Bentazone 480g/L SL Herbicide

Broad-Spectrum, Post-Emergence Weed Control Solution for Professional Growers

Bentazone 480g/L SL is a highly effective, post-emergence contact herbicide formulated for the selective control of broadleaf weeds and sedges across a variety of crops including soybeans, rice, peanuts, peas, corn, and alfalfa. As a Photosystem II inhibitor, it halts photosynthesis in target weeds, causing visible chlorosis and necrosis within days—leading to rapid, reliable weed death.

Application Guidelines

Crop	Target Weeds	Timing	Dosage (L/ha)	Method
Soybeans	Broadleaf weeds, sedges	Post-emergence (2–5 leaf stage)	1.0–2.5	Foliar spray
Rice	Broadleaf weeds, sedges	Post-emergence (3–6 leaf stage)	1.2–2.0	Foliar spray
Peanuts	Pigweed, chickweed	Post-emergence (early weed stage)	1.0–2.0	Foliar spray
Corn	Broadleaf weeds	Post-emergence (up to 4-leaf stage)	1.0–2.5	Foliar spray
Alfalfa	Broadleaf weeds	Actively growing weeds (post-emergence)	1.2–2.0	Foliar spray

Water Volume: 150–300 L/ha
Rainfastness: 4–6 hours after application
Soil Half-Life: 12–25 days (microbial degradation)

Mode of Action

Bentazone 480 SL inhibits Photosystem II in plant cells, blocking the electron transport chain in chloroplasts. This disruption halts photosynthesis, causing:

Chlorosis (yellowing)
Desiccation (drying)
Necrosis (cell death)
Weed control within 5–10 days

As a contact herbicide, it acts primarily through leaf absorption and is non-systemic, emphasizing the importance of thorough spray coverage.

Tank Mix Compatibility

Bentazone 480g/L SL can be tank-mixed with most herbicides except those with highly acidic or alkaline pH. Common combinations include:

Bentazone + MCPA – Broadleaf control in cereals
Bentazone + Clodinafop – Broadleaf + grass weed control
Bentazone + Quizalofop – Ideal for soybeans
