Also Richard, you seem to have glossed over a very important part of the Forbid 4f label.
“WHERE TO APPLY: To shrubs, trees (including non-bearing fruit and nut trees), flowers and foliage plants in outdoor landscapes.”
I’ve mentioned that several times before, have you read up on the topic?
Treating new plants and cuttings prophylactically while quarantined away from the others is the best practice to avoid fig bud mites in the first place. If all sellers did that (with a known effective miticide), there wouldn’t be a problem in the first place. But because of the controversy and misinformation, they have plenty of excuses to choose from, and not much risk to their businesses since people who get stuck with the problem are more likely to just leave forums rather than contradict a unified front of sellers. It is a real shame, so much valuable experience lost from legitimate growers.
