The Environmental Protection Agency has registered Kasumin bactericide to treat Erwinia amylovora, the bacteria responsible for fire blight in apples and pears.
The product is labeled for pome fruit, including pears and apples. Registration for use on other crops is pending.
Kasumin from Cary, N.C.-based Arysta LifeScience, contains the active ingredient kasugamycin, according to a news release.
The antibiotic is not registered for human uses and has shown no cross-resistance to other bactericides.
Kasumin is designed as a preventive control tool and is effective against fire blight, including those strains resistant to the antibiotic streptomycin, according to the release.
Kasumin 2L had been used in a few U.S. apple-growing states last season under a Section 18 emergency use permit to control fire blight.
The product was registered in Canada in February 2013 for use on pome fruit and in greenhouses on fruiting vegetables.
