Smith

Professional Weed Control for Grain Crops

The herbicide "Smit" by "China Chemical Industrial and Research Co. Ltd." is a highly selective post-emergence solution designed to protect winter wheat, barley, and corn. Based on thifensulfuron-methyl, a sulfonylurea derivative, this systemic herbicide ensures the effective elimination of broadleaf weeds without impacting crop development.

Field Application and Strategy

"Smit" is a foliar-applied herbicide that acts systemically, translocating through the plant tissue to inhibit cell division in weeds. This mechanism ensures that difficult-to-control species such as Cirsium arvense, Chenopodium album, Convolvulus arvensis, and Amaranthus retroflexus stop growing shortly after application. Complete weed mortality is typically observed within one to two weeks.

• Crops: Winter wheat, winter barley, corn.
• Target Weeds: Field thistle, lambsquarters, bindweed, pigweed, field mustard, wild radish, shepherd's purse, and common chickweed.
• Usage Rate: Up to 25 grams per hectare.
• Formulation: Water-soluble granules (WG) for easy mixing and precise application.

Farmers utilize "Smit" for its high efficiency and short pre-harvest interval—only 1 day until entry into the field is permitted. This allows for optimal operational flexibility during the busy spraying season. Classified under toxicity level 3, the product is predictable and manageable when standard safety protocols are followed. With a single application, it effectively clears the competition, ensuring the crop receives maximum access to nutrients and water during critical growth stages.
