Since 1992 an increased number of outbreaks of potato brown rot, caused by the bacterium Ralstonia (Burkholderia, Pseudomonas) solanacearum race 3, biovar 2, has been reported in several EPPO member countries, including more northern states like Belgium, France, The Netherlands and the UK. The largest outbreak took place in The Netherlands in 1995, mainly through one heavily infected seed‐tuber line. The bacterium was found in most infested countries in surface water and in the weed Solanum dulcamara growing along waterways. In some countries, tomato was also found to be infected. The history of the so‐called‘low‐temperature’race 3, adapted to more temperate climates (also occurring at higher altitudes in the tropics) is described, together with details on its host range and geographical distribution. Possible origins of the disease in western Europe are discussed, including introduction through import of infected early ware or industrial potatoes from some countries in the Mediterranean area, where the disease is established. The brown rot bacterium has many similarities concerning its biology and epidemiology with some other infectious diseases, e.g. with cholera, and useful comparisons can be made for control strategies. A detailed account on the epidemiology of P. solanacearum and possible prevention and control strategies is presented. These strategies are: (1) responsibility for prevention and control is for the country where the disease occurs; (2) countries where the disease occurs should report outbreaks as soon as possible; (3) early and sure detection and diagnosis of the pathogen are the core of the system; (4) adequate prevention and control measures should be taken after an outbreak; (5) production of healthy seed tubers should be guaranteed and surveys and (laboratory) checks for (latent) infections performed; (6) education of scientific personnel and the public (farmers, traders, advisory service, etc.) is essential. It is foreseen that hygienic measures and avoidance of surface water for irrigation will be key factors in successful control of the disease.

“…These amendments serve the dual purpose of improving soil fertility and reducing the nematode population through the increase of soil microfauna (Poswal & Akpa 1991;Agbenin 2004). In Nigeria, success in nematode disease management was recorded using poultry manure, cow dung and sawdust (Babalola 1982;Chindo et al 1991). In Egypt, Korayem et al (2008) reported the effectiveness of chitins and abamectin in reducing the root-knot problem in oil seed rape in the field.…”

Agbenin N.O. (2011): Biological control of plant parasitic nematodes: prospects and challenges for the poor Africa farmer. Plant Protect. Sci., 47: 62-67.Africa contains a larger part of world's developing countries with their associated problems of food security and healthy environment. Pollution and its grave consequences are among the greatest challenges of the tropics and affect the choice of management strategies in agriculture. Biocontrol as an integral part of management is an attractive option for plant parasitic nematodes that should be pursued besides the cultural practices of crop rotation and organic amendment to include the use of microorganisms isolated, cultured and packaged in the tropics for tropical farmers. Exploring biocontrol in nematode management is yet unattainable for the tropical farmer, not until research and manpower development in this area are encouraged by both governments and donor agencies.

“…The two often infect tomato simultaneously, forming a complex that increases the incidence and severity of Fusarium wilt (Onkendia, Kariuki, Marais & Moleleki, 2014). A study by Chindo, Khan and Erinle (1991) revealed that the presence of Meloidogyne spp greatly reduced resistance of tomato cultivars to the fusarium wilt. The presence of fungal survival structures (chlamydospores) that enhance its ability to persist in the soil for a long time and its wide host range makes its management fairly challenging (Blum & Rodriques, 2004;Sudhamoy, Nitupama & Adinpunya 2009;Moretti, Gilardi, Gullino & Garibaldi 2008).…”

Tomato plays a critical role in meeting nutritional food requirements, generating income and creating employment for both the rural and urban populations in Kenya. However, its production is threatened by the Fusarium wilt caused by Fusarium oxysporum f.sp. lycopersici, root knot nematodes (Meloidogyne spp), Fusarium wilt-root-knot nematode complex and Tomato leaf miner (Tuta absoluta) among others. Yield losses of 80-100% in some instances, have been reported due to the Fusarium wilt -root knot nematode complex. Field experiments were set up in two sites (Kagio and Mwea) in Kirinyaga County in Central highlands of Kenya to evaluate the effectiveness of various Integrated Pest Management (IPM) packages for the management of fusarium wilt-root knot nematode disease complex in tomatoes. The trials were established in two seasons, the long rains (March -July 2016) and the short rains (September 2016-January 2017). The IPM packages tested were NatuGro system (a combination of soil improvers, plant biostimulants and Trichoderma harzianum T22), a fungicide (carbendazim), Nemix (Bacillus sp. based biocontrol agent) and bionematicide (Paecilomyces lilacinus T251) applied either singly or in combination. Root knot nematode (RKN) gall index, as a measure of nematode disease severity was assessed twice during the experimental period; at flowering and mid fruit stage, while severity of fusarium wilt was assessed using the vascular wilt rating scale of 0-5. Fusarium wilt incidence was evaluated biweekly from 2 weeks after transplanting by visual assessment of wilt symptoms and expressing them as a percentage of total number of plants per plot. Both total and marketable tomato yields were determined at the end of the experimental period (4 months after transplanting). Integrating NatuGro system, Carbendazim and P. lilacinus was most effective in reducing RKN disease severity and damage and improving tomato growth followed by NatuGro system applied singly. Fusarium wilt severity and incidence were low throughout the experimental period and in all the treatments in both experimental sites.
