Penoxsulam TC

Penoxsulam, is a trizolo pyrimidine herbicide applied in paddy fields with the widest herbicidal spectrum. It has a great effect not only in aquatic weeds control but also in barnyard grass which has resistance to herbicides like quinclorac, propanil, and sulfonylurea. With aquatic weeds’ higher resistance, penoxsulam plays a more vital part in weeds control.

Detailed information:

  • Common name: Penoxsulam
  • IUPAC name: 3-(2,2-difluoroethoxy)-N-(5,8-dimethoxy[1,2,4]triazolo[1,5-c]pyrimidin-2-yl)-a,a,a-trifluorotoluene-2-sulfonamide
  • CAS No.: 219714-96-2
  • Molecular formula: C16H14F5N5O5S
  • Molecular weight: 483.4
  • State: Off-white solid with a musty odour.
  • Packing: 25kg (providing additional packing as required)
  • Mode of action: Absorbed via leaves, stems and roots. Symptoms include almost immediate growth inhibition, a chlorotic growing point with necrosis of the terminal bud, resulting in plant death in 2 to 4 weeks. Applied pre-emergence, post-emergence and water-applied.
  • Application: Provides control of Echinochloa spp., as well as many broadleaf, sedge and aquatic weeds in rice. Penoxsulam provides residual weed control, depending on soil type and use rate.
    In tropical rice, application will be at 10-15 g/ha; in temperate rice, 20-50 g/ha. Primary use will be a post-emergence application in dry-seeded, water-seeded and transplanted rice.
