Abstract:
The fungicidal effectiveness of Zn-carbamate and copper compounds and their effects on yield and quality composition of autumn-sown beets were investigated under field conditions in a subtropical area. The two kinds of compounds - at their specific optimal treatment combinations - were equally effective in their fungicidal action and in leaf preservation. Weekly applications were required in the warmer part of the growing season for optimal results; however, during the cooler, earlier period triweekly applications were sufficient. Sprinkler pre-irrigation was essential for effective control by the fungicide-treatments. Zn-carbamate significantly exceeded the two copper compounds in sucrose storage (by 1395 kg/ha). This was the result of a less phytotoxic - respiration enhancement - effect. Beaurdice, a metallic Cu-compound, exerted the most detrimental effect. The optimal treatment for sucrose storage increased: (a) the total sucrose by 5170 kg up to 18,430 kg/ha, (b) the daily net storage rate of sucrose by 311.4%, and (c) sucrose/m3 of water by 610-710 g. The effective treatments considerably improved the technological value of the beet by: (a) increasing the juice purity by 4.7% to 91.7%, (b) decreasing the sol. ash and sol. N ratios and (c) maintaining the sucrose concentration at the same, or slightly higher, level throughout the entire experimental season. It was shown that the Cu-ions restricted the sol. ash concentration in the beet by interfering with the uptake of the mineral elements or by enhancing their incorporation. © 1969 Dr. W.
