Abstract

PURPOSE: To prepare the titled herbicide effective to suppress and exterminate various weeds, nevertheless almost free from phytotoxicity against the crop such as rice plant, and applicable to farmland as well as nonfarmland, by using a pyrazolo. pyridazine derivative as an effective component.
CONSTITUTION: One or more pyrazolo.pyridazine derivatives of formula I [R is lower alkyl; X is H, halogen or lower alkyl; (n) is 1 or 2], e.g. 1H-5-methyl-3- phenyl-pyrazolo-[3,4-d]pyridazin-4(5H)one, are used as effective components. The component is combined with proper inert carrier, e.g. a solid carrier such as clay, or a liquid carrier such as water, alcohol, etc. by known procedure to obtain an easily handleable agricultural and horticultural herbicide of the form of wettable powder, flowable, dust, etc. The compound of formula I can be prepared by reacting the compound of formula II (Y is halogen) with potassium thioacetate in an inert solvent under reflux, and hydrolyzing the resulted compound of formula III.
