Seventy-two sorghum accessions were randomly selected from the Ethiopia, Mali, Sudan, and Uganda germplasm collections maintained by the US National Plant Germplasm System to evaluate variation in anthracnose resistance. The accessions were planted in a randomized complete block design in College Station, Texas during the 2007 and 2008 growing seasons. Twenty-six accessions exhibited a resistan...

For at least the past decade, an unusual decline of black walnut (Juglans nigra) has been observed in several western states. Initial symptoms involve a yellowing and thinning of the upper crown, which progresses to include death of progressively larger branches (Figure 1). During the final stages large areas of foliage may rapidly wilt. Trees often are killed within three years after initial s...

AIM Identification of cyclopropyl fatty acids in walnut oil. METHOD GC/MS method was developed for the determination of eight cyclopropyl fatty acids in walnut (Juglans regia) oil. RESULTS Monocyclopropane acids: methyl 9-cyclopropyl-nonanoate, 6,7-methylene-, 8,9-methylene-, 9,10-methylene-, 11,12-methylene octadecanoates, and dicyclic acid - methyl 9,10,12,13-dimethylene octadecanoate, tr...

In March 2011, anthracnose symptoms were observed on stems of Dracaena sanderiana as imported ornamental plant in Gorgan, Golestan province (NE Iran). According to the Farr et al. (2006) the pathogenic fungus were identified as Colletotrichum dracaenophilum D.F. Farr & M.E. Palm. 

oxidative stability of walnut (juglansregia l.) was evaluated over a period of 1 year storage in various conditions. the whole walnuts, walnut kernels, walnut chopped kernels, walnut kernels packaged in polyethylene (pet) under vacuum and poly propylene (pp) contain of co2 were kept in a normal condition (temperature, 19-30˚с and relative humidity (rh), 35-45%). the whole walnuts and walnut ker...

Wound anthracnose is a post-harvest disease which develops during storage and ripening of bananas. In the French West Indies, it mainly occurs on fruits coming from plantations situated on soils at low-altitude, during the second half of the year. It is caused by a pathogenic fungus, Colletotrichum musae. A diagnostic survey was carried out on 106 plots representative of all the soil/climatic c...

Muscadine grapes (Vitis rotundifolia Michx) are considered as excellent genetic resources for grape breeding programs as they are known for their hardiness and resistance to pests and diseases. However, contrary to popular belief, our study indicated that not all muscadine cultivars are resistant to anthracnose disease. In order to identify a source of genetic tolerance towards anthracnose amon...

Anthracnose development by Colletotrichum musae was observed to be significantly less in the fruits of the banana cultivar 'Embul' (Mysore, AAB) infected with Phyllosticta musarum than in fruits without such infections. Anthracnose disease originates from quiescent C. musae infections in the immature fruit. P. musarum incites minute, scattered spots, referred to as freckles, in the superficial ...
