Introduction and objectives: Microbiological control agents (MBCA) are widely used in greenhouses, replacing chemical pesticides. The presented study aims to describe health e ects of exposure to three types commonly used: Bacillus thuringiensis, Verticillium lecanii, and Trichoderma harzenianum covering seven di erent products in greenhouse workers with emphasis on sensitization and respirator...
Pathogenicity and virulence of entomogenous fungus, Verticillium lecanii, was studied on the pea aphid, Acyrthosiphon pisum. Vertalec, a commercial product of V. lecanii, was evaluated under controlled conditions. Second instar nymphs were inoculated with conidial suspensions at concentrations ranging from 104 to 108 conidia/ml, and sterile distilled water (containing wetting agent) as control,...
In order to identify some endophytic fungi in common yew trees, healthy plant samples were investigated. In this study, 10 fungal species including Absidia spinosa, Aureobasidium pullulans, Lecanicillium lecanii, Nemania serpens, Pseudodictyosporium elegans, Leucostoma persoonii, Epicoccum nigrum, Stachybotrys chartarum, Gibberella tricincta and Gibberella baccata were identified as endophytic ...
طی بازدیدهایی در سالهای 1386-1384 از باغهای زیتون استان خوزستان، از درختان زیتون با علائم پژمردگی، سرخشکیدگی و در بعضی موارد زوال نمونهبرداری شد. پس از شستشو و ضدعفونی سطحی، نمونهها در محیط pda کشت و در دمای 25 درجه سلسیوس نگهداری شدند.از ریشه و طوقه زیتون 124 جدایه قارچ جداسازی گردیدکه شامل یک گونه از جنس ورتیسیلیوم (v. dahliae با 35 جدایه)، سه گونه از جنس فوزاریوم (f. solani با 23 جدایه،f...
