Rose Midge - Can we share our strategies pls?
Comments (107)Jim I have been racking my mind over your roses. You have 2 of my finest roses and it makes me mad that they won't grow for you. In all my years theres one thing I know for sure midge hates dry. A couple of years ago that is exactly what I did after bringing home some midge infested plants from Chicago. It does work to let the soil dry and will kill the midge the only trick is not to bring midge back into the garden again. We are having one of the driest year on record here. The midge are not smiling nor biting my roses. I'm certain that many have been killed off. Not all of them thou because I have had to water to keep things alive....See MoreSoaking rose bands in water bucket for insect control, esp. rose midge
Comments (35)Thanks Patty and Rebecca. Dynatrap! Dang that auto-correct!! I did search on Amazon but couldn't find one that had the amount of blue like yours does. I wonder if it makes a difference? I think other commenters thought that the blue would attract thrips and midges-then Zap!! A bit pricey when there are roses to buy ;-) but worth it. We have dogs and heart worm is very prevalent here. Actually two of our past dogs were diagnosed and treated for it. Plus we have Eastern Equine Encephalitis here to worry about as well as West Nile Virus. And now a new deer tick illness that has killed, I believe, 8 people in Massachusetts. And we thought lyme disease was bad enough. Some of the beneficial nematodes, Nemaseek being one, list ticks as a target insect so I'll be purchasing some in the spring since I read summersrythm's post that said they need over 45 temps to survive. mad- So the little suckers don't drown? I would think the eggs would be encapsulated somehow though to protect against drowning like a chicken egg. Would the go into a kind of suspended animation and not hatch until the conditions are favorable? There's just so little info available on detailed rose midge life cycle. How do you handle new spring rose purchases? No killing frosts at that point. Would a quarantine work? If so, for how long to break the cycle? Do rose midge breed and reproduce from spring through frost? And I thought the monthlong assault of Japanese beetles was bad enough. 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 MoreAny Rose Midge Advice?
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."
