Pod rot and stem canker, caused by Phytophthora palmivora, are serious diseases of cocoa causing pod losses of up to 63% and the death of up to 10% of trees annually on Kar Kar Island.Papua New Guinea. Annual losses due to black pod may range from 30-90% of the crop. In cocoa, manage- ment of swollen-shoot disease in Ghana probably best demonstrates eradication of millions of trees as a main control measure, this has remained in operation since 1946 (Thresh and Owusu, 1986). (2005) reported using Trichoderma species in vivo to control Phytophthora on cocoa pods. Fruit yield is reduced. Biology and control of Phytophthora diseases of cocoa in Papua New Guinea. Progress with this CRADA continues. Recently, planting materials that are tolerant to the disease have been recommended for planting in areas with high CSSVD prevalence. Aspergillus parasiticus. impact of the disease and allowing time to develop methods of disease management. The only treatment for CSSVD-infected cocoa is to cut out visibly infected trees (eradication). selective spraying of moth resting sites i.e. The objective of the study is to assess the indigenous control practices for pests and diseases of cocoa by farmers in Osun and Ekiti state, Nigeria. Income from cocoa is the main source of cash . | Find, read and cite all the research you need on ResearchGate Cocoa myriads cause die back disease which reduces the growth of cocoa plant. - The cocoa beans were hard to remove from placenta.

Fungal and viral infections represent a major cause of cocoa disease in agriculture. 22), in some cases, can function regardless of the genetic background (16,33). give normal spaces planting operations Black pod, Moniliophthora pod rot, Witches' broom and Watery pod rot are the major diseases of cocoa pods. 5. The objective is to find out whether rainfall and temperature have any effect on these diseases so that plans can be made to control them. We hope that agro-chemical companies and/or their agents will find this bulletin useful on some of their concerns regarding screening of fungicides for black pod disease control in Ghana. secondary pests and diseases. Achievements in Public Health, 1900-1999: Control of Infectious Diseases. Plant protection through biological control is an alternative strategy in agriculture to control pests. That will help reduce the impact of pest and disease infestation on cocoa production. (a) Trichoderma stromaticum colonizing a dead broom. The swollen-shoot virus of cacao is transmitted in the Gold Coast by mealybugs, of which Pseudococcus njalensis Laing is the most important, and these are tended by ants of the genus Crematogaster, which build carton tents over the colonies, thus affording them protection against contact insecticides.An account is given of an investigation which was carried out at Tafo, Gold Coast, between .

Insect-borne viruses: Cococa Swollen Shoot Virus Disease (CSSVD) The diseases and vectors 28.04.2010 LISTEN . Abstract. - Removal and burning of all infected organs before the start of cashew season. Pod diseases of cocoa are widespread in cocoa-growing countries and are responsible for substantial losses in income. The aim of this study was to assess indigenous Trichoderma strains from Bagua Province, Peru, with reference to their antagonistic characteristics in vitro and their potential for in vitro biocontrol against frosty pod rot (FPR) disease. When cocoa is mature and a complete canopy is formed, heavy shading and leaf mulch inhibit weed growth so that only occasional attention to removing woody weeds is required. Contents This study aimed at selecting cocoa tree endophytic bacteria antagonistic to Phytophthora spp. A virus disease of cacao in Ceylon. •Biological control:- Some fungi may attack the vector e.g. control offers safer and environmentally friendlier control option. Cocoa swollen shoot virus disease (CSSVD) is a major disease of cacao (Theobroma cacao L.) in Ghana and other West African countries that grow the crop. 1. The cacao swollen shoot virus disease (CSSVD) which is considered the most economically important cocoa virus disease could account for 15-50% yield loss if the severe strains are involved in infections [2, 3].Since the discovery of this important disease in Ghana, it has been managed through the "cutting out and replanting system" with the aim of removing sources of inoculum from . d'Exportation (EU-STA- BEX) is funding the control of the disease in the ''scattered- outbreak areas'' (i.e., areas where the disease is less widespread than in ''the area of mass infection'' but occurs in groups of outbreaks). Attempts to develop resistant varieties since the discovery of the disease in 1936 have yielded little success. The shading can be reduced once the cocoa trees have formed a closed canopy but some should be retained to reduce water stress and insect damage. Pod-sleeving with plastic bags also reduces attacks of CPB. Cocoa seedlings should be planted 3-4 m (10-13 ft) apart and 3-6 m (10-20 ft) from the shade trees. chemical control of mango anthracnose in 1958 (2) and 1960 (3). 42, december, 1989: 25-35. Pest and diseases of cocoa (presentation) 1. Introduction. - The disease is best controlled by a combination of approaches including cultural, resistance and use of fungicides.

