Control of Soil-Borne Disease of Soybean

Soil-borne diseases are a significant cause of reduction in crop yield. Alternative management of soils can enhance the natural disease-controlling organisms in the soil. This study explores the impact of alternative production methods on a primary soybean disease, charcoal rot, caused by the fungus Macrophomina phaseolina. Treatments that could potentially enhance or control the disease were implemented, and soil tests were conducted for nutrient and disease presence. Manure increased the nutrient levels in the soil, as expected, but did not impact the disease control. Solarization increased the temperature within the plots, and increased the number of colony forming units of M. phaseolina. Environmental conditions during the 2022 growing season were much hotter and drier than normal, leading to reduced soybean yields

Early Soybean Planting in a Water-Limited Growing Season

Appropriate management, with a longer growing season during reproductive growth stages, can increase biomass and yield in soybean. Our objective was to determine the impact of three planting dates, two seed populations, and three maturity groups on grain yield in southeast Kansas. However, due to the severe drought in 2022, with a total rainfall of 18.84 inches during the soybean growing season (55% lower than the 10-yr average), the growing conditions were very limited, resulting in an average yield of 1.7 bu/a

Fungicide Efficacy on Fusarium Head Blight of Hard Red Winter Wheat in Parsons, KS

In 2022, a field experiment was conducted to investigate the efficacy of fungicide programs on Fusarium head blight (FHB) and deoxynivalenol (DON) levels. Fungicide treatments were evaluated in plots of the hard red winter wheat cultivar ‘KanMark’ inoculated with Fusarium graminearum in Parsons, KS. Treatments consisted of a single application of Prosaro, Caramba, Miravis Ace, Prosaro Pro, or Sphaerex at early anthesis (Feekes 10.5.1), or dual application of Miravis Ace at early anthesis followed by (fb) Prosaro Pro, Sphaerex, or Folicur at 4 days after early anthesis. All fungicide programs numerically reduced FHB visual symptoms and resulted in increased yield compared to the untreated check, although differences were not statistically significant in all cases. The double application treatments (Miravis Ace fb Prosaro Pro, and Miravis Ace fb Spharex) resulted in the highest increase in test weight. Miravis Ace applied at early anthesis fb Prosaro Pro applied at 4 days after early anthesis resulted in the lowest DON levels (79% less than the untreated check)

Latin American consumption of major food groups: Results from the ELANS study

Background The Latin American (LA) region is still facing an ongoing epidemiological transition and shows a complex public health scenario regarding non-communicable diseases (NCDs). A healthy diet and consumption of specific food groups may decrease the risk of NCDs, however there is a lack of dietary intake data in LA countries. Objective Provide updated data on the dietary intake of key science-based selected food groups related to NCDs risk in LA countries. Design ELANS (Latin American Study of Nutrition and Health) is a multicenter cross-sectional study assessing food consumption from an urban sample between15 to 65 years old from 8 LA countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela). Two 24-HR were obtained from 9, 218 individuals. The daily intake of 10 food groups related to NCDs risk (fruits; vegetables; legumes/beans; nuts and seeds; whole grains products; fish and seafood; yogurt; red meat; processed meats; sugar-sweetened beverages (ready-to-drink and homemade)) were assessed and compared to global recommendations. Results Only 7.2% of the overall sample reached WHO's recommendation for fruits and vegetables consumption (400 grams per day). Regarding the dietary patterns related to a reduced risk of NCDs, among the overall sample legumes and fruits were the food groups with closer intake to the recommendation, although much lower than expected (13.1% and 11.5%, respectively). Less than 3.5% of the sample met the optimal consumption level of vegetables, nuts, whole grains, fish and yogurt. Largest country-dependent differences in average daily consumption were found for legumes, nuts, fish, and yogurt. Mean consumption of SSB showed large differences between countries. Conclusion Diet intake quality is deficient for nutrient-dense food groups, suggesting a higher risk for NCDs in the urban LA region in upcoming decades. These data provide relevant and up-to-date information to take urgent public health actions to improve consumption of critically foods in order to prevent NCDs. Copyright
