Tribenuron Methyl Herbicide – Selective Post-Emergence Control for Broadleaf Weeds

Tribenuron-methyl is a highly active sulfonylurea herbicide used primarily for post-emergence control of broadleaf weeds in cereal crops. It is classified as a systemic, selective herbicide, designed to inhibit the growth of sensitive weeds by interfering with their essential enzymatic pathways.

Приналежність до ALS (acetolactate synthase) inhibitor group, tribenuron-methyl disrupts the biosynthesis of branched-chain amino acids (valine, leucine, and isoleucine), which are crucial for cell division and growth. This leads to rapid inhibition of weed development shortly after application, typically with visible symptoms such as chlorosis and necrosis within 5 to 10 days.

It is widely recognized for its high efficacy at low use rates, rapid degradation in soil та crop safety in cereals like wheat and barley. It also shows favorable environmental properties, including low volatility and reduced leaching potential under standard field conditions.

Mode of Action & Selectivity

Tribenuron-methyl works by inhibiting the enzyme ацетолактатсинтаза (АЛС), a key catalyst in the biosynthesis of branched-chain amino acids essential for plant cell division and growth. Once absorbed through the foliage, the active ingredient translocates via the phloem to meristematic tissues, where it effectively halts cell division in sensitive broadleaf weeds.

Цей systemic, post-emergence herbicide is remarkably selective due to its unique metabolic pathways in crops versus target weeds. Cereal crops such as wheat and barley can metabolize tribenuron-methyl quickly into non-toxic byproducts, while broadleaf weeds lack this capacity and are therefore highly susceptible.

Visible effects such as chlorosis and stunted growth typically appear within days, followed by necrosis and complete control within 1–3 weeks depending on weed species and environmental conditions.

Formulations & Technical Specifications

Tribenuron-methyl is available in versatile formulations to suit various crop protection programs, with technical specifications that meet international quality and registration standards.

The most commonly supplied forms include Tribenuron-methyl 75% WDG (water dispersible granules) та Tribenuron-methyl 10% WP (wettable powder). These formulations are designed for ease of use, rapid dispersion, and consistent field performance, making them ideal for both small-scale farms and large commercial operations.

The active ingredient has a Номер CAS 101200-48-0, то molecular formula of C15H17N5O6S, and functions as a Group 2 ALS-inhibitor herbicide. It is characterized by low use rates (typically 15–30g/ha), which contribute to reduced packaging waste and favorable logistics.

All POMAIS products conform to FAO quality standards and can be produced with customizable moisture content, particle size, and wetting agents based on your market registration needs.

Target Weeds & Crops

Tribenuron-methyl delivers highly effective control of a wide range of broadleaf weeds while maintaining excellent crop selectivity in cereals and other rotational crops.

It is particularly effective against key weed species such as chickweed (Stellaria media), cleavers (Galium aparine), shepherd’s purse (Capsella bursa-pastoris), wild mustard (Sinapis arvensis), field pennycress (Thlaspi arvense), pigweed (Amaranthus spp.), henbit та common lambsquarters (Chenopodium album). These are often troublesome in winter and spring cereals, especially in wheat, barley, and oats.

This herbicide is ideally suited for use in wheat, barley, oat, rye та тритикале, and its favorable rotational profile also supports follow-up crops such as corn, soybeans, potatoes, flax, and sunflower. Its ability to act early in the weed lifecycle helps minimize competition during critical crop growth stages, leading to better yield potential and cleaner fields.

By targeting broadleaf weeds at the cotyledon to 4-leaf stage, Tribenuron-methyl achieves rapid growth inhibition and visible symptoms like chlorosis and necrosis within days of application.

Способи застосування та дозування

Tribenuron-methyl is typically applied as a post-emergence foliar spray, allowing it to effectively target actively growing broadleaf weeds without harming cereal crops.

It is best used between the 2- to 6-leaf stage of the crop and when the target weeds are in the cotyledon to 4-leaf growth stages. Applying during optimal weed size maximizes uptake and translocation, ensuring strong herbicidal activity and minimal regrowth.
