Abstract. Guava (Psidium guajava Linn.) 147-152. Total surface area of an individual fruit was considered as 100%. Soil amendments: Per cent fruit infected with anthracnose in the untreated plants were significantly higher than in the treated plants (Table 1). and J.S. Studies on anthracnose of guava and its control. But this has not been tried in case of guava anthracnose. Spray solutions were prepared by mixing the definite amount of the chemicals with tap water in bucket. Urea, gypsum, cowdung+SOC and SOC produced highest (4.8-6.8%) surface area infection among all other treatments with SOC supporting the highest. Edition 1st Edition. The apparent symptoms can be observed on both vegetative and reproductive structure. Guava fruit anthracnose as affected by soil amendments with various treatment showing their rate of application, percent fruit infection and per cent fruit surface area diseased at 60 days after treatment, Plants in the same plot receiving no treatment served as control. ), scab (Pestalotiopsis psidii), Alternaria fruit rot (Alternaria alternata) and Phomopsis rot (Phomopsis sp.). Changes in the constituents of guava fruits at different developmental stages. Key words: Anthracnose -Colletotrichum -guava -Egypt Introduction Colletotrichum gloeosporioides (Penz.) ... DISEASES OF GUAVA AND IT'S MANAGEMENT - Duration: 22:14. These factors affect the effectivity too. DISCUSSION Different fungi have been isolated and identified but C. gloeosporioides was isolated from most of the diseased guava fruit sample collected from different districts. Management of Anthracnose Disease of Guava. Imprint CRC Press. In the absence of NPK, plants become weak and at this condition gypsum would not be able to resist the disease singly (Ferdous, 1990). an important fruit of subtropical countries is affected by about 177 pathogens of which, 167 are fungal, 3 bacterial, 3 algal, 3 nematodes and one epiphyte. There are reports that Colletotricum gloeosporioides thrives in media enriched with 0.8% KCl and increasing amount of potassium might be one of the factors promoting the pathogen at fruit maturity rather than earlier (Midha and Chohan 1971,1972). J., 81: 3-4.Malraja, E.G.E.P., 1990. Disease severity was higher in 1987 than in 1988. Results were very promising from the point of environmentally friendly control of guava fruit anthracnose. These results were similar to those achieved by Evueh and Ogbebor (2008) in which Aspergillus sp. Efficacy of fungicides in vitro against some isolates of Botryodiplodia theobromae Pat. Minor elements, Zn, Mn, and B spray gave significant reduction in control of guava anthracnose. Cowdung produced no disease singly and perhaps it suppressed the effect of SOC. Diseases of Fruit Crops. Foliar spray: No disease observed in tilt sprayed plants. Bearing trees, once affected, slowly die away. Tilt and Zinc gave 100% reduction in fruit infection followed by rovral and manganese sulphate, both of which produced 0.8% infected fruits. Timely and accurate detection of the pathogen is important in developing a disease management strategy. Annual report (1987-1988). Apple Guava (light red fleshed) is moderately resistant to anthracnose. Plant other hosts such as Abutilon and Euphorbia around the guava plant to reduce the population of pests on your guava plant Use preventive measure such as yellow sticky traps at 15/ha to attract and destroy the adults pest Integration of various management practices has brought success in some crops (Raut, 1990; Singh et al., 1990; Adisa, 1985).