Table 1 lists the major mango fruit, flower and leaf, stem, and root diseases described in the literature. Regular weeding of the cocoa Farm can go a long way in preventing the spread of the disease 2. Pruning of Cocoa 6. For example, Darmano (1994) and Adedeji et al. the Cocoa Diseases and Pest Control (CODAPEC) also known as the cocoa mass spraying as well as farmer education on good agronomic practices through Community Extension Agents [6]. Goals / Objectives 1) Scale-up, monitor, evaluate and validate protocols for biocontrol of important fungal diseases of cacao including field trials set-up for evaluating formulations developed under the previous CRADA; transfer biological control technology to cacao-producing countries; transfer the technology to cacao-growing countries; 2) Develop and apply innovative solutions to the cocoa . 6. In addition, heavy shade also favours the main mealybug vector, Pseudococcoides njalensiis. A purposive random sSampling was used to select 120 cocoa farmers. Cafe, Cacao, The, 23:217-222. Recognition of certain non-pathogenic rhizobacteria by plants can trigger a systemic resistance reaction that renders the host less susceptible to subsequent infection by a virulent agent. Carefully monitor the shade conditions within the canopy. In this mini-review, light is thrown on the prospects of biological control option as an alternative to chemical control of plant diseases in Ghana. PDF | This article basically examined how different agroforestry systems affect cocoa diseases. Regular pruning of the cocoa canopy to less than 4 m in height is also good practice. This pathogen is mostly found in tropical areas where the cocoa trees are located and need rainfall in order to spread its spores. This pathogen if left untreated can destroy all yields; annually the pathogen can cause a yield loss of up to 1/3 and up to 10% of total trees can be lost completely. DISEASES OF COCOA PLANT (CONTD) •CONTROL OF THE DISEASE •Removal of affected trees, most effective method but it is expensive to the farmer. When large outbreaks occur, extensive areas are cleared and replanted ( Thresh and Owusu, 1986 ). Treatment of the disease infected farms identified . Changing climate can also alter the development of pests and diseases and modify the host's resistance and more importantly, the black pod disease is a major threat to cocoa . The most common control methods currently practised are:- clean and frequent harvesting and breaking of pods as soon as possible and destroying/bagging/burying of husks to prevent pupation. Nevertheless, removal of shade, and high forest in general, can also be linked to a greater disease incidence. The identification of endophytes with disease biocontrol activities in the .

