Fusarium wilt (also known as Panama disease) is one of the most destructive banana diseases, and greatly hampers the global production of bananas. Consequently, it has been very detrimental to the Chinese banana industry. An infected plant is one of the major causes of the spread of Fusarium wilt to nearby regions. It is essential to develop an efficient and environmentally sustainable disease ...
در این تحقیق، کارآیی سه گونهی spp. Trichoderma و دو استرین باکتری Bacillus spp. در کنترل بیولوژیک Fusarium oxysporum f. sp. melonis عامل پژمردگی فوزاریومی خربزه در شرایط آزمایشگاه و گلخانه مورد ارزیابی قرارگرفت. آزمونها در قالب طرح کاملاً تصادفی در 4 تکرار انجام شد و برای مقایسهی میانگینها از آزمون LSD در سطح احتمال یک درصد استفاده شد. نتایج بررسیهای آزمایشگاهی روی کارآیی عوامل قارچی کنترل...
In this study, the biocontrol abilities of water-soluble and volatile metabolites of three different isolates of Trichoderma (T. asperellum, T. harzianum and Trichoderma spp.) against soil borne plant pathogen Rhizoctonia solani were investigated both in vitro and in vivo. The results showed for the first time that mycelial growth inhibition of the pathogen was 74.4-67.8% with water-soluble met...
Peanut haulms compost as a carrier of three Trichoderma species (T. harzianum, T. hamatum and T. koningii) exhibited different morphological and chemical characteristics and its ability to control Fusarium wilt of cumin plants caused by Fusarium oxysporum compared with peat/vermiculite. The peanut haulms carrier was able to increase the population size, numbers, viability, survival, microbial b...
Si ngh A, Islam MN (2010) In vitro evaluation of Trichoderma spp against Phytophthora nicotianae. Int. J. Expt. Agric. 1(1), 20-25. The Blank sank disease of tobacco caused by Phytophthora nicotianae results in considerable loss of the crop. This lab study aimed to investigate antagonistic activity of Trichoderma spp isolates against P. nicotianae. Three isolates of Trichoderma harzianum and on...
Trichoderma theobromicola and T. paucisporum spp. nov. are described. Trichoderma theobromicola was isolated as an endophyte from the trunk of a healthy cacao tree (Theobroma cacao, Malvaceae) in Amazonian Peru; it sporulates profusely on common mycological media. Trichoderma paucisporum is represented by two cultures that were obtained in Ecuador from cacao pods partially infected with frosty ...
This work presents results on the effect of manganese ions on the development and biological activities of the fungal antagonists Trichoderma harzianum, Trichoderma pseudokoningii and Trichoderma viride. The effects of manganese on linear growth of Trichoderma spp. depend on the metal concentration and the fungal species. T. harzianum proved the most sensitive fungus. on the other hand, none of...
Trichoderma spp is the cause of the green mold disease in mushroom cultivation production. Many disinfection treatments are commonly applied to lignocellulose substrates to prevent contamination. Mushroom growers are usually worried about the contaminations that may occur after these treatments during handling or spawning. The aim of this paper is to estimate the growth of the green mold Tricho...
The understanding of the dynamic of soil-borne diseases is related to the microbial composition of the rhizosphere which is the key to progress in the field of biological control. Trichoderma spp. is commonly used as a biological control agent. The use of next generation sequencing approaches and quantitative PCR are two successful approaches to assess the effect of using compost as substrate f...
