Sounds like a crazy question I know, but what I have just witnessed maybe it's not. On 1/8/2019 I walked through my blackberries looking for mites and found them on almost every leaf and active. Here is the observations over the next few days.
1/8/2019 I sprayed a mixture of horticulture oil (Damoil) + Brigade 2EC . The mix was 1.3% Damoil v/v +  6.4 ounces per acre Brigade 2EC. Temperature mid 60's cloudy skies
1/9/2019 Walked through and found less mites, they were still active. Maybe a 50% knockdown. Temperature upper 50's cloudy skies
1/10/2019  Walk through found only a few mites none active, maybe greater than a 90% knockdown. Temperature mid 50's clear skies
1/11/2019 Walk through did not find any living mites, nymphs and eggs appeared dehydrated and would crush to power
So now I ask, can a mite live long enough to reproduce after it has been chemically treated?
Cheers
