Another fungicide received the EPA Section 18 quarantine exemption for treatment of Asian soybean rust on soybeans. The EPA approved Stratego from Bayer CropScience for use in Minnesota and South Dakota. Other soybean-producing states are expected to grant approvals soon.
Stratego is a fungicide premix for residual control against diseases. Two active ingredients, propiconazole and trifloxystrobin, work to inhibit spore germination on the plant surface and fungal growth within plant tissues. Bayer says the product is most effective against Asian soybean rust when applied as a preventive measure.
