Impact of yellow leaf virus on sugarcane commercial fields

A survey of Sugarcane yellow leaf virus (SCYLV) was conducted in northern Argentina in 2015 and 2016 using tissue blot immunoassay (TBIA). Results showed plant infection rates of 2.2–86.7% in sugarcane commercial fields from different growing areas. Percentage of infected leaves varied among cultiva...

Description
Summary:A survey of Sugarcane yellow leaf virus (SCYLV) was conducted in northern Argentina in 2015 and 2016 using tissue blot immunoassay (TBIA). Results showed plant infection rates of 2.2–86.7% in sugarcane commercial fields from different growing areas. Percentage of infected leaves varied among cultivars and areas. NA 05–860 was the most infected cultivar (86.7% incidence). Virus genotypic diversity of SCYLV positive samples was analysed by reverse transcription polymerase chain reaction (RT-PCR). The virus genotype BRA-PER was found in all samples, followed by genotypes REU and CUB (36% and 8% of positive samples, respectively). The following co-infection patterns were found: BRA-PER + REU (34%); BRA-PER + CUB (6%); and the three genotypes, BRA-PER + REU + CUB (2%). Sugar content loss in cultivar LCP 85–384 infected with SCYLV was evaluated. Sugar yield reduction in SCYLV positive plants was statistically significant in dryland conditions ( p
