Evaluation of fluopyram for the control of in sugar beet.

Fluopyram, a succinate dehydrogenase inhibitor fungicide, has shown potential in controlling and in tomato. The effectiveness of this compound for the control of in sugar beet was evaluated. In this study, laboratory, growth chamber, glasshouse, and field experiments were conducted.

Quantity and quality of food losses along the Swiss potato supply chain: Stepwise investigation and the influence of quality standards on losses.

This paper presents the results of a stepwise investigation of the quantity and quality of food losses along the Swiss potato supply chain. Quantitative data were collected from field trials, from structured interviews with wholesalers, processors and retailers, and from consumer surveys in combination with a 30-day diary study. The "Swiss trade customs for potatoes" pose the basis for the qualitative evaluation of losses.

Potential of acrylamide formation, sugars, and free asparagine in potatoes: a comparison of cultivars and farming systems.

Glucose, fructose, sucrose, free asparagine, and free glutamine were analyzed in 74 potato samples from 17 potato cultivars grown in 2002 at various locations in Switzerland and different farming systems. The potential of these potatoes for acrylamide formation was measured with a standardized heat treatment. These potentials correlated well with the product of the concentrations of reducing sugars and asparagine.
