Dyna-gro Pro-tek or Maxicrop for rose midge?
Comments (36)Dave- I haven't used it yet. CoriAnn uses it. I'll ask her. I'll let everyone know if I see any improvement to anthracnose after I foliar spray since I don't have much blackspot. I'll also see if it helps with aphids since I have these too. Patty- funny in a not funny, haha, way! I think "ironic" might be the better word. Is anthracnose as bad a disease as black spot? My roses look awful but they still have their leaves unlike with bs. And some of the Kordes are fine as is Julia and my DA Windermere and Queen of Sweden. I'm still learning. Since it doesn't cause complete defoliation I'm thinking (hoping) it might be the lesser of two evils. I haven't sprayed yet, partly out of laziness but mostly out of concern for the environment. So many of these products are harmful to aquatic life. Our property abuts a designated swamp. I'd hate to cause damage to the eco-system there. My hydrangeas and hostas look fine so it doesn't seem as bad as yours. I'll let you know when I use the Pro-tekt. With luck it just might do what it says it does. Wouldn't that be great :-) Kelp4Less has silica powder available for hydroponics. According to the info it has recently been approved asa plant nutrient recognized by science. It's helpful for those who especially grow in raised beds or pots which CoriAnn does. I have bought from Kelp4Less. They're a bit pricy but have great service and organic products. The video is a bit long but here's the link if anyone is interested- https://www.youtube.com/watch?v=YB5pBCdnMTE Dave- it seems according to the Kelp4Less is used as a drench not a foliar spray. It might be because they are geared more to hydroponics though. Their's is neutral ph. There are 9 reviews by buyers that say they see improvement in stem strength, leaf strength and disease resistance. I don't think CoriAnn gets much disease in CA where she gardens but she does get extreme heat and uses Pro-tekt for heat and drought stress. Sharon...See MoreMore rose midge advice
Comments (46)I am not an expert, but I would suggest using landscape fabric rather than plastic since it is still Permeable. Also you can cut that off and new ones will come. They're already in the soil by the time you see the burnt tip so it's not to get rid of the pupae. I have not read that spinner had helps with this insect. I think they're only 3 that help But they are systemic. If your moonlight in Paris came as a bare root, I doubt that was the source. However, I have read reports at they can over winter in canes. Still I seriously doubt that was the source Is they Is they need soil too Re generate....See MorePlastic sticky cup rose midge and thrip traps, two questions?
Comments (16)Patty, I thank you, and my new niece, May, does, too. Her first P. paniculata, I don't remember its variety, grew magnificently this year, better than any other of her new perennials. She is a young mother of two toddler girls, and an avid gardener, new to this country, coming from Thailand. May loves her 40+ young rose bushes, and learned her first, very valuable lesson the hard way this year....black spot and midge fly cannot be ignored. Early on, I supplied her with all the organic items out there, but she failed to use them. Thinking, like youth often does, that those bad things happen to other people's roses, not mine, she found out otherwise. You have been a tremendous help with your phlox recommendations, not to take precedence over all your other expert, rose enlightenments you have so generously shared with your Rose Forum friends.

Comments (31)vaporvac it is my understanding that rose midge is not new. If correct, I assume that roses have had plenty of time to develop defenses against them. Regarding your comment that midge is a sucking feeder. Here is how the immune system acts towards aphids - another sucking insect. "Author: MILES P W Author Address: WAITE AGRIC. RES. INST., UNIV. ADELAIDE, ADELAIDE, S. AUST. Title: DYNAMIC ASPECTS OF THE CHEMICAL RELATION BETWEEN THE ROSE APHID MACROSIPHUM-ROSAE AND ROSE BUDS Published in: Entomologia Experimentalis et Applicata, volumn 37, pages 129-136, (1985). Abstract: "Dynamic aspects of the chemical relation between the rose aphid [Macrosiphum rosae] and rose buds.In warm weather, M. rosae (L.) walks off buds of hybrid tea roses during a critical period coinciding with the opening of the sepals. This behavior could not be related to histologically detectable barriers to feeding, nor to changes in the water content of the tissues or in their composition with respect to total soluble carbohydrate, amino nitrogen or phenolic compounds; major changes in tissue chemistry, effected by spraying the bushes with urea, did not affect the time at which the aphids left the buds. Tissue sap expressed from stems and sepals showed a significant increase in catechin content after, rather than during, the critical period. Once expressed, however, sap from buds at the critical stage showed a sharp in vitro rise in catechin content over a few hours, up to levels approximating those against which the insects discriminated in choice tests. The insects could well be sensitive to a developing capacity of tissue to accumulated catechin, possibly in response to their feeding activity."
