To improve the integrated pest management (IPM) of hot pepper, field study was conducted in Hwasung from 2010 to 2012 and an IPM system was developed to help growers decide when to apply pesticides to control anthracnose, tobacco budworm, Phytophthora blight, bacterial wilt, and bacterial leaf spot. The three field treatments consisted of IPM sprays following the forecast model advisory, a peri...

Anthracnose is among the most economically important diseases affecting pepper (Capsicum spp.) production in the tropics and subtropics. Of the three species of Colletotrichum implicated as causal agents of pepper anthracnose, C. truncatum is considered to be the most destructive in agro-ecosystems worldwide. However, the genetic variation and the migration potential of C. truncatum infecting p...

Anthracnose, caused by Colletotrichum lindemuthianum, is an important fungal disease of common bean (Phaseolus vulgaris). Alleles at the Co-4 locus confer resistance to a number of races of C. lindemuthianum. A population of 94 F4:5 recombinant inbred lines of a cross between resistant black bean genotype B09197 and susceptible navy bean cultivar Nautica was used to identify markers associated ...

Colletotrichum higginsianum is an economically important pathogen that causes anthracnose disease in a wide range of cruciferous crops. To facilitate the efficient control of anthracnose disease, it will be important to understand the mechanism by which the cruciferous crops and C. higginsianum interact. A key step in understanding this interaction is characterizing the mitogen-activated protei...

In filamentous fungi, Sfp-type 4'-phosphopantetheinyl transferases (PPTases) activate enzymes involved in primary (alpha-aminoadipate reductase [AAR]) and secondary (polyketide synthases and nonribosomal peptide synthetases) metabolism. We cloned the PPTase gene PPT1 of the maize anthracnose fungus Colletotrichum graminicola and generated PPTase-deficient mutants (Deltappt1). Deltappt1 strains ...

Olive anthracnose, caused by Colletotrichum, is an important disease in olive-growing regions, with the most destructive symptoms being fruit rot and blossom blight. Susceptibility of to Colletotrichum increases maturity, but differences between cultivars species have been reported, still information on flower susceptibility during development scarce. The olive Arbequina, Coratina, Frantoio Pic...

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...

Colletotrichum karstii is reported, for the first time, causing anthracnose on native Brazilian orchid Cattleya walkeriana. Identification was confirmed through a combination of morphological and molecular (phylogenetic analysis ITS, GAPDH TUB2 regions) data. Koch’s postulates were fulfilled inoculation C.
