in order to investigate the effects of cattle manure, benefit fungi of trichoderma species and psudomunas spp. bacteria on seedling emergence parameters, growth and yield of wheat (triticum aestivum l.) a pot experiment was carried out in factorial (23) arrangement based on a randomized complete design with three replications. the treatments were three levels of cattle manure (10, 20 and 30 t.h...

One of the main obstacles to feeding world is fungal leaf spot disease, which has a negative impact on plants' photosynthetic areas and significantly lowers crop quality output. To manage fungi that pose serious hazard both humans environment, various chemical fungicides are utilized. The goal current study was determine whether local isolates three Trichoderma spp. (Trichoderma viride, harzian...

AIM The main goal of the present research conducted to assess the in vitro activity of the nematophagous fungi Duddingtonia flagrans, Fusarium solani, Verticillium chlamidosporium, and Trichoderma harzianum. MATERIAL AND METHODS Four isolates of fungi including D. flagrans, F. solani, V. chlamidosporium and T. harzianum were used in this study. Horse faeces were used to provide the larvae sta...

Macrophomina phaseolina (Tassi) Goid is a destructive pathogen of cowpea that causes serious charcoal rot disease with significant yield losses. Antifungal activity of three indigenous Ascomycetes viz., Trichoderma harzianum, T. viride, and T. hamatum, and two Meliaceae members, i.e., Melia azedarach L. and Azadirachta indica L. were assessed against the pathogen. Laboratory screening trials wi...

Fusarium graminearum Schwabe causes Fusarium head blight (FHB), a devastating disease that leads to extensive yield and quality loss of wheat and other cereal crops. Twelve isolates of F. graminearum were collected from naturally infected spikes of wheat from Assiut Egypt. These isolates were compared using SRAP. The results indicated distinct genetic groups exist within F. graminearum, and dem...

trichoderma harzianum (t39), t.virens (dar74290), t.viride (mo), t. harzianum (m) and trichderminb a commercial formulation of t. harzianum(bi) were evaluated as potential biological agents for the control of charcoal stem rot in melon caused by macrophomina phaseolina. cell-free metabolites of t. harzianum(m), t. harzianum (t39) and t. virens (dar 74290) inhibited growth of m. phaseolina compl...

Pine sawdust (9 kg m−2) was ploughed into soils, intended for future forestry plantations, that had been left for 3 or 6 years after previously being used for agriculture. Two years after the amendment, soil pH had changed in both sites and the C:N ratio had increased. Total fungal populations decreased after the treatment. A small decrease in the number of species was not statistically signifi...

Fusarium head blight (FHB) is an important disease of wheat and causes significant economic and yield losses. The principal pathogen associated with FHB in Manitoba is Gibberella zeae (Schwein.) Petch (anamorph = Fusarium graminearum Schwabe). Trichoderma harzianum Rifai is a well-known biocontrol agent of many plant pathogens. The extracts from 11 T. harzianum isolates and cellfree filtrates w...

Because of its elevated cellulolytic activity, the filamentous fungus Trichoderma harzianum has a considerable potential in biomass hydrolysis applications. Trichoderma harzianum cellobiohydrolase I (ThCBHI), an exoglucanase, is an important enzyme in the process of cellulose degradation. Here, we report an easy single-step ion-exchange chromatographic method for purification of ThCBHI and its ...

Trichoderma spp. are important biocontrol filamentous fungi, which are widely used for their adaptability, broad antimicrobial spectrum, and various antagonistic mechanisms. In our previous studies, we cloned thga1 gene encoding GαI protein from Trichoderma harzianum Th-33. Its knockout mutant showed that the growth rate, conidial yield, cAMP level, antagonistic action, and hydrophobicity decre...
