I tried Azamax and struggled, SNS 203 and struggled, I finally hit only my young plants (at least 5 weeks from flower and before a transplant to final pot) with Merit 75 took care of everything, I also keep forbid around after some fucker passed me Broad mites, those damn things are a nightmare to get rid of… almost decided to start fresh when those things hit me (and I had no idea what was doing so until damage was pretty substantial). With Forbid again it's my young plants in beer cups or 1gal pots that get it, if I have to hit my ready to flower plants, their not ready to flower anymore. I caution anyone in using these unless they know what their doing and have the proper mask / hazmat suit to be safe.
Of the heavy duty products out there for foliage, Forbid and Eagle 20 have proven to be has the shortest residual time in plants which is why I use the Forbid over other products. when I have to.
Azamax is my preventative spray / soil drench in veg, shits killer but unless you want to fight broad mites or flying RA for a month, I wouldn't use it for those issues.
