The advise is good as far as treating new introductions. Orthene is rough stuff. I'd think about using something else. There are other systemics, but I use coffee.

PM, what does the coffee do? Are you treating new introductions with this?!

The alkaloids in coffee kill insects. I take the used coffee grounds that Starbucks gives away for free and make "sun tea" from that. Coffee sun tea as a direct contact spray will kill aphids, thrips, scales, mealy bugs, and spider mites. One bag makes a 55 gallon drum full of spray that stays viable for 4 to 5 months. I just tap what I need whenever I see insects. I am in Florida and have 40,000 plants to take care of so there is always something popping up. In this case, I dunk the whole plant and pot in a bucket of coffee tea then let it all drain out. It kills all those insects on contact. I published an article on this 10 years ago and can be found online. It is a cycad related article, but it shows my barrel. You can scale down and use 3/4 pound of used grounds in a 5 gallon bucket. Search the word coffee and Tom Broome and the article should come up. All I have used in my nursery for 12 years is my barrel and sometimes, grounds in the pots to kill insects systemically for 5 months. Not on AVs though. It works great on my hot pepper plants.

Thanks for the great info! I’ll look for your article.
