| OK so I think I got a problem...a good 70 or so tomato plants have alot of aphids on them. I had a few last year (when I only had about a dozen plants), and after 1 or 2 spray applications of something (I forget what it was) they were gone. This year, they have hit hard, and I am now worried. I hear excess nitrogen can be a cause, but I havent even fertilized yet. (just added one 6-12-6 spike to each plant today). On monday, I tried neem oil, mixed it per the specs, sprayed the undersides of the plants, but it didnt really seem to do much. Does neem oil actually work? Today I shook the plants and then crushed what fell - but im guessing I got half at most - the rest just scurried away. Is this really a viable way to control them? What are peoples thoughts on insectisidal soap? Anyone have a recipe they like? And finally, are aphids just a springtime thing, or is this a season long concern? Last year they seemed to disappear pretty quickly, but I dont know if that is usual or not. Sorry about all the questions. Im just kinda worried all the sudden!!!

| Usually when I have had problems it has been early in the spring and does not reoccur later to any serious degree. I don't know if that is typical however. I treat with Pyola, which is pyrethrins and canola oil and that has always done the trick. I have tried homemade solutions of dish soaps and rinsing and I think it did help but not as well. |

| I've used ladybugs as a safe and biologically-kind deterent for aphids in the past. Most decent garden centers sell lady bugs by the bag. You may want to try them if you're having serious aphid infestation. A bag of ladybugs can chomp a serious amount of aphids before they move on and there's never any harm to your plants and the ladybug carnage on the aphids is kinda cool to observe hehe :) |
