Dark-green streaks and rings appear in the leafstalks and stems. Foot rot of papaya Disease symptoms. But mildew does not rot papayas as does the blight disease.

SURYA, 851_58 INFLUENCE OF NUTRITION AND VAM FUNGI ON PLANT GROWTH PARAMETER, PHYSIO-CHEMICAL COMPOSITION OF FRUIT AND YIELD OF PAPAYA (CARICA PAPAYA L.) CV. This disease is most severe during rainy periods and the disease progresses, small black spots (spores) can be seen on the underside of leaves. The application of insecticide to reduce the incidence of leafhopper vectors can be beneficial. The fungus survives in soil and enters through wounds in the plant stem. PAPAYA ROOT ROT. Infection is first apparent on the leaves as small darkened areas, which later become white powdery spots. If leaves are severely infected, and they turn brown and die. Viral diseases, such as that caused by the Papaya ringspot virus (PRSV) are even more deadly. The disease attacks the papaya plants of all age groups but is most serious on young Papaya plants. Once disease appears in a field, the disease can be the main concern due to its ability to spread among plants and destroy fruits rapidly during windy, rainy periods. Black spot Asperisporium caricae Cercospora papayae Phomopsis caricae-papayae. Anthracnose Colletotrichum gloeosporioides. Then, preventive spraying against this disease is done about every 2 weeks in wet locations. Such Papaya fruits are elongated and reduced in size. KESAR KING, 851_12 RCTP-1: A NEW HIGH YIELDING SELECTION OF PAPAYA FOR TRIPURA, 851_13 GENETICAL STUDIES IN PAPAYA (CARICA PAPAYA L.), 851_14 MUTAGENIC STUDIES IN PAPAYA (CARICA PAPAYA L.), 851_15 EFFECT OF EMS ON GERMINATION, GROWTH AND SENSITIVITY OF PAPAYA (CARICA PAPAYA L.) CV. The Anthracnose disease prominently appears on green immature fruits. Fungal diseases are a major production problem for papayas which typically require frequent and large amounts of fungicides applied to orchards. Then, spaying with Copper Oxychloride (3 g/liter of water) or Carbendazim (1 g/liter of water) or Thiophanate Methyl (1 g/liter of water) at 15 days interval effectively controls the disease. Appropriate protective fungicides applied as a preventive measure are the best for managing anthracnose disease. It develops under a web between and around fruits and along stems of plants. Application of Carbofuran (1 kg a.i./ha) at the time of sowing seeds followed by 2 to 3 foliar sprays of Phosphamidon (0.05%) at an interval of 10 days starting from 15 to 20 days after sowing effectively checks the population of aphids. Older leaves are most likely to be affected. The purpose of this project is to develop transgenic papaya lines that will be resistant to a wide range of fungal diseases. Management – Applications of suitable protective fungicides (mancozeb) at intervals of about 14 to 28 days provide satisfactory control of the disease. The-fungal diseases of papaya attacking in India are reviewed here. Commercial papaya production has been hampered worldwide due to the high susceptibility of the crop to different fungal, viral, and bacterial diseases. This project proposes to develop a papaya with broad resistance to the many different fungal pathogens through genetic transformation of the host. Symptoms – Circular water-soaked or brown lesions on older plant leaves; centers of lesions become bleached as they mature; plant leaves curl and turn brown; raised lesions on trunks; sunken circular lesions on fruit. Fungal diseases; Alternaria fruit spot Alternaria alternata. As the spots develop, they become sunken, turn brown or black, and may enlarge to 2 in. Sawant, S. G. and Gawai D. U. COORG HONEY DEW, 851_92 INCORPORATION OF PAPAYA FOR FORTIFICATION OF β-CAROTENE IN RICE STICKS, 851_93 EFFECT OF ULTRASOUND TREATMENTS IN PAPAYA JUICE PROCESSING. Symptoms. SOLO, 851_61 EFFECT OF FERTIGATION ON GROWTH AND YIELD OF PAPAYA CV. Symptoms – The young Papaya plants are attacked by the nymphs and adults. Symptoms – This is a disease of young seedlings and lesions are seen on the stem at or just above soil level. Damping-Off (fungus – Rhizoctonia solani): This is a disease of young seedlings. Insufficient water, disease, or attack by nematodes can all cause Papaya trees to wilt. Fruits for exports must be subjected to hot water treatment or fungicidal wax treatment. Papayas require plenty of water to grow tasty fruit, but the plants do not tolerate wet feet. Introduction to Papaya pests, diseases, and their control procedure. Severely infected leaves can become chlorotic and distorted before falling. The disease enters orchards from infected papaya leaves in adjacent orchards. The stem becomes watery and shrinks, followed by death of the plant. Symptoms are first evident as small, yellow areas. Aphids (Aphis gossypii and Myzus persicae). The fungus is spread by wind and rain disease emergence is favored by high temperature and humidity. Papaya requires regular fertilizer applications to meet the nutrient requirements for Papaya fruit production. The fungus survives and reproduces on papaya plants only. Papaya ring spot virus (PRSV) of apaya pests and diseases. Water soaked patches appear on the stem near the ground level. With widespread infections, the recommendation is to remove all affected Papaya plants. Management – Copper has been widely proposed as offering a level of control of this disease. The fruit has thin skin and thus rough handling leads to heavy losses due to several rots caused by fungi and bacteria. Papaya ringspot disease can cause symptoms on leaves, stems and fruit. Also, they are susceptible to disease and can be damaged by chemicals used to treat diseases. Acta Horticulturae, (851), 443–446.
