Systemic Fungicide Plus
A dual-mode systemic fungicide combining curative and preventive action. Stops existing fungal infections while protecting healthy tissue from new disease spread — essential for high-value vegetable and fruit crops.
How to Use
Identify the Disease
Look for water-soaked lesions, white powdery growth, or brown leaf spots. Systemic Fungicide Plus is most effective against oomycete diseases like late blight and downy mildew. For powdery mildew, consider a sulphur-based fungicide instead.
Mix the Solution
Dissolve 20–25 g per 10 litres of water. Add the powder to half-full water tank, stir well, then top up. The mix turns milky — this is normal. Use immediately; do not store mixed solution.
Apply Preventively or Curatively
For prevention, start spraying at first signs of wet/humid weather favourable to disease (early morning fog, rainy periods). For curative use, apply as soon as symptoms are first observed — do not wait for widespread infection.
Thorough Coverage
Cover all leaf surfaces completely, including undersides where spores germinate. Use a fine mist setting and spray until just before runoff. Canopy size determines volume — use 200–400 L/ha.
Repeat Applications
Repeat every 7–10 days during high disease pressure periods (rainy season, heavy dew). In dry seasons, intervals can extend to 14 days. Maximum 4 applications per season.
Clean and Store
Rinse sprayer thoroughly after use — Mancozeb residue can be corrosive to metal parts. Store unused product sealed in original container in a cool, dry place. Shelf life: 2 years from manufacture date.
Key Features
Dual Protection
Metalaxyl penetrates plant tissue systemically; Mancozeb forms a protective surface barrier — two modes work together for complete cover.
Rainfast in 2 Hours
Once dried the spray film resists wash-off during light rain, maintaining effectiveness through Tanzania's heavy short-rain season.
Multi-Crop Registered
Approved for tomatoes, potatoes, onions, grapes, and most leafy vegetables at standard application rates.
Curative Window
Metalaxyl component can arrest fungal growth up to 48 hours after infection — effective even after symptoms appear.
Cost-Effective Formulation
WP (Wettable Powder) formulation provides more active ingredient per gram compared to emulsifiable concentrates at equivalent price.
Crop Quality Improvement
Healthy foliage free of disease maintains photosynthesis efficiency — directly linked to fruit size, weight, and marketable yield.
Disease Management & Safety Tips
- Alternate with a strobilurin fungicide (e.g., azoxystrobin) every 2nd application to manage resistance in late blight populations — a critical concern for potato and tomato growers in Tanzania.
- Apply before or immediately after rainfall events — spores spread rapidly in wet conditions and the protective layer needs to be in place before infection occurs.
- Mancozeb is a contact irritant — always wear gloves, goggles, and a respirator during mixing and spraying. Wash hands and face after any contact.
- Do not mix with highly alkaline pesticides (e.g., copper hydroxide) as this can break down the Metalaxyl component and reduce efficacy.
- Observe the 10-day pre-harvest interval strictly for export crops where MRL testing is conducted at port.
