Protezhe, RC, (Bentazon, 560 g

Mechanism of Action and Selectivity

"Protege" is a specialized contact herbicide featuring bentazone at a concentration of 560 g/L. Unlike systemic formulations that translocate through the plant's vascular system, bentazone acts directly on the photosynthetic apparatus of weeds. Upon contact with the leaf surface, the active ingredient interrupts the electron transport chain in Photosystem II, causing rapid cessation of photosynthesis and subsequent plant necrosis.

Why This Formulation Matters

The benzothiadiazinone class, to which bentazone belongs, is renowned for its high selectivity. Crops such as soybeans, cereals, flax, and peas possess internal mechanisms to metabolize the active ingredient into inactive compounds, ensuring crop safety. Conversely, susceptible broadleaf weeds—such as lambsquarters, pigweed, field mustard, and chickweed—lack these protective enzymes, leading to rapid weed control. This makes "Protege" a critical post-emergence tool for critical growth windows.

Technical Application Guidelines

• Formulation: As a Soluble Concentrate (SL), the product ensures rapid dissolution in water, preventing nozzle clogging and promoting uniform droplet distribution on target leaf surfaces.
• Contact Action: Since the herbicide does not move systemically through the soil, spray coverage is paramount. Application rates range from 1.5 to 3 L/ha depending on weed density and growth stage.
• Operational Protocol: Up to two applications are permitted per season. With a 30-day pre-harvest interval, it fits seamlessly into standard weed management programs for pulses and cereals.

Manufactured by Jiangsu AgroChem Laboratory Co., Ltd., "Protege" provides targeted, selective control. Because it is a contact herbicide without significant residual soil activity, success depends on proper timing—targeting young, actively growing weeds ensures maximum efficiency while minimizing competitive stress on the crop.
