Propisochlor Technical FAQ
Q: What is the mode of action of Propisochlor Technical?
A: Propisochlor Technical inhibits cell division in susceptible weeds by interfering with the synthesis of very-long-chain fatty acids (VLCFAs). This mode of action prevents proper cell membrane formation, ultimately leading to weed growth inhibition and death. The herbicide is absorbed primarily by emerging shoots and secondarily by roots of target weeds.
Q: What are the optimal application conditions for Propisochlor Technical?
A: For best results with Propisochlor Technical, apply to moist soil (but not saturated) with temperatures between 10-25°C (50-77°F). The herbicide requires rainfall or irrigation (10-15 mm) within 7-10 days after application to activate the active ingredient. Avoid applications when heavy rain is expected within 24 hours as this may cause leaching.
Q: How does Propisochlor Technical compare to other chloroacetamide herbicides?
A: Propisochlor Technical offers several advantages over similar herbicides: 1) It provides more consistent control of problematic weeds like barnyardgrass and velvetleaf, 2) It has lower vapor pressure (1.1 × 10-3 Pa) than many alternatives, reducing volatility concerns, 3) The technical grade formulation allows for flexible formulation into various end-use products, and 4) It demonstrates excellent crop safety when used according to label recommendations.
Formulation Options
Propisochlor Technical can be processed into various formulations including:
- Emulsifiable Concentrates (EC)

Additional Propisochlor Technical FAQ
Q: What is the recommended tank mix partners for Propisochlor Technical?
A: Propisochlor Technical shows excellent compatibility with many herbicides including atrazine, metribuzin, and bentazon. The most effective tank mixtures depend on target weeds and crop: 1) For corn: Propisochlor Technical + atrazine provides broad-spectrum control, 2) For soybean: Propisochlor Technical + metribuzin enhances broadleaf control, 3) For cotton: Propisochlor Technical + prometryn offers extended residual activity. Always conduct jar tests before large-scale mixing.
Q: What rotational crop restrictions apply after using Propisochlor Technical?
A: The following rotational intervals apply after Propisochlor Technical application: 1) 4 months for wheat and barley, 2) 9 months for sugarbeets and potatoes, 3) 12 months for sensitive vegetables (lettuce, carrots), and 4) No restrictions for corn or soybean. These intervals may vary based on soil type and rainfall - clay soils require shorter intervals than sandy soils due to reduced mobility.
Q: How should Propisochlor Technical be stored for maximum shelf life?
A: Store Propisochlor Technical in its original sealed containers in a cool (5-30°C/41-86°F), dry, well-ventilated area away from direct sunlight. Keep away from food, feed, and beverages. Maintain storage areas free of ignition sources. Under these conditions, the product maintains its efficacy for 24 months from production date. If crystallization occurs, warm the container to 30-40°C (86-104°F) and mix thoroughly before use.
