Rassell 100 SC

Mode of Action: Florasulam, the active ingredient in Rassell 100 SC, belongs to the triazolopyrimidine group and works by inhibiting the acetolactate synthase (ALS) enzyme, which is essential for the synthesis of branched-chain amino acids. The product is absorbed through the leaves of weeds and rapidly translocated throughout the plant, stopping protein synthesis and causing growth inhibition.

Under optimal conditions (warm and humid weather), total weed destruction occurs within 7-10 days, while at lower temperatures (around 4°C), it may take up to 3 weeks. The product is most effective when weeds are in the 2-6 leaf stage.

  • Application timing: From the tillering stage until the first internode stage (BBCH 24-31). Weeds should be in the 2-6 leaf stage.

• Winter Barley and Rye:

  • Dosage: 50 mL/ha
  • Application timing: In autumn, from the 1-leaf stage until the 7-tiller stage (BBCH 11-27). Weeds should be in the 2-6 leaf stage.

• Corn:

  • Dosage: 50 mL/ha
