Least colony growth was observed in case of Derosal which gave effective control against C. gloeosporioides followed by Bayletan, Daconil, Ridomil Gold, Mancozeb and Alliete. It has slander like trunk with smooth red green bark. Prevalence and control of guava fruit anthracnose. )., Eurasia Publishing House (P) Ltd., New Dehli, pp: 264-285.Sastry, M.P., 1965. Anthracnose of guava, caused by the fungus Colletotrichum gloeosporioides, is a major factor limiting worldwide guava production. Disease severity in Sheikhupura, Sargodha, Faisalabad, A survey was conducted in three wholesale fruit market in Dhaka city during October 2012 to September 2013 to record postharvest diseases of mango, guava, papaya and jujube fruits collected from different parts of the country. M.Sc. Fruit infection in urea and TSP treated plants also increased but still at slower rate. This disease can cause considerable postharvest losses and can affect young developing flowers and fruit. rot (Rhizopus stolonifer), Aspergillus rot (Aspergillus flavus), stem end rot (Botryodiplodia theobromae), Stemphylium blight (Stemphylium sp. OCCURRENCE OF GUAVA ANTHRACNOSE IN PUNJAB (PAKISTAN) AND ITS INTEGRATED MANAGEMENT In other treatments fruit infections were reduced gradually with time comparatively more readily with PK+ZnSO4 and NPK+ZnSO4+ Gypsum and less slowly with cowdung+MOC (ghani) and MOC (mill) (Fig. The Second Edition includes chapters on the following: Sterilization of culture apparatus and culture media Culture of pathogens with detailed techniques for 61 fungi and selected bacteria Long-term storage of plant pathogens Detection and estimation of inoculum for 28 soilborne fungal pathogens and 5 bacterial genera-15 methods for airborne inoculum and 13 methods for seedborne pathogens Establishment of disease and testing for disease resistance Work with soil microorganisms Fungicide evaluation Biological control Bright-field microscopy. Chaudhry, 1990. Results of investigation revealed that C. gloeosporioides was established as major causal organism. These spots gradually enlarge to 5 – 6 mm in diameter; coalesce to form a corky hard lesion having cracks. But their combination produced more disease in comparison with their single effect. It is hardy crop and is cultivated successfully even in neglected soils. Out of six fungicides tested against Colletotrichum gloeosporioides, systemic fungicides gave more good results than non systemic fungicides. Similar trend was observed in SOC, cowdung+SOC and gypsum treated plants but at apparently at a slower rate. Management Spraying the trees with Bordeaux mixture 1.0 % or copper oxychloride 0.2 % or Carbendazim 0.1% before the onset of monsoon reduces the disease incidence. Because fluazinam, iprodione+propineb, and triflumizole were found effective against the seed pathogens, these were subjected for field-testing. Anthracnose of mango on inflorescence caused by Colletotrichum gloeosporiodes is among those diseases responsible for low yield of crop in Pakistan. One set of plants were kept for control treatment receiving no manures and or fertilizers. Hafizabad, Jhang and Chiniot districts was recorded as 55%, 42%, 35%, 46%, 31% and 22% respectively. Tilt and rovral were sprayed at the commercial rates (0.2%). The characteristic symptoms consist of sunken, dark colored, necrotic lesions. 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.Wilt is the most important disease of guava. Remove and burn any infected plants in your guava plantation; Avoid too much water around your guava trees; Spray copper-based fungicides such as mancozeb 75% wp @2.5gm/liter of water and oxychloride 50% wp @4mg/liter; Preventions of Guava Anthracnose Disease Survey of fruit anthracnose of guava in BAU-GPC was carried out in the year 2013 and mean annual air temperature 29.67ºC (max) and 21.16 ºC (min), rainfall- 212.58 mm, relative humidity- 84.14% and soil temperature 26.95 ºC at 20 cm. (1993). Indian Phytopathol., 38: 427-430.Chapman, H.D., 1975. Maximum disease incidence was recorded in Band Bosan (43.66 %) followed by Shujabad (37.99 %) and Qadir Pur Rawan (36.99 %) whereas minimum was in Nawab Pur (34.66 %). However, disease under natural condition is regulated by natural factors temperature, humidity and rainfall