Description

Amistar Fungicide

Protect your crops with Amistar, a broad-spectrum fungicide from Syngenta, featuring azoxystrobin (250g/L) as its active ingredient in a soluble concentrate (SC) formulation. Belonging to the strobilurin group (Fungicide Group 11), Amistar offers systemic, translaminar, and protectant properties, making it ideal for Integrated Crop Management (ICM) programs in Kenya. Distributed by suppliers like Organic Farm, Virtual Agrovet, and Imagine Care, Amistar controls a wide range of fungal diseases, enhances crop vigor, and boosts yields. Available in 1L, 5L, and 20L packs, it is suited for various crops grown in regions like Machakos, Nakuru, and Kisumu.

Benefits of Amistar Fungicide

• Broad-Spectrum Control: Effectively manages fungal diseases like rust, powdery mildew, downy mildew, leaf spots, and anthracnose across multiple crops, ensuring healthy growth.

• Systemic and Translaminar Action: Azoxystrobin moves acropetally in the xylem and penetrates leaves, providing preventive and early curative protection by inhibiting fungal respiration.

• Yield and Quality Enhancement: Preserves green leaf area (GLA), delays senescence, and improves nitrogen use efficiency, leading to higher yields (up to 20% increase) and better crop quality.

• Physiological Benefits: Promotes greening effects, enhances abiotic stress resistance (e.g., drought), and improves nutrient assimilation, contributing to robust plants.

• Eco-Friendly Integration: Safe for crops when used as directed, with a unique mode of action that complements ICM strategies, reducing reliance on other fungicides.

Suitable Crops for Amistar

Amistar is approved for a wide range of crops in Kenya, including those previously discussed:

• Cereals: Maize (e.g., SC Sungura 301) – controls grey leaf spot, leaf blight, common rust.

• Legumes: Beans (e.g., Kazuri, Nyota, RoseCoco GLP 2, Yellow Beans KAT B1) – manages anthracnose, angular leaf spot, rust.

• Vegetables: Onions (e.g., Red Creole, Russet F1) – controls foliar diseases; Spinach (e.g., Indian Palak) – targets downy mildew, leaf spot; Pumpkins (e.g., Elgon Cream) – controls powdery mildew.

• Other Crops: Potatoes (early/late blight), tomatoes (late blight), peas (powdery mildew), roses (powdery mildew), and ornamentals (Botrytis, black root rot).

Note: Avoid use near apple crops due to azoxystrobin sensitivity; do not use spray equipment on apples after applying Amistar.

Target Diseases

Amistar effectively controls pathogens from Ascomycetes, Basidiomycetes, Deuteromycetes, and Oomycetes, including:

• Maize: Grey leaf spot (Cercospora zeae-maydis), common rust (Puccinia sorghi).

• Beans: Anthracnose (Colletotrichum lindemuthianum), angular leaf spot, rust.

• Onions: Downy mildew, foliar diseases.

• Spinach: Downy mildew, leaf spot.

• Pumpkins: Powdery mildew (Sphaerotheca fuliginea).

• Others: Early/late blight, septoria, fusarium, white blister, Botrytis.

Application Guidelines

Amistar is best applied preventively or at the earliest signs of disease, following a risk assessment or decision support system. It should be used in a program with fungicides of different modes of action to prevent resistance.

Application Rates and Timing

1. Maize (SC Sungura 301):

   • Rate: 10–15ml per 20L water (0.5–1L/ha).

   • Timing: Apply at early vegetative stage or first signs of grey leaf spot/rust, typically 4–6 weeks post-emergence. Repeat after 12–14 days if needed (max 2 applications per season).

2. Beans (Yellow Beans KAT B1, Kazuri, Nyota, RoseCoco):

   • Rate: 10ml per 20L water (0.5L/ha).

   • Timing: Apply at flowering stage (30–40 days) to protect against anthracnose and rust. One application is usually sufficient; max 2 per season.

3. Onions (Red Creole, Russet F1):

   • Rate: 10ml per 20L water (0.5L/ha).

   • Timing: Apply post-transplanting (3–4 weeks) or at early disease onset. Repeat after 12 days (max 2 applications).

4. Spinach (Indian Palak):

   • Rate: 10ml per 20L water (0.5L/ha).

   • Timing: Apply 2–3 weeks post-emergence for downy mildew control, ideally before first harvest (25–30 days).

5. Pumpkins (Elgon Cream):

   • Rate: 10ml per 20L water (0.5L/ha).

   • Timing: Apply at early flowering or first signs of powdery mildew (30–40 days). Repeat if necessary (max 2 applications).

Application Method

• Foliar Spray:

  • Mix Amistar with water in a knapsack sprayer (e.g., 10ml in 20L for small-scale farms).

  • Use a fine nozzle to ensure even coverage, penetrating the canopy and coating lower leaves. Adjust spray volume (200–400L/ha) and pressure for optimal distribution.

  • Apply in the early morning or late afternoon to avoid leaf burn and ensure rainfastness within 2 hours.

• Program Approach: Combine with non-QoI fungicides (e.g., RANSOM 600WP, 15g/20L) to manage resistance, especially for septoria or powdery mildew.

• Pre-Harvest Interval: Apply up to 14 days before harvest for most crops; observe a 12-day interval between applications for brassicas.

Compatibility

• Compatible with BIOFIX, Easy Gro Starter, MycoApply Endo Prime EA, and Vuna Fertilizer for integrated nutrient and pest management.

• Incompatible with systemic fungicides like Triadimefon or Benomyl; allow a 2-week interval before/after their use.

Soil and Climate Compatibility

• Soil Type: Effective in well-drained loamy or sandy loam soils; pH 6.0–7.0. Best results with adequate soil moisture.

• Climate: Suitable for temperatures of 15–33°C and rainfall of 250–2,000mm, covering semi-arid to highland zones (0–2,500m).

• Regions: Machakos, Makueni, Nakuru, Kisumu, Kirinyaga, Nyeri, and other crop-growing areas in Kenya.

Expected Impact

• Yield Increase: Up to 20% yield improvement (e.g., Yellow Beans KAT B1: 7–9 bags/acre to 8–11 bags/acre; SC Sungura 301 Maize: 25–30 bags/acre to 30–36 bags/acre).

• Income: Enhances profitability (e.g., KSh 420,000–630,000 to KSh 480,000–770,000 per acre for Yellow Beans at KSh 6,000–7,000 per 90kg bag).

• Crop Health: Maintains GLA, reduces disease incidence, and improves stress tolerance, ensuring marketable produce.

Pricing and Availability

• Price: KSh 1,999–4,500 for 1L; KSh 300–500 for 50ml (varies by supplier).

• Suppliers: Organic Farm, Virtual Agrovet, Imagine Care, Agroduka, Shambaza.
