Please answer my rose slug question. Tx
Comments (14)>Other question: Do rose slugs only feed from the underside of the leaf??? Has anyone every spotted them on the top side of leaves or on the canes??? Jim, my memory is incomplete. I might have seen some on the tops of leaves, but if so, that's not the most common place to find them. For sure I've seen a zillion of them on the canes, as well as the undersides of leaves. I've also seen multiple times when canes were chewed all the way around, sometimes leaving just a thin thread holding the upper part of the cane still attached but hanging down totally upside down. And I've often seen long, often not so shallow, chewing cuts into the cane, going down or up the cane from somewhere in midcane. Usually, but not always, this results in the cane turning totally black throughout that cane area, necessitating that that dead cane be cut off and sealed. And if I didn't seal the ends of any sizable cut cane, that cane would become black fairly quickly and have to be cut again and sealed. Lots and lots of that happening here, starting in April and going on well into the fall. Until the start of Rose Rosette Disease here, this was by far the #1 problem for our roses--with blackspot, cercospora or anything else not even coming close. My theory is that because our yard has lots of woods and also some pretty low damp areas (especially last year when we had an unusual amount of steady rain throughout the summer instead of drought) it has or had conditions especially liked by sawflies. >I even found an article with the exact picture... I don't think I remember ours being curled around, though some might have done that and I was just focused on the straight kind. Using photographs, I've seen many, many straight ones climbing canes and on stems. They are hard to notice with the naked eye, but enlarging pictures on the computer screen works wonders. I don't have pictures of the undersides of leaves, but for those I turned over, I could notice them with the naked eye better... and there were a lot of those there too. == >I've used iron phosphate products for slugs and snails and it works, but I don't think it's effective for the sawfly larvae. Thanks for your information, Hoovb. Oh, well! We already do have the product, so we'll give it a try anyway, hoping that our varieties are a bit different than yours. Grasping at straws here, I know... The roses I started trying the product out with a couple of weeks ago have already succumbed to RRD, though, so I've no idea thus far on whether there's any chance that it might work here. Your post inspired me to actually read the label (novel idea!) and I did not see any of the specific types of slugs mentioned there that I could find in one of my books as some of the sawfly slug varieties that can affect roses, so your experience might well predict ours too. On the optimistic side, though, it does say that those particular varieties listed aren't the only kinds of slugs it will work with, and mentions also that it's effective for slugs on blueberries and apple trees (plants with some relationship to roses, I think). Anyway, we'll see... assuming that by the time RRD is finished with us here we have some roses left to try the product on. Oh, I did read one other interesting thing: if you don't want to pick each and every one off by hand--no chance!--one of my books says that a strong spray with the hose will work. I don't know what percentage will have the strength to climb back up, but the spray coming from the side will at least put them at some distance away from the cane (and for all our new roses in the pots, they'd have to climb the pots too). I've been mainly doing that for aphids, but it will certainly be a bonus if it helps with rose sawflies too! Best wishes, Mary...See Morecompost questions: snails/slugs + compost tea
Comments (3)If your composter is dripping a liquid the material in it is too wet to properly anerobic compost. There should never be any liquid runoff from a properly constructed compost pile, even one in one of those really expensive and unnecessary commercial things. Slugs and snails are part of Ma Natures recycling machine but they do not distinguish between living plants and dead plant materials and so are considered pests. About all they will do in your composter, besides digesting some of that material, is mate and lay eggs to spread around your garden because as wet as your compost is it is a very good envinment for them....See MoreSlug Hunting This Morning -- Gray vs Brown Slugs
Comments (14)Coll, you say" So I either spray and melt them on the spot or cut them in half with a tool if I have one handy. I read that if they have even one eye left, they will live. You can squash them with your foot, but cutting them in half is just making two of them, or so I assume. This is really a gross subject, reminds me of a slobbering bulldog with strings of slime getting on my hands, and I really don't like that....although bulldogs are fine, nothing against them, just their drool!!! You all have some exotic slimeballs to deal with, mine are all one kind, that wet gray color. My turtle disappeared, have not seen any frogs or toads this year, so it is up to me and the ammonia and Sluggo Plus and any other chemical in my arsenal. I had to stop with the pellets while it was raining so much, but now I must resume the back breaking job of spreading Sluggo on the ground, and ammonia in the pots. It's amazing to me that tender plant roots do not die from the ammonia, because it destroys my skin if I come in contact with it--or bleach for that matter. After I treated some plantaginea with a bleach solution for foliar nematodes, I had dermatitis for two weeks....it got on my hands and kneecaps, don't know how that happened....See MoreSlug size question?
Comments (2)We have various kinds ofd slugs, from small to large. But we aslo have the babies -- they hatch as 1/8-inchers. The same tactics work for all, be that search-and-destroy or baits of whatever kind you're comfortable with....See MoreMearth
