RECOMMENDED USAGE RESTRICTIONS FOR PLANT PROTECTION PRODUCTS ON
SOUTHERN AFRICAN EXPORT CITRUS
Vaughan Hattingh, Citrus Research International, tel 021-8828553, fax 021-8828557, [email protected] and Paul Hardman, Citrus Growers Association of southern Africa, tel 031-7652514, fax 031-7658029, [email protected]
The purpose of these restrictions is to ensure compliance with residue tolerances in the countries to which
Southern African citrus is exported. The recommendations on container labels are based on the current
registrations of plant protection products. In terms of the SA Act 36 of 1947 (and equivalent legislation in
neighbouring countries) the registration requirements must be adhered to at all times. However, the
requirements of importing countries have made it necessary to introduce further restrictions in order to
comply with maximum residue limits.
The active ingredients of the products are listed alphabetically together with an illustrative brand name. In
the case of commodity products which may be sold under different brand names only a single name is
shown for convenience. This does not imply endorsement of the particular brand concerned.
Due to the multiple fruit set pattern of lemons, plant protection products may only be used as specified during
the first spring blossoming and fruit set period. Special caution should be exercised to ensure that
pesticides applied to protect later sets do not result in unacceptable residues in fruit remaining on the trees
from earlier sets.

The following general statements are applicable to the use of plant protection products on all cultivars:
*
Growers should ensure that these restrictions are kept handy and are consulted before the application of plant protection products. The application in accordance with current label requirements will in many instances not ensure that export requirements will be met. The restrictions specified are applicable in addition to the label requirements. The withholding periods specified on product labels provide an indication of the ability of treatments to conform to South African residue levels. Since overseas requirements are generally more stringent these withholding periods are not adequate unless specifically mentioned in this document. These restrictions apply to the period during which fruit is present on trees (between blossom and harvest) and not to the period between harvest and the onset of blossom, during which time standard label requirements apply. All usages apply to normal blossom situations. Under conditions where blossoming occurs over an extended period a more conservative approach must be adopted. Under these conditions treatments should be timed according to the early portion of the blossom. Particular attention must be given to ensuring that spray machinery is calibrated to apply the correct spray volumes in relation to tree size and that spray operators are trained in the handling and application of plant protection products. All treatments referred to above must be applied at the registered concentrations. Alternation of products, where applicable with reference to the restrictions, will reduce the risk of excessive residues of any one chemical and will also reduce selection pressure for resistance. The additional restrictions in this document do not necessarily provide an indication of the compatibility of the products with integrated pest management and good agricultural practice. The addition of oil to a treatment, if not registered as such, should be avoided as this may increase the residue level.
All exporting growers should keep accurate spray records so that in the event of exceeding MRLs the
reasons can be determined. These records should be retained in safe-keeping for at least 3 years.
Growers are strongly urged to abide by these restrictions to minimise the risk of residue tolerances being
exceeded. However, it must be noted that no absolute guarantee can be given that even by following
these guidelines export residue tolerances will in all instances not be exceeded.
