Economic efficiency of plant fungicide protection of five resistant against Cercospora leaf spot sugar beet varieties were tested in two factor experiment on plots in 2013-2014. Sugar beet varieties (Finezja, Gallant, Jagusia, Milton and Pikador) and chemical protection against Cercospora leaf spot (protected and unprotected plots as a control) were factor of experiment. The index of leaf infection by Cercospora beticola and root yield were estimated at the late vegetation time. Economic effectiveness of fungicide protection against C. beticola were calculated using cost coverage ratio (Wpk) and rough profitability index E1 and E2. Protection of resistant sugar beet varieties in low pathogen pressure condition resulted in significant reduction of infection index and root yield increase. Yield increase compensated cost of fungicide protection in case of two among five varieties.

Monitoring of the two-spotted spider mite occurrence were conducted on sugar beet crop in southern districts of Kuyavian-Pomeranian Voivodeship. Observations were carried out in 2014, from June to September. A total of 662 plantations were assessed. Monitoring results showed that 60% of sugar beet plantations were settled by two-spotted spider mite, 26,3 % of them severely.

One field trail was carried out in Żydowo in 2015-2016. The cultivation profitability of the five sugar beet varieties tolerant to pest compered to average profitability of three varieties without tolerance was assessed. The number of living eggs and larvae of Heterodera schachtii in field soil was below the harm threshold. The results showed that the cultivation of new tolerant sugar beet varieties on a bed of low pest pressure compared to varieties without tolerance was highly profitable. It was found that the additional cost incurred for the purchase of tolerant varieties in 2015 turned from 4.0 to 7.4 times depending on the variety, whereas in 2016 from 8.4 to 35.3 times, respectively.
