A total of 33 isolates of Fusarium sp. were isolated from soil samples collected from a mangrove forest in an area in Kampung Pantai Acheh, Balik Pulau, Pulau Pinang, Malaysia. The isolates were isolated using soil dilution, direct isolation and debris isolation techniques. The debris isolation technique yielded the most isolates, with a total of 22 Fusarium isolates. Based on identification us...
Fusarium wilts of strawberry, caused by Fusarium oxysporum f. sp. fragariae, is a serious soil-borne disease. Fusarium wilt causes dramatic yield losses in commercial strawberry production and it is a very stubborn disease to control. Reliable chemical control of strawberry Fusarium wilt disease is not yet available. Moreover, other well-known F. oxysporum have different genetic information fro...
Bacillus amyloliquefaciens NJN-6 produces volatile compounds (VOCs) that inhibit the growth and spore germination of Fusarium oxysporum f. sp. cubense. Among the total of 36 volatile compounds detected, 11 compounds completely inhibited fungal growth. The antifungal activity of these compounds suggested that VOCs can play important roles over short and long distances in the suppression of Fusar...
در این تحقیق اثر کاربرد سیلیکون و باکتری (pseudomonas fluorescens (chao روی بیماری پژمردگی فوزاریومی گوجه فرنگی ناشی از قارچ fusarium oxysporum f. sp. lycopersiciو القای مقاومت میزبان در مقابل پاتوژن مورد بررسی قرار گرفت. اثر غلظتهای مختلف سیلیکون ( 7-1 میلی مولار) بر رشد pseudomonas fluorescens و fusarium oxysporum f. sp. lycopersici آزمایش شد. نتایج نشان داد که همه غلظتهای سیلیکون روی رشد ب...
Preventive measures against soil-borne diseases need to be implemented before cultivation because very few countermeasures are available after the development of diseases. Some soils suppress soil-borne diseases despite the presence of a high population density of pathogens. If the suppressiveness of soil against soil-borne diseases may be predicted and diagnosed for crop fields, it may be poss...
Guava (Psidium guajava L.) is an important fruit crop of subtropical countries and cultivated extensively throughout India, it is grown almost in all the states. Bihar has the largest area (24.7 thousand ha.) under guava cultivation followed by Uttar Pradesh (18.5 thousand ha.) and Maharastra (14.8 thousand ha.). Various pathogens have been reported from the wilt affected plants from guava orch...
دستیابی به اطلاعات مولکولی و ژنتیکی توانسته است بسیاری از چالش های علوم زیستی را در جنبه های مختلف حل کند. روش های کاربردی بسیاری جهت استخراج dna از بافت های جانوری و گیاهی و سایر موجودات زنده شناسایی و معرفی شده است.، در بسیاری مطالعات ژنتیکی در جوامع میکروبی، اغلب نیاز به استخراج مستقیم dna از خاک است. در این تحقیق پس از مطالعه دقیق روش های مختلف پیشنهادی، سه روش (شیمیایی- آنزیمی)، (شیمیایی- ...
The antifungal compound 2,4-diacetylphloroglucinol-producing bacterium, Pseudomonas fluorescens strain LRB3W1, inhibits the growth of Fusarium oxysporum f. sp. lycopersici, and controls Fusarium wilt of tomato caused by F. oxysporum f. sp. lycopersici. On the other hand, Serratia marcescens strain B2, which produces cell wall-degrading enzyme chitinases, did not inhibit fungal growth and the su...
Rosmarinus officinalis is a well-studied species; however, R. essential oil (EO) from West highlands of Algeria was not investigated chemically and biologically. In this context, chemical composition EOs obtained leaves stem were determined by GC/MS analysis their antifungal activity against Fusarium oxysporum f. sp. albedinis (Foa) evaluated. The indicated that monoterpenes the dominant class ...
Plant extracts and essential oils are promising new sources of non-toxic alternatives to chemicals substances. They used for their antimicrobial properties against plant diseases fungal origin, bacterial, those virus origin. This study was carried out the antifungal activity Artemisia herba-alba, Foeniculum vulgare Citrus sinensis Fusarium oxysporum f. sp. albedinis. Essential oil extracted by ...
