Hit with spider mites from Chamblee Rose last year - some thoughts

6 years ago

At least one of my plants that came to me infected with spider mites last year came down with Rose Rosette (in the fall).

The fall where I live was weird and was very wet and remained warm for a long time so I had some trouble seeing what new growth was suspicious and what is infected.

I'll look closely in the spring, just an FYI for anyone else who got infected plants.

I don't think spider mites have much to do with it. I planted a bag rose that had RRD about 5 years ago. All my other plants were chamblees. I pulled the bag rose quick. The roses from chamblees are still growing there healthy.

Edit. I'm not saying it's impossible you got an infected plant, I just don't think spider mites are related to RRD.

There's also a bit of unintended irony in qwert's report. If you go back to the first published Phytopathology report of Witches broom of roses/ Rose rosette by Staplin, Allington and Viehmeyer, they were dealing with Rose Rosette and they were trying to keep the vector mites on sick roses in isolation chambers. As well they tried to keep vector mites that hadn't fed on infected roses alive and isolated. Their problem? Every time they thought they had a colony of vector Eriophyid mites established, spider mites would move in and obliterate the vector mites. The spider mites were, for them, THE predator that removed eriophyids.

For quert's rose to have come down with RRD, there are tens of thousands of infected wild roses upwind of that rose. There's no way of telling where it came from, but because of the spider mites' tendency to eat the vector mites, it's just a shame that spider mites are omnivores rather than natures best acaricide.

Kim Rupert wrote about marigold is a spider-mite magnet and as if these flowers spontanenously generate spider mites! My Eglantyne was right next to a marigold! I could not get rid of spider mite until I moved the rose to a different location and alcohol its infected part. According to Field Roebuck, garlic chives deter both spider-mites and aphids. Garlic chives is very invasive and time-consuming to kill. Cutting the flowers off is a must, before they seed everywhwere! If not, you'll spend eternity digging zillions of tiny bulbs. Hi JeriJen: it's amazing that miticide can melt a plastic spoon. I was spraying a hornet nest, and the chemical got on my t-shirt, went through the fabric and burnt my skin. The hornet and wasp spray is cheap, like $2, but extremely poisonous. One guy didn't wash his hands after spraying, ate a sandwich, had a seizure and went into a coma. He had a near-death-experience, and was hospitalized for 6 months. He had to learn how to walk all over again. They should ban insecticides altogether. I told my hubby how the wasp spray burnt my skin, he went out there and dismantled the nest with a stick. It did the job, no need for spray.

Spidermites: I had two bushes infested earlier - short floribundas in a prime (hot, dry) location. All the dwarf alberta spruce had spider mites also. I sprayed once with TetraSan 5 from Rosemania. I sprayed the whole garden in part because I had lost one rose to Rose Rosette. One spraying did it - all species of plant life made a quick recovery. I know the roses had red spider mites, the spruce another type. The TetraSan handled both. I have since added some of those water crystals to the soil under the two floribundas that were infested to help maintain some humidity. Short roses in hot locations seem particularly prone to spider mite infestations. I taught DH to spray down the spruce thoroughly every time he waters or has the hose out for something. I don't know what it is with those dwarf spruce though - they all have nice locations, nice soil, heavy mulch. I think they are just annoying me cause DH likes them and I don't.

Steve, I think that's what they call a Velvet Ant, it's a wingless wasp. Spider Mites don't have stingers, and even if they did they're way too small to penetrate human skin. They have mouth parts similar to regular spiders but use them to rasp the surface of the plant and then they suck up the juices. The tiny stipple spots are where they've scratched and sucked up the plant juice. A close up of the Two Spotted Spider Mite. This is a common one, but they're many kinds. And how they look to the naked eye, up close. You can see the fine webbing with mites crawling on it. They're the tiny dots. It does look fairly different than regular spider webs. And here you can see the stipple spotted damage on a leaf; This is a pretty bad case on a lemon tree. The webbing, the tiny mites and the stippling can all be seen here. If you click on the pics, most will show it as a larger picture.

Susanne - Do the leaves look like this? The brown speck is dirt. I noticed that a few of the leaves have a light white dusting. Not sure if it's just dust or something else. I also noticed this morning that there were spider webs. The last several months I've had problems with house spiders so initially I thought it was just my usual spider problem, but now I am wondering if it's a case of spider mites. Here are photos of the webs on the key lime. I've been having problems with the key lime plants. The lemons are fine, but I'm not sure if it's because they are are so much larger than the key limes.
