“…A semi-systemic fungicide, Ridomil 72 Plus (60% cuprous oxide, 12% metalaxyl), and a single injection of Foli-R-Fos 400 (potassium phosphonate, 40% a.i), which is a systemic fungicide and a foliar fertilizer has shown to be more effective than contact copper fungicides in the control of both P. megakarya and P. palmivora [46]. Studies in Ghana have also shown that extended intervals of four-weekly applications using Nordox 75 and Ridomil 72 Plus effectively and economically control black pod disease caused by P. megakarya [47].…”

Cocoa cultivation began with the Olmecs, who were the first humans to consume chocolate as a drink in equatorial Mexico between 1500 and 400 BC. Over the centuries, commercial cocoa cultivation and trade have developed from the Mayans, Aztecs, and through Meso-America under the influence of the Spanish explorers. In 1822, cocoa was first introduced to São Tomé and Príncipe in Africa from where it spread as a plantation crop, with West Africa becoming the major centre of global production. The cultivation of selected hybrid varieties particularly have led to pest and diseases becoming major production limiting factors. This chapter evaluates crop protection techniques developed over the years, and highlights their contribution to yields, production costs, impact on farmers, and the cocoa value chain and ecosystems. We discussed the need to re-evaluate the imbalance of power in the global value chain, the colonial trading systems, and the required investments for integrated disease and pest management systems. The prospects of using modern biotechnological tools to improve cocoa, and how these approaches can reduce the negative impacts of current protection measures on the ecology and production systems are highlighted. Key recommendations have been made for all stakeholders in the cocoa industry to ensure future sustainability.

The sustainability of the cocoa industry in the developing world depends heavily on the preservation of the natural environment. There is, therefore, an urgent need for more research, policies and strategies that will help address and minimize the environmental impacts of cocoa production. This study was conducted using both secondary and primary data sources. The secondary data were collected from documentary sources such as reports from the Ministry of Food and Agriculture and the Cocoa Pests and Diseases Control Programme (CODAPEC). On the other hand, the primary data involved an interview of 15 field officers of the Ghana Cocoa Board. These field officers were purposively selected to help ascertain some of the effects of cocoa production on the environment. The study showed that the environmental impact of cocoa production manifest in the clearance of virgin forests for the expansion of cocoa farms (clearance of 117,240 hectares of forest resources between 2010 and 2015), the clearance of forest for the construction of feeder roads (3000 kilometres of new feeder roads constructed to link cocoa farms to the various marketing outlets) and pollution from the use of pesticides and insecticides. In order to address this problem, there is the need for effective and efficient environmental impact assessment system for large scale agricultural production and the construction of feeder roads to farms. Adequate measures should be put in place by the relevant regulatory agencies such as the Environmental Protection Agency to ensure that the mitigation measures proposed in the environmental assessment process are implemented to minimize the environmental footprint of cocoa production.

The objective of this study was to compare the growth using an organic fertilizer culture comprising wheat straw, mushroom residue or sawdust and dry dung, or plant growth-promoting microbes (PGPM) on the growth conditions and nutritional status of Elymus dahuricus to provide a set of feasible plans for the treatment and restoration of abandoned land exhibiting lower organic matter, calcification, and alkaline soil of the Qilianshan coal mine. Pot experiments were conducted on four groups to study the effect of the characteristics of nutrient absorption of E. dahuricus: (1) original soil with or without the addition of soil bacteria and compound bacteria (nitrobacteria and Pleurotus), (2) different ratios of original soil mixed with different proportions of organic fertilizer, (3) different proportions of original soil mixed with different proportions of organic fertilizer and soil bacteria, and (4) different proportions of original soil mixed with different proportions of organic fertilizer and compound bacteria. Results showed that original soil supplemented with different PGPM, organic fertilizer treatment, and the organic fertilizer combined with different PGPMs was an obvious increase in the growth of E. dahuricus. In particular, 40% of organic fertilizers mixed with the compound bacteria (nitrobacteria and lateral bacteria) exhibited the best growth trend, significantly improving the soil nutrients, the growth of E. dahuricus, and the nutritional status, and providing a reliable scientific foundation for the treatment and restoration of the abandoned land of the Qilianshan coal mine.
