Lately, winter oilseed rape has become more and more grown by farmers in Romania, being a rewarding and versatile crop. Black leg (Leptosphaeria maculans) and stem rot (Sclerotinia sclerotiorum) continue to cause significant yield losses in Romania in winter oilseed rape, despite widespread use of fungicides. A series of three trials were conducted in Călărai County in 2021 to quantify the contribution of a mixture of Azoxystrobin 20% and Difenoconazole 12.5% at three different rates and of cultivar resistance. In the field, assessments were performed to conclude the frequency (F%) and intensity (I%) of the attack, in order to calculate the degree of attack (DA%). In the end, the effectiveness of the treatment scheme was calculated. Significant effectiveness and yield differences were recorded between cultivars and fungicides dose rates in the fields. Fungicides higher rates gave better control of diseases than lower ones and contributed to disease control and to yield responses to a greater extent than cultivar resistance. DA% of black leg infection was lower than of stem rot. [ABSTRACT FROM AUTHOR] |
