The Western Cape provincial government, through the department of agriculture, has invested R2 million in the citrus industry. This will be given to the local growers for pest control to ensure that farmers are able to protect their produce.
The department said the initiative was done to safeguard the export fruit industry from pests, and that the funds are aimed at helping farmers deal with pesticides using the sterile insect technique (SIT) for false codling moth (FCM).
The SIT programme is delivered by X Sterile Insect Technique (X-SIT), forming part of the RBX Group, and is a subsidiary of the Citrus Growers Association of Southern Africa (CGA).
Quality assurance key
“The RBX Group develops, supplies and supports sustainable crop protection products that assist in keeping export crops free of pests so that they can meet international phytosanitary regulations and food safety requirements. X-SIT helps to retain international market access for a critical sector of the South African economy,” the department stated.
According to data from the government, the Western Cape alone exports approximately 20 million 15kg cartons of citrus per season, generating a substantial amount of revenue and supporting approximately 30 000 jobs in the province. The citrus industry as a whole sustains the livelihoods of 140 000 South Africans.
“The sterile insect technique used by X-SIT is a sustainable and environmentally safe practice that does not make use of any pesticides. In combatting FCM, the practice involves rearing large numbers of male and female moths, sterilising them by exposure to radiation and then releasing them into the orchards.
“When the sterile moths mate with wild moths, the eggs that are produced are not viable. This leads to a huge reduction in the FCM population over time,” the department said.
Hannes de Waal, chairman of the CGA, welcomed the support from the provincial government for the programme and believes that the initiative would go a long way in ensuring that farmers are able to produce the best fruit that is needed by the international market
“We are truly grateful to the Western Cape department of agriculture, projects such as this are important in keeping key markets like Europe and the United States of America open to producers. We are proud to contribute to communities through both job creation and environmental preservation,” he said.

A prized commodity
The Western Cape minister of agriculture, Dr Ivan Meyer, said his department’s support gives access to citrus growers who find the SIT programme unaffordable, supports compliance with export requirements, and protects jobs within the citrus industry.
“The citrus industry plays a critical role in the fruit and export basket of the Western Cape, and job creation and economic development in the province.”
“The sterile insect technique is a proven intervention, as research has shown that it reduces fruit infestation and export rejections, and reduces the risk of fruit destined for export being rejected by the importing country,” he said.
Not limited to citrus
Meanwhile, the department said the SIT programme supports 140 jobs and is not only used for citrus crops. Currently, it is used on 19 500 hectares of varied crops, including table grapes and stone fruit. The facility in Citrusdal has the potential to increase this to over 40 000 hectares.
De Waal is hopeful about the future. “SIT programmes around the world are rather expensive but serve as a critical base for a more sustainable Integrated Pest Management approach to key pest control.
“We hope support will continue and encourage other funders to realise the importance of the Sterile Insect Technique in export crop protection,” he said.
