In the years 2000–2003 under Polish climatic conditions early blight occurred at different level of incidence on over 90.6% of surveyed fields. Time of disease appearance in different regions was closely related to climatic conditions. On average, early blight appeared on potato plants 59.3 days after planting, earlier than late blight. In the years 2001–2003, efficacy of six selected fungicides in early blight control was examined in field conditions. Experiments carried out in the Department of Potato Protection and Seed Science of Plant Breedingand Acclimatization Institute. Field trials located in two sites – at Bonin and Stare Olesno revealed much slower development of early blight on these fields where chemical protection was applied as compared to untreated control. Efficacy of plant protection program carried out in Bonin over three years varied from 40% to 63.9%. Effectiveness of selected products was higher in Stare Olesno at higher infection pressure, and ranged from 49.8% to 66.6%. However, efficiency of chemical protection in early blight suppressing is not as satisfactory as in late blight control. In field experiments good control of early blight resulted in tuber yield increase. In Bonin yield increase varied from 5.5 to 24.2% and in Stare Olesno from 12.2 to 34.4%.

Effectiveness of insecticide protection of very early edible potato cultivars against potato beetle was assessed in the years 2005-2006. The research used Prestige 290 FS, Regent 200 SC and Spruzit 04 preparations, as well as Beauveria bassiana entomopathogenic fungus spore suspension. The selection of preparations for potato beetle control significantly diversified the amount and structure of potato tuber yield. Average total tuber yield on the control, without insecticide protection, was 30.3 t∙ha⁻¹, whereas on the treatments where Spruzit 04E C and B. bassiana spore suspension were applied the yield was on the level of 36 t∙ha⁻¹, whereas potatoes protected by chemical preparations Regent 200 SC and Prestige 290 FS produced the largest yields, respectively on the level 41.0 and 41.8 t∙ha⁻¹. Potato beetle control in potato cultivation contributed to an increase in average tuber weight and the share of big tuber fractions in the yield. A significant rise in the marketable tuber fraction was registered only on treatments protected with B. bassiana spore suspension and by Prestige 290 FS preparation.
