4. Apply preventively or at the early signs of disease for best results.
5. Maintain a spray interval of 7–10 days during favourable (humid/wet) conditions.
6. Observe a pre-harvest interval of 15–20 days, depending on the crop.
