BASF's soybean fungicide Priaxor D will be used to control strobilurin-resistant frogeye leaf spot

BASF's soy fungicide Priaxor D has received federal Environmental Protection Agency registration, the company said Tuesday.

A combination fungicide containing three modes of action, Priaxor D fungicide helps manage strobilurin-resistant frogeye leaf spot in soybeans while providing increased growth efficiency and stress tolerance, BASF said.

"Strobilurin-resistant frogeye leaf spot is a major concern for growers, specifically in the Mid-South," said Megan Andriankaja, Ph.D., technical market specialist with BASF. "We are excited to introduce Priaxor D fungicide, the first three mode of action fungicide for soybean growers."

Priaxor D fungicide is a combination of F500 and Xemium fungicide, the same active ingredients as in Priaxor fungicide, combined with tetraconazole.

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.

"The first step to managing strobilurin-resistant frogeye leaf spot is to plant a soybean variety that is resistant to the disease," Andriankaja said. "When resistant soybean varieties are planted in low-risk areas of resistance, BASF recommends a proactive application of Priaxor fungicide."

State registrations for Priaxor D fungicide are expected in time for the 2015 growing season, BASF said.
