Imidacloprid

Dear Uli:

You've given me the "guts" to chime in...

My experience with Imidacloprid under the granular form called Marathon
was very positive, but I must emphasize you should use as directed, and
I strongly recommend using another form or two of protection in a cycle,
even if those forms do not control your scale, whitefly, etc. as well. I
knew a graduate student who, at the first sign of whitefly activity
would treat again with Marathon, time after time. The product, of course
lasted a long time each cycle, but she continued to use it in a
greenhouse environment without any thought of some form of integrated
pest management. Within a year, the whiteflies had developed resistence.
