|Okay I'm going to give it a try.|
As you know I have Rose Chafers and Jap Beetles in biblical purportions,
plus Rose Slugs and host of other rose destorying insects.
It doesn't kill earthworms and it doesn't make the pollen toxic.
(I called them on this).
It doesn't even smell bad.
Have you used it and how well did it work for you?
Still waitn gfor the milky Spore to kick in.
This will be 2nd year after application.

|It looks like I have blackspot on my yellow minature rose bush so I purchased Bayer advanced..rose and flower care product. On the front label it reads 3 systemic products in one..My husband made one batch up(1 qt.)yesterday and poured it around the base of the rose bush. We had almost an inch of rain since last night about 5:30 pm. This morning about 6 am, it was really raining hard, now it has stopped, but supposed to rain more. We really do need the rain though so I'm not complaining.|
What commercial product for blackspot and mildew have you found successful for you? Or a home remedy? Example:baking soda, water, dish soap or light vegetable oil
Can I apply the baking soda solution on the foliage after the rain stops or should I wait for another day when it's sunny and the foliage is dry to apply? Another remedy mentioned somewhere was a cornmeal mixture.
Curious to know what you have found to be the most effective for you? How often do you apply it?

Bayer makes a product called 2-In-1 Systemic Rose & Flower Care, and also makes a product called 3-In-1 Insect, Disease & Mite Control. Which one are you using?

|Pippi...I don't spray for fungal diseases.|
I've tried various products (organic and chemical)
and they probably work if you use them before the condition appears
and use us it consistently.
I have eliminated roses that are prone to BS
Some of my will get some BS around August
on their lower branches but by then
I'm not too worried about what they look like.
Mike I'm using the Bayer "All in One"
It's a fertilizer, anti-fungal and pesticide.
I applied it to several smaller roses
and it seems to be working fairly well but not 100% effective
and its definitely not repelling the Rose Chafers but supposedly
they are suppose to die if they eat from a treated plant.
With the numbers of RC i have, it would be impossible to tell.
I bought 2 Hybrid Tea Roses this spring on an impulse and I'm going to
treat them every 4 weeks and see what happens.

|Ideas for controlling Rose Chafers|
Ideas for control in above and other sources include: hand picking, early spring cultivation beneath roses, repelling using mothballs or onion/garlic, trapping - as with Japanese beetles, nematodes - as with JB's.

I've tried all organic approuches to controling RC
except Nematodes which i need to put down
for sure this year.
I'm going to order some traps today.
I heard traps actually attract more to your property
but with as many as I have to try some anyway.

|When I had a half acre lot in NJ, with six traps I was able to trap six quarts of Japanese beetles in half a day on peak days. Not fun disposing of them... I think if I had a larger property I would trap at the same rate of 12 traps per acre but I'd probably put most of the traps near the perimeter of the property so that any JBs that came onto the property stopped near the edge. My belief was (based on only a few very uncontrolled experiments) that JB's decomposed slowly, but made for great fertilizer. |
(I still have fond memories of walking through the garden beating all my roses, vines, and shrubs with a stick to scare the beetles off the plants in hopes they would go into the traps. Ahh .. those were the days.)
Since they look so much alike, and their life cycles are so similar, I'm guessing that some of the same ideas will work for rose chafers.
On second thought, it might make sense to place the traps near areas where roses are being grown, but not directly in the same beds.

|I just got some of the more expensive re-usable Jap Beetle traps with a sex and rose scent lures that are suppose to last for the whole.|
We'll see how it goes but the business I bought them from told me the only way to stop them totally is placing a trap every 50 square feet. He wasn't trying to sell me more, rather was being honest that the traps really aren't going to control them that much. This info was based on test trials done at Michigan State U in a peach orchard.

|I have been using the Bayer 3 in 1 this year. It seems to be helping reduce the beetles. I still have some, but less than last year. If I turn the bug zappers on at night, it gets a lot of beetles - both the Japanese beetles and their beige relatives. I read that the traps should be put downwind of your garden. I didn't put any up this year because I don't have a good place to put them. I am afraid that they will draw more beetles to the garden. A neighbor hung one, so it may help. I also dunk a bunch in water daily, they prefer one rose at the moment -Austin's Wildeve. The neighbor kids like to help.|
