The basic requirements of Good Agricultural Practice (GAP) with respect to the operation and maintenance of spray equipment must be fulfilled and outlined in IP guidelines.
The equipment must be kept in a good state of repair. Adequate functioning of the equipment must be verified before each treatment. A thorough technical service of the equipment, (especially manometers and nozzles), should follow the national rules and obligations.
Equipment must be verified every 4 year (3 years from 2021) or according to the national guidelines by a competent organisation for correct operation and calibration.
The use of aircraft and helicopters is forbidden, except for situations where access to the plot is impossible because of exceptional weather conditions, or if plot topography allows no other way of spraying.
Radial flow air assisted sprayers traditionally used for tree and bush fruit spraying are often inefficient and generate high levels of spray drift. Wherever possible spraying equipment and spraying conditions minimising the health risk of the operator and drift must be preferred and tractors must be fitted with a cab.
The spray impact on the environment can be minimised by the proper calculation of the amount of product needed per ha.
