Influence of potato seed coating with entomopathogenic and mycoparasitic fungi on the yield and quality of potato tubers
 SOBOLÍK, Martin
Quality seed plays an important role in potato cultivation. Only recognised and certified seed potatoes should be used for planting. The health of the seed potatoes is therefore an important parameter. In the bachelor thesis, the effect of seedling coated with the entomopathogenic fungus Metarhizium brunneum and the mycoparasitic fungusTrichoderma virens on yield-forming parameters and the health status of the crop and subsequently harvested tubers was investigated. Both beneficial fungal species M. brunneum and T. virens had a positive effect on the growth and development of potato plant. In particular, the mycoparasitic fungus T. virens positively affected growth parameters in plants. Plants from seedlings coated with M. brunneum produced largerer and heavier tubers in compare to the control and T. virens variants. During the vegetation, the M. brunneum variant had statistically the lowest number of larvae and adults of the Leptinotarsa decemlineata. From the data, it was found that the highest actual yield was achieved with the T. virens variant and the theoretical yield with the M. brunneum variant. The BP results suggest that biological methods of plant protection by using of beneficial fungi for coating seeds can be used as an Potato Integrated Pest Management.
