copper _&_ chlorothalanil _&_ streptomycin fall spray ?
Just getting my head around to thinking about preparing for fall/winter dormant spray.
I order to control leaf curl, fire blight etc,-
1). Is there any benefit to using _all three_; copper AND chlorothalanil AND streptomycin dormant spray (together or as separate sprays) this fall?
2). If yes how much time between sprays?
3). Any downside?
