6 pp. / The Dietary Guidelines for Americans recommend 2 to 3 cups of vegetables daily for adults. The USDA reports that more than half of our vegetable intake comes from potatoes and tomatoes, whereas only 10% comes from bright, colorful vegetables, including carrots. This article focuses on many ways to enjoy carrots, introducing different types of dishes that utilize carrots and methods of preserving them for later consumption. The nutritional value and health benefits of carrots are also explained.

The effect of interrupted leaf wetness (IWP) and %RH on infection by Cercospora carotae (Pass.) Solh. was studied by inoculating carrot leaves (Daucus carota var sativa DC. L.) and subjecting the plants to different IWP treatment, continuous leaf wetness (CWP) and to different combinations of %RH and temperature with and without an initial wet period of 6 hr. IWP significantly reduced infection as compared to CWP. Infection was optimal under leaf wetness and decreased with decrease in percent RH. The effect of temperature and duration of moist period on sporulation of C. carotae was studied on carrot plants under leaf wetness, 96%RH, and 96%RH with an initial 12 hr of leaf wetness. For all types of moisture conditions, sporulation increased with the increase in temperature up to the optimum (28$ sp circ$C) and then declined. Logistic and polynomial models were used to describe the effect of temperature and time on sporulation under these moisture conditions. The incubation period of Cercospora carotae was studied in the field. First lesions were observed 6 to 8 days after inoculation and new lesions appeared until the 10th to 14th day. The beginning, mean, and end of incubation period was modelled as a function of mean daily temperature and mean daily RH $ ge$ 90%. A model describing lesion appearance as a function of time was developed using a logistic function (R$ sp2$ = 0.84). A prediction model containing series of equations that described mathematically the interaction among predicted inoculum, infection and sporulation equivalents for the environment was developed and validated. In general, the model predicted adequately Cercospora blight progress. A weather-based forecasting system was developed to time the first fungicide spray to manage Cercospora blight of carrot based on the accumulation of critical number of disease severity units.

The fungal plant pathogen <I>Sclerotinia sclerotiorum</I> (Lib.) de Bary is responsible for disease in a wide range of crops throughout the world. Sclerotinia disease, or cottony soft rot, in carrot (<I>Daucus carota</I> L.) crops is generally a post-harvest problem during storage. Research has, therefore, focused in this area. However, little attention has been paid to foliar and root crown damage caused by <I>S. sclerotiorum</I> during crop development, a problem prevalent in crops in the North East of Scotland. The conventional method for controlling <I>S. sclerotiorum</I> in the developing crop is fungicide application, which often gives only partial control. There is no recognised effective control method in organic systems. This study investigated a diverse array of potential control methods, involving combinations of cultural, biological, environmental and forecasting methods, all lying within the confines of organic regulations. A number of germination characteristics of the <I>S. sclerotiorum</I> sub-population in question were studied. Steam sterilisation of soil was then investigated as a possible replacement for methyl bromide fumigation. Steam was shown to have potential control properties regarding sclerotia of <I>S. sclerotiorum</I>, if combined with manipulation of soil matric potential. Commercially available biological control agents, soil amendments and conventional fungicides were compared in the search for the most effective control for Sclerotinia. The product found to be most effective in this group, and acceptable for use in organic systems, <I>Coniothyrium minitans,</I> was further investigated in combination with organically produced compost and readily soluble nitrogen fertiliser. <I>C. minitans</I> provided a level of control in both instances. The application of high levels of nitrogen fertiliser encouraged severe infections, as did excessive irrigation of crops. A number of methods and practices were unsuccessfully applied, or suggested by the studies, that can reduce the incidence of disease caused by <I>S. sclerotiorum</I> in carrot crops in North East Scotland, and are acceptable to both conventional and organic systems.
