I've got a crop of mixed lettuce, raddish, carrots, kale growing in my 'salad bowl crop'a 6'X 6' area. I just noticed the tiny shot holes of (flea beetles) all throughout the different varieties. Never have had flea beetles in this garden so I was a bit surprised. (Could have come in via the bales of not so decomposed compost that I used to improve this pumice soil)
Could be something else as I couldn't find a live beetle in the soil, roots or the leaves (during the day). I'll be out there tonight.
What else could it be other than flea beetles, any ideas? What I pulled up on the internet was kinda lame but I didn't search that hard. The information said they fed during the hot temps of daylight? And yet all I could find were tiny possibly beetles dessicated in the soil.
Does anyone have any ideas so I don't have to use NEEM? Gee, would that even work? How about Bacillus thuringiensis made with beetles in mind? I know they were working on one decades ago but haven't heard anything. There was one for caterpillars the one we know best, one for flies and mosquitos and one for beetles. Three types of BT. Have not yet seen the beetle and fly varieties yet. Wouldn't it be a good thing to be able to have the BT for flies and mosquitos NOW? Let me know if you've heard anything about BT.
These beetles must come out at night...the leaves are completely peppered with some damage to the crowns of these lettuces. Anyhoo, I am in the middle of majoring canning and dehydrating and getting frazzled. I thought I'd ask for help.
I'll send a picture by tomorrow of course...but tiny tiny little holes...shot hole only 1/4 the size and smaller. Seem to love the arugula and a red leaf lettuce best. Thanks...stormy
