Prochloraz -Prevention and control of various fungal diseases- CAS: 67747-09-5

Prochloraz (CAS 67747-09-5) 

Product Name: Prochloraz 

Tagline: A broad-spectrum imidazole fungicide for systemic protection against fungal diseases in crops.

Key Advantages:

Controls Fusarium, Botrytis, and powdery mildew pathogens

Dual action: Protective and curative activity

Low phytotoxicity and residue risk

Compliant with integrated pest management (IPM) strategies

Prochloraz is engineered for both preventive and curative disease control, making it a versatile solution in the fungicide portfolio. It acts by disrupting the biosynthesis of ergosterol, a key component of fungal membranes, which effectively suppresses mycelial growth and prevents spore germination. This reliable mode of action makes it well-suited for protecting cereals, oilseed rape, fruit, and vegetable crops across a range of climatic conditions.

Broad-Spectrum Control: Effectively targets major pathogens including Fusarium graminearum, Botrytis cinerea, and Erysiphe spp.

Systemic Reliability: Rapidly absorbed and moves within the plant for comprehensive protection.

Resistance Management: Features a unique mode of action (FRAC Group G1), ideal for rotation programs.

User-Focused Design: Minimal dust generation and excellent tank-mix stability for convenient application.

Sustainable Profile: Exhibits low soil persistence, supporting environmental stewardship in farming.

Target Crops:

Cereals (wheat, barley)

Oilseed rape

Citrus, bananas, grapes

Vegetables (tomatoes, cucumbers)

Disease Control:

Fusarium head blight (wheat)

Botrytis gray mold (vegetables, fruits)

Powdery mildew (grapes, cucurbits)

Seed-borne infections (pre-plant treatment)

Application Methods:

Foliar spray (preventive or early infection stages)

Seed treatment (for cereal diseases)

Post-harvest fruit dipping (tropical fruits)

Application Rates:

Foliar Spray: 200–300 g/ha (adjust based on disease pressure)

Seed Treatment: 1.5–2.5 g/kg seeds

Water Volume: 500–1000 L/ha (ensure full coverage)

Mixing Protocol:

Pre-mix in a small container with water to form a slurry.

Add slurry to spray tank under agitation.

Maintain agitation until application is complete.

PPE Requirements: Gloves, goggles, respirator (during mixing).

Environmental Precautions: Avoid runoff to aquatic systems. Toxic to fish and bees-do not apply near waterways or during flowering.

Storage: Keep in a cool, dry place (<30°C). Seal opened bags tightly.

First Aid: Rinse eyes/skin with water if exposed. Seek medical attention if ingested.

Field Trials: 85–95% control of Fusarium head blight in wheat (EU trials, 2022).

Cost Efficiency: Reduces post-harvest losses by up to 40% in citrus.

User Testimonials: "Prochloraz 50%WP saved our vineyard from Botrytis outbreak during rainy seasons." – AgriVine Co., Spain.

Q: Can Prochloraz be mixed with herbicides?

A: Test compatibility first. Avoid alkaline formulations (pH >9).

Q: When is the best application timing for powdery mildew?

A: Apply at first signs of infection; repeat every 10–14 days if needed.

Q: How to manage resistance?

A: Rotate with FRAC Group 3 (triazoles) or Group 7 (SDHIs) fungicides.

Companion Fungicides:

Tebuconazole 25%SC (CAS 107534-96-3)

Azoxystrobin 23%SC (CAS 131860-33-8)

Adjuvants: Non-ionic surfactants for enhanced adhesion.

IPM Kits: Combine with biocontrol agents for organic systems.
