Sixteen tomato cultivars obtained from the collections of the Institute for Agricultural Research (IAR) Samaru, Nigeria were screened for resistance to local strains of Tomato leaf curl virus at Samaru, Northern Guinea Savanna, over a two year period, 1998/1999 and 1999/2000 dry seasons. Five cultivars were moderately resistant, nine were moderately susceptible, while two were highly susceptible. Most of the cultivars were high yielding (46–55 t/ha) and had good fruit size (4.8–6.0 cm x 2.8–4.1 cm). They will be further evaluated on-farm at different locations after which they will be introduced to farmers to replace the low yielding and TLCV-susceptible cultivars currently in use in most parts of the Savanna ecological zones of the country.

A survey was conducted in February of 2004 on the outbreak of stem rot and wilt disease of pepper at the Kitabawa/Danzakara and Ajiwa irrigation sites in Northern Nigeria. Laboratory investigations revealed that it was elicited by Phytophthora capsici Leon. The disease caused severe loss in yield and USD 1 700.00 to USD 3 200.00 loss in revenue/ha. The disease was probably further aggravated by the presence of Fusarium sp. as well as ecto- and endoparasitic nematodes. Reasons for outbreak were elucidated and solutions proffered
