Minor tropical fruits are grown on a small scale and provide income to smallholder farmers. The cultivation of these fruit crops indirectly contributes to the economy of producing countries as well as to food and crop security. Dragon fruits, guava, passionfruit, lychee, longan, mangosteen, durian, and rambutan are common minor fruit crops. In recent years, the international trade of some of these minor tropical fruits, particularly dragon fruit, passionfruit, guava, and lychee, has increased due to their nutritional value, with various health benefits. Similar to other crops, minor fruit crops are susceptible to fungal and oomycete diseases. These diseases negatively affect the yield and quality of fruit crops, leading to substantial losses. In this context, the knowledge of disease types and causal pathogens is fundamental to develop suitable disease management practices in the field as well as appropriate post-harvest treatments.

Biological control represents an important approach to manage plant diseases. Blights of leaf, panicle and fruits caused by Alternaria alternata and the wilt caused by Fusarium solani are important diseases of litchi. Hence, as an alternative to chemical fungicides, biological control by Trichoderma spp. to manage pathogens of litchi was explored. The aim of this study was to isolate native Trichoderma spp. from litchi orchard ecosystem and to evaluate antagonistic potential and its biological fitness so as to develop a commercial formulation for field application to manage litchi diseases. The results showed that out of nine isolates of Trichoderma spp. isolated from litchi rhizosphere soil collected from different litchi orchards located in Muzaffarpur, Bihar the Trichoderma viride isolate NRCL T-01 showed highest antagonistic activity in dual culture bioassay against litchi pathogens, A. alternata (70.5% inhibition) and F. solani (60.9% inhibition). The volatile and non-volatile compounds produced by the isolate could effectively inhibit both the pathogens. It could grow well at temperature between 15 to 45 °C, tolerated pH between 4.0 to 7.0 and high salt stress (0.25-1.50 M NaCl). The talc based formulation of the T. viride isolate NRCL T-01 effectively controlled litchi wilt pathogen F. solani on challenge inoculation in glasshouse condition as well as naturally affected litchi trees in orchards. Additionally, the isolate showed good plant growth promotion activity acting as a biofertilizer and helping air-layers to establish better in fields. Further study is being conducted to validate the potential as a commercially-viable product under farmers' field conditions.

Background: Lotus, Nelumbo nucifera Gaertn is Vietnam’s symbol and Buddhism’s flower and plays an essential part in rural Vietnam’s economy as all aspects of lotus could bring benefits to farmers. But, unfortunately, lotus yield in Vietnam is seriously affected by various plant diseases. Among them, leaf blight is currently emerging as one of the primary diseases devastating lotus crops in Vietnam, in which there are large necrotic parts on lotus leaves, flowers and seeds. Methods: Aloe barbadensis extract was used for synthesizing silver nanoparticles. Leaf blight lotus leaves were collected to isolate pathogenic fungi-infection of isolated pathogenic fungi on the healthy lotus and then identify hidden mold by 28S rRNA sequencing. Determination of in vitro minimal inhibition concentration of nano-silver was conducted according to Azizi. The reduction of disease symptoms and biological characteristics of the treated lotus was observed. Result: Morphological analysis and molecular identification of 28S rRNA sequencing showed that the pathogenic microorganism was Mycoleptodiscus indicus (M. indicus). Both in vitro antifungal activity and in vivo treatment of leaf blight lotus using a nano-silver solution showed that 30 ppm of nano-silver was the minimal inhibition concentration (MIC) for totally eradicating M. indicus growth. This was the first time M. indicus was reported to infect and cause leaf blight on a lotus. Previously, M. indicus was a well-known plant pathogen that could cross-kingdom infect humans and animals. Thus, the fact that lotus is widely cultured in Vietnamese rural could increase the chance for M. indicus to spread; hence, this raised the alarm about its potential harm to plants, humans and animals. And, significantly, it revealed nano-silver as a possible approach to prevent M. indicus.
