    During our research we have made a fermented solution and infusion of two plants, namely nettle and bear garlic. The experiments took place in the exhibition garden at the Horticultural Faculty of Kecskemét College. Kápia paprika was the objective of the experiment. We have collected leaf samples from the experiment units and measured the growth quantity. The nettle and bear garlic extracts have a good effect on the growth quantity and the condition of plants. The injury of Helicoverpa Armigera could have been diagnosed only in the plants of the control group, however this has not occured in the treated groups. According to our research results we recommend using these plant extracts in practice for the purpose of biological control and nutrient supply.

    Examination of resistance to Sclerotinia stalk and head rot in sunflower (Helianthus annuus L.) hybrids
    (2015-06-02) Vojnich, Viktor; Hüvely, Attila; Palkovics, András
    Nowadays, phytopathogenic fungi cause the most serious yield loss in open field cultures, and sunflower (Helianthus annuus) is no exception to this phenomenon. Sclerotinia stalk and head rot (Sclerotinia sclerotiorum) is present in the whole area of Hungary, and can cause serious financial loss. In our experiment, sunflower hybrids were tested for resistance to Sclerotinia sclerotiorum infection. 16 sunflower hybrids were examined at the Experimental Breeding Site in Jászboldogháza. Pesticide treatment and also nutrient replacement were applied on the sunflower fields.
