Use of Cultar
More Information

May I use Cultar in my pecan nut orchard in South Africa?

Yes you may use Cultar but are cautioned to consider all the facts before you continue or start using it.


Cultar (Paclobutrazol) and some other brand names with the same active ingredient, are currently registered for use on pecan nut trees in South Africa. The product is widely used and has been for some time. The merits or demerits of the substance is not what is discussed here but rather the risks that are involved.

As part of risk managementthe pecan nut producer has to consider that the product is not registered in the USA. The reason for this is that it can be traced in the soil for several years after application and the USDA does not register such products. There could be a scenario where customers refuse to purchase pecans where Cultar has been applied or where traces can be found, leaving South African producers using Cultar, at risk of losing access to these markets.

MRL analysis and the means to test product for traces or residues of almost anything is real and this ability is only heightening.

SAPPA has an obligation to provide guidance and foresight to pecan nut producers to make informed and enlightened decisions timeously.

It needs to be understood is that it is ultimately the buyers who decide to buy or not to buy any product.

It is therefore recommended that producers should not start using Cultar and those that are using it should consider stopping the use thereof.

It remains the producer’s prerogative to use Cultar with acknowledgement of the risk.
