One of the main reasons of low potato yields in Poland is plant health. Many farmers, particularly those growing potatoes for their own needs, plant the same material year by year, making the situation worse and worse. Such a procedure significantly increases the viral infections of plants. The yield obtained from such infected plants will be always low. Numerous disqualifications of seed plantations or the degradations to lower degree ranging in 1989-2001 from 14.9 to 43.1%, indicate strong threat by viruses. Seed tubers mag also be a source of bacterial and fungal origin diseases. The most dangerous are: the black leg, wet rot of tubers and common scab. Apart from production specialization the healthy seed tubers are the basis to reduce the risk of diseases. Sprout rot (Rhizoctonia solani) also decreases the yield. Extremely high threat occurs in the years of lower temperature and higher soil moisture content during germination. Potato blight (Phytophthora infestans) is a serious problem during the whole vegetation season. Losses of potato yield in Poland in the years favourable for disease development on unprotected plantations may achieve even 60-70% of potential yield. In the last years increased demand on the tubers of very high quality, both for direct consumption, and for industrial processing, resulted in higher importance of tuber peel pathogens. Silver scurf (Helminthosporium solani), occurring at various intensity, becomes more and more important in Poland. Dry rot of the tubers (Fusarium spp.) may also develop during storage. Separate problem is connected with preventing the expansion of quarantine diseases that may cause loses, both direct - lower yield, and indirect - resulting from quarantine regulations - such as field disqualification, prohibition of potato cultivation, ban of the export and local turnover. Under Polish climatic conditions the most dangerous quarantine objects are ring rot of potato (Clacibacter michiganensis subsp. sepedonicus) and potato canker (Synchytrium endobioticum).

In 2008 and 2010 Fusarium head blight (FHB) occurred sporadically and the number of ears with disease symptoms did not exceed 1%. An high increase of disease occurrence was observed at both locations in 2009. Significant differences were recorded between cultivars (1.0 to 35.0% of ears). The most susceptible cultivar to Fusarium head blightwas cultivar Tybalt followed by cultivars Partyzan, Bombona and Trappe. Different nitrogen fertilization significanty affected the disease occurrence only in case of cvs. Trappe, Nawra and Bombona.

The aim of experiments was to evaluate the occurrence of fungi on grain of winter wheat cv. Roma cultivated in four systems on the experimental fields owned by the Institute of Soil Science and Plant Cultivation. Among pathogenic species, fungi from genus Fusarium dominated. Their number was the lowest on grain harvested in organic system and the highest in integrated one. Saprotrophic species were represented mainly by Alternaria alternata, which occurred the most often in organic system. Determination of F. avenaceum, F. culmorum and F. poae with microscope was confirmed with a PCR assay. All isolates of F. culmorum and F. poae gave an amplification product of Tri 5 gene coding the possibility of trichocene production, while none of isolates of F. avenaceum

The study was conducted on 50 single-hyphe R. solani isolates from potato tubers and sprouts grown in different regions of Poland and town of Bilitt (Norway). PCR assay showed that 45 isolates had the expected amplification product which classified them into group AG 3. Five isolates, which did not reveal the presence of this product were tested with SCAR primer sets designed for identification of AG 2-1 and AG 2-2 groups. PCR assay showed one isolate belonging to the AG 2-1 group, but no amplification product was produced for group AG 2-2.

Field experiments were carried out over 2002-2004 at the Experiment Station of the University of Technology and Agriculture at Mochełek, in the vicinity of Bydgoszcz, on a very good rye complex soil. High biomass yields were recorded for all the nonpapilionaceous plants researched, grown in stubble intercrop. Upon no nitrogen fertilization, sunflower showed to be most productive. The treatments which involved a high nitrogen dose (90 kg·ha-1) oil radish yielded significantly higher that phacelia. The plant produced also significantly more post-harvest residue mass than sunflower and phacelia, and also used nitrogen applied prior-to-sowing most considerably. An increase in the dose from 0 to 90 kg of nitrogen resulted in an increase in its accumulation in the plant biomass by 74.4 kg (82.7% of the nitrogen applied), as compared with the non-fertilized treatments. Sunflower used only 49.0 kg (54.4%), while phacelia – 48.2 kg (53.6%). The nitrogen fertilization applied in the experiments significantly increased the overground plant biomass yield of the crops researched. The greatest reaction to N fertilization was demonstrated by oil radish. The dry matter yield of this plant increased by 26.5% due to the application of 45 kg·ha-1, as compared with the yield collected from unfertilized objects. Increasing the nitrogen dose from 45 to 90 kg·ha-1 resulted in an 18.4% increase in the dry matter yield of radish. The effectiveness of nitrogen fertilization of sunflower was definitely lower and was, respectively, 14.6 and 7.0%. There was observed a relatively low infection with fungal pathogens in sunflower and phacelia, much higher in radish. A significant effect of the fertilization dose on the health status of the plant roots was found. Sunflower roots were most healthy when 45 kg·ha-1 was applied, and the most heavily infected when treated with 90 kg N·ha-1. Radish fertilization with nitrogen, irrespective of the dose, increased the root infection with fungi. There was found no clear effect of the nitrogen fertilization dose on the health status of phacelia roots. The pathogenic fungi isolated from infected roots of plants grown as intercrops were dominated by Alternaria alternata, as well as Fusarium spp., especially F. solani, F. avenaceum and F. culmorum.

The experiment conducted in 2002-2004 and located on experimental fields owned by the Institute of Soil Science and Plant Cultivation determined the effect of pre-germination of organically grown six cultivars (Bard, Bila, Baszta, Wolfram, Wawrzyn, Bzura) of potato seed tubers on occurrence of common scab (Streptomyces scabies) and dry rot of tubers (Fusarium spp.). Common scab was observed each year on all examined potato cultivars, but its intensity varied. The least number of symptoms showed Wawrzyn cv., while Wolfram cv. - the highest. Pre-germination of seed tubers significantly reduced both the percentage and disease index (DI) calculated for S. scabies, with the exception for Wawrzyn and Bard cvs. Symptoms of dry rot of tubers (Fusarium spp.) were noted in higher intensity in 2004 on Bzura cv. (5.8%) and significantly more symptoms were observed on pre-germinated potato tubers.

From 1999 to 2007, in separate experiments located in Mazury, Żuławy Wiślane and Powiśle, the presence of Fusarium head blight (FHB) of wheat as dependent on the forecrop and fungicide application was studied. During the experiments, FHB occurred in different intensities. High intensity was observed in the years 1999, 2001 and 2007. In other years it was low or only at trace levels. More disease symptoms were observed on the plots after wheat than after oilseed rape. Controlled treatments, applied during the period of shoot development, only limited the presence of FHB.