which vary from season to season and year to year. See active ingredients product application restrictions and more. Guava book. Management of mango anthracnose consists of five ap-proaches: • site selection • cultivar selection • cultural practices in the field (sanitation, plant spacing, intercropping, etc) • fungicide sprays in the field • postharvest treatments (physical, chemical). One hundred percent of plants and 90–100% of fruits were severely diseased. The apparent symptoms can be observed on both vegetative and reproductive structure. Seed decay of soybean caused by Diaporthe phaseolorum, Colletotrichum truncatum and Cercospora kikuchii is a serious disease when soybean is harvested under warm and wet weather conditions. & Sacc., the causative agent of guava anthracnose (Srivastava and Tandon, 1969; Tandon and Singh, 1970; Adisa, 1985), is known to show variations among its isolates (Sutton, 1980; Senaratna eta!., 1991). While Alliete showed 74.5 mm at 60. appeared that response of each fungicide is different. Bearing trees, once affected, slowly die away. Least colony growth was observed in case of Derosal at 60 ppm, 20 ppm and 40 ppm with 7 mm, 10 mm and 11.6 mm growth respectively. Cowdung produced no disease singly and perhaps it suppressed the effect of SOC. It has been reported in all guava-growing areas around the world where high rainfall and humidity are present. Guava (Psidium guajava Linn.) A severidade e incidência da doença foram avaliadas a cada dois dias durante 12 dias. Article. They found oil cake increased the disease severity while high dose of NPK reduced it. Integration of various management practices has brought success in some crops (Raut, 1990; Singh et al., 1990; Adisa, 1985). Each type was isolated from peach, apple, and pecan. Rev. Penz. Among the class-1 antagonists ,T1 isolate of T. viride showed best hyperparasitic activity(3.30 cm) followed by. But keep in mind that it weakens it and makes it more susceptible to other diseases, frost injury, environmental stress such as drought and extreme temperatures, and insect damage. The implications of these results in view of the future management strategies of Armillaria root rot of tea in Kenya are discussed. Nitrogen enhances the development of guava anthracnose. Pages 14. eBook ISBN 9780429504907. Urea, gypsum, cowdung+SOC and SOC produced highest (4.8-6.8%) surface area infection among all other treatments with SOC supporting the highest. Acervuli are formed on fruit stalks. Cowdung+MOC (ghani), TSP, Urea amended plants suffered from moderate infection of fruit anthracnose. Saksena, 1978. Management Ensure trees receive adequate fertilization, irrigation and and are properly pruned to avoid stress on the plants and promote air circulation through the canopy; periodic applications of a copper based fungicide is usually enough to control the disease. Deficiency of any one of the above elements makes plants vulnerable to disease. Topsin-M was significantly superior to all other chemistries at 100, 75, 50 and 25 ppm concentrations followed by the Bavistin and Benlate whereas Antracol and Captan could not prove to be responsive against the fungus. Uprooted and burnt wilted plants. Chohan, 1972. Foliar spray: Two fungicides namely tilt [1-2-(2,4-Dichlorophenyl)-4-propyl-1, 3di ortho oxalen-2-Elmethyl-1 H 1,2,4-Tryozole] and rovral [1-isopropyl carbomoyl-3-(3,5-Dichlorophenyl) hydantoin] and three minor elements namely manganese (MnSO4), boron (HBO3) and zinc (ZnSO4,) were sprayed as solution on to the trees. It has been reported in all guava-growing areas around the world where high rainfall and humidity are present. But this has not been tried in case of guava anthracnose. Anthracnose caused by Gloeosporium psidii (Colletotrichum psidii) is one of the major diseases causing significant losses in the production of guava. Department of Plant Pathology, Bangladesh Agricultural Research Institute, Joydebpur, Bangladesh, pp: 64-67.Rahman, M.A. It is hardy crop and is cultivated successfully even in neglected soils. Anthracnose of guava treatment. It is the fourth important fruit of the Pakistan. Effect of temperature, wetness duration and cultivar on the development of anthracnose in guava fruits, Guava fruit anthracnose and the effects