Grainuron, WG (tribenuron-methyl, 750 g/kg)

Technical Efficiency of Grainuron WG

The core of Grainuron WG is tribenuron-methyl at a concentration of 750 g/kg, formulated as water-dispersible granules. This specific formulation is designed to ensure superior dispersibility in spray tanks, preventing clogging and ensuring uniform delivery across the field. Being a systemic herbicide, it enters the plant through the leaf surface and moves rapidly through the phloem and xylem, effectively targeting the plant's metabolic pathways.

Selective Weed Control

Grainuron inhibits the acetolactate synthase (ALS) enzyme, which is vital for weed cell division. This mechanism makes it a highly effective selective tool for wheat (winter and spring) and winter barley. It provides robust control over challenging broadleaf weeds including common ragweed, catchweed bedstraw, white mustard, shepherd's purse, and field thistle. Its systemic nature allows it to stop weed competition almost immediately after application.

• Action Type: Post-emergence, selective, systemic herbicide.
• Application Rate: 0.015–0.05 kg/ha, depending on weed development stage.
• Manufacturing Quality: Produced by specialized Chinese chemical enterprises, including Nanjing Red Sun Co., Ltd. and Jiangsu Golden Chemical Co., Ltd.

Practical Application Insights

To maximize the efficacy of this herbicide, application should occur during the active growth phase of weeds, typically when they are in the 2-4 leaf stage. The product’s 3rd hazard class profile makes it a manageable solution for large-scale operations. Since only one application per season is permitted, timing is critical to ensure that the active ingredient is applied when the target weeds are most vulnerable. By eliminating weed pressure early in the season, Grainuron helps to conserve soil moisture and nutrients specifically for the cereal crop, securing the yield potential.
