Grain sorghum [_Sorghum bicolor_ L. (Moench)] is subjected to infection by certain diseases causing great and substantial damage to the crop. _Fusarium_ stalk rot of sorghum caused by _F_. _moniliforme_ (J. Sheld) represents the common stalk rot in Egypt and many areas of the world. The tested sorghum cultivars reacted differently to _F.__moniliforme_ in the two tested seasons. Giza15 sorghum ... إقراء المزيد

_Fusarium verticilliodes_ (Sacc.) Nirenberg (G) is a well known phytopathogenic fungus capable to infect a wide range of plants including maize. In addition; its toxic metabolites fumonisin (FB1 and FB2) are associated with Equina Leukoencephalo Malacia and induced hepatotoxic and carcinogenic effects in animals. Twenty two isolates of _F. verticilliodes_ obtained from corn samples and grown on Barley medium, were ... إقراء المزيد

_Fusarium_ fungi, including _F. graminearum_, cause seedling blight, foot rot and head blight diseases in wheat resulting in yield loss. Trichothecene mycotoxins are a group of toxic fungal secondary metabolites. This group of toxins is found associated with _Fusarium_ diseases in wheat in numerous countries worldwide. Five isolates of _F. graminearum_ were examined for their degree of disease severity (virulence) ... إقراء المزيد

The effect of lime, thyme, comphore oils against _Penicillium digitatum_, the causes of green mould disease of orange fruits, was evaluated for their inhibitory effect _In vitro_ and _In vivo_ during storage conditions. _In vitro_ experiments, different concentration of each essential oil at 1, 5 and 10% (v/v) was tested on the growth of _P. digitatum_. The best concentration at ... إقراء المزيد

_Fusarium oxysporum_ f.sp. _fabae_ (Schlecht) Snyder &.Hansen (FOF) is a serious pathogen on faba bean causing wilt disease. In greenhouse experiments, the three tested isolates of the pathogen were differed in their virulence on faba bean cultivars (Giza 29, Giza 4 and Misr 1). Isolate (FF1) was the most virulent one. Faba bean cultivars reacted differently to the infection by ... إقراء المزيد

The aim of this study was to evaluate _Trichoderma_ spp for protection of faba bean plants against wilt disease caused by _Fusarium oxysporum_ f.sp _fabae_ (Schlecht) (FO). FO was isolated from diseased faba bean roots collected from different locations of Assiut governorate. The antagonistic capability of _Trichoderma_ spp. isolates against linear growth of FO isolate was tested and all _Trichoderma_ ... إقراء المزيد

Five isolates of _Ralstonia solanacearum_ were isolated from a naturally wilted root of tomato plants grown in Assiut governorate. The antibacterial activity of extract of Datura, Garlic and Nerium were tested in controlling _R. solanacearum__in vitro_ and _in vivo_. Garlic exhibited the strongest antibacterial activity against bacterial wilt _in vitro_ and _in vivo_ followed by Datura and then Nerium. Cold ... إقراء المزيد
