Spider Mites on Junipers

Post  Billy M. Rhodes on Fri Jun 15, 2012 3:22 pm

We had a club workshop on Tuesday evening where member brought a tree to be worked by Visiting Master Rodney Clemons. Three of four Junipers brought in had Spider Mites.
I have looked at the UofF web sites and found a long list of chemicals that are supposed to be effective, but translating that to products on the self for those without a commercial applicators license I only found Bayer Advance 3 in 1 to have imidacloprid one of the recommended chemicals.
I also called our local Ag office and they recommended a home remedy.
One gallon of Water
2 1/2 Tablespoons of vegetable oil (not olive)
2 1/2 Tablespoons of baby shampoo
2 Tablespoons of Baking Soda can be added to fight fungus
Shake well
Spray thoroughly
Keep plant in the shade
Wash with clear water after 24 hours.
Repeat in 5 to 7 days
Continue as needed to control
Fertilizer with a seaweed based product.

Seems like exactly how Neem oil is prepared too (but dishwashing liquid is usually suggested instead of shampoo). Did they mention anything about sun exposure while being treated?

Billy,

I thought imidacloprid usually causes spider mite outbreak? (the reverse) Can you verify your source?

I've only had one outbreak of spider mites, and I cured that with a simple HARD blast of water into the canopy.

I am corrected. The Bayer 3 in 1 does say it will kill Spider Mites, but the U of F site does not recommend it.

My mistake was doing some cut and paste.

Billy, I bet it is another active kills the spider mites not the imidacloprid.

Re: shade while treating with oil based solution...that is very critical, otherwise the leaves may fry and cause more problem than the spider mites themselves.

I've only had spider mites twice. I mix up some nicotine sulfate with water and spray the whole tree. It killed them dead.

i think it is the effects of UV in sunlight that render the active ingredients inactive so they dont actually work - rather than making a deep fried tree branch - between you guys and the Scottish everything gets fried !! Very Happy and smothered in cheese............now i am hungry Laughing

Bifenthrin (a systemic) will do the trick. I think this us still available in US Billy ? Sadly it isn't available to the amateur anymore in the UK.

This should do the trick too (good old Malathion) http://www.scotts.com/smg/catalog/productTemplate.jsp?proId=prod180018&itemId=cat50080
