PURPOSE: An agent for thinning flowers of fruits trees that contains a phospholipid as the effective ingredient, thus being harmless and selectively letting flowers fall down. n CONSTITUTION: As the effective ingredient is added usually 0.1W5, preferably 0.4W3 wt% of a phospholipid, preferably lecithin. The agent is applied in the period from three weeks before blossom to flower dropping to almost all fruit trees as pear, peach, persimon and others. The action to drop flowers is caused by the weakly physiological activity and physical and chemical properties of the phospholipid. n COPYRIGHT: (C)1980,JPO&Japio |
