The infection process of Erysiphe pisi on field pea cvs. ‘Highlight’ and ‘Tara’ carrying resistance gene erl, line ‘JI2480’ carrying resistance gene er2, and susceptible cv. ‘Radley’ (Er) was studied at 20 °C in controlled conditions. The growth stages of E. pisi were observed on these cultivars ...

Der Infektionsprozess von Erysiphe pisi an den Felderbsensorten ‘Highlight’ und ‘Tara’, die das Resistenzgen er1 tragen, an der Linie ‘JI2480’ mit dem Resistenzgen er2 sowie an der anfälligen Sorte ‘Radley’ (Er) wurde bei 20 °C unter kontrollierten Bedingungen untersucht.

Aphids are regarded as important pest problems of vegetable crops worldwide. Most vegetable growers in sub-Saharan Africa heavily rely on synthetic chemical insecticides for aphids’ control. Fungus-based biopesticides are being considered as alternatives to chemical insecticides. This study evalu...

Bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) leads to a substantial yield reduction of up to 50% in most rice-growing regions. Host plant resistance is an effective control method, and more than 30 resistance genes have been identified in rice genotypes. To understand the intera...

A collection of 122 isolates of Magnaporthe oryzae, from nine sub-Saharan African countries, was assessed for virulence diversity and genetic relatedness. The virulence spectrum was assessed by pathotype analysis with a panel of 43 rice genotypes consisting of differential lines carrying 24 blast...

Striga aspera and S. hermonthica are sympatric in Africa. Each may serve as virulent gene reservoirs for the other if they hybridize and their hybrids are virulent and fertile. Intraspecific and interspecific crosses were made within and between the species, and reproductive success was determine...

Field surveys were conducted in 2012 and 2013 to evaluate the distribution and virulence of fungal isolates associated with tuber rot disease among yam (Dioscorea spp.) producing agroecological zones (AEZs) of Nigeria. A total of 70 and 66 farmers’ fields were surveyed in 2012 and 2013, respectiv...
