Imid has a long half life so u know. But when I used the .72% I used 30ml per gallon with success. I also watered with spectracide triazicide at 45ml per gallon for contact kill, at the same time as the bayer. U can mix them both in the same container without any probs to the plants.
So if I were using ur .25% id use 80 to 90ml per gallon. But be careful with the dosage if ur bayer comes with food in it.
thanks for the heads up MM,
I've seen the info posted in this thread a million times
and when I need it it disappears lol
