Inclusion complex of a phosphorus-containing organic calcium compound and of cyclodextrin, process for its preparation and its use for protecting plants

摘要

The present invention relates to an inclusion complex of general formula (I): 1. Inclusion complex of general formula (I): <IMAGE> where CD is a group obtained by removing 1/n hydroxyl groups from a cyclodextrin molecule - preferably beta -cyclodextrin - and n is a value between 0.2 and 0.3, which is the inclusion complex of a complex of calcium bis[O-methyl O-(2,2-dichlorovinyl) phosphate] and of 2 moles of O,O-dimethyl O-(2,2-dichlorovinyl) phosphate formed with cyclodextrin, preferably with beta -cyclodextrin.
