Abstract
2-AMINO-1,3-THIAZINES HAVING THE FORMULA ##STR1## wherein R.sup.1 is optionally substituted carbocyclic or heterocyclic aromatic and R.sup.2 is hydrogen, alkyl, alkenyl or optionally substituted substituted carbocyclic aromatic. The 2-amino-1,3-thiazines are useful for combatting fungi and bacteria, for example, in plant protection for combatting archimycetes, phycomycetes and the like, are prepared by reacting beta-halogeno-ethyl-ketone having the formula R.sup.1 --CO--CH.sub.2 --CH.sub.2 --Hal wherein Hal is halogen and R.sup.1 is as defined above, with thiourea of the general formula ##STR2## wherein R.sup.2 is as defined above.
