Whitefly egg problem

Post  Barry M on Sat Jun 15, 2013 10:47 pm

Hi - I did a search in IBC's Pests and Diseases and couldn't find anything about whitefly egg control.  Anyway, I'd like to leave my pomegranate plant outside as late in the season as possible but in late August or late September the tree gets attacked by lots of whiteflies.  Getting rid of the whiteflies is not easy but getting rid of the tiny, transparent eggs is even tougher (much tougher).  I don't want to use any pesticide and I'd like to know if there is another remedy that would kill the whiteflies and especially the eggs.  Is there something I could put on the leaves to do the trick?

A soap spray will take care of whiteflies and it is NON-poisonous.  You may have to apply weekly in the "season."

Moving to pests.

Jim,
Do you have a favorite recipe for whiteflies? I have them on some Japanese maples, bald cypress, and elms. Thanks

Mine is right out of Rodale's Encyclopedia of Organic Gardening:

"1-3 teaspoons of household soap (NOT detergent) per gallon of water . . . "

Some folks add a tsp of rubbing alcohol, but I don't.

Jim,
Thanks. Have you ever used neem oil?

No. And I would not in the summer. It is oil based. I also have some doubts as to its safety. Just me, maybe, but Me is who I live with.

I don't spot much that "goes against a couple of things" I said here. I did note this was from the prime organic gardening spokespeople, Rodale and was a quote from the book. Rodale isn't partial to detergents, and neither am I. Ivory Soap is a much simpler chemical compound than a detergent. The detergent vs soap thing is covered here: http://www.ext.colostate.edu/pubs/insect/05547.html

Maybe it's not an issue in Milwaukee, but down here in our summer heat I'd never, ever spray a bonsai with anything with an oil in it. Deep fried bonsai is not on my menu. Oils are OK in winter.

The important thing about soaps/detergents as insecticides is that they work as a "contact spray," meaning that an insect has to be drenched in the stuff to be killed. Simply spraying the entire plant with the soap spray will do nothing if there are no insects present. It has no residual activity of ANY kind.

hey jim,

the couple things were just that... the soap vs detergent and the oil...

oh, yeah and the alcohol   drunken 

but like you said, some factors are dependant upon where you live...

i think the contact killing thing is that it suffocates them because they breathe through their exoskeletons... and the repeated spraying over the course of a couple weeks kills as new ones come up though various life cycles...

or something like that... scratch
