Welcome to our Website

Our Services

We provide testing services for a very wide range of pesticides enabling you to clearly identify the presence or not of residues.

Within the website we provide clear means of identifying pesticide types, that is their class and compound along with trade names, risks associated with use and contact and what they are commonly used on or to control.

Please feel free to contact us on 01732 876705 both within the United Kingdom and internationally. Alternatively we can be contacted by email or using the form that you will find at the base of most of our pages.

Modern agriculture has evolved to the extent that consumers now expect to be able to buy a plentiful supply of food, at a reasonable price, throughout the year.

Farmers and growers often use pesticides to help them achieve this goal.

However, the compounds used as pesticides for killing weeds, pests and moulds in crops are often harmful to people, wildlife and the environment. For this reason the sale and use of such compounds is very carefully controlled.

The authorisation of pesticide use is based upon Good Agricultural Practice (GAP). Yet it is recognised that, even use of GAP may still result in a crop with a detectable pesticide residue. Authorisation for the use of a pesticide is only approved if a risk assessment of residues levels in the crop shows the consumer risk is acceptable. Maximum residue levels (MRLs) for individual crop/pesticide combinations are therefore set on the basis of GAP.

The Maximum (pesticide) Residue Levels allowable in foods are therefore extensively regulated and frequently redefined in both EU legislation and Codex.

The latest annual report PRC 2006 Annual Report (pdf) from the UK government sponsored monitoring programme indicated that in the 3562 (2005 - 3787, 2004 - 3854) food samples analysed:

  • no pesticide residues were detected in 65.2% of samples (2005 - 68.1%, 2004 - 69%)
  • pesticide residues were detected below the MRL in 33.1% of samples (2005 - 30.2%, 2004 - 30%)
  • pesticide residues above the MRL were detected in 1.7% of samples (2005 -1.7%, 2004 - 1%).
