Rex Duo

Reliable protection for cereals and sugar beets: handling Rex Duo

When it comes to crop protection, every agronomist looks for a solution that delivers results where it counts: in the field. Rex Duo from BASF has become a staple in my operations for managing health in winter wheat, barley, and fodder beets. By combining two distinct active ingredients—epoxiconazole and thiophanate-methyl—it provides a robust systemic defense that halts fungal pathogens in their tracks.

Application and Field Performance

One thing I appreciate as an operator is how user-friendly this formulation is. The suspension concentrate mixes easily into the tank, shows great compatibility, and doesn't clog nozzles during spraying. We primarily use it to combat root rots, helminthosporiosis, and various leaf spots. In barley, it has been particularly effective against net blotch.

• Application rate: We typically range from 0.5 to 1.0 L/ha, adjusting based on the disease pressure and environmental conditions.
• Treatment limit: A maximum of two treatments per season is usually sufficient to maintain a strong defensive barrier.
• Pre-harvest interval: We adhere to the 20-day requirement before harvesting, which fits perfectly into our seasonal planning.

A Practical Perspective

Efficiency is key, and Rex Duo offers a long-lasting protective effect. Because of its systemic action, it is absorbed quickly and translocated through the plant tissue, protecting new growth even after application. This longevity is crucial for grain filling, ensuring that the crop reaches its full yield potential without being hindered by late-season fungal development. While it falls under the 3rd hazard class requiring standard protective gear, the reliability of the disease control makes it a highly effective tool for any intensive farming setup.
