Displaying 3 results of Pyrimethanil Stable Isotopes Pyrimethanil stable isotopes are non-radioactive forms of the fungicide pyrimethanil, which is used to control fungal diseases in crops. These stable isotopes are used in research to better understand the metabolism and fate of pyrimethanil in the environment. They can also be used in analytical chemistry to identify and quantify pyrimethanil residues in food and soil samples. Pyrimethanil stable isotopes provide a valuable tool for scientists and regulators to ensure the safe and effective use of this important fungicide.
