An agent for suppressing pollen dispersal, containing an oleic acid derivative or a linoleic acid derivative as an active ingredient, which does not influence the trunk, branches and leaves of trees, shows a sharp efficacy on the male organ and is in the form of a solution or emulsion having solution stability by diluting with water.
Claims7
A method for suppressing pollen dispersal, comprising spraying or applying to a male organ of a tree an effective amount of an oleic acid derivative or linoleic acid derivative represented by the following formula (I)
- wherein R1 are residues of an oleic acid ester or a linoleic acid ester, which may be of the same kind or different kinds, O—R2 are oxyalkylene groups having a carbon number of 2 to 4, which may be of one kind of two or more kinds, and when they are of two or more kinds, they may be block adducts or random adducts;
- j and k are 0,
- X is a polyvalent organic group having a carbon number of 4 or more,
- 1 is 0,
- n is 2 or 3, and
- m+n is 3, 4, 5, or 6, thereby suppressing pollen dispersal.
