Know Your Chemicals!

In view of legal and political changes regarding garden chemicals, GN sheds light on the subject

Last week we explained what’s planned in future by the government for our most commonly used garden herbicides, and which products can still be used. This week we tackle pesticides, which includes molluscicides, and fungicides.

It’s no surprise that gardeners are confused and uncertain about certain products and what the future might hold, particularly after Britain leaves the European Union, but remember that all garden chemicals currently on sale have been passed as being legally fit for purpose by EU agreements, overseen in the UK by the Chemical Regulation Directorate.

The use of any type of pesticide or fungicide is a matter of personal preference and belief, but all products should be used with care and according to manufacturers’ instructions. Only make or use as much as is required for the job, specifically targeting rather than broadcasting their use wherever possible. Ensure any residues and redundant products are disposed of carefully and stop using products that are withdrawn for legal reasons after any designated ‘use up’ period has expired.

Try to maintain an integrated approach to pest and disease control, using disease-resistant varieties and maintaining plant health through good husbandry.

PESTICIDES

Pesticides, specifically those used to kill plant pests such as insects and mites, is the group of garden chemicals experiencing the greatest overhaul and change, with more products containing natural or ‘organic’ active ingredients being made available.

Synthetic systemic pesticides

These broad-spectrum, nonnatural substances kill by being absorbed into plant tissues and ingested by the organism.
