Colletotrichum species

Colletotrichum species cause anthracnose in various tropical crops in both cultivation and postharvest periods. The current synthetic fungicides to treat anthracnose sometime show toxic effects for farmers, residues on foods, and environmental impacts. In this work, turmeric extract containing curcuminoids was used as an active ingredient and formulated into a nanoemulsion to control anthracnose in red pepper and tomato fruits.

In Thailand, there are three major species of Colletotrichum spp. which caused anthracnose disease to chili product; Colletotrichum gloeosporioides, C. capsici and C. acutatum. In 2015, the researchers from Thailand Institute of Nuclear Technology reported a first success of radiation-induced mutation breeding for anthracnose resistance which caused by C. gloeosporioides in Sukhothai.

Colletotrichum species are the causal agents of anthracnose, a major disease affecting the yield and quality of pepper (Capsicum spp.). Colletotrichum scovillei is widespread in China, has strong pathogenicity and drug resistance, and causes anthracnose disease in pepper fruits that severely reduces production.

Anthracnose leaf disease in rubber trees, caused by the attack of Colletotrichum gloeosporioides, have led to the serious decline in natural rubber production. Continuous usage of synthetic fungicide leave the toxic residues that harm the surrounding animals and plants and are not environmentally friendly. It needs a better solution with organic products that are safer, more effective and biodegradable. Piper species could be considered as a source of new natural products with potential antifungal activities.

The objectives of the thesis: Identify the pathogenicity potential and classificate at species level of Colletotrichum spp. isolated from hot chilli in Vietnam; produce stable oligochitosan-silica nano, which potentially highly induced effectively the systemic resistance against anthranose disease on hot chilli, based on the combination of low molecular weight chitosan with nano silica.

Colletotrichum species is responsible for anthracnose, a worldwide serious disease, causing an important loss in chili pepper production. Therefore, screening disease resistant and sensitive chili pepper cultivars in Vietnam is important not only for in-depth studies of disease resistance-associated molecular mechanisms but also for chili production improvement via molecular marker-assisted breeding in Vietnam.

In India, disease incidence has been reported to vary between 24.59 to 51.72 % Sharma and Sugha (1995). As a disease of minor important but during the last few year bean anthracnose has appeared as a potential threat to the (Sacc and Magnus) Briosi and Cavara is a major limiting factor in reduction of yield in subtropical and temperate regions. Anthracnose is mainly a seed-borne disease caused by a fungus which has a wide host range on many legume species (Goswami et al., 2011).

Eight native strains of Pseudomonas spp. were isolated from rhizosphere of various sugarcane clones on Pseudomonas agar using standard protocols. These strains were characterized for antagonistic traits on red rot pathogen in vitro and Plant growthpromoting (PGP) activities in greenhouse up to 30 days from single node setts in portrays as sett treatment (@109 CFU ml-1 ). The promising isolate was characterized up to species level by PCR amplification of 16S rDNA region using Pseudomonas specific primers. Elite strain was identified as P. putida strain AKP-1.

Present investigation focusing on the post-harvest fungal pathogens, fungal diseases and economic losses of papaya fruits (Carica papaya L.). Matured, ripened and infected fruits of papaya were subjected to isolation of their associated fungal pathogens. Fruit bating method was followed for isolation of fungi from infected papaya fruits. Total 10 fungal genera and 12 species viz. Aspergillus flavus, Alternaria alternata, Alternaria sp.

The genus Colletotrichum comprises ~600 species attacking over 3,200 species of monocot and dicot plants. Colletotrichum species are fungal pathogens that devastate crop plants worldwide. One hundred thirty eight soybean entries received from AICRP (All India Coordinated Research Project) on soybean, were evaluated at Raipur under natural condition during the year 2017-18 to identify sources of genetic resistant against pod blight disease incited by the fungus Colletotrichum truncatum.

The present study was conducted to evaluate the efficacy of aqueous extract and dry extracts of 12 different plant species against C. gloeosporioides the causal agent of mango anthracnose under natural disease epidemics. Significant difference was observed among the extracts in their effect on suppressing the mycelial growth of the pathogen under in vitro conditions. None of the extracts were able to completely prevent the development of the pathogen. However, most of the extracts significantly reduced disease development over the control. Among the fresh plant extracts, at 7.

Chilli (Capsicum annuum L.) is a major spice crop in India. The production of chilli is constrained mainly by fruit rot (anthracnose) caused by Colletotrichum capsici and other species. Use of chemical fungicides is the common practice for control of anthracnose. However, continuous use of chemical fungicides leads to negative effects on environment, soil and human health.

Vanilla planifolia is popularly known as Prince of Spices a fleshy perennial liana grown in and around Western Ghats for its natural compounds used in several ice creams, chocolates and beverages. Fusarium oxysporum f.sp. vanillae is one of the most destructive pathogens causing severe loss to yield and during the survey conducted in 2016, maximum of 25 % incidence was noticed in coorg district. The pathogen was isolated and morphologically identified as F. oxysporum based on the conidial, chlamydosporial and cultural characters. The size of microconidia ranged between 5.97 to 8.

Endophytes are novel sources of natural bioactive compounds. This study seeks endophytes that produce the anticancer enzyme L-asparaginase, to harness their potential for mass production. Four plants with anticancer properties; Cymbopogon citratus, Murraya koenigii, Oldenlandia diffusa and Pereskia bleo, were selected as host plants. L-Asparaginase-producing endophytes were detected by the formation of pink zones on agar, a result of hydrolyzes of asparagine into aspartic acid and ammonia that converts the phenol red dye indicator from yellow (acidic condition) to pink (alkaline condition).
