I've been getting a flare up of mealies on a few of my paphs and I was using Malthion which seems to not be doing any good anymore. Maybe they've become resistant, maybe I should apply more often, I'm not sure. The question that I have is, I went out to buy Bayer Rose and Flower insect spray and couldn't find it, but I did find Ortho Rosepride Insect Killer with acetamiprid. Has anyone used this product? I'm nervous about using something new and not sure about the effectivness. Weigh-in please.

NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
you said it, they have become resistant. it is imperative to rotate rotate rotate modes of action of pesticides.

the chart referenced here is helpful: http://www.slippertalk.com/forum/showthread.php?t=10098&highlight=mode+action

they suggest three different modes of action

i have used TriStar, which is the professional formulation of acetamiprid for several years. i like it. i have not noticed phytotoxicity (damage to the plant because of the pesticide) on anything. i believe it is even safe to use on poinsettias in bract.

sorry about the rant but pesticides are dangerous!

if you feel like reading, i tried to make sense here:

Wow, thanks for the link. A treasure trove of insect killing info. I will try the Ortho and I will rotate. I'll let you know how it goes. THanks again.:wink:
 
I keep Orthene, Merit, and now SucraShield in my arsenal, have them labeled "1", "2", and "3", and put the last one used in a plastic, zip-lock bag.

When treating, I use the next number (above the bagged one) in the repeating sequence for three consecutive weekly treatments, then put it in the bag. That way, I don't have to think about which was last.

I also tend to mix Enstar II (an IGR) with the insecticides.
