Feb. 3, 2015 — Priaxor D fungicide from BASF has received federal EPA registration.
A combination fungicide containing three modes of action, Priaxor D fungicide helps manage strobilurin-resistant frogeye leaf spot in soybeans while providing Advanced Plant Health benefits, including increased growth efficiency and stress tolerance.
Priaxor D fungicide will be a much-needed option for growers in states experiencing high levels of strobilurin-resistant frogeye leaf spot, including Arkansas, Kentucky, Louisiana, Mississippi and Tennessee.
Priaxor D fungicide is a combination of F500 and Xemium fungicide, the same active ingredients as in Priaxor fungicide, combined with tetraconazole. The combination of these active ingredients can further increase the control of strobilurin-resistant frogeye leaf spot in soybeans.
In Mid-South field trials, soybean acres treated with Priaxor D fungicide had a 1.8 severity of strobilurin-resistant frogeye leaf spot on a 10-point scale. Acres treated with Priaxor fungicide alone experienced a 3.5 disease severity. The untreated check experienced 7.0 disease severity, demonstrating the need to use an effective triazole to control strobilurin-resistant frogeye leaf spot.
“The first step to managing strobilurin-resistant frogeye leaf spot is to plant a soybean variety that is resistant to the disease,” says Andriankaja. “When resistant soybean varieties are planted in low-risk areas of resistance, BASF recommends a proactive application of Priaxor fungicide. In addition to controlling frogeye leaf spot, Priaxor fungicide controls other diseases, including Septoria brown spot, anthracnose and aerial web blight.”
When a susceptible soybean variety is planted and strobilurin-resistant frogeye leaf spot is suspected or confirmed in the region, BASF recommends an application of Priaxor D fungicide. An application of Priaxor D fungicide provides excellent control of disease, including strobilurin-resistant frogeye leaf spot, while providing advanced plant health benefits.
State registrations for Priaxor D fungicide are expected in time for the 2015 growing season. Contact your local authorized BASF retailer or BASF representative for more information on Priaxor D fungicide.