on its nutritional and market values in Ibadan, Nigeria, In-vitro antagonism of Trichoderma sp. Lukade and Rane (Lukade and Rane, 1994) reported that application of N in combination with phosphorus was found effective in reducing the root rot of safflower and when these inorganic amendments applied singly, they were ineffective against root rot disease. Based on the above discussion it is evident that soil amendments with manures and fertilizers caused marked effects on guava fruit anthracnose infestation when no disease developed. Cowdung, MOC (mill), MP, ZnSO4, cowdung+MOC (mill) and K+ZnSO4 results 100% reduction in fruit infection over control. Soil solarization. Anthracnose is the most commonly observed disease that affects both pre- and postharvest management of guava. Occurrence of guava anthracnose in Punjab (Pakistan) and its integrated management, POSTHARVEST DISEASES OF SELECTED FRUITS IN THE WHOLESALE MARKET OF DHAKA. Estas informações geradas nesse trabalho serão úteis tanto para o desenvolvimento de sistemas de aviso fitossanitário quanto para aumentar o tempo de vida de goiabas após a colheita. Bangladesh J. Birds are predators that will consumed your ripe or overly ripe guava, the antidote is to harvest your ripe guava on time. Minor elements, Zn, Mn, and B spray gave significant reduction in control of guava anthracnose. Anthracnose: Colletotrichum gloeosporioides. and J.S. MANAGEMENT Proper sanitation. Spraying were started from early fruit stage (fruit setting) and was continued for 3 sprays at an interval of 15 days. © 2008-2021 ResearchGate GmbH. and S. Hossain, 1988. Use neem oil, plant resistant variety, maintain good cultural agronomy management. Anthracnose of guava. It is a small or shrub like evergreen tree. For this, disease occurrence was comparatively lower in combined application of cowdung+SOC. Anthracnose can be a problem in semi-arid climates (and probably arid ones), too. Rane, 1994. Diagnostic Chriteria for Plant and Soils. Control measures of the major diseases are briefed below: Wilt disease: Wilt is the most serious fungal disease. Aspergillus flavus and Pseudomonas florescence were found to be the most effective treatments among fungi and PGPR evaluated respectively in inhibiting the colony growth of C. gloeosporioides. All rights reserved. Chohan, 1970. The treatments with their doses are shown in Table 1. Effect of certain nutrient elements on the incidence of Colletotrichum capsici in chilli. FUNGI ASSOCIATED WITH GUAVA ANTHRACNOSE AND MANAGEMENT OF COLLETOTRICHUM GLOEOSPORIOIDES THROUGH BIOLOGICAL AND CHEMICAL MEANS. Fungicides tested were azoxystrobin, benomyl, captan, copper hydroxide, fluazinam, kresoxim-methyl, prochloraz, pyrimethanil and trifloxystrobin. Guava production is most successful in regions where flowering and fruiting occur in the dry season, which does not favour anthracnose, styler end rot. The organic manures cowdung at 10 kg/tree, Mustard oil cake (MOC) (ghani), MOC (mill), Sesame oil cake (SOC) at 2 kg/tree and fertilizers urea, Tripple Super Phosphate (TSP), Muriate of Potash (MP), ZnSO4, Gypsum at 0.3, 0.3, 0.35, 0.005 and 0.01 kg/tree respectively were applied separately and in six combinations. For most of this article the. It is a matter to be looked into that how the management practices work under heavy disease intensity and favorable weather. As condições ambientais podem afetar tanto o desenvolvimento do patógeno quanto a taxa de amadurecimento dos frutos. Anthracnose: Colletotrichum gloeosporioides. International Journal of Pest Management Volume 47, 2001 - Issue 2. Indian J. Mycol. The efficacy of 21 fungicides against the pathogens was evaluated in vitro. Disease severity was low during the experimental period, perhaps because of low inoculum pressure or unfavorable weather. Anthracnose is a common fungus that is a problem for a wide range of plant types, including guava. 