The present invention relates to novel pyridazine derivatives of formula (I) as active ingredients which have microbiocidal activity, in particular fungicidal activity: formula (I) wherein R1 is C1-C6alkyl, C1-C6haloalkyl or C3-C6cycloalkyl; R2 is hydrogen or an optionally substituted alkyl, aryl or heteroaryl; R3 is hydrogen, C1-C6alkyl or C1-C6haloalkyl; R4 is hydrogen, C1-C6alkyl or C1-C6haloalkyl; or R3 and R4 together can be part of a carbocyclic or heterocyclic 3- to 8-membered ring; R5 is optionally substituted aryl or heteroaryl; and R6 is hydroxy, halogen, C1-C6alkoxy, C1-C6haloalkoxy, C1-C6alkylthio or C1-C6haloalkylthio; or an agrochemically usable salt form thereof.
本发明涉及式(I)的新型吡嗪衍生物,其作为活性成分具有微生物杀菌活性,特别是杀真菌活性:式(I)其中,R1是C1-C6烷基,C1-C6卤代烷基或C3-C6环烷基;R2是氢或可选取代的烷基,芳基或杂环芳基;R3是氢,C1-C6烷基或C1-C6卤代烷基;R4是氢,C1-C6烷基或C1-C6卤代烷基;或R3和R4可以成为碳环或杂环3-8元环的一部分;R5是可选取代的芳基或杂环芳基;R6是羟基,卤素,C1-C6烷氧基,C1-C6卤代烷氧基,C1-C6烷基硫醚或C1-C6卤代烷基硫醚;或其农药可用盐形式。
