Aloha everyone, will try to put up some pics this evening. I have a problem with a fairly invasive african grass, kikuyu or Pennisetum clandestinum (which is the fodder and lawn for most of the upper elevations areas of Hawaii). It was growing into my stucco walls. Applied some glyphosate on a non windy day taking precautions (low pressure, large dropplets, etc) to prevent drift from getting to my plants in my adjacent minibog. Looks like some drift did happen. So far the D.capensis "Red" looks like it got hammered. I doubt that there will be any damage on the albinos (planted after the spraying). Seeing a lot of leaf forking and other deformities. Two questions come to mind: 1. being that D. capensis is one of the tougher species of sundews are they just sensitive to small quantities of glyphosate ? and 2. Anyone think they will grow out of it? petiole and leaf deformations. Almost looked like the petioles were developing spines. Oddly looks like these plants are developing new leaves. Will see how normally they develop. May be long term effects of sub lethal glyphosate. Does not look like it affects flowering. Mahalo, Mach Fukada

I'm glad you brought this up. My front yard bog garden is about 20 feet from a busy through road in our city. Every spring, the city maintenance crew comes along with these huge backpack sprayers and sprays the cracks in the sidewalk and the bottom of telephone poles and road signs. I have made a request for them not to spray at my address, but they do so anyway.
It doesn't matter whether the wind is blowing or not, I get deformities in the early pitchers and some early flower stems on my pitcher plants, but it is not a long-lasting curse. I think your plants will grow out of it. Right now, I have a couple of flower stems that have cork-screwed around four or five times!
I think the air disturbed by the constant vehicular traffic in front of my house is enough to cause the herbacide to drift. It only affects some of the earliest pitchers and flowers. Color me cynical or paranoid, but I believe that if I push it, the street crew would end up aiming the sprayers directly on my bog garden. So, I live with a few damaged pitchers and flowers each year.
