MOTOR, RC, herbicide (Bentazon – 480 g/L)

Effective Soybean Protection: Operating with MOTOR, RC

When broadleaf weeds threaten a soybean field, there is no room for experimentation. My experience with the MOTOR, RC herbicide from Shandong Weifang Rainbow has proven that it is a tool designed to solve weed problems without unnecessary stress. As a contact-action product based on bentazone (480 g/l), its selectivity is its greatest asset for the crop.

Practical Application Insights

This is a post-emergence herbicide, which defines its core utility. I typically apply it when the soybeans have emerged and the weeds are in their active growth phase, but before they start competing with the crop. Timing is critical: the smaller the weeds like ragweed, pigweed, or nightshade are at the time of application, the more effective the bentazone becomes.

• Application Rates: The rate varies from 1.5 to 3 liters per hectare. In practice, if the field is relatively clean and weed pressure is moderate, 2 liters are sufficient. However, for severe infestations of mustard or lamb's quarters, it is safer to stick to the higher end of the range.
• Contact Action: Bentazone works quickly. You will see visible signs of weed suppression within just a few days. Since this is not a systemic product that translocates through the plant for weeks, high-quality leaf coverage is essential. Do not skimp on water volume or sprayer calibration.
• Flexibility: With 1–2 applications per season, you gain full control over the field. Often, a single pass is enough if you hit the correct growth stage of the target weeds.

Operational Considerations

From an operator's perspective, I should note that the product carries a hazard class 3 rating. Standard safety protocols must be followed during handling. The soluble concentrate formulation is quite user-friendly; it mixes easily in the tank, does not form sediments, and keeps sprayer filters clean. Cleaning the equipment after use is also straightforward, as it leaves no oily residue.

For those growing soybeans, it is important to remember that MOTOR, RC is a selective tool. It does not cause crop damage if the label instructions are followed. It provides a predictable outcome for farmers who value stability and want to protect their yield without taking unnecessary risks.
