Biology and Control of Pepper Anthracnose
Anthracnose (caused by Colletotrichum capsici or C. gloeosporioides) of bell peppers (Capsicum annum) has become a serious problem in recent years on the Eastern Shore of Virginia. The purpose of this research was to characterize isolates of the fungus from the Eastern United States, to compare …

Resistance to anthracnose leaf blight in sorghum
… which lower the production of sorghum. Sorghum anthracnose may cause from 50 to 86% yield losses and is caused by a hemi-biotrophic fungal pathogen Colletotrichum sublineola. The pathogen is host specific and survives on seeds, mycelium, conidia, and soil. There are three forms of the disease: …

Abiotic stressors in the dogwood anthracnose complex
… reportedly enhances disease severity of dogwood anthracnose (DA) caused by Discula destructiva, on Cornus florida, the flowering dogwood. Seedlings were subjected to acidic fog episodes at pHs 2.5, 3.5, 4.5, and 5.5, using a simulated acidic rain solution. Leaf discs from these and non-treated …

Anthracnose on almond: epidemiology and characterisation of Colletotrichum acutatum.
In Australia, anthracnose on almond is caused by the ascomycete fungus Colletotrichum acutatum. Anthracnose has been confirmed throughout the major almond growing regions of Australia and significant economic losses have been reported. Fungicide trials carried out in Australia in 2000, prior to …

Yield Loss Studies With Anthracnose Stalk Rot of Corn
Twenty-four dent corn hybrids were inoculated in the first elongated stalk internode by injecting a spore suspension of Colletotrichum graminicola or Diplodia maydis to estimate potential yield loss. Experiments were done from 1978-1980 with a second location and D. maydis inoculations added in …

Inheritance of resistance to anthracnose stalk rot of corn
Inheritance of resistance to anthracnose stalk rot (ASR) of corn (Zea mays L.), caused by Colletotrichum graminicola was studied in eight crosses involving two resistant inbred lines DW1035 ((MP305 x FRB73$\sp{\lbrack 5\rbrack }$)$\sb{\rm S8}$) and DW890 ((MP305 x FRB73$\sp{\lbrack 5\rbrack …

Sources and Inheritance of Resistance to Anthracnose Stalk Rot of Corn
… corn (Zea mays) in the Midwest. In recent years anthracnose leaf blight and stalk rot, caused by Colletotrichum graminicola, have increased in prevalane in the warmer, humid corn-growing regions of the U.S. Recent evidence shows a great potential for anthracnose stalk rot to cause yield losses. …

Resistance to Walnut Anthracnose Development in Juvenile Leaves of Black Walnut Seedlings
Walnut anthracnose is the most serious foliar disease of black walnut causing premature defoliation and reduced growth. Early studies failed to identify functionally resistant cultivars of balck walnut to this disease. From previous artificial inoculation studies on greenhouse-grown seedlings, …

Molecular phylogeny of Melanospora and Diaporthales, and population genetics of dogwood anthracnose fungus
Unresolved phylogenetic problems in pyrenomycetes and population structure of an asexual plant pathogen (Discula destructiva) were investigated. Analyses based on DNA sequences of nuclear encoded small and large subunit RNA genes (SSU and LSU nrDNA) and deduced amino acid sequences of a subunit of …

Biology of Soybean Anthracnose Fungi and Their Interaction With Other Soybean Fungi (Colletotrichum, Synanamorph, Biocontrol)
… evident only with C. truncatum causing foliar anthracnose. Anthracnose severity was increased with increased incubation period in a mist chamber causing death of V-1 soybeans in 72 hr. Plants at V-2 to R-4 stages were all defoliated and showed stem-tip blights, but were not killed. Plants under …

Control of anthracnose (caused by Colletotrichum gloeosporioides s.l.) on mango in Senegal by fungicides and biofungicides
… been considered the causal pathogen of anthracnose of mango and other fruits, but is now known to represent a species complex. Field trials to examine the efficacy of fungicides and biofungicides were conducted in southern and northern production regions of Senegal. In three southern …

Evaluation for drought tolerance and anthracnose resistance of selected pinto genotypes of common bean (phaseolus vulgaris l.).
… that the country is prone to drought and anthracnose disease. Anthracnose is the most important disease of common bean in Zambia, which is likely to affect production of this market class in a similar way it has affected other currently grown market classes. Additionally, drought has …

Studies in the physiology, genetics and pathology of Colletotrichum phomoides (Sacc.) Chester, the cause of tomato anthracnose
Anthracnose of tomato was first described by Chester in 1891. It has been of economic importance to the growers of canning tomatoes nearly ever since. Anthracnose is cause by Colletptrochum phomoides (sacc.) Chester which appears to have different physiologic and morphologic forms. There is …

Morphological and molecular identification, pathogenicity characterization of colletotrichum species on soybean, and the resistance of soybean genotypes
… Colletotrichum species often are referred to as anthracnose. The species associated with soybean [Glycine max (L.) Merr.] have not been sufficiently studied in terms of their genotype discrimination and phylogenetic relationships. Moreover, there is little information on evaluation of soybean …

Determination of the variability of colletotrichum Truncatum, the causal agent of Anthracnose of Soyabean (Glycine max( L) Merr.) in Zambia
… hampered by several foliar diseases of which the anthracnose caused by Collectotrichum truncatum appear to be the most prevalent, than red leaf blotch cause by Dactuliochaeta glycines reported before. A study on anthracnose of soyabean disease was undertaken to determine the level of variability …

Host Plant Resistance in Strawberries to Anthracnose and Colonization of Crown and Root Tissue by Verticillium dahliae and Macrophomina phaseolina
… in order to evaluate host resistance of anthracnose in 105 cultivars and elite breeding lines developed by six strawberry breeding programs. Cultivars and elite breeding lines were inoculated using three local isolates in both years. All breeding programs provided genotypes that had a …
