Regarding the article "nonanoic acid" (pelargonic acid: It is also used as an organic herbicide (brand name: Scythe) which degrades rapidly and poses no known contamination threat. It acts by disintegrating the cuticle (shiny layer) of leaves. Since it acts only on leaves and tender shoots, it will not kill plants that propagate by runners: poison ivy, English ivy, black locust, wild grape. A systemic herbicide is needed in cases of such plants. A mixture of pelargonic acid and glyphosphate (Round Up, et al.)has been recommended. The first removes cuticle and the latter penetrates to roots. Neither alone erdicates English ivy. Glyphosphate also degrades within 48 hours.
Thanks for your consideration.
