Never use the same active ingredient more then 3 times in a row. If you have a serious infection use different products from different classes of active ingredients.

Do you know what the active ingredient is?

Izzie, did you track something down yet?

The active ingredient in most of the Bayer products is imicloprid. It is a systemic that works very well and is especially easy to use outdoors or in a shade or green house. They have a formulation the comes in a sprayer bottle ready to hook to a hose. Works great. It takes a little time for the plant to absorb the poison into all it's leaves so you still need to cut back heavy mealy or scale infestations or clean them up with alcohol or even orthene spray first. Then use the Bayer spray every 3 months or so to prevent the infestations. Working good for me down here in buggy south Florida.

Not a systemic that works for the mites, but after alternating with bayer systemic, immunox, and Bayer's End All (neem and fatty acid salts), it's starting to die down. The poor roses definitely look worse for wear. :(

Thanks for checking back. :)


For orchids that might have mealies- I've been wondering if soaking the pots in a neem oil solution would work? I can get a 70% solution that I could dilute in water....

I've been wondering. I have the Bayer 3 in 1 for roses. Due to it having fertilizer in it, I have to use it in a VERY low concentration to keep the ppm down around 150. Does that low of an imidacloprid concentration even do anything?
