Case Study: Mycoherbicide

Field bindweed and hedge bindweed are considered among the twelve economically most important weeds. S. convolvuli LA39, an effective BCA of both bindweed species produces elsinochrome A as a major metabolite. Data obtained from greenhouse and field trials showed that elsinochrome A (1) is rarely present in the applied product and if so, in amounts which are far too small to pose any risk to the environment or the consumer; (2) is not produced on the crop or the bindweed. These observations suggest that this metabolite does not enter the food chain.
