2012 | الكلمات المفتاحية Fusarium moniliforme, microelements, grain sorghum stalk rot,
Effect of certain microelements on grain sorghum stalk rot caused by Fusarium moniliforme J. Sheld.
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

2011 | الكلمات المفتاحية fumonisins, Fusarium,
Virulence of Fusarium verticilliodes (SACC.) Nirenberg (G) isolates on maize plants associated with fumonisins Production.
_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

2011 | الكلمات المفتاحية wheat, trichothecene, Fusarium graminearum,
Aggressiveness of certain Fusarium graminearum isolates on wheat seedlings and  relation with their trichothecene production
_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

2011 | الكلمات المفتاحية Postharvest, Green Mold of Orange, essential oils,
Efficacy of Some Essential Oils on Controlling Green Mold of Orange and their Effects on Postharvest Quality Parameters
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

2010 | الكلمات المفتاحية resistance inducers, faba bean wilt,
Application of certain resistance inducers for controlling faba bean wilt disease under greenhouse and field conditions
_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

2010 | الكلمات المفتاحية Wilt Disease of Faba Bean, Fusarium oxysporum, Trichoderma spp,
Induction of Defense Responses Against Wilt Disease of Faba Bean (Vicia faba L.) Caused by Fusarium oxysporum f.sp fabae (schlecht) by Biocontrol Agent Trichoderma spp.
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

2009 | الكلمات المفتاحية Antibacterial activity, plant extracts, bacterial wilt of tomato,
Antibacterial activity of certain plant extracts against bacterial wilt of tomato.
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
