This study examines the most effective anti-Botrytis strategies leading to possible lower pesticides residues in wine. To provide wine growers with a number of high-quality solutions for protection against Botrytis for their vineyards while minimizing pesticide residues in the final product, various treatment approaches were tested. A total of 10 strategies with different specific fungicide tre...
Botrytis cinerea is a major plant pathogen, causing gray mold rot in a variety of cultures. Repeated fungicide applications are common but have resulted in the development of fungal populations with resistance to one or more fungicides. In this study, we have monitored fungicide resistance frequencies and the occurrence of multiple resistance in Botrytis isolates from raspberries, strawberries,...
Botrytis cinerea is a plant-pathogenic fungus infecting over 200 different plant species. We use a molecular genetic approach to study the process of pectin degradation by the fungus. Recently, we described the cloning and characterization of an endopolygalacturonase (endoPG) gene from B. cinerea (Bcpg1) which is required for full virulence. Here we describe the cloning and characterization of ...

Research was carried out to evaluate the effectiveness of the biological control of the Botrytis gray mould, caused by Botrytis cinerea Pers., one of the most important fungal diseases of the tomato (Lycopersicon esculentum Mill.). Biological control was performed by using Trichoderma harzianum Rifai, an antagonist that is a naturally occurring fungus found on some plants and in the soil worldw...
Natural geranyl compounds are known to exhibit important biological activities. In this work a series of geranylphenols were synthesized to evaluate their effect on the mycelial growth of Botrytis cinerea. Geranyl derivatives were synthesized by direct geranylation reactions between the corresponding phenol derivatives and geraniol, using BF3.OEt2 as catalyst and AgNO3 as secondary catalyst. Pr...
این تحقیق به منظور بررسی تاثیر کار برد منابع نیترات و سولفات کلسیم بر خصوصیات فیزیولوژیکی و مرفولوژیکی در دو رقم از گل سوسن در طول دو سال و در سه فصل متفاوت در دانشکده علوم کشاورزی دانشگاه گیلان انجام گردید. آزمایش اول به صورت فاکتوریل در قالب طرح کاملا تصادفی در سه تکرار بر رقم های سوسن به نام های ناونا [navona] و فانجیو [fangio] با سطوح مختلف اسید ایندول بوتریک [iba] در غلظت های 500، 750 و 10...
This study demonstrates that the isoprenoid farnesol produces a toxic effect on the phytopathogenic fungus Botrytis cinerea in solid and liquid media. In solid media farnesol retarded 72 h the beginning of mycelial growth. Also, it was demonstrated that the toxic effect is due to farnesol triggers apoptosis in B. cinerea because ROS accumulation, DNA fragmentation and phosphatidylserine externa...
Necrotrophic fungi are unable to occupy living plant cells. How such pathogens survive first contact with living host tissue and initiate infection is therefore unclear. Here, we show that the necrotrophic grey mold fungus Botrytis cinerea undergoes massive apoptotic-like programmed cell death (PCD) following germination on the host plant. Manipulation of an anti-apoptotic gene BcBIR1 modified ...
A series of linear furanocoumarins with different substituents have been designed and synthesized. Their structures were confirmed by ¹H-NMR spectroscopy, high resolution mass spectra (EI-MS), IR, and X-ray single-crystal diffraction. All of the target compounds were evaluated in vitro for their antifungal activity against Rhizoctorzia solani, Botrytis cinerea, Alternaria solani, Gibberella zea...
