Science Into Practice - Studying cavity spot controls

Cavity spot is a major problem for carrot growers but development of the disease is highly dependent on environmental factors so it cannot be easily predicted before planting.

In the new HDC project FV 405 (Carrots: Control of carrot cavity spot through the use of pre-crop green manures/biofumigation) the Warwick Crop Centre research team, led by John Clarkson, is building on preliminary work by Dez Barbara where chopping and incorporation of hot varieties of mustard along with a plastic film covering were demonstrated to effectively control carrot cavity spot.

In this project, the team will investigate whether the mustards and other green manures can provide effective control in a commercial setting - even without the expensive sealing film - in order to develop a commercially viable pre-carrot "insurance policy" against the risk of cavity spot.

The project will also investigate whether hot mustards have any beneficial effects on numbers of free-living parasitic nematodes and/or on Sclerotinia sclerotiorum sclerotia. It is hoped that a sustainable disease-control method can be developed that is acceptable for both conventional and organic production systems.

A summary of the project can be found on the HDC website at www.hdc.org.uk.

What do fruit and vegetable growers hope for from a renationalised farming policy?

Defra's "Health & Harmony" consultation paper, which closed for responses this week, has given growers and their representative bodies a chance to shape the largest reformulation of farming and land-use policy in nearly half a century.

Cost factors, ventilation benefits and the ability to fit new advanced films are some of the reasons behind the popularity of these structures, says Sally Drury.
