[QUOTE="danl, post: 1050561, member: 229"] I am still obsessing with the Johnson grass thing. I figured there must be a test for it. I found a article on the internet written by Dr Lacefield and Dr. Smith at the Univ. of KY on testing for prussic acid using cyantesmo paper strips. So I ordered some, it isn't cheap. About $55.00 for a roll in a neat little dispenser. According to them you put the suspected plant material in a zip lock bag. It is better if the material is crushed up and exposed to heat. Like on the hood of your truck- in the sun- in August-on a hot day. I can do all of those!!! Last night I pulled some cherry leaves and stuck them in a zip lock bag, and put them in the cab of the farm truck. They should be well wilted and distressed by the time I get home from work. If anything is going to give off cyanide gas that should do it. I will stick the paper in the bag. Do you think I should inhale deeply?? [/QUOTE]
