Abstract
The routine and excessive use of fungicides to control fungal diseases in the field, without perceiving the risks and vulnerability they cause, must be considered in modern agriculture. The objective was to evaluate the effectiveness of some fungicides for the control of scald (Rhynchosporium secalis) in wheat, evaluating their impact on yield. A completely randomized design was used, with five treatments and four repetitions. The fungicides applied by spraying were: picoxystrobin + cyproconazole, tebuconazole and pyraclostrobin. The incidence, severity, and biological effectiveness to control scald, finding the percentages according to formulas in each treatment. Number of seeds and the average weight of the grain per spike were evaluated. At four months, the average number of seeds per spike and the average weight of the grain were evaluated. The scald affected the culture from the early stages and with high inoculum pressure. The highest biological effectiveness was obtained with tebuconazole 500 mL ha-1, followed by (picoxystrobin + cyproconazole) 400 mL ha-1. Both in the average number of seeds per spike and in the average grain weight, the best result was when pyractrostrobin was applied, followed by picoxystrobin + cyproconazole. tebuconazole only favored the average grain weight. The results showed that use of fungicides was convenient to reduce the decrease in wheat production, always mixed with an adjuvant.