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. Tiny dark brown to black spots appear at, Five isolates of Trichoderma viride and two isolates of Beauveria bassiana were screened against Colletotrichum gloeosporioides for their antagonistic potentiality by dual culture plate method. Two of these (copper and benomyl) are for orchard use and one (prochloraz) is for postharvest use. Mango, Avacado, Lychee, Longan, - Duration: 7:46. Soil amendments: Soil amendments by organic manures and inorganic fertilizers were applied separately and in combination during early May and late October 1992. Gypsum alone had no effect on development of disease. These studies whould be useful for high quality guava fruit production and to control this disease. Guava. The guava tree is attacked by 80 insect species including 3 bark eating. It sounds like anthracnose or black spot this diseases in the mangos will be a real problem this year because of all the wet weather. Urea and TSP had less effect over disease development when these were used singly. TSP, Cowdung+MOC (ghani) were less effective and urea, gypsum, cowdung+SOC and SOC were ineffective. Timely and accurate detection of the pathogen is important in developing a disease management strategy. Anthracnose is a common fungus that is a problem for a wide range of plant types, including guava. Continued observation on fruit infection revealed that infections on untreated fruits increased with time, which at the time of 60 days after soil amendments resulted in 9.2% fruit infection. C. gloeosporioides was inhibited and this is as a result of the production of metabolites. The C. gloeosporioides isolates were more aggressive on guava fruits than the other tested fruits, like apple, pear and mango. Effect of different chemicals on mycelial growth of C. gloeosporioides: Systemic fungicides gave good results than non-systemic fungicides. By the application of these strategies the anthracnose problem can be managed properly with better economic benefits and small risk of health hazard effects. Abstract. MOC and SOC were decomposed in water for 3 days before application. More promising result (99% over control) was found in the present study spraying rovral wp without using sticker. Wilt is the most important disease of guava. Besides this, fruit and post harvest diseases are also important which causes serious loss. The isolates with highest inhibitory properties tended to produce a pigment into the nutrient broth. With respect to the farmers information most of the orchards showed heavy soils, sub soils with hard pan, a high soil pH, unbalanced fertilizer applications, poor irrigation, intercropping with other crops and zero pruning. Apple Guava (light red fleshed) is moderately resistant to anthracnose. The Second Edition of this bestseller brings together basic plant pathology methods published in diverse and often abstract publications. Annual research review (1988-1989). Anthracnose: Gloeosporium psidii. Omar A. Abdul Wahid Department of Botany, Faculty of Science , Suez Canal University , Ismailia, 41522, Egypt . The characteristic symptoms consist of sunken, dark colored, necrotic lesions. These results corroborate with the reports of Hossain and Meah (1992) who reported that rovral flo and rovral wp when used with sticker reduced 90-96% guava fruit infection. Pakistan Journal of Agricultural Sciences. Anthracnose can survive on … biological control of Colletotrichum gloeosporioides by Aspergillus flavus gave good results and appeared to be the most effective against the test pathogen followed by Aspergillus niger and Trichoderma harzianum, while Aspergillus fumigatus gave poor results. 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. Guava (Psidium guajava L.) is an important fruit of subtropical countries. This disease can cause considerable postharvest losses and can affect young developing flowers and fruit. By the application of these strategies the anthracnose problem can be managed properly with better economic benefits and small risk of health hazard effects. Foliar spray: All the spray treatments significantly reduced fruit infection over control. This treatment proved ineffective. Severely anthracnose infected fruits become fully unfit for consumption and lose food value and market price. pathogen has a wide host range and successfully invades, 50.93 to 89.44% reduction of the radial growth of, It could be used as the substitute for the other fungi, the best for control of disease followed by calixin, baytan, give control for brown rot when fruits were inoculated 3, Bayletan and Riodomi Gold with alternating programme.
