Carrot red leaf virus

Abstract Internal necrosis of carrot has been observed in UK carrots for at least 10 years, and has been anecdotally linked to virus infection. Publication types Research Support, Non-U.

In Australia, a hymenopterous parasite of C. There has since been a dramatic decrease in numbers of C. However, this appears to have been an over-statement because it was subsequently reported from the Australian Capital Territory Waterhouse, In California, overwintering carrot crops are the main source of infection for spring-sown crops Watson and Falk, , and it is recommended to plant at a distance from overwintering crops, or if this is not practicable to grow resistant tolerant cultivars.

However, the market cannot accept a preponderance of such cultivars, and the use of insecticides may also be necessary. The disease was responsible for serious losses in Australia in the s and s, when it caused the virtual abandonment of early carrot production in the area around Melbourne, Victoria, and was the principal factor limiting carrot seed production Stubbs, It has since declined in importance in Australia Stubbs et al.

The disease also caused serious crop failures in England in the s and s Watson, ; Watson and Serjeant, ; Cock and Dixon, Watson and Serjeant investigated the effect of motley dwarf disease on carrot in field experiments.

Naturally infected crops suffered more because of the additional damage caused by aphid infestation, Cavariella aegopodii being a serious pest in its own right. External factsheets English.
