Tapir w.r.k.

Mechanism of Action and Selectivity

"Tapir WSC" is a systemic herbicide based on imazethapyr (imidazolinone group), which inhibits the synthesis of essential amino acids (valine, leucine, and isoleucine) in weeds. The primary value of this product lies in its selectivity: the active ingredient penetrates weed tissues through both foliage and the root system, rapidly translocating to the meristematic regions. This allows "Tapir" to effectively suppress both broadleaf and certain grass weeds, including quackgrass, pigweed, and common ragweed.

Technical Application Details

The water-soluble concentrate formulation ensures stability of the working solution and high penetration rates. As a selective soil-applied herbicide, "Tapir" creates a chemical barrier in the topsoil layer, preventing the emergence of new weeds such as shepherd's purse, field mustard, and barnyard grass.

• Active Ingredient: Imazethapyr.
• Mode of Action: Systemic, soil-applied, selective.
• Target Crops: Soybeans, field peas.
• Application Rate: 0.5–1.0 L/ha, one application per season.

The key feature of the product manufactured by Zhengjiang Agrin Company Ltd. is its pre-emergence application strategy. By establishing a root-zone barrier, the herbicide arrests weed development at the earliest stages, which is critical for protecting soybeans and peas during their most vulnerable growth period. Classified under hazard class 3, the product is safe to use following standard agricultural protocols, ensuring optimal weed control throughout the critical crop growth phase.
