Excel LG, Serenade and Actinovate are the methods I would recommend.
Using Eagle 20 is frowned upon. I don't think it hangs around as long as Avid or Floramite does, that stuff can hang around for a long long time, over 180 days but the myclobutanil can hang around for a while.
Here is something someone who had testing done posted, showed that after 180 days there was no sign of Eagle 20.

I have been wondering how long these pesticides stay in the plant and do they really show up when you get something lab tested...
Well 180 ish days ago I sprayed 7 Cuts with the Recommended dose of:
Forbid 4F
Avid
Floramite
Eagle 20
(No I didn't have mites or PM)
Not at the same time, but over the course of 2 weeks...
They Vegged for another 9-10 weeks, then on in the flower room they went..
Well last week after a few week cure it was time to get the samples tested...
I got them tested by Ca Testing Authority...
All 7 samples tested the same...
Avid 8ppm
Floramite 5ppm
Forbid and Eagle 20 free!
I was told by them that an acceptable amount is 1ppm for human consumption.
Now 180 days is a long time and I am not sure how long it actually stays. I don't recommend Eagle 20 unless as a last resort to save some rare genetics for later use.
