ENDURA (GROUP 7)
This is definitely the best product, and it’s labeled in many crops. The problem is it costs over $30 per acre. Where we see this fitting well is if you have bad fields or bad areas within fields that can be spottreated using a variable rate map to shut the sprayer on and off. If you are going to use Endura, the timing we prefer is early. In soybeans, for example, that’s R1 (first flower) and definitely before you see any white mold in the field.
PROLINE (GROUP 3)
This is the best triazole for white mold. If you are in the Bayer Plus program, you could pay as little as $8 for the 5 ounce soybean rate on a net basis. In dry beans, use 5.7 ounces per acre.
TALARIS (GROUP 1) + ANDIAMO (GROUP 3)
Combining the active ingredients found in Topsin and Domark respectively, this is my favorite two-way combo because it’s cheap and fairly effective. Use the full rate of each – 20 ounces of Talaris plus 5 ounces of Andiamo – for a total cost of around $13. To get the same active ingredients in a premix, you can use Acropolis.
APROACH (GROUP 11)
I still have farmers who tell me they have liked this product, but I’ve never seen it do much to white mold. I would not recommend it, in part because it’s expensive, but I don’t like any of the strobilurin products for this disease.
