The present study aims to identify combinations of active substances for the complex control of pathogens and pests on eggplant crops in the field. The experiments were conducted between 2016 - 2017, in field conditions, using the variety of eggplant Luiza and the following experimental variants: V 1 - Acrobat MZ 69 WG 0.2% + Mospilan 20 SG 0.04%; V 2 - Acrobat MZ 69 WG 0.2% + Vertimec 1.8 EC 0.1%; V 3 - Acrobat MZ 69 WG 0.2% + Laser 240 SC 0.05%; V 4 - Melody Compact 49 WG 0.2% + Mospilan 20 SG 0.04%; V 5 - Melody Compact 49 WG 0.2% + Vertimec 1.8 EC 0.1%; V 6 - Melody Compact 49 WG 0.2% + Laser 240 SC 0.05%; V 7 - Ortiva Top 0.1% + Mospilan 20 SG 0.04%; V 8 - Ortiva Top 0.1% + Vertimec 1.8 EC 0.1%; V 9 - Ortiva Top 0.1% + Laser 240 SC 0.05%; V 10 - untreated control. The average efficacy of the treatment variants experienced in 2016 and 2017 varied between 83.2% (V4) and 85.0% (V8) depending on the combinations of products pathogens and pests control. Analyzing the yields obtained (34.6 -44.0 t / ha in 2016 and 33.5 - 43.1 t / ha in 2017), compared to the untreated control variant (30.4 t / ha in 2016 and 31.1 t / ha in 2017), it is found that the yield differences obtained in addition to the untreated control variants were in all cases, very significant.

The mycelial growth rate of 4 strains of Pleurotus eryngii was first studied on different culture media -MEA, PDA and WEA (wheat extract agar). In the next experiment, we checked the mycelial growth on the same medium but at 3 different pHs. MEA medium ensured the highest growth rates for all the strains under test, followed by PDA. Pery-G strain showed the fastest growing rate on MEA (5.79 mm day -1 ) and PDA (3.04 mm day -1 ), respectively. Test concerning the mycelium growth on PDA at different initial pH values (5.5, 6.0, 6.5) showed the preference of our P. eryngii strains for media with a weak acid to the neutral reaction, the optimal values being 6.0. There were no big differences among mycelium growing rates of the same strain for the three pH variants.

The main purpose of the experiences organized at Research and Development Institute for Vegetable and Flower Growing Vidra was to evaluate the behavior of different cultivars of eggplants in specific soil and climate conditions of the Vidra area and to identify those with high yields, with quality fruits and tolerant to soil borne pathogens attack. In 2016, 12 cultivars of eggplants were studied: 6 non-hybrid varieties (Daniela, Luiza, Dragaica, Zaraza, Belona, Black Beauty) and 6 hybrids (Andra F1, Rebeca F1, Bibo F1, Clorinda F1, Mirabelle F1, Epic F1).The highest yield was achieved in Rebeca F1 and Luiza cultivars. The highest vitamin C content was realized at Rebeca F1, Luiza, and Zaraza cultivars. The Mirabelle F1 hybrid and Black Beauty variety presented a reduced sensitivity to Verticillium dahliae and Fusarium oxysporum f. sp. melongenae.
