Planting systems must allow safer, more efficient spraying practices to be adopted.

The use of non-naturally occurring synthetic plant growth regulators is generally not permitted. Their use can only be permitted when absolutely necessary in the following cases:

• Where excessive numbers of flowers have pollinated and set during blossom and an excessive crop is likely to result, the young fruitlets must be thinned shortly after blossom to the optimum number to ensure adequate fruit size and quality. Chemical thinning agents are permitted on specific varieties that have excessive blooming (only economically feasible approach).
• Conversely, where weather during blossom is unfavourable for pollination and set, sprays of naturally occurring (but chemically synthesized) crop setting agents (e.g. gibberellins, NAA) are permitted.

The use of non-naturally occurring, synthetic plant growth regulators as fruit finishing, coloring or ripening agents is not permitted. 

Regional or national IP guidelines must set out which chemicals are permitted, clearly specifying the aim and the restrictions of their use.
