What is Colletotrichum spp?

What is Colletotrichum spp?

Colletotrichum (sexual stage: Glomerella) is a genus of fungi that are symbionts to plants as endophytes (living within the plant) or phytopathogens. Many of the species in this genus are plant pathogens, but some species may have a mutualistic relationship with hosts.

Which of the following is the characteristic of Colletotrichum?

Identification and characterization of Colletotrichum species is based on morphological characters such as size and shape of conidia and appressoria, existence of setae or presence of a teleomorph, and cultural characters such as colony color, growth rate and texture (Smith and Black, 1990).

How does Colletotrichum spread?

Infection is primarily seed-borne, but infected plants rapidly produce secondary inoculum, which can be spread through a crop by wind and rain splash.

What is Colletotrichum Falcatum?

Colletotrichum falcatum, a concealed fungal ascomycete causes red rot, which is a serious disease in sugarcane. It infects economically important stalk tissues, considered as store house of sugar in sugarcane.

How do you identify Colletotrichum?

Colletotrichum truncatum was the most commonly isolated species from infected chili fruit and was readily identified by its falcate spores and abundant setae in the necrotic lesions.

Which disease is caused by Colletotrichum?

Chilli anthracnose disease caused by Colletotrichum species.

Is trade name of colletotrichum Gloeosporioides?

Glomerella cingulata is a fungal plant pathogen, being the name of the sexual stage (teleomorph) while the more commonly referred to asexual stage (anamorph) is called Colletotrichum gloeosporioides.

What is the perfect stage of Colletotrichum?

The perithecial stage was developed in the laboratory on sterilized cane, sorghum, and cane leaves and strips of filter paper inoculated with a culture of C. falcatum under humid conditions. P. tucumanensis was shown to be homothallic, perithecia being readily produced from single ascospore cultures.

What is Favourable condition of rice blast organism?

Conditions conducive for rice blast include long periods of free moisture and/or high humidity, because leaf wetness is required for infection. Sporulation increases with high relative humidity and at 77–82 °F (25–28 °C), spore germination, lesion formation, and sporulation are at optimum levels.

What is the anthracnose disease?

Anthracnose is a fungal disease that tends to attack plants in the spring when the weather is cool and wet, primarily on leaves and twigs. The fungi overwinter in dead twigs and fallen leaves. Cool, rainy weather creates perfect conditions for the spores to spread.
