TK Formulators provides high quality formulation and packaging services for companies marketing crop protection products to the agricultural industry in the San Joaquin Valley of Central California and surrounding areas.

An experienced team of 65 employees operates herbicide, insecticide and fungicide plants where the formulation of liquid and granular herbicides is conducted in a completely separate area from all insecticide and fungicide production.

A fully equipped and staffed QA laboratory is capable of complex analysis of active ingredients, heavy metals and moisture content by liquid or gas chromatography, atomic absorption (AAS) and coulometric titration (Karl Fisher) methods.
