We advise that you avoid all pesticides unless they are certified or approved for organic use.
There are thousands of different substances that are used in agricultural land management, but in terms of chemicals available to individuals that are still sold in garden centres, there are a few notable ones that you can look out for and avoid: ‘glyphosate’, ‘2,4-D’, ‘MCPA’, ‘acetemiprid (neonicotinoid)’, ‘pyrethroids such as cypermethrin and deltamethrin’ and ‘metaldehyde’, to name a few.
