Southern Africa: Armyworm Infestation - Jan 2017Ongoing
Reports from the Zambia Disaster Management and Mitigation Unit indicate that as of 9 January 2017, close to 130,000 ha planted to maize had been affected by a severe outbreak of the Fall Armyworm, which is new to the southern African region. Of the affected area, over 68,000 ha may require re-planting. Government efforts to control the outbreak are underway...With 94% of the country’s districts affected in varying degrees, including several districts bordering Zambia’s eight neighbours in the SADC region, vigilant region-wide monitoring activities are required. (SADC, 13 Jan 2017)
A fall armyworm outbreak, the first emergence of the pest in southern Africa, is causing considerable crop damage in some countries. If the pest damage aggravates, it could dampen prospects for good crop harvests that is anticipated in the current farming season. Maize, a staple food in the region, has been the most affected, as well as other cereals including sorghum, millet and wheat. Southern Africa is reeling from the effects of two consecutive years of El Niño-induced drought that affected over 40 million people, reduced food availability by 15 percent and caused a cereal deficit of 9 million tonnes.

Sixteen East and Southern African countries agreed on 16 February on urgent plans of action aimed at boosting the region’s capacity to manage emerging crop pests and livestock diseases, including armyworm and avian influenza ... Zambia has reported that almost 90 000 hectares of maize have been affected, forcing farmers to replant their crops. In Malawi some 17 000 hectares have so far been affected while in Namibia, approximately 50 000 hectares of maize and millet has been damaged and in Zimbabwe up to 130 000 hectares could be affected thus far.

The first 20 days of April saw an increase in rainfall in Botswana, Lesotho, Namibia, and South Africa, after a relatively dry March. Rainfall tapered off in late April, although some areas in Zimbabwe and central Mozambique received higher than usual rainfall amounts for this time of year ... The excessive rainfall in some areas also appears to have helped suppress the impact of the fall armyworm, a new pest which has invaded 11 SADC countries. (SADC, 28 Apr 2017)
Preliminary assessments, conducted between mid-February and the end of April 2017, showed that approximately 356,000 hectares of crops were affected by the fall armyworm infestation in seven reporting Southern Africa Development Community (SADC) member states: Botswana, Democratic Republic of the Congo, Malawi, Namibia, South Africa, Swaziland and Zambia.

Erratic rainfall, high temperatures and persistent Fall Armyworm infestation lower cereal crop production prospects for 2018 in southern Africa. (Food and Nutrition Security Working Group Feb 8 2018)
Countries with confirmed outbreaks can face import bans on their agricultural products because armyworm is classified as a quarantine pest
CAPE TOWN, Nov 9 (Reuters) - South Africa has managed to control an outbreak of fall armyworm pests, which were first detected in January and mainly threatened maize crops, the agriculture minister said on Thursday.

Pretoria – As the Western Cape faces a serious drought due to poor rainfall during winter, the Department of Water and Sanitation has informed the agricultural sector of 10 percent additional water restrictions.
The demand for water in the province has steadily increased due to the growing population and economy. This, as well as poor rainfall, has added significant pressure on water supply.

Ladies and gentlemen,
Thank you for your presence.
The Department of Agriculture, Forestry and Fisheries (DAFF) today received a diagnostic report from the Agricultural Research Council, Plant Protection Research Institute (ARC PPRI) to confirm that the Fall Army Worm was positively identified from samples collected in the Limpopo Province. The samples were jointly collected by scientists from the ARC Grain Institute and the North West University. These were caterpillars that had to pupate and emerge as moths before a positive identification could be done.
