Pesticide Degradation Curve

AGQ USA has over 10 years of experience with developing pesticide degradation curve studies for our customers.   Pesticide degradation curve studies are used to monitor how pesticides degrades over time.

Why do a pesticide degradation curve study? 

Maximum residue limits (MRLs) are the maximum amount of a pesticide residue allowed on food.   Pesticide residue levels are affected by numerous factors such as the crop's growth rate, amount of rain, UV, and microorganisms.  In the U.S., pesticide labels all have crop specific preharvest intervals (PHI) that specify the amount of time after application that must elapse before the crop can be harvested to ensure that crop pesticides are below the MRLs.  These PHIs are based primarily on the crop MRLs in the U.S. and therefore the only way for U.S. exporters to ensure they meet foreign market MRLs is to test their product.   Additionally, many pesticides are mixed together before they are applied onto the crops that can have an amplification effect on the pesticide residues.  By performing a pesticide degradation curve study, growers can better understand their risk with using pesticides that have more restrictive MRLs in a foreign market they will be exporting to.
