biofungicides and rain
I'm wondering if I should spray my tomatoes with Serenade tomorrow with a heavy rain forecast that night, or wait until after the storm?
Will the rain wash the bacteria off the leaves or can the colonies hang on? I have not been spraying when rain is forecast, but now I'm wondering if that's been a mistake, especially considering that my tomatoes suffer an explosion of spotty leaves after each storm.
Also, I just sprayed Actinovate yesterday/today - will following with Serenade so closely interfere, or do the different species of bacteria coexist peacefully? I've been trying to spray the tomatoes every 3-4 days alternating between the two products, so that they get both on a weekly basis, but it was rainy on Wed so my Actinovate spray was delayed. (and I pulled a 5 gallon bucket of spotty leaves out after the rain.)
Thanks for any insight into proper biofungicide use :)
