The present invention relates to novel pyridazine derivatives of formula (I) wherein R
1
is methyl or ethyl; R
2
is H or chloro; R
3
is fluoro or chloro; R
4
is fluoro or methoxy; and R
5
is chloro or methoxy or an agrochemically usable salt from thereof, as active ingredients which have microbiodidal activity, in particular fungicidal activity.

without the necessity of carbonyl group protection/deprotection steps. Compounds 8–11 were also synthesized by an alternative method that utilized α-haloalkynes previously obtained directly from TMS-protected 4-RCOC6H4C≡CTMS alkynes. The resulting diynes were characterized by spectroscopic methods and in most cases by X-ray crystallography. Careful analysis of the crystal data revealed a surprisingly
