How bad are Japanese beetles
Comments (7)Here are some ideas. 1) See if you can convince the homeowners alliance to put milky spore on the whole development. Anyone else there must be having a similar problem. If you can't convince them then at least do your own yard and any immediate neighbors that agree to your doing it (at your cost). 2) Buy a bag of Surround and spray that along with the sevin; cover all the leaves top and bottom. After a couple sprays you will have a thick coverage and that will make your neighbors leaves a lot more appealing than yours. I have run into many horrible problems in growing my orchard, and I have ended up winning nearly all of the battles (salt from the road poisoning my soil, rabbits knawing down hundreds of benchgrafts, swarms of cuke beetles giving melons the wilt, curculio, moths, aphids, psylla, shothole, fireblight, downy mildew, etc). In several cases I thought I was done for but I just kept plugging and found a winning plan. Don't give up yet! Scott...See MoreJapanese beetles are all over on my fruit trees
Comments (30)Ace: Look's like you've got me here. The first FAQ indeed mentions control of the June beetle. This is one of those rare cases where product claims have actually understated their real ability to control pests. Oddly, the last FAQ on the list seems to directly contradict the first. This is the first time I have seen a claim that milky spore controls anything other than Japanese beetles. But the news may be better than that, based on experience here in the past growing season after application of milky spore (as I recall) in late June, 2006. The only previous milky spore application I made was around 1979, and the effect indeed lasted nearly 20 years, although it seemed to weaken in the last few years of that period, and I did have infestations of other types of beetles, as well as some increase in JB's. It turns out that the brown beetles I have always called June bugs are really one or another type of Chafer Beetle, which comes in the Masked Chafer, Rose Chafer, European Chafer varieties, and several other related species. The true June Beetle looks more like a Japanese Beetle on steroids, larger and flatter than the JB, but with a similar iridescent green color of the head and wings. This beetle has never been present in serious numbers here, but the Chafers have often defoliated particulars targets of their choice, especially plum trees and sweet cherries, and done quite a bit of damage to other fruit trees and garden crops too. Chafers feed mostly at night, and their season is usually shorter than the JB, but they are no more welcome. This past season, I not only saw no Japanese beetles, but almost no Chafers either, leading me to wonder if the milky spore had some effect on their larvae too. One swallow does not make a spring, and one season is not really a scientific test, but it is extremely unusual for me to go through a summer season with almost no beetles of any kind. One other thing I noticed in the FAQ's is some confirmation of my belief that the JB does not fly far before beginning to feed, and that the effects of the milky spore will continue to enlarge in area so long as there are larvae to infect. This is consistent with my experience, since I have no JB's, but properties only a few hundred feet away still do. It certainly seems worthwhile to put this milky spore down, although I would go with the pure culture that comes in a can, not the bagged stuff for spreader application which has a very low component of active spore.

Comments (12)I used a professional formulation of imidicloprid when it was first released. It certainly is an effective insecticide. It was claimed then that it didn't translocate to the flowers. After I used it, not only were the target insects gone, but I found non-target victims who could have only been exposed to it through harmless feeding and pollen gathering. No other products were used, and I have no other explanation for their demise. The label on this product also stated it could only be used one time in a growing season. Since it does not seem to be phytotoxic, I presume that means it is very persistant. I have read that it is the most widely used pesticide in the world today and I have also seen the literature suggesting its use possibly linked to confusion and hive collapse in honeybees. I really hated to see it go OTC. It mimics the action of nicitinimides and what are we going to use when every pest on earth becomes resistant? As for only using it on wind pollinated trees, I noticed last year in my stand of corn (and we all know that corn is wind pollinated) throngs of bees and other pollinators. Just because something is pollinated by wind does not mean insects don't visit it. As for sevin, it's very lethal to bees, but at least it has a very short term life on plants. I don't use it either. I don't treat for JBs....See MoreTrees resistant to Japanese Beetles
Comments (1)Neither Dogwood or Magnolia attract Japanese Beetles. The only types of trees that I know of that do are Birches, Lindens, and Willows....See Morecorkball (z9 FL)
