Several viruses and phytoplasmas (which have characteristics in common with both viruses and bacteria) infect strawberries, causing a wide range of symptoms that result in poor vigour and low yield.
Many viruses and phytoplasmas affect strawberries, either singly or in combination. These may lead to strange appearances such as green petals, crinkling and yellow spotting and vein banding of the leaves. Worse still, stunting, poor growth and loss of yield.
Those mentioned here all occur in the UK. However, a number of other strawberry viruses exist elsewhere.
These are very variable. Two of the most frequently encountered are commonly known as 'yellow edge' and 'crinkle' and are caused by the combination of viruses listed below;
In strawberries the symptoms are very variable and complex. Many viruses are involved and they can act to produce symptoms which vary according to the virus species involved, the relative proportions of each, the environmental conditions and the response of the particular host variety. However, in practical terms the most important effect is the loss of vigour and yield caused by some viruses and virus combinations, which can render the crop worthless.
Resistance: Cultivars vary in the degree of resistance they show to each virus, but none are widely resistant to the extent they can be recommended on this basis.
None available. The insecticides currently available to gardeners are non-persistent and will not provide sufficient control of the aphid vectors to prevent virus spread.
Viruses are minute parasitic entities consisting only of a nucleic acid core and a protein coat. They cannot reproduce except in the cells of the host plant, where they 'hijack' the cell's synthetic mechanisms to produce more virus particles, causing a variety of symptoms in the process.
Viruses require a vector organism to transmit them to new hosts;
The host ranges of some of these viruses, for example Arabis mosaic virus and Tobacco streak virus, are very wide and many plants can act as sources of infection. Some of the others are restricted to strawberries (including wild strawberries) and close relatives such as raspberry.
