AgriPhage™- Fireblight

(Erwinia amylovora) 

AgriPhage™ Fireblight is a bacteriophage (virus) which attacks Erwinia amylovora on apples and pears. This product can be used in organic orchards under the USDA National Organic Program but can also be used to enhance the performance of conventional tactics in orchards as a preventative or curative measure.
