Well I have purchased the
Avid. But I have come to the conclusion that, if most of you are like me, I am the reason for the mite spread. I am very intimate with my plants. I touch them daily and that is the problem. We intimate growers inadvertedly spread the mites by touch. The larve and eggs of rust mites are very "clingy" and will attach to almost anything that touches. Then it is transplanted when we touch another plant. This can explain why it might be so hard to eradicate them. The
Forbid 4f is an Ovicide unfortunately it takes about 4-10 days to get complete results. It only takes an egg 2.3 days to hatch and if it hatches before the
Forbid reaches it, it can move to a nonforbinated part of the plant to continue the onslaught.
Forbid is NOT systemic. It does not spread to new growth. However,
Avid is!!! Yet
Avid is NOT an Ovicide and will not kill eggs. The two should be used in conjuction(opinion) along with a third and fourth product. Now it is known that
Forbid has a 45 day life in the plant and
Avid, 30. BUT THAT DEPENDS ON IF MIXED TO MAX OR MIN SPECIFICATIONS READ LABLES.
What Bayer doesnt tell you, because of
Forbid's MOA (mode of action) or its way in, if not mixed strong enough, its chemical comp makes it rather easy for nasty to become super-nasty.