Black pod disease of cocoa in West Africa, caused almost exclusively by P. megakarya, still remains one of the most serious constraints on cocoa production. The conventional methods of fungicide application by spraying an aqueous suspension using diverse equipment so far yielded only limited control. Adebola and Amadi (2011, 2012) reported using the fungi Aspergillus sp., communicable-disease-control-manual-general-information 1/3 Downloaded from cocoadev.com on April 26, 2022 by guest Communicable Disease Control Manual General Information Recognizing the showing off ways to get this book Communicable Disease Control Manual General Information is additionally useful. 4, shade can have an indirect, detrimental impact on cocoa by harbouring virus inoculum. Surveys during the 1978 and 1979 harvest season in Togo revealed losses of up to 80%, when no control measures were taken ( Djiekpor et al., 1981 ). The infection causes numerous broom-like shoots to sprout, thus the term "Witches' Broom". The stem is smooth, light gray in color and has prominent leaf scars. Other cocoa pod diseases: The diseases. Olunloyo, A. O. Staying ahead of the pathogen is the best means of control, the pathogen can be greatly reduced if leaf litter is allowed to stay on the ground and if the pathogen gets out of hand chemical control can be used. Therefore, as shown in Fig. (b) Commercial product containing 40 g of T. stromaticum spores that are enough to apply in. Currently (beginning in the year 2000), the European Union-STABilisation des recettes. Although studies in humans with diabetes are lacking, a number of animal studies support beneficial effects of cocoa on glucose control (115, 213). was observed in the south- eastern region of South Vietnam and Koch's postulates were fulfilled using pathogenicity tests on seedlings, leaves and detached fruits. Information was elicited using interview schedule and data were analysed using frequencies, percentages and Pearson correlation. The coconut palm has an erect or slightly curved stem which grows from a swollen base. Partiot M, Amefia YK, Djiekpor EK, Bakar KA, 1978. However, pesticides are used on cocoa in certain circumstances (cases in category 1 of the • Any aspect of cocoa disease management, including chemical, genetic, biological, and integrated control of cocoa pathogens • Innovative and traditional strategies to control cocoa diseases including transgenesis and breeding. The disease is caused by the Moniliophthora roreri fungus and can greatly reduce crop output once the disease is established. This study set out to find the impact of the cocoa swollen shoot disease on the living standards of cocoa farmers in Ghana. Cocoa Growers' Bulletin No. the cocoa black pod disease incidence and it is important to quantify the black pod disease variation due to the effect of climate variables Chang et al., (2016). Control of moniliasis and yield were positively spp. - Occurrence of a exit and entry hole on the pod surface. Additional production losses are caused by insects and other pests such as mirids and the cocoa pod borer. The bulletin will also serve as an assurance to cocoa farmers, consumers - Moreover, the government should provide more incentives of bonuses to the farmers like chemicals. With the value of the cocoa industry throughout the world being so large there are much research and control efforts that . Deaths from infectious diseases have declined markedly in the United States during the 20th century ().This decline contributed to a sharp drop in infant and child mortality (1,2) and to the 29.2-year increase in life expectancy (2). Cocoa swollen shoot virus disease has severely hampered the production of cocoa and the economy of Ghana since pre-colonial days. The disease can be controlled effectively by providing adequate drainage. It can also introduce viral diseases into the plant. Attempts to control cocoa swollen shoot disease by removing trees found with symptoms and immediate 'contacts' at three representative sites in the Nankese District of the Eastern Region of Ghana (G. K. Owusu and J. M. Thresh, unpublished work). in view to produce a new biofungicide capable of controlling black pod disease.Endophytic bacteria were isolated from healthy organs (roots, leaves and stems) of young nurseries of two clones NA32 and P7. The management options for each pest or disease are divided into 'cultural approaches', such as use of resistant varieties, clean seed, crop rotations and good hygiene in the field, and As part of efforts to arrest the decline in cocoa production, the Government of Ghana through Cocoa Board initiated a National Cocoa Diseases and Pest Control (CODAPEC) programme, popularly known as "Mass Spraying" to assist all cocoa farmers in the country to combat the Capsid/Mirid and the Black Pod disease. Control weeds. options (involving pruning, pest and disease control, shade tree management and resistant varieties), which form the basis of integrated management strategies to reduce yield losses from pests and diseases in the cocoa crop. The use of native Trichoderma strains has been proposed as a sustainable alternative to control cocoa diseases. Symptoms: Nymphs and. These are rarely severe enough to warrant control measures other than standard cultural methods (see above). Cocoa Disease and Pest Control (CODAPEC) program which aimed at providing free spraying of cocoa plants to cocoa growing farmers to fight against the rising incidence of diseases and pests' outbreak and more importantly, curb the declining cocoa production and quality of yield. Pesticide Use in Cocoa (v. 19/04/2010 4 Cocoa has a relatively 'green image' and cultural methods (removal of diseased plant parts, etc.) 170 Fred Oduro Sarpong et al. to top. The Frosty Pod Rot disease is a highly contagious disease that affects the fruit of the cocoa plant. are the most proven and cost effective first line of defence against diseases and insects.

