1 CAUTION: FIRE BLIGHT. The conditions favorable for fire blight include all of the following: (1) open blossoms and succulent young growth; (2) a temperature of 65F or higher; and (3) rainfall, or a relative humidity of 60% or higher. Apply the first streptomycin spray just before the earliest blossoms open and repeat at 5-day intervals until petals on latest blossoms have fallen. If streptomycin is applied alone, the rate may be reduced to 60 ppm (5 oz/100 gal dilute; 15 oz/A concentrate). The effectiveness of streptomycin can be increased by including the adjuvant Regulaid at the rate of 1 pint per 100 gal of tank mix. Apply streptomycin in at least 50 gallons of water per acre.

2 Do not apply more than 60 fl oz per acre per year. Do not apply more than two sequential applications before rotating to a different mode of action and no more than four

1 Pyrethroids may be applied no more than twice during the prebloom period. Monitor ERM closely postbloom because these products are highly toxic to predators of ERM.

2 Apply only once per season, when eggs or young mites are present.
