This paper reports the results of an investigation into a condition of the Cuthbert red raspberry which is quite distinct from any previously described disease. The disease, termed yellow blotch-curl, is characterized principally by a loose type of curling and pale chlorotic foliage which sometimes shows a yellow blotching and ring spot. The disease has been transmitted by patch-grafting, which indicates that it is of the virus type. It has been transmitted to Cuthbert, Viking, Latham, Herbert, Chief, and Lloyd George varieties, and different reactions have been noted and described.From these experiments it is concluded that "yellow blotch-curl" is distinct from mosaic and leaf curl.

A virus disease that occurs on red raspberry in the Okanagan Valley in British Columbia was identified as raspberry leaf curl. Under experimental conditions the virus was transmitted by the aphid Aphis idaci V. d.G. Test plants included red raspberry, Rubus idaeus L.; black raspberry, Rubus occidentalis L.; wineberry, Rubus phoenicolasius Maxim.; Rubus henryi Hemsl. & Kuntse; and the Alpine strawberry, Fragaria vesca L. The virus did not infect black raspberry and caused only transitory symptoms on Alpine strawberry. Root cuttings of red raspberry, leaf-bud cuttings of R. henryi, and seedlings of wineberry provided satisfactory indicator plants. Wineberry and R. henryi were more readily inoculated by aphids than red raspberry. Non-viruliferous aphids required a feed of at least 1 day on the virus source to acquire an infective charge. When viruliferous aphids were transferred to a series of healthy indicator plants, some plants became infected after a test access time of 20 minutes, although transmissions were increased if the time was increased to 1 hour. The virus was found to persist in viruliferous aphids for at least 11 days. Leaf curl virus was not eliminated from infected plants held at an air temperature of 37 °C for periods up to 4 weeks.

In this study, the effect of a Kenyan strain of Sweetpotato leaf curl virus (SPLCV) and its interactions with Sweetpotato feathery mottle virus (SPFMV) and Sweetpotato chlorotic stunt virus (SPCSV) on root yield was determined. Trials were performed during two seasons using varieties Kakamega and Ejumula and contrasting in their resistance to sweetpotato virus disease in a randomized complete block design with 16 treatments replicated three times. The treatments included plants graft inoculated with SPLCV, SPFMV, and SPCSV alone and in possible dual or triple combinations. Yield and yield-related parameters were evaluated at harvest. The results showed marked differences in the effect of SPLCV infection on the two varieties. Ejumula, which is highly susceptible to SPFMV and SPCSV, suffered no significant yield loss from SPLCV infection, whereas Kakamega, which is moderately resistant to SPFMV and SPCSV, suffered an average of 47% yield loss from SPLCV, despite only mild symptoms occurring in both varieties. These results highlight the variability in yield response to SPLCV between sweetpotato cultivars as well as a lack of correlation of SPLCV-related symptoms with yield reduction. In addition, they underline the lack of correlation between resistance to the RNA viruses SPCSV and SPFMV and the DNA virus SPLCV. [Formula: see text] Copyright © 2020 The Author(s).

A plant virus disease, not previously described, was obtained from the leafhopper Austroagallia torrida Evans collected from lucerne fields in Canberra. Symptoms have not been recognized in the field, but 16 species of plants from eight families developed symptoms in the glass-house.
