• Acceptable Daily Intake (ADI) “ADI” of a chemical is the daily intake which, during an entire lifetime, appears to be without appreciable risk to the health of the consumer on the basis of all the known facts at the time of the evaluation of the chemical by the Joint FAO/WHO Meeting on Pesticide Residues. It is expressed in milligrams of the chemical per kilogram of body weight.
  • Acceptable Operator Exposure Limit (AOEL) The maximum amount of active substance to which the operator may be exposed without any adverse health effects. The AOEL is expressed as milligrams of the chemical per kilogram body weight of the operator.
  • Acute Reference Dose (ARfD) An estimate of the amount a substance in food or drinking water, normally expressed on a body weight basis, that can be ingested in a period of 24 h or less without appreciable health risks to the consumer on the basis of all known facts at the time of the evaluation" (JMPR, 2002).


  • Contact herbicide Contact (non-systemic) means that the herbicide does not translocate within the plant, and affects only the parts of the plant where it is applied.


  • Hazard assessment Process that includes hazard identification and characterization and focuses on the hazard in contrast to risk assessment where exposure assessment is a distinct additional step
  • Herbicide-tolerant (HT) crops Crops that have acquired the ability to resist the effects of certain broad-spectrum herbicides. Some crops may have acquired that trait through selection or mutation; or more recently, plants may be modified through genetic engineering.


  • Maximum residue limit (MRL) Maximum concentration of a residue that is legally permitted or recognized as acceptable in, or on, a food, agricultural commodity, or animal feedstuff as set by Codex or a national regulatory authority.


  • No Observed Adverse Effect Level (NOAEL) In toxicology it is specifically the highest tested dose or concentration of a substance (i.e. a drug or chemical) or agent (e.g. radiation), at which no such adverse effect is found in exposed test organisms where higher doses or concentrations resulted in an adverse effect.
  • Non-selective (broad-spectrum) herbicide Herbicide that controls a broad spectrum of weeds in one treatment.


  • Plant protection products (PPPs) Plant protection products (PPPs) are the treatments used in both conventional and organic agriculture, to keep crops healthy by protecting them against pests and diseases. Also known as pesticides, PPPs are to plants the equivalent of medicines for humans. PPP companies manufacture synthetic products as well as products based on natural chemicals and minerals.


  • Residue (pesticide) Substance which remains in or on a feed or food commodity, soil, air, or water following use of a pesticide. For regulatory purposes, it includes the parent compound and any specified derivatives such as degradation and conversion products, metabolites, and impurities considered to be of toxicological significance.
  • Resistance (weed resistance) Inheritable ability of some pest biotypes within a given population to survive a pesticide treatment that should, under normal use conditions, effectively control populations of that pest.
Pesticide residues in food: risk to consumers remains low

The latest monitoring report published by the European Food Safety Authority (EFSA) concluded that food consumed in the European Union continues to be largely free of pesticide residues or to contain residues that fall within legal limits. More than 97% of food samples collected across the EU in 2015 were within legal limits, with just over 53% free of quantifiable residues. The figures are in line with those recorded in 2014.

What is the current status of registration of Glufosinate-ammonium in the EU?

The current EU registration for Glufosinate-ammonium is valid until 31 July 2018. Bayer believes that there are solid arguments for a re-approval of Glufosinate-ammonium after.
