Control Erwinia using bacteriophages

Bacterial diseases such as wet rot forms in recent years a rapidly growing threat to a number of important agricultural crops.

Until now, no suitable antibacterial agents are available. The use of antibiotics such as streptomycin is banned, and since then no new bactericides are allowed as plant protection products.

The aim of this project is to test the effectiveness of bacteriophages in controlling Erwinia in potato bulbs, and a better characterization of the physical and biological properties of phages. Survival and efficiency are important parameters for possible application in practice. Greenhouse, field and water heating tests show a slight protective effect of the bacteriophage against Erwinia and Dickeya
