About the abamectin, think im going to consider it has a last choice. Apparently it's not that harmful though, i found this
and it says it wil degradate quickly as far as it is just a thin layer. Don't worry Mikell, if i use it i'm going to follow all the indications and cover the entire plant and pot with it, and probably use some soap as backup
i can get potassium soap, do u think it will be helpful?
Thank you all again
The halflife from that link is for surface residue. Google "abamectin plant residue" and look for references to non surface degradation. It's quite a bit longer.
One user submitted results of testing after 180 days on another forum that still showed residual. Albeit less than 5ppm, but it shows you how half lives only give part of the picture.
Myclobutanil is a good example, with degradation commonly refered to as a "hockey stick" when graphed, re: a quick initial half life followed by slow breakdown of the remainder.
Food for thought. Your choices are your own, I prefer not to judge but simply provide accurate information.
Post the brand or more detailed explanation of the soap, but it sounds similar.
