Blackspot and Japanese Beetles
Right now my roses are all beautiful, but every year, starting in June, they
develop blackspot and are attacked by Japanese Beetles. I have garden sulfur for the blackspot,but I'm not sure how to use it. I don't want to poison any beneficial insects with it either. I know not to wet the leaves,but it does rain at night, and the leaves stay wet. As for the beetles; I try to knock them off into a jar filled with bleach or ammonia(I forget what exactly to use), but there are so many and I can't be home all the time. I doubt if there is anything that would kill or keep the beetles away without harming the bees,is there?The beetles lures aren't very effective. Would some kind person please give me some help!? Thanks. S |

Thanks. S Use mancozeb NOW every 7 days to keep away black spot. Fungicides only prevent black spot, they don't cure it. THey can stop the progression of the disease, but the damaged leaf will always remain damaged and the plant has to grow new foliage. Fungicides also do not kill insects. They are not insecticides. YOur beneficials are perfectly safe. As for Japanese beetles, Merit works splendidly. |

Blackspot and Japanese Beetles
Thanks for your advice! Is Merit an insecticide? Aren't they harmful to the
bees and similar insects? I'm desperate, so I'll probably buy it even though I try to practice organic gardening. Thanks again. Sis "Sunflower" wrote in message ... "Sis" wrote in message ...
