What does Colletotrichum cause?
In India, Colletotrichum causes three types of foliar symptoms, namely leaf blight, shot hole, and irregular leaf spot. Of these, leaf blight and shot hole are widespread and occur on plants of all age groups. Shade regulation is found to be an effective method of control of the disease in Ghana.
How do you treat Colletotrichum Gloeosporioides?
Treat the seed in hot water if using own seed. Improve air circulation by providing adequate spacing during planting. Plant more resistant varieties, as level of resistance (polygenic) against Colletotrichum spp. exists in many crop varieties.
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.
What class is Colletotrichum?
Sordariomycetes
Colletotrichum/Class
Does Colletotrichum have a perfect stage?
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.
Is Colletotrichum Septate?
Colonies 75–80 mm diameter at 25 °C and 11 mm diameter at 37 °C in 7 days. Vegetative hyphae hyaline to medium brown, usually smooth-walled, septate, branched.
How is Colletotrichum spread?
Dispersal is primarily via asexual spores (conidia) produced by Colletotrichum. The pathogen can also be spread through infected plant material, including seed produced in infected pods.
How do you control colletotrichum?
The best control products were Daconil Ultrex (chlorothalonil), Pageant (pyraclostrobin and boscalid) and Spectro 90WDG (chlorothalonil and thiophanate methyl). In addition, mancozeb (i.e., Dithane and Pentathlon) or copper (Phyton 27) were also very effective when used preventively.
What causes citrus scab?
Scab is a serious disease of all lemon varieties on the coast. The disease also affects Rangpur lime, and rough lemon rootstocks. Scab is caused by the fungus Elsinoe fawcettii. Citrus scab attacks the fruit, leaves and twigs, producing slightly raised, irregular scabby or wart- like outgrowths.
What is anthracnose of mango?
Mango anthracnose is caused by the fungus Colletotrichum gloeosporioides var minor (also known by the name of its perfect stage Glomerella cingulata var minor). Spore production by this fungus is favoured by wet or humid weather. The dispersal of these spores is particularly favoured by rain and wind.
