PURPOSE: The titled preparation that contains a clathrate of 1,3-dichloropropene with a cyclic dextrin as an active ingredient, thus showing insecticidal and nematocidal activity for a long period of time with less irritant odor, no harm to human bodies and no damage to crops, further being easy-to-handle.
CONSTITUTION: The titled preparation contains a clathrate of 1,3-dichloropropene with a cyclic dextrin. As a cyclic dextrin, is preferably used β-cyclic dextrin containing 7 bound glucose molecules from economic point of view. The clathrate is prepared, e.g., by mixing an aqueous saturated solution of cyclic dextrin with 1,3-dichloropropene thoroughly, separating the resultant precipitate and drying it by standing or under reduced pressure. 1,3-dichloroprpene may be a mixture with 1,2-dichloropropane, a by-product, as well as a pure product.
