Pyridafol is present in fungicide, herbicide and pesticide mixtures used to treat weed growth among agriculture.

The commercial synthesis of pyridafol involves a multi-step process starting with 3-chloro-5-methoxy-6-phenylpyridazine, which undergoes demethylation and hydrolysis to yield the active compound. The process typically uses reagents like sodium hydride or zinc in solvents such as isopropanol, with moderate yields.
