• Error in Figure

Figure 2 was incorrect in the original publication [1]. Bars indicating disease incidence and disease severity of the treatments “400 cm² Cu + PP” and “600 cm² Cu + PP” were interchanged in Figure 2C–F. Consequently, the average values presented in Figure 2A,B for treatments “400 cm² Cu + PP” and “600 cm² Cu + PP” were incorrect. The corrected Figure 2 is shown below.

• Changes in the text due to correction of Figure 2

Due to above mentioned mistake in Figure 2A–F, several sentences in the results section of the publication had to be revised.

On page 3, the sentence “The effect of Cuprozin progress^® in leaves was also greatly increased, leading to a decrease in disease incidence from 48% (disease severity 9%) to 21% (disease severity 1%).” was changed to “The effect of Cuprozin progress^® in leaves was also greatly increased, leading to a decrease in disease incidence from 48% (disease severity 9%) to 17% (disease severity 1%).”. Furthermore, the sentence “In the Cuprozin progress^® treatment, disease incidence was reduced from 73% (50% disease severity) to 63% (38% disease severity) after the addition of PP.” was changed to “In the Cuprozin progress^® treatment, disease incidence was reduced from 73% (50% disease severity) to 59% (34% disease severity) after the addition of PP.”.

On page 5, “Significant differences in leaves were measured for the Cuprozin progress^® treatment where PP reduced the disease incidence in leaves from 54% (7% disease severity) to 30% (3% disease severity). Considering the berries, significant differences were only observed in disease severity between the Cuprozin progress^® (57%; incidence 91%) and the Cuprozin progress^® plus PP (42%; incidence 79%) treatments.” was changed to “Significant differences in leaves were measured for the Cuprozin progress^® treatment where PP reduced the disease incidence in leaves from 54% (7% disease severity) to 18% (1% disease severity). Considering the berries, significant differences were only observed in disease severity between the Cuprozin progress^® (57%; incidence 91%) and the Cuprozin progress^® plus PP (35%; incidence 75%) treatments.”. Furthermore, the sentence “Considering the berries, significant differences were only observed in disease severity between the Cuprozin progress^® (13%; incidence 29%) and the Cuprozin progress^® plus PP treatments (5%; incidence 14%).” was revised to “Considering the berries, significant differences were only observed in disease severity between the Cuprozin progress^® (13%; incidence 29%) and the Cuprozin progress^® plus PP treatments (2%; incidence 8%).”.

The authors apologize for any inconvenience caused by the mistakes listed and state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
