windswept Erythrina caffra

[fastfeat]

A nice, large prostrate tree on a bluff above the water in Malibu. These trees really thrive with constant ocean winds.

Nice specimen. That is one the borers devestate here.

Does Dimethoate work well on Florida Erythrina borers? I've got a jug of this stuff that I've used for bamboo spider mites but nothing else (so far...) since it seems like such a "nasty" product, but I'm trying to grow some Erythrinas and would opt for using this "serious poison" to keep a few of the nice ones alive/healthy, if it would work (?)

My Erythrina "history" so far is:

Erthrina arborescens -- killed very quickly by borers

Erythrina x bidwilli -- doing "well" but currently under attack by stem-tip borers

Erythrina crista-galli -- same as above

Erythrina herbaceae -- no problems so far (Florida native)

Erythrina indica, caffra, speciosa, lysistemon -- ??? (exact ID unknown) -- killed by last winter's cold spell -- although, from what Eric said, that was a "mercy killing" re: the probability of death via borers

Erythrina livingstonia -- died (it never did well -- don't really know what the issue was)

Erythrina madagascariensis -- still looking dead from last winter's cold spell (and it was hit hard by the previous winter so it never got a chance to get some size/strength -- don't know if borers were also an issue or not)

I did just treat my two remaining (borer-impacted) types with the Bayer 3-in-1 product and will wait to see if that does the trick before trying anything else, but I would like to know if Dimethoate is a good next step or not, if needed.

Thanks,

Tim

Hey, you're in town!

Wanna visit a couple of premier California palm gardens?

I just sent you a PM with my phone, give me a ring if you want. I'll be around all day Saturday & Sunday, and I can take you to see the Hoopers' place, too, right down the road a spell of a short piece . . . . .

I am always amazed at the diversity of California trees. It is good to see a little imagination used because it seems like people use the same things over and over again here.

Tim--

I can't say I'm familiar with dimethoate's ability to control borers. Are they listed on the label?
