“…The powdery mildew was controlled by applying different fungicides such as benomyl, bitertanol, carbendazim, dinocap, oxythioquinone, thiophanate-methyl, tridemefon, tridemorph, Vigil, wettable sulfur, etc. [81][82][83][84][85][86][87][88][89]. However, some chemical fungicides such as benomyl, dinocap, and mancozeb were set up most operational at the time of flower cluster expansions and before the cluster opening [90][91][92].…”

Mango, Mangifera indica L., is known to be the king of all fruits due to its delicious taste, marvelous fragrance, and beautiful appearance. However, several infectious diseases caused by many phytopathogens are deteriorating mango quality and quantity. Mango tree and fruit have been affected by about 83 diseases reported worldwide, and in Pakistan, 27 diseases are recognized as more important. Disease control always remains a challenge for the farmers to get optimum production especially due to pesticide resistance. Resistance to fungicide in current days is a major threat to plant disease management. In many cases, plant pathogen resistance could develop naturally; thus, several newly developed chemistries of fungicides remain at high risk. However, research toward an increase of resistance and delay in disease development has been undertaken. Existing fungicide chemistry, sometimes, renamed with new trade name does not satisfy the farmer to apply such fungicides for disease management. However, chemical fungicides are believed to be a significant way to control fungal pathogens or sometimes to inhibit and prevent the development of pathogens. However, due to pathogen resistance development, it is hard to manage plant diseases. Therefore, the impacts of such fungicide management in some important mango diseases are discussed in this chapter.

“…These symptoms may be found alone or in a combination of two or more symptoms in different mango orchards in Brazil or Pakistan 16,17 . The mortality of the tree is usually by the blockage of vascular bundles in the proper flow of nutrients 18 . Losses from this disease vary by region and country and can range from 20-60% 19,20 .…”

Background and Objective:The dieback of mango (Mangifera indica) has become an increasing threat to mango production in Tchad and Cameroon. The present study was conducted to characterize and identify pathogens associated with the mango quick decline tree for the first time in both countries. Materials and Methods: Investigations were carried out through field observations of the symptoms. A simple block experimental design was adopted and the scale was used to assess the incidence, severity and prevalence at the two sites during the dry and rainy seasons. Pathogens associated were isolated using a Potato Dextrose Agar (PDA) medium. The control strategy was evaluated. Results: During the survey, symptoms of this disease were wilting of leaves and branches which gradually progress into dieback, gummosis, rotting of the stem and vascular discolouration. Six fungi, Lasiodiplodia theobromae, Colletotrichum sp., Aspergillus niger and Botrytis cinerea were present in the dry season and the two sites, Curvularia sp. and Schizosaccharomyces pombe occurring in the rainy season only in Cameroon were isolated. The highest incidence and severity rates were obtained during the rainy season, 43.94 and 14.03%, respectively. Kassai variety (25%) was the most susceptible to dieback. The percentage of tree regeneration from the cutting method depends on the attack percentage of the tree. Conclusion: This study suggested that several fungi are associated with this disease in Cameroon and Chad. Molecular analysis and pathogenicity are necessary to upset the control strategy (cutting method) which is efficient when the attack tree is under 50%.
