About Isoproturon 50% / 75% WP
Isoproturon (50% / 75% WP) is a selective, urea-based herbicide commonly used in wheat and barley to control annual grasses, such as Phalaris minor, and broad-leaved weeds. Applied post-emergence, it works by inhibiting photosynthesis in weeds. It is typically applied at a dosage of approximately 1.33 kg/ha
- Formulation: Water-dispersible Powder (WP) at 50% or 75% concentration.
- Target Crops: Primarily wheat, barley, and rye.
- Target Weeds: Phalaris minor (littleseed canary grass), Avena fatua (wild oat), and Poa annua (annual meadowgrass).
- Mode of Action: Absorbed by roots and leaves, it inhibits electron transport in photosynthesis, causing weeds to starve.
- Application Timing: Pre-emergence or early post-emergence.
- Dosage & Dilution: For 75% WP, standard recommendation is about 1.33 kg formulated product per hectare (or gm per acre) diluted in 300750 liters of water, depending on local recommendations.
- Toxicity: Considered slightly hazardous to mammals, low toxicity to bees and birds, but can be harmful to fish.
- Compatibility: Generally compatible with other herbicides like 2,4-D and Pendimethalin.
Versatile Weed Control for Cereal CropsIsoproturon 50% / 75% WP is an ideal herbicide for wheat, barley, peas, lentils, and similar crops. By targeting both grass and broad-leaved weeds, it safeguards crop yield and helps maintain field health. Its systemic action and selective properties ensure it is effective without harming the crops when used as directed.
Reliable Formulation with Lasting Shelf LifePackaged as a wettable powder, Isoproturon offers convenient and consistent application. It maintains its efficacy for up to two years from the manufacturing date if stored correctly. The product remains stable in a wide pH range (pH 5-9), supporting flexible use across varying soil conditions.
Safe and Effective UsageWhile Isoproturon is moderately toxic to mammals, following safety protocols-such as using protective clothing-reduces risk. Its compatibility with most herbicides makes it a practical addition to integrated weed management programs, helping maximize productivity and crop safety.
FAQ's of Isoproturon 50% / 75% WP:
Q: How should Isoproturon 50% / 75% WP be applied to crops for the best results?
A: Isoproturon should be applied as a pre-emergence or post-emergence treatment using a knapsack sprayer or similar equipment. Dissolve the recommended dosage (1.0 to 1.5 kg/ha, based on crop and weed intensity) in water and spray evenly over the field to ensure thorough weed coverage.
Q: What crops can benefit from using Isoproturon WP, and why is it effective?
A: Isoproturon is designed for wheat, barley, peas, lentils, and other cereal crops. It selectively controls troublesome grass and broad-leaved weeds by inhibiting photosynthesis in the weeds, allowing the crops to grow healthier without excessive competition.
Q: When is the optimal time to use Isoproturon WP during the cropping season?
A: Isoproturon can be applied either before the emergence of weeds (pre-emergence) or after weeds have appeared (post-emergence), depending on the weed spectrum and crop stage. Early application ensures better weed management and maximizes crop yield.
Q: Where should Isoproturon be stored to maintain its potency and shelf life?
A: Store Isoproturon in its original, unopened packaging in a cool, dry place away from direct sunlight. Proper storage preserves its quality and ensures a shelf life of up to two years from the manufacturing date.
Q: What precautions should be taken when handling or applying Isoproturon WP?
A: Always wear protective clothing such as gloves and masks while handling or spraying Isoproturon. Avoid inhaling dust or spray mist, and prevent contamination of water sources, as the product is moderately toxic to mammals if swallowed.
Q: Is Isoproturon WP compatible with other herbicides or agrochemicals?
A: Yes, Isoproturon is compatible with most commonly used herbicides, making it suitable for integrated weed management programs. However, always perform a small compatibility test before large-scale mixing.
Q: What are the benefits of using a controlled release, wettable powder formulation like Isoproturon WP?
A: The controlled release formulation allows for extended activity against weeds, while the wettable powder form is easy to disperse in water, ensuring even application. This helps maintain clean fields, reduces labor costs, and supports higher yield potential in cereal crops.
