Infection with Pantoea stewartii subspecies stewartii, which causes jackfruit-bronzing disease, is a huge problem faced by the jackfruit industry in Malaysia. This study was carried out to assess disease ratings and aggressiveness performance of 28 isolated from diseased jackfruits four collection areas (Jenderam Selangor State, Maran Muadzam Shah Pahang Ipoh Perak State) Peninsular Malaysia, i...

fungal diseases, chocolate spot (botrytis fabae sard) is the most destructive diseases of faba bean and causes considerable dramatic damage losses on faba bean yield worldwide. the levels of resistance to chocolate spot were evaluated in 35 faba bean cultivars and one susceptible check (ilb365) and local check (barkat) at the gorgan agricultural research station during the 2010 and 2011 croppin...

Galia muskmelon (Cucumis melo L. var. Reticulatus Ser.) is an F1 hybrid known for exceptional fruit flavor. Since introduction to the market in 1973, the original ‘Galia’ has become a trade name for look-alike cultivars. Some ‘Galia’-type cultivars are firmer, ship well, and may be less susceptible to powdery mildew [Podosphaera xanthii (Px) (syn. Sphaerotheca fulignea)] than a true ‘Galia’, bu...

Aflatoxin contamination is a major economic and food safety concern for the peanut industry that largely could be mitigated by genetic resistance. To screen peanut for aflatoxin resistance, ten genotypes were infected with a green fluorescent protein (GFP)-expressing Aspergillus flavus strain. Percentages of fungal infected area and fungal GFP signal intensity were documented by visual ratings ...

Growth chamber experiments were conducted to examine environmental parameters affecting disease development by the indigenous pathogen Bipolaris sacchari isolate LJB-1L on the invasive weed Lygodium microphyllum (Old World climbing fern). An initial experiment examined three different temperature regimes (20/15, 25/20, 30/25 C; light/dark cycle) and three different periods of leaf wetness (12, ...

Soybean germplasm exhibits various levels of resistance to Fusarium tucumaniae, the main causal agent of sudden death syndrome (SDS) of soybean in Argentina. In this study, two soybean genotypes, one susceptible (NA 4613) and one partially resistant (DM 4670) to SDS infection, were inoculated with F. tucumaniae. Disease symptoms were scored at 7, 10, 14, and 25 days post-inoculation (dpi). The ...
