Brought in a few clones from other growers, got the mites =(
Started with the organics immediately; needed/wanted a systemic organic! Googled away found a little nugget =)
"Systemic use of spinosad to control the two-spotted spider mite (Acari: Tetranychidae) on tomatoes grown in rockwool"
Google it peoples!
1. It's a study on how soil drenching (spraying on leaves was less effective) with Spinosad growing in Rockwool kills mites; and the study says 100%.
2. Stays in plant tissue killing mites for 30 days after drench.
3. New cutting or clones started into untreated Rockwool, Spinosad stayed in plant tissue 14 days.
4. More than one medium tested, Rockwool cubes 6.5 · 6.5 · 7.5 cm, 100% Sand, 70% Peat-30% Sand, 95% Sand-5% Clay, 100% Sand, 100% Black Earth.
5. Soil Drench 100% kill rate in Rockwool, (60% kill rate) in Sand, (42% kill rate) in 95% Sand- 5% Clay, not much killing in other mediums tested.
6. I had to make a special request for the complete study, not sure what I can post here? Request the study some other smarter members; please add to what I've missed or misunderstood.
7. If you wouldn't mind posting or calculating how much of a few Spinosad containing products we'd need to use in a drench, according to the study?
