Currently authorised (extant) plant protection products(PPP)
Extensions of authorisation, adjuvants and basic substances
A basic substance is a commonly available commodity which has been assessed as acceptable for specific plant protection purposes. Examples of basic substances include sucrose, calcium hydroxide and vinegar.
Basic substances must not be sold as a PPP nor can they be labelled with any plant protection claims or the uses approved at a GB/NI level. Growers may however purchase these commodities and use them in accordance with the approved conditions of use. No separate authorisation for the use is required.
Full details of the currently approved active substances (chemical, low-risk and basic) including the review report can be found on the GB/NI Pesticides Database.
Basic substances must not be confused with products containing low-risk active substances which need to be evaluated and authorised in the usual way. Further information on Low-Risk and Basic Substances.
