ABSTRACT: In recent years "redness" has increasingly appeared in strawberry plants with leaves taking on a reddish color. No causal agent has been associated with plants. Since strawberries presented problems due to the incidence of nematodes, the purpose of this study was to look at the relationship between production, resistance to the Meloidogyne hapla nematode and the "redness" symptom in strawberry cultivars. Two experiments were performed, both with the 'Camino Real', 'Festival', 'Oso Grande', 'Albion' and 'Camarosa' cultivars. The first experiment was performed in the field, where the following were evaluated: strawberry production, fruit quality, macro and micronutrient contents in fruit and leaves, percentage of plant survival, incidence of nematodes, quantity of eggs in the roots and juveniles in the soil, and the incidence of Botrytis cinerea . In the second experiment, the strawberries were transplanted into pots and filled with pinus bark-based commercial substrate. Half the pots were inocculated with Meloidogyne hapla . Cultivars presented differences in fruit production and also in the incidence of "redness". Lowest performance in production was related to the high incidence of the nematode Meloidogyne hapla. 'Oso Grande' and 'Albion' presented nematode-resistant behavior. It was possible find a relationship between the incidence of the Meloidogyne hapla nematode, and the incidence of "redness" only 'Camino Real' cultivar.

The objective of this work was to evaluate three strawberry cultivars in an organic production system combined with the application of biological products via leaf for the control of Botrytis cinerea aiming at increasing fruit productivity and quality. The experimental design was randomized block, in a 5x3 factorial scheme, consisting of four products and three cultivars. The treatments consisted of the biological products Onix (Bacillus methylotrophicus), Quartz (Bacillus amyloliquefaciens), Botector (Aureobasidium pullulans), Prestop (Gliocladium catenatum) and control (water application in the plot) in combination with three strawberry cultivars (Cristal, Monterey and Pircinque). Through the results it was possible to observe the superiority of the cultivar Cristal in the total fruit production when compared to the cultivars Monterey and Pircinque. The biological products Onix, Quartz and Botector provided higher total strawberry production. The recommended cultivar for planting in the southern region of Minas Gerais is Pircinque due to the high levels of soluble solids and total sugars observed. The application of biological products was effective in controlling Botrytis cinerea.

Strawberry Cultivars

Botrytis cinerea, the causal agent of Botrytis fruit rot, is annually introduced into Florida strawberry fields by infected transplants. The disease can be managed by fungicide sprays throughout the season; however, previous studies have demonstrated that several chemical classes are no longer effective owing to B. cinerea resistance. The objectives of this study were to evaluate the effectiveness of preplant fungicide-dip treatments of strawberry transplants on reducing B. cinerea colonization and to evaluate fungicide sensitivity of surviving B. cinerea isolates. Transplants of two strawberry cultivars, Winterstar ‘FL 05-107’ and ‘Florida Radiance’, were dipped in 11 different fungicides. After the plant establishment period, eight leaves per plot were collected before and 14 days after treatment to evaluate B. cinerea incidence. Isolates (n = 139) obtained from the transplants were tested for fungicide sensitivity. Plant diameter was measured 47 days after planting. All treatments, including the controls, reduced B. cinerea incidence by at least 77% compared with predip incidence. However, fungicide-resistant isolates were recovered from all treatments tested.

Nowadays the success vegetable and fruit production are unimaginable without regular nutrient management. One of the ways to supply the required nutrients in an environmentally friendly way is the application of composts, which is less widespread so far. Compost doses were applied in biological and integrated apple orchards in cooperation with the Institute of Horticultural Science in the years 2010 and 2011. Different changes were resulted by the compost treatments in the examined parameters in case of both apple varieties (Golden Delicious and Pinova). There is no clear effect of compost on the changes of ash-, total acids, Vitamin C and the sugar content until now, because the improvement of the nutritional indicators takes more time. However significant differences were observed after one year between the apple varieties. Higher ash-, total acids and sugar content were measured in case of the apple variety Pinova, while the measurements showed higher Vitamin C content in case of the variety Golden Delicious.

Abstract Certified organic farm area in Poland increased 8.5 fold during the 2003-2010 time period to 518 thousand ha, which constituted 2.8% of the arable land. The production costs and profitability of the organic fruit production of apples, strawberries, and sour cherries were evaluated and compared to conventional production of those fruits. The research was based on data from thirty-two commercial fruit farms; twenty farms with conventional production, and twelve with organic production. The main problems associated with organic production were the costs of weed control and soil cultivation. The conventional production of apples turned out to be slightly more profitable than the organic production. The organic production of sour cherries was not profitable. In the case of strawberries, it was the opposite - the organic production gave a better financial outcome than the conventional one

With the reduction in the availability of methyl bromide as a soil fumigant for Florida strawberry (Fragaria ×ananassa) culture, annual broadleaf weeds are expected to become increasingly troublesome to control. Recent studies show that along with the new fumigant systems, separate but complementary herbicide applications throughout the growing season will also be a necessity for acceptable weed control. The purpose of the study reported herein was to evaluate the impacts of multiple rates of the herbicide clopyralid on the growth and fruit production of four annual strawberry cultivars. Two greenhouse trials were conducted, evaluating the application of varying rates of clopyralid as a directed spray to well-established, mature plants of ‘Strawberry Festival’, ‘Florida Radiance’, ‘Treasure’, and Winterstar™ ‘FL 05–107’. Leaf production, leaf malformation, and marketable yield were evaluated to determine negative effects because of the physiological herbicidal effects, phytotoxic herbicidal effects, or both of clopyralid. Results from these studies showed that when clopyralid was applied at the maximum labeled rate of 3 oz/acre, less than 12% leaf malformation was observed among all cultivars, and marketable yield exhibited a linear increase as the rate of clopyralid increased, possibly due to a reduction in canopy coverage leading to more effective pollination.
