Abstract
PURPOSE: After seeds and seedlings are treated with an aqueous folic acid, said high-selectivity herbicide containing novel dicyanopyrazine as the effective ingredient is applied to rice paddies and fields, thus strongly whitening and killing annual and perennial weeds.
CONSTITUTION: More than 0.5 wt%, preferably 1-99wt% of a compound of formula I (R is ethyl, n-propyl) is included to make a dust, or granule, or wettable powder preparation, which used as herbicide. The compound of formula I is prepared by, e.g., reaction of a compound of formula II (X is halogen with an amine. Said herbicide can selectively whiten and kill only weeds when applied to rice paddies and fields in either way of treating soil or spraying on stems and leaves. Further, when the seeds or seedlings of useful plants is made to absorb folic acid, their resistance to whitening is increased and the reduction of the selectivily of said herbicide can be prevented even under bad conditions.
