the common hazel (corylus avellana) is a species native to the northwest of iran, with over 12500 ha grown in the province of guilan. in the autumn of 2011, twigs and branch galls of corylus avellana were frequently observed on common hazel trees in eshkevarat orchards in the province of guilan. on hazel trees the galls appear as large nodules initiated on twigs in which tissues developed more ...

In the present study, 217 rhizobacterial isolates were obtained from six different tea estates of Assam, India and subjected to preliminary in vitro plant growth promotion (PGP) screening for indole acetic acid (IAA) production, phosphate solubilization, siderophore production and ammonia production. Fifty isolates showed all the PGP traits and five isolates did not exhibit any PGP traits. Thes...

BACKGROUND Ancylostoma species have demanded attention due to their zoonotic potential. The use of anthelmintics is the usual method to prevent environmental contamination by Ancylostoma eggs and larvae. Nematophagous fungi have been widely used in their biological control due to the fungus ability to capture and digest free nematode forms. AIMS The aim of this study was to evaluate the effec...

Twenty-eight potential biocontrol organisms were tested for efficacy against Rhizoctonia solani on potato in a series of greenhouse trials. Organisms tested consisted of field isolates of Paenibacillus polymyxa, Pseudomonas fluorescens, Penicillium sp., Trichoderma sp., and Rhizoctonia zeae; known biocontrol isolates including Laetisaria arvalis, Verticillium biguttatum, Cladorrhinum foecundiss...

The most common biological control agents (BCAs) of the genus Trichoderma have been reported to be strains of Trichoderma virens, T. harzianum, and T. viride. Since Trichoderma BCAs use different mechanisms of biocontrol, it is very important to explore the synergistic effects expressed by different genotypes for their practical use in agriculture. Characterization of 16 biocontrol strains, pre...

Abstract Background Plant disease administration is difficult due to the soil-borne nature of phytopathogens. Biological control plant a safe mode avoid problems related fungal diseases that affect crops productivity. Results Twenty-three Trichoderma isolates were isolated from soil, surrounding healthy tomato roots different regions in Egyptian Governorate Menoufia. Using dual culture method t...

Banded leaf and sheath blight (BLSB) of maize (Zea mays L.) caused by Rhizoctonia solani f. sp. sasakii is one the most important yield-limiting factors faced growers in India. Therefore, attempts were made to identify promising suitable bioagents for management BLSB maize. Present study was carried out check efficacy two bioformulations, viz. Pusa Th3 (Trichoderma harzianum) Cg2 (Chaetomium gl...
