Prometryn 50% SC Herbicide

Prometryn 50% SC Herbicide – Selective Weed Control for Cotton and Broadleaf Weeds

Prometryn is a selective triazine herbicide designed to deliver effective control of annual broadleaf weeds and certain annual grasses in cotton, vegetables, and other approved crops. Its primary mode of action as a Photosystem II inhibitor disrupts weed photosynthesis, leading to yellowing, leaf scorch, and eventual plant death.

Your growers benefit from Prometryn 50% SC (Suspension Concentrate) because this formulation ensures excellent stability, uniform suspension, and easy handling in large-scale field operations. Compared to older wettable powder forms, the SC type reduces dust during mixing and improves application safety for farm workers.

With good soil residual activity, Prometryn remains active for several weeks, suppressing new flushes of sensitive weeds during critical crop establishment stages. This helps your customers reduce manual weeding costs and maintain clean fields with fewer repeat sprays.

Prometryn herbicide works well in pre-emergence or early post-emergence programs, giving your buyers flexibility to adapt to local weed pressure and seasonal weather conditions. When integrated into a broader weed management plan, it can be tank mixed with other compatible herbicides to expand the weed spectrum and delay resistance.

When you supply Prometryn 50% SC, you deliver more than just a product — you provide your customers with a practical, reliable tool for protecting yield, lowering input costs, and staying competitive in demanding cotton markets.

Mode of Action

Prometryn herbicide works as a selective Photosystem II inhibitor, part of the triazine chemical family. Once applied, it is absorbed primarily through the roots and emerging shoots of weeds, then translocated throughout the plant to the leaves where it disrupts the normal photosynthetic process.

Prometryn blocks electron transfer within Photosystem II, stopping the conversion of light energy into chemical energy. This leads to the accumulation of toxic by-products inside the plant’s cells, causing leaf chlorosis, scorching, wilting, and ultimately complete weed death.

Your growers benefit because this mode of action provides both pre-emergence and early post-emergence control of annual broadleaf weeds and some annual grasses, making it a flexible choice for different weed pressures and weather conditions.

Because Prometryn 50% SC remains active in the soil for several weeks, it continues to suppress new weed seedlings during critical crop stages, giving cotton and other approved crops a stronger competitive advantage.

When used alone or as part of a tank mix with other herbicides, Prometryn supports integrated weed management (IWM) strategies that help reduce labor, extend residual control, and delay the buildup of resistant weed populations.
