Do you use Sevin on anything in your veggie garden or flowers?
Comments (11)One web page says it is moderately toxic to mammals and it does kill honey bees and other insects. Last year I lost cukes and squash to cucumber beetles. Since I planted different varieties I noticed that some varieties didn't seem to be bothered by striped cucumber beetles. i.e. zucchini romanesquo. Squash bugs followed the cuke beetles. I replanted the winter squash only to lose some beautiful squash to gnawing critters. I am trying not to use any pesticides. So in addition to growing varieties that don't seem to be bother much, this year we kept the zucchini bed under a fabric low tunnel until almost 4th of July (I'm in NH) and the plants were getting huge. I also use this tunnel in the fall to protect a late planting of bush beans. I did find a couple of striped cucumber beetles. They were frequently spending the mornings inside the female blossoms. The squash bugs have started so I have been going out in the morning to scrape eggs into a bowl of soapy water. I also grew some cucumber plants inside and put them out as young plants with some marigolds which are reputed to repel cucumber beetles. I still lost a couple of plants but I'm not sure which varieties. The rest of the little patch is doing fine and we are eating cucumbers. This year's winter squash were planted in a new area on the other side of the house from the veggie garden. I thought maybe the bugs wouldn't find it this year. The seeds were planted late but look like they are doing fine. I did find a couple of beetles but no egg masses .... yet....See MoreJapanese Beetles again
Comments (75)My garbage can still smells bad from last year when I filled it every day with grocery sacks of JBs. I always emptied the traps early in the morning so I could get cleaned up afterwards before going to work. A couple of times I used Clorox spray bleach on my hands to get rid of the smell. Ah. Good times. I do believe the plague is about done here. I see a few here and there, but no swarms. I'll be spreading more milky spore when the weather cools and we get some rain...if the weather cools and we get some rain. It is supposed to be washed into the soil fairly soon after spreading for best effect. There's no way I can water it in everywhere I need to spread it, so I have to wait for rain.

Comments (16)GIO I'm going to look into finding the red dye as well. Are you planning on water, clove oil, and the red dye? I'd much rather use that than the Sevin... Yes, I'll be using the red dye, water, clove oil and other containers with the dye and tayuya root powder, which I have. No Sevin. The only place I could find the dental disclosing tablets was online. Your dentist might have some tucked away in a cabinet somewhere -- I'm not sure how common their use is these days, though I think they're used to help children brush thoroughly! But check to be sure the dye is #28 red, since #40 red is used sometimes. Also, about the clove oil. One woman tried it when we were experimenting but apparently put it full-strength and *some* liquid Sevin in a plastic cup. She reported that the next morning the bottom of the cup had melted away! I read later that undiluted clove oil WILL melt plastic. I used styrofoam cups and probably a greater dilution of the clove oil with water and didn't have any problems at all. Good point about the yellow containers. I got excited about making it more effective without considering the consequences to the pollinators. However, is the red dye toxic to the pollinators? The red dye will be consumed only by the insects attracted to the lure it's mixed with, and that's ONLY cuke beetles, not the pollinators or other insects. The reason is that the chemical compound, cucurbitacin , is in the lure that attracts cucumber beetles. It exists in varying degrees in all cucurbits, but the beetles flock to some cucurbit plants in droves and less to others, quite likely because of the strength of the odor. OTOH, pollinators are attracted to the cucurbit flowers, mostly through the kind of light emitted by various colors and probably the nectar in them, and cucurbitacin is of no interest to them. (Thus my reluctance to use anything yellow as a container in hopes of attracting the cuke beetles -- that might indeed attract the pollinators, too.) I hope your garden won't be as infested with cuke beetles this summer as last year! The kind of cucurbits you planted may have been the lure for so many (I didn't check your list against the list in the link), so if you can avoid growing them again, maybe the beetles will be smaller in numbers and it won't be a losing battle to keep the numbers low enough that you can harvest most of what you plant. That's about all we can ask of nature! I have Crenshaw melons, tomatoes, and beans out in the garden right now and haven't seem any insects so far except for flea beetles. So when these pests show up (and I know they will) that's when I'll set out the baited traps. I'll report back occasionally on how well it's working. It would be great if you (and anybody else who tries it) could do that, too. Report success OR failure. People have a tendency to not think about insect problems until they show up in THEIR garden, so it's possible that some who aren't interested in killing every insect on their plants will look for a solution a bit later in the season. I've never had to deal with Japanese beetles, but a zapper over a koi or other pond sounds like a great way to get rid of them! Sounds like you have some fun projects to think about!...See MoreCan't my Hibiscus get a break? - Japanese Beetles
Comments (6)Bayer Rose and Flower Care. JPs are smarter than they look. They somehow figure out that eating the leaves of the plant will kill them, so they tend to cluster around the flowers. However, this makes it a bit easier to use some of the other controls, such as knocking them in a bucket of soapy water or using the pyrethrin sprays. I typically only use this product on Roses, crape myrtles, and persicaria (the worst JP offenders in my garden). Pyrethrin sprays. These are generally packaged as generic insect killers or wasp/hornet killers in an aerosol can. Look at the list of active ingredients to find one. The only drawback is that tender young foliage may take a hit from these sprays, so be conservative with the spray until you know how the foliage will react. Also do not use on mandevilla vine. I used it this winter to treat mealey bugs on a mandevilla vine that I overwinter inside, and it promptly dropped all its leaves. Didn't kill it, but it came close....See Morewayne_5 zone 6a Central Indiana
