Information on agricultural streptomycin, please.  Agricultural streptomycin was at one time widely used effectively on bacterial diseases in many plants.

It is now reserved mainly for control of fire blight on pears. The reason for the decreased use is that there is a possibility that the streptomycin might buildup in the human body. The concern was that when streptomycin was needed for medical purposes, the body would have a resistance built up and the medical streptomycin would not be as affective.

In place of the agricultural streptomycin, fixed coppers should be considered.
