Dichloropyrazino-oxazines of the formula STR1 wherein R is H or a C1 to C8 alkyl, alkenyl, cycloalkyl or cycloalkenyl radical, are disclosed. The compound in which R is H has utility as an intermediate for the compounds in which R is other than H. The latter compounds exhibit microbicidal, herbicidal or insecticidal activity. The compounds of the invention are readily prepared from tetrachloropyrazine and 2-aminoethanols of the formula R--NH--CH2 CH2 --OH.
