Endophytic fungi and their potential in controlling white root disease of cashew

Abstract

PPSCashew (Anacardium occidentale L.) has been grown on a plantation scale and has become a significant plantation commodity in some regions of Indonesia, such as Bali, Nusa Tenggara, and Sulawesi. This plant produces "true" fruit known as cashew nuts. Recently, market demand for cashew nuts has increased in domestic and international markets, especially Europe and America. In 2019/20, cashew nuts were the third most popular tree nut (after almonds and walnuts) and contributed 17% of global tree nut production (International Nut and Dried Fruit Council Foundation 2020). As one of the cashews nut-producing countries, Indonesia ranks 7 th as the largest producer globally (Ministry of Trade of Indonesia 2016). Furthermore, the data released by the Directorate General of Plantations of the Ministry of Agriculture (2019) showed that the total area of the national cashew nut was 494 268 ha until 2018, which was dominated by smallholder plantations. Therefore, 99.8% of Indonesia's cashew nut production came from smallholder plantations.Poor field management and sanitation are a weakness of smallholder plantations, so cultiva-

Antioxidant Activity of Endophytic Fungi Isolated from Cashew (Anacardium occidentale) Leaves

“…Cashew tree parts can be utilized to combat free radicals and cure infectious diseases brought on by bacteria and fungus. [17][18][19] The compounds contained in cashew leaf extract have been reported to contain ascorbic acid, quercetin, quercetin 3-o-rutinoside, quercetin 3-o-rhamnoside, zoapatanolida A, agathisflavone, anacardisin, pentagalloylglucose, methyl gallate, flavonoids, tannins, triterpenes, saponins, alkaloids. These ingredients have been proven as antioxidants and anticancer.…”
