Aphids

[Beng]

My neighbor has lots of roses so I'm pretty sure she has aphids and i know she has whitefly from time to time. My garden is regularly sprayed with Neem oil i also use Bifen and Merit in early spring as well as the insect growth regulator Azamax. I have no bug problems in my yard except on one small pyrus kawakami I got from Brent late this spring. It's an aphid magnet so I keep it away from everything else. I spray it with neem, they all die, a week later they're back! That said I hope to develop it into something and would like to permanently eradicate them! I have plenty of Umes, plums, and other fruit trees which they avoid cause of my systemic treatments but they could care less on this pyrus, they just love the thing. Guess the leaves taste good. I'm sure they're coming from my neighbors yard which I can't spray, how can I treat the pyrus so they won't like it anymore other then getting rid of it.

imidacloprid

Just checked Merit's active...and it is imidacloprid also. :O

I use Bayer Tree & Shrub (pellets) and nothing touches my apples, quince, plum, etc.

Maybe it's because these came to me in mid may and they only got hit by merit once. All my other trees got a fall treatment and 2 spring treatments.

I find if I keep them at bay with a good spritz of hose water that seems to minimize their hold and I'm not worried about a spray that might drift into my koi pond.

Just went out and dosed that little guy with merit. Hopefully they'll leave him alone from now on....

Yup,them critters can really take over.I am keeping a close eye this year on my elms so them teeny white things don't take over like they did last year.I finally resorted to insecticides this year (ortho bug b gone) and it is so much easier than using a squirt bottle of water.Does great with the aphid magnet Japanese quinces.Good luck with your Pyrus.

Unbelievably they're not interested in my quinces at all, which says a lot about Merit and other insecticides using the same active ingredient like Bayer. Hopefully this follow up of Merit gets enough of the poison present in the leaves to make it something no longer tasty.
