About Isoproturon 50% / 75% WP
Isoproturon 75% WP is a urea based herbicide. It is a selective post emergent herbicide. Is used typically, in cereals to control annual grasses and many broad-leaved weeds. It is used to control Phalaris minor, Avena fatua, Poa annua pests on wheat.

Isoproturon is non-persistent in soil; very photochemically stable, and stable to acids and alkalis,[1] but under sustained ultraviolet light can degrade into some eleven products,[5] and can be hydrolytically cleaved by strong bases on heating.[1]
Degradation is mainly N-demethylation and oxidation of the ring-isopropyl group. Variations in order give rise to a few possible pathways, and the balance of demethylation and oxidation can allow selective activity of the herbicide. Both reactions may occur, making a typical degradation product of 2-(4-Aminophenyl)propan-2-ol (also called Dimethyl-p-Aminobenzylalkohol),[5] which is an irritant and may be harmful if swallowed.[18]
Most isoproturon is expected to have degraded in soil after 6-28 days; the rate is temperature sensitive as the process is driven by enzymes and microbes.[1] In water, the DT50 is 40 days, and in water sediments 149 days.[7]
Metabolism in plants usually follows the path beginning with isopropyl side chain oxidation.[5] White-rot fungus has the lignin-degrading enzymes lignin peroxidase and manganese peroxidase which are known to degrade
Systemic Action for Comprehensive Weed ControlIsoproturon WP operates systemically, moving through plant tissues after absorption via roots and shoots. By inhibiting photosynthesis, it effectively eliminates unwanted grasses and broadleaf weeds, ensuring crops grow with minimal competition. This targeted mode of action helps protect yields from the early stages of growth.
Flexible Application and CompatibilityWith its dispersible wettable powder formulation, Isoproturon is simple to apply using standard spraying equipment. Available in a range of packaging sizes from 250 g to bulk, it suits small and large operations alike. It is compatible with widely used herbicides, enabling integrated weed management strategies without compromising effectiveness.
Safe Usage and LongevityAs a Class III (slightly hazardous) product, Isoproturon WP should be handled using recommended safety measures. Stored in a cool, dry place, it maintains its efficacy for at least two years. Its controlled release ensures prolonged protection, and the pH range (6.0-8.0) aligns with most agricultural water sources for easy mixing.
FAQ's of Isoproturon 50% / 75% WP:
Q: How should Isoproturon 50%/75% WP be applied for optimal results?
A: Isoproturon WP should be applied as a pre- or post-emergence herbicide, using water for dispersal and standard field spraying equipment. It is essential to follow the recommended dosage of 1.0-1.5 kg/ha, depending on the weed spectrum and field conditions, to achieve the most effective weed control.
Q: What types of weeds does Isoproturon WP effectively target?
A: This herbicide is designed to control a broad range of annual grasses and broadleaf weeds, making it ideal for crops that are susceptible to competition from these unwanted plants.
Q: When is the best time to use Isoproturon WP for weed management?
A: Isoproturon WP can be applied both pre-emergence (before weeds emerge) and post-emergence (after weeds appear), allowing for flexibility based on specific field situations and weed growth stages.
Q: Where should Isoproturon WP be stored to maintain its shelf life?
A: For maximum shelf life of at least two years, Isoproturon WP should be stored in a cool, dry place away from direct sunlight and moisture. Proper storage conditions help preserve its effectiveness and safety.
Q: What is the process for preparing and applying Isoproturon WP?
A: Dissolve the required quantity of Isoproturon WP in a small amount of water to form a slurry, then dilute to the final spray volume. Stir or agitate the mixture thoroughly before and during application to ensure even distribution of the herbicide.
Q: How does Isoproturon WP benefit farmers and crop yield?
A: By effectively controlling weeds during critical crop growth periods, Isoproturon WP reduces competition for nutrients, light, and water. This results in healthier crops and improved yields, offering farmers a reliable solution for weed management.
Q: Is Isoproturon WP safe to use with other herbicides?
A: Yes, Isoproturon WP is compatible with most major herbicides, making it easy to integrate into existing weed management programs without reducing its efficacy.
