A new method is described for examining the chemical nature of a pesticide as a granular formulation. A screening program revealed that β-nitrostyrene was highly active against soybean root knot nematode but a granular formulation was completely inactive. Solid-state (CPMAS) 13C NMR spectroscopy of a granular formulation prepared with 13C-labeled active ingredient led to identification of the inactive form as a polymer of the active ingredient. Initiation of polymerization by the clay granule carrier was confirmed.
