1. Prochloraz Industry Overview

Prochloraz is a broad-spectrum imidazole fungicide used to control a diverse range of fungal diseases in crops and ornamentals. The application of prochloraz extends notably to cereals, fruits, and vegetables, especially within regions such as Europe, Australia, Asia, and South America (FAO JMPR).

The demand for prochloraz fungicide has steadily increased due to rising awareness of crop security, continued agricultural intensification, and stringent quality standards in food trade. In addition, the global prochloraz 24.4 formulation is gaining traction for its efficacy and ease of field application.

2. Technical Parameters of Prochloraz
Parameter Specification Description
Chemical Name Prochloraz 1-[2-(2,4,6-Trichlorophenoxy)ethyl]-1H-imidazole
Molecular Formula C15H16Cl3N3O2 Defines structure and composition
Molecular Weight 376.7 g/mol Molar mass for accurate formulation
Appearance White to off-white powder Fine crystalline or powder form
Content (% w/w) ≥ 97.0 (TC) Technical grade minimum purity
Melting Point 144–147°C Ensures appropriate storage/handling
Solubility Low (in water) Soluble in organic solvents—essential for emulsifiable concentrate
Formulation 24.4% EC, 45% SC, 50% WP Prochloraz 24.4 is commonly used for foliar spray
Toxicity Moderate (to mammals & birds) Low bioaccumulation, eco-toxicity profile improves usage confidence
3. Application Scenarios for Prochloraz Systemic Fungicide
  • Crop Protection: Primarily for cereals (wheat, barley), fruit trees (citrus, apples), vegetables (tomatoes, cucumbers), and ornamentals.
  • Mode of Action: Systemic translocation—penetrates plant tissues and fends off pathogens such as Botrytis, Alternaria, Rhizoctonia, and Fusarium species (PubChem).
  • Soil Treatment: Used to manage root rot, collar rot, and damping-off in nurseries and greenhouse crops.
  • Seed Treatment: Provides protection during germination in cereals and grain-based crops.
  • Post-Harvest Usage: Controls post-harvest spoilage and fungal contamination in storage environments.
4. Prochloraz Industry Trends & Market Perspective

Global adoption of prochloraz systemic fungicide is driven by rising demands for resilient agriculture, especially under climate-related stress on crops. Technological advances in formulation of prochloraz 24.4 (24.4% w/w Emulsifiable Concentrate) are improving bioavailability and reducing environmental risk profiles. Regulatory agencies, such as the European Food Safety Authority (EFSA), periodically update guidelines to ensure safety, limiting maximum residue levels (MRLs) and shaping trade flows.

7. Professional Q&A: Prochloraz Systemic Fungicide
Q1: What is the chemical structure and mode of action of prochloraz?
A1: Prochloraz features an imidazole nucleus linked to a trichlorophenoxy group. It inhibits ergosterol biosynthesis by interfering with fungal cytochrome P450 monooxygenases, leading to fungal cell membrane collapse. [Source]
Q2: What are the main industrial formulations of prochloraz for agriculture?
A2: Commercial formulations include Prochloraz 24.4 EC (Emulsifiable Concentrate), 45% SC (Suspension Concentrate), and 50% WP (Wettable Powder). Their usage depends on crop species, targeted pathogens, and application environment.
Q3: How does prochloraz systemic fungicide work in field applications?
A3: It is absorbed by leaf and root tissues, moves systemically, and suppresses fungal pathogen development both preventatively and curatively.
Q4: What are the recommended application rates and MRLs for prochloraz in food crops?
A4: Application rates vary (typically 0.2–1.0 kg a.i./ha), with MRLs (Maximum Residue Limits) set by regulators—for example, 0.3 mg/kg in the EU, 2.5 mg/kg in India. Always refer to the latest official guidelines.
Q5: How should Prochloraz 24.4 EC be stored and handled?
A5: Store in cool, dry, and ventilated environments. Avoid exposure to direct sunlight or moisture. Follow material safety data sheet (MSDS) procedures to ensure operator safety.
Q6: What is the environmental impact and toxicity profile of prochloraz?
A6: Prochloraz has a moderate-to-low toxicity to mammals/birds and tends to degrade in soil, minimizing risk of bioaccumulation. Its eco-toxicology is well-documented in the EFSA Journal.
Q7: What are the primary storage and shelf-life requirements for prochloraz fungicide?
A7: Keep container111s tightly sealed, away from heat and frost. Shelf life is generally 2 years under standard conditions in original packaging.
