Walnuts (Juglans regia L.) are a major food crop in Beijing. Recently, walnut anthracnose has become serious problem plantations of Beijing, and the diversity pathogens that cause this disease is poorly understood, making targeted treatment difficult. This study investigated incidences seven districts Beijing (Changping, Fangshan, Haidian, Huairou, Mentougou, Miyun Pinggu). A total 377 isolates...

VARIABILITY IN THE PRODUCTION OF FUNGAL SPORES AND IN THE MEASUREMENT OF SPORE YIELDS WAS INVESTIGATED IN FOUR SPECIES OF FUNGI: Colletotrichum gloeosporioides, Colletotrichum coccodes, Colletotrichum phomoides, and Acremonium strictum. When the fungi were grown on solid medium in microplates and spore yields were measured by counting the subsamples with a hemacytometer, the variability among h...

Phenolic compounds are secondary metabolites produced by plants, and their study has been increased in recent years due to ability improve human health. The aim of this work was the determination phenolic presents blue corn flour before after a fermentation process, where different proportions were used (Zea mays L.) Czapek Dox culture medium (90 mL with 10 g flour, 80 20 70 30 flour) fermented...

Abstract The antifungal activity of Trichoderma hamatum K01 to control Colletotrichum gloeosporioides C01 was recorded. Pathogenicity C. on citrus leaves confirmed by the Koch postulate. T. inhibited colony growth and conidia production 70.55 79.07%, respectively. Crude extracts from expressed an against C01. crude TK01-MeOH showed most potent inhibitory effect at ED 50 values 273 355 ppm, Nano...

Apple fruit rot disease is one of the major apple diseases in Indonesia. It has been caused by several species pathogenic within genus Colletotrichum. This research aims to identify pathogen causing Pujon, East Java. Suspected fungal isolates were identified based on morphological (macroscopic and microscopic) molecular characteristics. Based observation, five as Colletotrichum spp. These have ...

Streptomyces are considered to be one of the actinomycetes genera having potential in production agricultural probiotics because they safe and have strong antagonism many bacterial fungal species that cause plant diseases. In this study, 18 strains were isolated from growing oranges’ soil Ha Giang province, which actinomycete strain XK1 was strongly resistant fungi Penicillium digitatum Colleto...

Penyakit antraknosa merupakan penyakit utama dalam budidaya pepaya yang disebabkan oleh Colletotrichum gloeosporioides. Daun kersen dapat menghambat pertumbuhan jamur C. gloeosporioides karena mengandung kelompok senyawa flavonoid, tanin, saponin, dan alkoloid. Penelitian ini bertujuan untuk mengetahui konsentrasi ekstrak kematangan daun paling efektif menekan baik in vitro maupun vivo. Rancang...

The present study investigated the suppression of the disease development of anthracnose caused by Colletotrichum gloeosporioides and C. acutatum in harvested apples using an antagonistic rhizobacterium Paenibacillus polymyxa APEC128 (APEC128). Out of 30 bacterial isolates from apple rhizosphere screened for antagonistic activity, the most effective strain was APEC128 as inferred from the size ...

To develop a quantitative assay of fungal growth inside plant tissues, strains of Colletotrichum destructivum and Colletotrichum orbiculare were transformed with a modified green fluorescent protein (GFP) gene fused with a glyceraldehyde-3-phosphate dehydrogenase promoter from Aspergillus nidulans. Transformants expressed GFP in culture and had the same growth rate and general appearance as the...

Industrial processing of pecan nuts results in edible oil – with fractions fatty acids, polyphenols and phytosterols - that may be used for managing phytopathogens. Besides, chitosan interfere pathogen development directly and/or activate mechanisms defense plant tissues. This study aimed at developing a novel, natural eco-friendly fungicide based on nut immobilized evaluating its activity agai...
