Mode of Action:

  • Penoxsulam is a broadest spectrum herbicide for rice.

  • Penoxsulam is systemic herbicide to inhibit the acetolactate synthase, absorbed by stem, leaf, budlet, root.

  • Penoxsulam will inhibit the plant's growth, chlorosis appears on the growing point, the terminal bud will turn red in 7~14 days and necrotic, the plant will die in 2~4 weeks.

  • Long duration of 30~60 days, one off application can control the whole season's weed.

  • Penoxsulam cannot kill Leptochloa chinensis, so it can be used with Cyhalofop-butyl to control it.

  • Penoxsulam is absorbed mainly via leaves, and secondarily via roots, and is translocated in both phloem and xylem.

  • 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.

Usage of Penoxsulam:

  • Penoxsulam provides control of Echinochloa spp., as well as many broad-leaved, sedge and aquatic weeds (such as Alisma plantago-aquatica, Ammania coccinea, Cyperus difformis and Scirpus mucronatus) in rice.

  • Penoxsulam provides residual weed control, depending on soil type and use rate, and is rainfast within 1 hour of application.

  • 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.

Phytotoxicity of Penoxsulam:

  • Penoxsulam will dissolve in the soil quickly.

  • Penoxsulam is safe to rice.
