SGS Brookings continues expanding its scope of services in order to meet the growing demand for independent pesticide residue testing. SGS conducts pesticide residue testing on leaf tissue and soil that may have problems caused by the use of an incorrect product, chemical drift, or by environmental changes that have impacted plant reaction.

SGS offers individual or package testing of common pesticides including plant growth regulators, soil applied or pre-emergent herbicides, Sulfonylureas, Imidazolinones, Clethodims, Aminopyralid, Glyphosate, Glufosinate, Flumioxazin, and a fungicide screen of pesticides.

SGS also offers an informative webinar to help determine testing strategies for pesticide drift. This webinar walks you through the process of gathering information on the crop situation, setting up a testing strategy based on current knowledge, and submitting the sample to the laboratory for analysis to yield valid results.

Sample turn-around time ranges from 5-10 days with more chance of delays during the heavy season of August and September.

SGS is an ISO17025 accredited scientific laboratory offering a broad range of testing solutions on feed, grain, food, plants, co-products and seed. Our scientists are highly-trained, and they utilize the latest in technology to deliver fast, accurate and independent verifications.