Erwin and Ribeiro (1996) estimated a 20 . This paper, therefore, examines the impact The control of cocoa swollen shoot disease in Ghana. programmes, control of pests and disease programmes, fertilizer credits and the privatization of input supply to farmers (International Cocoa Organisation, 2007). Avoid overcrowding of cocoa plant during planting process. The National Cocoa Diseases and Pests Control: achievements and challenges. 5) (4,8,10,12,13). • Diagnosis of cocoa pathogens, including but not limited to DNA, RNA, and protein-based methods This is a trend that has remained constant in the past decade as articles from 2004, 2009 and 2015 report similar loss percentages (Okoffo, et al. Weeds will be an issue wherever the canopy allows light to penetrate or there are aisles provided for access. Cocoa production in Ghana has not matched expansion in the area of cultivated land over several decades. This disease is especially severe in West and Central Africa which contributes 60-70% of the world production of cocoa beans. D. Progress Report: This report serves to document research conducted under a trust between ARS and M&M Mars, Inc. Additional details of research can be found in the report for the parent project 1275-22000-170-00D, Biological Control of Diseases of Cacao, Vegetables and Other Alternative Crops. The results suggest that simultaneous biocon- which is not the case in Peru. Trials were conducted on commercial cocoa plantations to compare the effectiveness of potassium phosphonate when applied as trunk injections, trunk paints and foliar sprays, and trunk injections . For each pest or disease, information is provided on how to recognise the problem, what to do to prevent it occurring and how to control it when it occurs. Harvesting, Fermentation and Drying of Cocoa - Coc/TT: Ag Ext 13: 07 4.

Always remember to spray your plantation with fungicides like the Bordeaux mixture for effective checkmating of the spread 3 . They attach the young shoot of cocoa, introducing toxic saliva into the sap which may kill the plant. The lack of good cultural practices and the impact of disease and pests have frequently been cited as some of the major causes of the poor productivity in the country [].The cocoa swollen shoot virus disease (CSSVD) is one of the most devastating diseases on cacao, and causes . Cocoa Growers' Bulletin, No. Abstract. The disease is caused by Additional studies to confirm these effects in humans are needed, though there is biologic plausibility and preliminary evidence for an insulin-sensitizing effect of cocoa. The cocoa industry in Ghana is however, afflicted by two major plant diseases and one major group of insect pests. Disease control strategies include the use of resistant cultivars, chemicals, biological, botanicals, cultural, physical controls and application of biotechnology, each of which is discussed in this paper.

Nevertheless cocoa, like other tropical crops, continues to be attacked by insects, diseases and other pests that must be controlled effectively and safely. Most attention has been focused on biological control of frosty pod rot (Moniliophthora roreri), witches' broom (Moniliophthora perniciosa) and black pod disease (Phytophthora spp. This chapter discusses the advances in biological control of cacao diseases over the last 15 years. and known tolerance to the disease. A combination of seed dressing and soil drenching with Kocide at a concentration of 0.91 kg in 45 litres of water effectively controls pre- and post-emergence seedling death. Integrated pest and disease management (IPDM) is designed to balance and manage activities in relation to the cocoa cropping Biocontrol offers a potential control strategy for the cacao trees presently under cultivation. (1997). In the management of Phytophthora diseases in Ghana, especially cocoa diseases, much emphasis has been laid on chemical and cultural control as against other control options such as biological control. Black pod disease is a protozoal disease of Cocoa trees. www.platcomventures.com The inventors would like to speak • Conopomorpha cramerella Snellen • Life cycle - 27 to 33 days • Symptoms: - Attack from size of 7cm until 10 weeks before the fruit ripen.
