Pesticide log book

If you use pesticides, it’s good practice to keep detailed records for future reference. Use our log book to note down what’s been applied, when and where.

Why keep records?

At present, only those applying pesticides to crops are legally required to keep a log. However, the Department for Environment, Food and Rural Affairs (Defra) advises all businesses to keep a record of what substances are used to restrict pests, weeds and diseases. This is largely in case of a complaint after the event. With the right paperwork you can quickly demonstrate that you took reasonable care. You can also use your records to evaluate the effectiveness of treatments.

Note. If you grow crops you’ll need a more detailed log book, the contents of which can be obtained from Defra.

What to include?

The term “pesticide” is all encompassing and covers all substances used to kill weeds, pests and moulds. You should use our log book each time that you apply these materials outside. If you use contractors, they should keep their own records, but there’s nothing to stop you asking them to complete yours as well for your own peace of mind.

One row of the form should be used for each treatment.

Ministerially Approved Pesticide Product (MAPP) or HSE numbers are unique product registration codes which show that the material has been approved for storage and use in the UK. They apply to all agricultural, horticultural and home garden products, so if your substance doesn’t have one it’s probably not legal.

Note. Substances approved before 1999 should have a Ministry of Agriculture, Fisheries and Food (MAFF) number instead.
