Cocoa swollen shoot virus disease (CSSVD) has severely hampered the production of cocoa in Ghana since pre-colonial days. The Ghana Cocoa Board has put several measures in place to support cocoa farmers in the fight against the CSSVD. This present study captures how the CSSVD affects cocoa farmers and the support systems for such situations. Using a survey design, the study employed the multi-stage sampling technique to select 413 cocoa farmers. A structured questionnaire was used to seek information from the cocoa farmers. A multiple linear regression model was estimated to analyse the data.

Swollen shoot disease (CSSV - Cocoa Swollen Shoot Virus) represents a major threat to cocoa plantations, causing significant economic losses in cocoa-producing regions. This paper proposes a differential equation system based on a Runge-Kutta 4th-order SIR (Susceptible-Infected-Removed) epidemiological model to analyze, predict and control the spread of Swollen Shoot disease in cocoa plantations. This model makes it possible to analyze epidemiological dynamics with stochastic variability, identifying effective strategies for limiting the impact of the disease. The aim of the SIR model is to pr

Two mild strains of Cocoa swollen shoot virus (CSSV), N1 and SS365B, were assessed for their capability to mitigate the devastating effects of CSSV in field trials at the Cocoa Research Institute of Ghana in comparison with noninoculated cocoa plants. Analysis of growth, mortality, and yield of cocoa trees inoculated with the mild strains over a period of two decades between 1996 and 2014 indicated that the cocoa plants inoculated with mild strains performed significantly (P < 0.05) better in the presence of the severe strains (CSSV 1A) than noninoculated cocoa, albeit degenerated over time

Annotation:

The cacao swollen shoot disease of Theobroma cacao L. (cacao) is caused by Cacao swollen shoot virus (CSSV; genus, Badnavirus, family, Caulimoviridae). The virus is endemic to West Africa, where it poses a serious threat to cocoa production. Despite efforts to control CSSV spread by replacement of infected trees with tolerant cultivars and mealybug vector management, the disease is widespread in West Africa. In Trinidad, leaf mosaic and vein-banding symptoms have been observed in cacao plants in the field since the 1940s, and recently at the International Cocoa Genebank (ICGT), a custodian of

Le Cacao swollen shoot virus (CSSV) est un virus infectant le cacaoyer transmis par des cochenilles farineuses de la famille des Pseudococcidae. La maladie qui en découle existe aujourd'hui dans les principales zones de production de cacao d'Afrique de l'Ouest qui représentent 72% de la production mondiale de cacao. Le CSSV a été découvert en 1922 au Ghana et identifié avec certitude dans le Kloto au Togo en 1955 ; le premier isolat étudié moléculairement est l'isolat très virulent Agou1 du Togo. Cet isolat provoque des gonflements de tiges et de rameaux ainsi que des colorations rouge intense

The cytopathological and molecular studies of cacao swollen shoot virus (CSSV) infected cocoa plants, which was aimed at identifying structural and functional changes associated with CSSV infections that can be used as resistant markers has yielded interesting results. Nucleic-acid-rich spherical inclusion bodies, modified plastids, invagination of cell walls, apoptotic cells, massive deposition of phenolic substances in infected cells, in situ localisation of CSSV particles in novel cocoa tissues and the apparent aggregation of starch granules in infected tissues were changes that were found

Cocoa swollen shoot virus disease (CSSVD) seriously affects cocoa production in Ghana, particularly in the areas of mass infection (AMI) in the Eastern Region whilst the disease continues spreading to areas with scatter outbreaks especially in the Western Region. Reports utilising visible diagnostic symptoms on whether the virus is seed-borne and transmissible to seedlings of cocoa (Theobroma cacao L.) have been conflicting. Studies show that visible viral symptoms are not always manifested on all affected parts of infected cocoa trees due to a period of CSSV latency. In this work, molecular d

Cacao swollen shoot virus (CSSV) causes the Cacao swollen shoot virus disease (CSSVD) and significantly reduces production in West African cacao. This study characterised the current status of the disease in the major cacao growing States in Nigeria and attempted a clarification on the manner of CSSV transmission. Two separate field surveys and sample collections were conducted in Nigeria in summer 2012 and spring 2013. PCR-based screening of cacao leaf samples and subsequent DNA sequencing showed that the disease continues to persist in Ondo and Oyo States and in new cacao sites in Abia, Akwa

Background: Cacao swollen shoot virus (CSSV), Cacao swollen shoot CD virus (CSSCDV), and Cacao swollen shoot Togo A virus (CSSTAV) cause cacao swollen shoot disease (CSSD) in West Africa. During 2000-2003, leaf and shoot-swelling symptoms and rapid tree death were observed in cacao in Cote d'Ivoire and Ghana. Molecular tests showed positive infection in only similar to 50-60% of symptomatic trees, suggesting the possible emergence of an unknown badnavirus. Methods: The DNA virome was determined from symptomatic cacao samples using Illumina-Hi Seq, and sequence accuracy was verified by Sanger s

Chocolate is the center of a massive global industry worth billions of dollars annually, yet its future in our modern world is currently under threat. Here, Dale Walters discusses the problems posed by plant diseases, pests, and climate change, looking at what these mean for the survival of the cacao tree. Walters takes readers to the origins of the cacao tree in the Amazon basin of South America, describing how ancient cultures used the beans produced by the plant, and follows the rise of chocolate as an international commodity over many centuries. He explains that most cacao is now grown on

This chapter deals with cacao swollen shoot disease, which has wreaked havoc in cacao-growing areas of West Africa since its first report in the early part of the twentieth century. First thought to be caused by drought, it was subsequently found to be caused by a virus—the cacao swollen shoot virus—and to be transmitted between cacao trees by several species of mealybug, including Formicococcus njalensis. Today, we know that ten viruses are involved in causing the disease, which is restricted to West Africa. The chapter examines the transmission of the virus and the efforts made to restrict i
