“…Small or medium scale farmers usually practice polyculture or diverse crop cultivation where different crops are grown in small area. This practice leads to cross contamination, infection and disease spreading across different crops grown (Iverson et al, 2014;Kiran et al, 2021;Loomis, 2022). A preliminary identification of Begomovirus can help to describe (provisionally) the probable evolution and diversity of Begomovirus.…”

Aim: To study the disease incidence and diversity of Begomovirus infection and crop loss due to spread of virus across different districts of North Bengal. Methodology: Several fields in different districts of North Bengal were surveyed and potential begomoviral-infected samples were collected for further analysis. Total DNA extraction, PCR analysis, sequencing and phylogenetic analysis were conducted. Results: During 2019-2021, ten fields of each district were surveyed and begomoviral occurrence was observed in almost every field. The disease incidence in different districts varied from 15-45%. The highest disease (42.5%) incidence of was observed in the Darjeeling district while the lowest (15%) was recorded from Alipurduar district. The maximum crop loss due to Begomovirus was 64-100% in bitter gourd, 40-80% in cucumber and 20-30% in wax gourd. 153 samples from 6 different cucurbits were collected and analysed. PCR using AV494/AC1048 primers that amplified coat protein region (~550bp) showed 74% of the samples as positive. Upon sequencing and BLAST analysis, ToLCNDV, SLCCV and BGYVV were detected. In phylogenetic analysis, the isolates clustered in three separate clades based on Begomovirus species irrespective of the hosts. Present isolates showed more closeness to Indian and Bangladesh isolates. Interpretation: The documentation of disease severity caused by Begomovirus is of extreme importance for food security of the people. Present study revealed that Begomovirus is present in all the crop field studied. The results indicated an urgent need for the management of the viruses to save crops. Key words: Begomovirus, Cucurbitaceous crops, Disease incidence, North Bengal

“…Crop selection is also an important part of disease management. As an example, bitter gourd planted adjacent to tomato plots showed susceptibility to ToLCNDV (Kiran et al 2021 ). Weeds can also act as alternative viral hosts; hence, effective and timely application of weed control, is essential.…”

Tomato leaf curl New Delhi virus (ToLCNDV), a bipartite begomovirus, was first reported to infect tomato and has recently spread rapidly as an emerging disease to Cucurbitaceae crops. To date, the virus has been reported to infect more than 11 cucurbit crops, in 16 countries and regions, causing severe yield losses. In autumn 2022, ToLCNDV was first isolated from cucurbit plants in Southeastern coastal areas of China. Phylogenetic analysis established that these isolates belong to the Asian ToLCNDV clade, and shared high nucleotide identity and closest genetic relationship with the DNA-A sequence from the Chinese tomato-infecting ToLCNDV isolate (Accession no. OP356207) and the tomato New Delhi ToLCNDV-Severe isolate (Accession no. HM159454). In this review, we summarize the occurrence and distribution, host range, detection and diagnosis, control strategies, and genetic resistance of ToLCNDV in the Cucurbitaceae. We then summarize pathways that could be undertaken to improve our understanding of this emerging disease, with the objective to develop ToLCNDV-resistant cucurbit cultivars.
