Thiobencarb 50% EC

Thiobencarb 50% EC (common trade names: Saturn, Benthiocarb) is a selective, systemic herbicide formulated as an emulsifiable concentrate. It targets grass and broadleaf weeds in rice and other crops through root and shoot absorption, disrupting cell division. Known for its low mammalian toxicity and environmental safety, it is widely used in integrated weed management systems

Key Technical Specifications

Target Weeds & Application Rates

Primary Controlled Weeds:

Grasses: Barnyard grass (Echinochloa crus-galli), Crabgrass (Digitaria spp.), Foxtail (Setaria spp.).
Sedges: Smallflower umbrella sedge (Cyperus difformis), Rice flatsedge (Cyperus iria).
Broadleaves: Purslane (Portulaca oleracea), Chickweed (Stellaria media).

Application Guidelines:

Crop	Dosage (L/ha)	Method	Timing
Rice (Paddy)	1.5–2.0	Soil incorporation	Pre-emergence (before weed germination)
Wheat	1.0–1.5	Soil spray	Post-sowing, pre-emergence
Vegetables	1.2–1.8	Soil drenching	Transplanting stage

Safety & Environmental Profile

Ecotoxicity: Low risk to birds; moderate toxicity to fish – avoid direct contamination of water bodies.
Crop Safety: Safe for rice seedlings when applied pre-emergence; avoid use in waterlogged fields.
Re-entry Interval: 24 hours after application.
Buffer Zones: Maintain 10m from aquaculture areas.

Advantages & Limitations

Advantages:
✅ Broad-spectrum control: Suppresses >20 weed species.
✅ Low residue: Degrades rapidly in soil (DT₅₀: 7–10 days).
✅ Cost-effective: Reduces manual weeding labor by 70%.

Limitations:
⚠️ Not effective against established weeds (>3-leaf stage).
⚠️ Avoid flooded rice fields – may reduce efficacy.

Compatibility & Mixing

Tank-Mix Partners: Compatible with bensulfuron-methyl (for broader sedge control) or 2,4-D (broadleaf enhancement).
Incompatible Products: Do not mix with copper-based fungicides.
