PS/5-17458/+ Compositions for protecting plants against disease Novel benzo-1,2,3-thiadiazole-7-carboxylic acid esters of formula (I) in which Y is oxygen or sulfur; Q1 and Q2 independently of one another are each hydrogen or halogen; R1 and R2 independently of one another are each hydrogen or C1-C4alkyl; X1 is hydrogen, halogen, C1-C4alkyl, trifluoromethyl, C1-C3alkyl, C1-C2-alkoxy halo-substituted in the alkyl moiety, nitro, cyano, dimethylamino, phenyl, phenoxy, or phenyl. or phenoxy each substituted by halogen and/or by C1-C2alkyl and/or by C1-C2alkoxy; X2 is hydrogen, halogen or methyl; X3 is hydrogen or halogen; and A comprises the bridge members , , carbonyl, ethenylene and ethynylene, wherein R3 is C1-C6alkyl, C3-C6alkenyl, hydroxy, C1-C6alkoxy, O-C(O)-C1-C4alkyl, carboxy, COOC1-C4alkyl, cyano or hydrogen, with the proviso that is R3 is hydrogen R1, R2 or R4 is not simultaneously hydrogen; R4 is C1-C6alkyl, C1-C6alkoxy or hydrogen, with the proviso that if R4 is hydrogen R1, R2 or R3 is not simultaneously hydrogen; R5 is C1-C6alkyl, C3-C6cycloalkyl, C1-C6alkoxy, phenyl, or phenyl substituted by halogen or methoxy; R6 is C1-C6alkyl or C1-C6alkoxy; or alternatively A represents the bridge member , that together also represents a saturated or unsaturated 3- to 7-membered carbocycle W1 or a saturated or unsaturated 5-to 7-membered heterocycle W2 having 1 or 2 hetero atoms that are either oxygen, sulfur or nitrogen; or the bridge member , that together represents a saturated or unsaturated 3- to 7-membered heterocycle W3 having a maximum of 2 oxygen or sulfur atoms as additional hetero atoms. The novel active ingredients have plant-protecting properties and are suitable especially for the preventive protection of plants against attack by phytopathogenic microorganisms such as fungi, bacteria and viruses.
