The pack size of all amateur products must be limited to the maximum that would be used in a typical garden in one season. This will help to ensure that most products are used up within 1 or 2 seasons.
The size and construction of a large UK garden is taken as follows:
When submitting an application for a new product, you must justify the maximum pack size by considering the uses proposed (in terms of application rates/number of applications) and the above assumptions on typical areas treated.
If you wish to seek a derogation from these maximum pack size restrictions, you must submit a reasoned case with your application which we will consider on a case-by-case basis..
We encourage authorisation holders to make available at least one smaller pack size to cater for small gardens.
For existing products which do not comply with these guidelines, the new pack size limitations will be introduced whenever you apply for significant changes to an authorisation which require technical evaluation. The arrangements will not be applied when the amendment sought is administrative, such as a name change for the product. Otherwise, new pack size limitations will be introduced for all remaining products at re-registration after the active substance is approved under (EC) No 1107/2009.
We discourage 2-for-1 offers on amateur products where this would exceed the maximum pack size allowed for use in a typical garden in 1-2 seasons. However, if the product types in a 2-for-1 offer are different, eg a weedkiller and a fungicide, then this would not be acceptable.
Bulk sales, such as buying 2 of the same product for a lower price than buying them individually, is acceptable if the maximum pack size for one season's use is not exceeded. For example, offers on buying 2 ready to use 1 litre products for a lower combined price than normally buying them individually would be acceptable, where the maximum permitted pack size is 3 litres.
Bulk sales on concentrates are generally discouraged as they are likely to lead to gardeners buying more than the maximum allowed for 1-2 seasons use.
You must ensure that special offers should not breach the principle that the total quantity of the same or similar products sold, should not be more than would have been permitted as a single pack representing 1-2 seasons use.
The crop or ground coverage provided by each pack size (eg 'treats x square metres') should be clearly stated on the main area of the label.
