ISD Treatment for Florida Citrus
Comments (1)From some recent reading, I think that means its been treated with the insecticide Imidacloprid (or possibly a few other similar). Also see: http://forums.gardenweb.com/forums/load/citrus/msg020857176605.html...See MoreCitrus problems migrating to non-cirtus plants??? help!
Comments (1)JM, Those are False Oleander Scales. The dead scales won't be loosed unless you scrape them off with your nail. Another poster some time back wrote that the yellow mouthwash full strength will kill the scale. I had them on my Siberian Iris and Oleanders last year and this year they found my Star Magnolia. I used a cotton ball soaked in the mouthwash and wiped the leaves clean and then sprayed the plant with the mouthwash. I'll have to wait and see what happens next. Last year it was so bad that I had to cut my oleanders down to the ground. In the future, as soon as I see one, it will get the whole treatment!! I'm through fooling around and thinking things will just go away. There is a link for you on the herb forum....See MoreIs this a good area to plant Citrus trees?
Comments (8)Hermitian, we trap all the time. Last year we got around 35 or so. I have not tried poison, but I would be concerned about them possibly coming above ground to die, as we live in a suburban neighborhood with cats and we are near a wildlife preserve and get a lot of coyote, skunk, raccoon and hawks. What kind of poison do you use? One neighbor used to have about a dozen feral cats and the other had a thick brush/hedgerow area decades old with a resident owl, and we had very little gopher troubles then. Cat neighbor sold the house and the cats went to the pound, and the other neighbor cut down the brush are and the owl left. That was about 7 years ago and we had a huge population boom of gophers. First year we trapped almost 100. It has gone down a bit but like Patty said, there are always more moving in from the surrounding area, one gone, one moves in. Patty thanks for the idea of hardware cloth cages. That will give me a few more years I think. I think it's better to plant in spring, so I could make the cages this winter. There is an old irrigation system from the previous owner, but it was done with very cheap plastic lines and the gophers,(again!) chewed holes in them. I will do drip but leave the main lines above ground, probably mulched, so I can see and fix any chewed areas easily. It used to be a home orchard with stone fruits, you can still see a couple left. But this area was not fenced back then and the darn deer really destroyed his trees over the years. The couple left have big strips of bark missing and are on their last legs. Now the fence keeps the deer out mostly, plus I don't think they are as fond of citrus leaves as stone fruits leaves, though they will eat them if there's nothing else. I think Steve was mostly saying that his plants do better in the ground, even the semi-container ones without bottoms. Not that it would deter gophers....See MoreCitrus Pests - What do I try next to get rid of them?
Comments (15)Hey heavensabvus1, you keep getting rid of these critters but if you enhance the natural immunity on your plants, you may be able to deter these bugs for the long term. I recommend working some worm castings into your soil or better yet, innoculate your soil with worms. Worm castings contain an enzyme called chitinase which eats away the shells of many insects. It will take a while for your plants to absorb these enzymes but it will save you a lot of trouble down the road. You may also want to innoculate your soil with beneficial bacteria and fungi. You can buy prepackaged organic fertilizers like Kelloggs at Home Depot that already have these organisms. These organisms form a symbiotic relation with your plant and soil rhizosphere and protect the plant and inhibit insect attacks by several mechanisms. One of these mechanisms is the direct infection of insects by some of the fungal or microbial organisms. Some of these microbial organisms, the bacillus species for example, are naturally found in the soil and certain bacteria and fungi can directly infect and eventually kill harmful insects. To get rid of your pests, I would also highly recommend putting out ant bait stations. Ants innoculate plants with aphids in order to create a steady supply of sweet plant sap. The ants pretty much farm the aphids. By getting rid of ants around your property, you should see a dramatic decrease in your aphid population. To directly kill the aphids, I recommend using Chrysanthemum tea. Chrysanthemum contains a chemical called Pyrethrin which act as a mild natural insecticide. You will have to spray your trees every couple of days for about a week or two untill the insects finally realize its futile. The aphids will eventually come back and you will have to spray again but hopefully your tree has absorbed enough chitinase from the worm castings and also your beneficial bacteria and mycohrizzal fungi would have established itself well enough in your potting soil that even if the bugs did come back, they will take one bite out of your plant, vomit a little, and scuddle to your neighbors yard for some greener pastures :) Beware of those ant bait traps around pets, small children and rain however. If it rains heavily in your area, the poison can get washed into your soil. I try to stay organic but I haven't found a good way of getting rid of ant aside from the bait stations. Good luck with your citrus!...See Moremalcolm_manners
