Rinskor active technology and complementary dual modes of action
Novlect brings together two distinct chemical classes to deliver cross-spectrum weed control while tackling herbicide resistance.
- Florpyrauxifen-benzyl (Rinskor active, HRAC Group 4): An arylpicolinate synthetic auxin disrupting plant hormone balance in broadleaf weeds and sedges.
- Cyhalofop-butyl (HRAC Group 1): Inhibits acetyl-CoA carboxylase (ACCase), blocking fatty acid synthesis in grassy weeds.
- High physiological selectivity: Rice plants metabolize and detoxify both active molecules without suffering stunting or leaf injury.
- Emulsifiable concentrate (EC) formulation: Ensures rapid foliar absorption and rainfastness within a few hours of application.
Target weed flora in transplanted and direct-seeded rice
Novlect is engineered to handle complex mixed weed flushes in both direct-seeded rice (DSR) and puddled transplanted paddy.
- Grassy weeds: Echinochloa colona, Echinochloa crus-galli (barnyard grass), and Leptochloa chinensis (sprangletop).
- Broadleaf weeds: Ludwigia octovalvis, Sphenoclea zeylanica, and Eclipta prostrata.
- Sedges: Cyperus difformis, Cyperus iria, and Scirpus species.
- Residual suppression: Eliminates early weed competition, allowing rice tillers to establish a dense, productive canopy.
Application timing, water management, and spraying guidelines
Apply Novlect when target weeds are in the 2 to 4 leaf stage and actively growing. Drain standing field water prior to spraying so weed foliage is exposed to the spray mist. Reintroduce irrigation water into the paddy field within 24 to 48 hours following application and maintain shallow water depth to prevent subsequent weed germination. Use flat fan nozzles with calibrated water volumes.

Common questions
What are the active ingredients in Novlect herbicide?
Novlect contains Florpyrauxifen-benzyl 2.13% (Rinskor active) and Cyhalofop-butyl 10.64% w/w in an EC formulation.
Why is Novlect especially valuable for Direct-Seeded Rice (DSR)?
DSR fields suffer aggressive simultaneous flushes of grasses, broadleaves, and sedges; Novlect controls all three weed classes in a single post-emergence spray.
How should field water be managed when applying Novlect?
Drain standing water before application so weeds are fully exposed, then re-flood the field 24 to 48 hours later to maintain weed suppression.
