What are the significant changes in the Section 3 label from the Section 18 label?
- Kasumin 2L can be used throughout Michigan, i.e., use is not restricted to counties with streptomycin resistance.
- Kasumin 2L can now be used on pears as well as apples.
- There is no longer a requirement for state experts to indicate potential epidemic conditions for fire blight prior to an application. However, I strongly suggest that growers continue to use the fire blight disease prediction model available on the MSU Enviro-weather website and only apply Kasumin when predicted EIP values are 100 or greater.
- Do not apply Kasumin in orchards in which the soil has been fertilized with animal manure.
- Do not apply after petal fall.
- Do not use alternate row applications.
- The use rate is 64 fluid ounces (2 quarts) per acre. Using 64 fluid ounces in 100 gallons of water is optimal; reduced spray volumes can be used for smaller trees.
- Do not apply after petal fall. There is also a 90-day pre-harvest interval (PHI).
- A maximum of four applications can be made. I strongly suggest not applying more than three applications per season for resistance management purposes.
