These small yellow things have covered up my currant on the underside of the leaves. I assume they're eggs of some kind but can anyone tell me what kind? Thanks
I was thinking of a systemic fungicide because the fungus gets inside between the plant cells and takes over the nutrient supply. That makes it tough. Some of the white papers I read spoke of neem oil as relatively ineffective, but only in the context of neem being a commonly referred remedy. There are other oils that are more aggressive for garden variety fungus such as thyme and garlic oils. I imagine that somewhere, somebody has tested them agains rust as rust is a agricultural pathogen for some crops, even tree crops. But back to the idea of eating from the plant, I saw a suggesstion of using Serenade, a biological bacterial control called bacillus subtilis, not to be confused with the insecticide bT. There are products like actinovate (streptomycin) and mycostop (also streptomycin but different strain). This is a good idea, where you hire some bio-thugs to eat the rust fungi. There is cornmeal, which will attract that greenish grey mold called trichoderma. Tricho eats everything but does not hurt the plant. How to get it up the leaves is my question, but once on scene it is potent. Maybe use them all. You need very little, as there are billions of live particles in the smallest pinch of these type products.Probably won't eat from it anytime soon. It's a young plant so hardly any fruit on it at the moment
Interesting link! I'm in Southern California so white pine isn't really a concern, but I'm always interested in those sorts of interactions
