This year I am going to be proactive where the squash vine borer are concerned. At least I hope I’m acting in time to be proactive. I saw an adult female hanging out near the zucchini today so tonight I gave all three a Bt treatment.
It appears that the Bt Serenade fungicide is doing the trick. I had a couple of roses that had the very early stages of powdery mildew and my fig that had rust. All have had two treatments and the rust is missing from the newest fig leaves and there are no signs of PM on the roses now. I went ahead and treated my lilac (Ludwig von Spaeth) as a preventitive as it gets PM really bad every year. So far so good.
My Black Knight and Nanho Blue butterfly bushes are in bloom. This afternoon I saw a Sphingid moth on both. Not sure which species but it was the first anything that I’ve seen on the BB.
