Method of improving the pickability and the ripening of fruit, and preparation for use in this method

摘要

The invention relates to method of improving the pickability and ripening of fruit. For this purpose fruit trees, fruit shrubs or fruit are treated with a preparation which contains the substance 4-oxyacetic acid-5-methyl-7-chlorobenzthiadiazole-2,1,3 as the active constituent. This treatment preferably is effected a few weeks prior to harvesting. In particular the treatment of citrus fruit with an aqueous dispersion which contains from 100 to 2000 mg of active substance per liter provides good results. The citrus fruit is readily detached and shows improved ripening, for example an appreciable improvement in color.
