Re: Re: rose/crab apple rust and Japanese Beetles


Hi Marya,

Thanks for the advise on the mildew spots.  It does sound like that is what 
I might have on my roses. By the end of the season the leaves have just 
about all dropped off.  How long does this treatment last?  When we used to 
treat our crab apple trees it said that they had to be treated after every 
rain.  Is this the same concept for the roses?  Also, since you put some 
dishwashing liquid in the solution does this help keep the bugs off the 
plants as well?

Mary
