Guide to pesticides best practice

by Sarah Coe Natural Resources Wales

PESTICIDES are an integral part of modern farm management – they help farmers to manage even the very basic of crops to ensure a good, healthy yield. Whether to feed your stock or to sell directly to market, pesticides reduce the risk of crops being decimated. Pesticides are extremely effective – meaning that if they get into local waterways and rivers they can cause significant damage to the insects that live there.

There are some changes to legislation in term of cross compliance and grandfather rights farmers will need to be aware of this year and they can find out more from the Welsh Government. There are things to remember like checking for any restrictions on applying pesticides to the land in question, check the code of good agricultural practice (CoGAP), Cross Compliance or Glastir scheme requirements and ensure the operator is competent and has appropriate certificates.
