Among them, 3-phenyl, 3-(2-substituted phenyl), and 3-(2,4 dichlorophenyl) derivatives were found to show not only a broad herbicidal spectrum against several weeds, but selective activities to such crops as rice, corn, wheat, and soybean. In addition, their activities as photosynthesis inhibitors were evaluated by a oxygen electrode method.}, pages = {42--48}, title = {<一般論文>Pyridazino〔4,5-e〕-1,2,4-triazineの誘導体の合成と除草作用}, volume = {36}, year = {1987} }
