[IBC] black aphid infestation on Ulmus P
Whilst doing my morning perambulation through the greenhouse I note a sudden
attack of what appear to be black aphids on a large-ish Ulmus p. corticosa. Does anyone know of negative reactions of Ulmus when Sevin is applied? I also have Orthene and Malathion immediately on hand... David J.

It oughta be warm enough for elms now in VA. As soon as you're outside the bug problems should abate. But to answer your question, Sevin AFIK won't hurt an elm. What does the label say?

David:
Why not try my stand by. I have never used it on a tree with adverse results (at least to the tree)! ;-) Carl L. Rosner - near Atlantic City zone 6/7 http://bmee.net/rosner http://www.jamesbaird.com/cgi-bin/Ja...d=00000068 48 http://www.jamesbaird.com/cgi-bin/Ja...d=00000068 48 SOAP solution! I pour a solution of 1 to 2 tablespoon dishwashing detergent, 1 tablespoon of vegetable oil into a plastic gallon and slowly add water to fill the gallon jug. I fill this solution from the gallon bottle into a spray bottle and just before using I add 1 to 2 two caps full (from the rubbing alcohol bottle) of rubbing alcohol and spray immediately. If you do not use the full bottle of spray, I suggest the next time you are going to use the soap/alcohol solution add the same amount of rubbing alcohol again, since the alcohol will evaporate. I store this soap/oil solution in the gallon jug for months on end. It does not seem to go bad. Spray on plants covering all leaf and stem surfaces. You may have to spray from three to four times with intervals of three days. I have eliminated almost any kind of pest that have attacked my trees, including scale. I do not wash off the spray and have seen no adverse reaction to the trees from this mixture. David J.
