Aspect Pro 533 SC

Reliable crop protection: Field experience with Aspect Pro 533 SC

When you start the spring season, the primary threat to sunflowers or corn is weed competition during the critical germination phase. In my experience, Aspect Pro 533 SC has proven to be the tool that allows us to ensure field cleanliness before the crops even emerge.

Operating and Efficiency Insights

Working with this pre-emergence herbicide, I immediately appreciated its systemic nature. The combination of terbuthylazine and flufenacet creates a powerful synergy: one component handles a wide spectrum of annual broad-leaved weeds, while the other effectively knocks down annual grasses. Crucially, its selectivity is top-tier — in all my seasons of applying it to corn and sunflowers, I have never observed phytotoxicity, even under challenging weather conditions.

• Application rate: I vary the dosage from 1.5 to 2.25 L/ha depending on soil type and weed density. This allows for flexible cost management.
• Control: The product effectively handles multiple flushes of weeds. Even if a dry spell occurs after application, soil moisture activation ensures the barrier remains effective.
• Ease of use: The suspension concentrate formulation is a relief for operators. It mixes perfectly in tank mixtures, doesn't clog sprayer filters, and ensures easy nozzle cleaning.

Practical Tips for Field Operations

To achieve the best results, remember that Aspect Pro is a pre-emergence herbicide. It is best applied immediately after planting. One application per season is more than enough to handle weed pressure at the starting stage. We always follow the safety instructions (Hazard Class 3). Remember that effectiveness is highly dependent on seedbed quality and field uniformity, so proper tillage is half the success when using this herbicide from Bayer.
