Fungicides against mildew case of Potato (Solanum tuberosum .L.) from the Triffa plain, irrigated area of Moulouya

Abstract

The 2016-2017 agricultural season was devoted to prospecting in different farms in the Triffa Plain. Mildew is present in almost all areas of the plain, given the favourable climatic conditions. Around 95% of the potato cultivated areas in the irrigated area of Moulouya are concentrated only in the Triffa plain, from which 51 plots have been identified. This survey showed that a total of 34 plots (476 hectares covering about 22% of the total area under potato cultivation) were attacked differently by the late blight, and the area managed by the Agricultural Valorization Center (AVC 108) showed the highest attack degree .Preventive control is the most used measure by farmers to protect their crops from attacks by this pathogenic fungus. More than 89% of farmers apply chemicals with health protection measures that are often insufficient or totally absent (77% of farmers apply 4 to 6 fungal treatments per cycle). However, the non-rational use of these chemicals revealed serious problems that are harmful to the various environment components, namely fauna and especially human beings’ health. The results obtained in this study recommend the use of rather organic and ecological treatments that are favourable for the preservation of human health and guarantee a sustainable and healthy agricultural production.

Biofungicides for Improvement of Potato (Solanum tuberosum L) Production

“…Since 1800s, the use of fungicides has provided much needed relief in the management of plant fungal diseases in agricultural production. Although the use of fungicide yielded great benefits, the attendant risks to human health, wildlife, and the environment cannot be overlooked [ 38 ]. Fungicides are frequently toxic to nontargeted organisms such as earthworms, microbes, and humans causing ecosystem imbalance [ 33 , 38 , 39 ].…”

Fungicides are chemical agents used in the management of pathogens of plants.…”

“…To overcome the abovementioned consequences, caused by fungal disease pathogens, the use of various artificial fungicides is important. A recent study has shown that some of these agrochemicals or artificial fungicides are toxic to humans with negative impact on the environment, soil microorganisms, insects, and plant pollinators [ 38 ]. However the use of botanicals is attracting much attention from farmers, environmentalist, and consumers.…”

Enhancing Potato Late Blight Control: Triffa Plain Model Assessment (Eastern Morocco)

“…Growers reduce production risks by spraying a series of protective fungicides. This crop is cultivated in large quantities throughout the world, which has contributed to the increase in the persistence of toxic residues in consumable products and the occurrence of resistance to certain active ingredients [4]. Failure to control downy mildew results in costs so high that growers are currently not prepared to risk their crops to follow a spray reduction program.…”
