ABSTRACT Theobroma cacao, the source of chocolate, is affected by destructive diseases wherever it is grown. Some diseases are endemic; however, as cacao was disseminated from the Amazon rain forest to new cultivation sites it encountered new pathogens. Two well-established diseases cause the greatest losses: black pod rot, caused by several species of Phytophthora, and witches’ broom of cacao, caused by Moniliophthora perniciosa. Phytophthora megakarya causes the severest damage in the main cacao producing countries in West Africa, while P. palmivora causes significant losses globally. M. perniciosa is related to a sister basidiomycete species, M.

Background: Phytophthora megakarya is an invasive pathogen endemic to Central and West Africa. This species causes the most devastating form of black pod disease of cacao (Theobroma cacao). Despite the dele- terious impacts of this disease on cocoa production, there is no information on the geographic distribution of P. megakarya. Aim: In this study, we investigated the potential geographic distribution of P. megakarya in cocoa-produc- ing regions of the world using ecological niche modelling. Methods: Occurrence records of P. megakarya in Central and West Africa were compiled from published studies. We selected relevant climate and soil variables in the indigenous range of this species to generate 14 datasets of climate-only, soil-only, and a combination of both data types. For each dataset, we calibrated 100 candidate MaxEnt models using 20 regularisation multiplier (0.1−1.0 at 0.1 interval, 2−4 at 0.5 interval, 4−8 at 1 interval, and 10) and five feature classes. The best model was selected from statistically significant can- didates with an omission rate ≤ 5% and the lowest Akaike Information Criterion corrected for small sample sizes, and projected onto cocoa-producing regions in Southeast Asia, Central and South America.

Significant positive correlations were found between rainfall records and pod rot incidence when assessed after a 1-week lag. Disease distribution across various pod developmental stages showed that immature pods were the most susceptible to P. megakarya attack. Weekly obser- vations of the pod distribution and disease progression at various developmental stages on cacao trees sprayed with fungicide Ridomil, Trichoderma asperellum biocontrol agent (strain PR11), or untreated control trees indicated that the total pod production and the inci- dence of black pod rot was significantly different between the treatments.

Exemplary is core metabolism reduction Full list of author information is as parasites adapt to a particular host, while the accessory genome often available at the end of the article maintains a high degree of diversification. However, selective pressures acting on the genome of organisms that have undergone lifestyle or host change have not been fully investigated. Results: Here, we developed a comparative genomics approach to study underlying adaptive trends in oomycetes, a eukaryotic phylum with a broad range of economically important plant and animal parasitic lifestyles. Our analysis reveals converging evolution on biological processes for oomycetes that have similar lifestyle. Besides, we find that certain functions, in particular carbohydrate metabolism, transport, and signaling, are important for host and environmental adaption in oomycetes. Discussion: Given the high correlation between lifestyle and genome properties in our oomycete dataset and the convergent evolution of fungal and oomycete genomes, we have developed a model that predicts plant pathogen lifestyles with high accuracy based on functional annotations.

The programme was particularly concerned with understanding the current issues surrounding chemical use by smallhold farmers in Ghana and with ensuring that application systems are optimized to the benefit of both farmers and consumers. Through an extensive survey across 4 regions of Ghana, the project examined the human and socio- economic constraints to the adoption of disease management technologies among smallholder farmers and identified key issues requiring resolution in the development of effective and viable disease control measures.

Received 25 June, 2020; Accepted 10 August, 2020 Phytopathogenic fungi, Phytophthora palmivora and Phytophthora megakarya continue to be a major threat to cocoa production worldwide. To counter these drawbacks, producers rely heavily on agrochemicals leading to pathogen resistance and environmental hazards. There is also increasing demand by cocoa consumers for pesticide-free seeds. Therefore, biological control through the use of natural microbial antagonists is more rational and safer crop management option. The plant-associated Bacillus amyloliquefaciens, ESI was selected in vitro, among seven other Bacillus species as the most promising, using the zone of inhibition techniques. The B. amyloliquefaciens together with two other laboratory contaminants, Aspergillus and Penicillium spp. were used to control black pod disease of cocoa caused by P. palmivora and P. megakarya on detached cocoa pods and under field conditions.

Black pod, caused by Phytophthora spp., is the only major cacao disease that has been reported in Hawaii but distribution and molecular identification are lacking. To determine the species of Phytophthora affecting Theobroma cacao, a sampling trip was conducted on Hawaii Island and Oahu. Ten isolates of Phytophthora palmivora were obtained from diseased cacao on Hawaii Island, but none from Oahu, despite the presence of symptomatic pods. No other Phytophthora species were found. Laboratory studies showed that all isolates produced lesions on unwounded cacao pods, but they differed in terms of their temperature–growth responses. Fungicide sensitives for a subset of isolates (n = 4) were determined using media amended with a range of fungicide concentrations. The Hawaiian isolates of P. palmivora were more sensitive to mefenoxam, chlorothalonil, and fosetyl-Al, than isolates Citation: Puig, A.S.; Quintanilla, W.; n n P.

Head of Department Signature Date ii ABSTRACT The control of the blackpod disease of cocoa is mainly by the application of copper- based fungicides. However, copper fungicides used might have negative impact on soil pH, available phosphorus and organic matter and may also persist in cocoa beans which can negatively impact on the health of consumers. A study was conducted in selected cocoa farms in the Ahafo-Ano North district of the Ashanti Region to evaluate the effect of copper contained in fungicides on the soil, cocoa beans and leaves. Soil analysis showed that the amount of both extractable and total copper in the soil did not vary significantly with increasing soil depth, but varied significantly (p<0.001) with the age of cocoa plantation.

Accepted 17 March, 2018 Fungal endophytes (Geniculosporium sp.) isolated from cacao leaves were screened for biological control of Phytophthora megakarya the cacao black pod disease pathogen, using Cacao Pod Husk Pieces (CPHP). CPHP were pre-treated with spore suspensions of Geniculosporium sp. [BC13 (GJS 01- 196), BC108 (GJS 01-192), BC118 (GJS 01-197), BC177 (GJS 01-198)], and were infected with P. 5 megakarya zoospore suspensions (10 zoospores/ml) .
