The tests shall provide sufficient data to permit an evaluation of the possible occurrence of taint or odour or other quality aspects of plants or plant products after treatment with the plant protection product.
The possibility of the occurrence of taint or odour in food crops must be investigated and be reported where:
the nature of the products or its use is such that a risk of occurrence of taint or odour might be expected,
or
other products based on the same or a closely similar active ingredient have been shown to present a risk of occurrence of taint or odour.
The effects of plant protection products on other quality aspects of treated plants or plant products must be investigated and reported where:
the nature of the plant protection product or it use could have an adverse influence on other quality aspects (for example in the case of use of plant growth regulators close or harvest), or
other products based on the same or a closely similar active ingredient have been shown to have an adverse influence on the quality.
Testing should be conducted initially on the main crops on which the plant protection product is to be used, at twice the normal rates of application and using, where relevant, the main methods of processing. Where effects are observed it is necessary to perform testing at the normal rate of application.
The extent of investigation necessary on other crops will depend on their degree of similarity of the main crops already tested, the quantity and quality of data available on those main crops and how far the manner of use of the plant protection product and methods of processing the crops, are similar. It is generally sufficient to perform the test with the main formulation type to be authorized.
The tests shall provide sufficient data to permit an evaluation of the possible occurrence of adverse effects after treatment with the plant protection product on transformation processes or on the quality of their products.
When the treated plants or plant products are normally intended for use in transformation process such as wine making, brewing or bread making and when at harvest significant residues are present, the possibility of the occurrence of adverse effects must be investigated and reported where:
there are indications that the use of the plant protection product could have an influence on the processes involved (for example in the case of use of plant growth regulators or fungicides close to harvest),
or
other products based on the same or a closely similar active ingredient have been shown to have an adverse influence on these processes or its products.
It is generally sufficient to perform the test with the main formulation type to be authorized.
The test shall provide sufficient data to permit an evaluation of the performance of the plant protection product and of possible occurrence of yield reduction or loss in storage of treated plants or plant products.
The effects of plant protection products on the yield or yield components of treated plant products must be determined where relevant. When treated plants or plant products are likely to be stored the effect on the yield after storage, including data on starage life must be determined where relevant.
This information will normally be available from the tests required under the provisions of point 6.2.]
