    SUNFLOWER PROTECTION AGAINST SPREAD DISEASES IN THE WESTERN FOREST-STEPPE OF UKRAINE
    (CEP USM, 2024-10-07) Andriychuk, Tetyana; Skoreiko, Alla; Kuvshynov, Alexander
    The results of fungicide usage BAS 762 02 F against spread sunflower diseases: septoria leaf spot of sunflower (Septoria helianthiEll. et Kell.) and alternaria (Alternaria helianthi (Hansf.) Tubaki & Nishih.) in the western Forest-steppe of Ukraine. The best rates of usage for preparations' input according to the studies results during 2021–2022. The fungicide highest efficiency against septoria leaf spot observed in the scope 0.8–1.0 l/ha. The preparation's technical efficiency consisted of 78.8–81.4%. The fungicide BAS 762 02 F usage against alternaria reduced the sunflower's plant disease development on 3.7–6.9 times at preparation's consumption rate 0,6– 1,0 l/ha in comparison with control. The preparation's technical efficiency consisted of 72.7 – 85.5%.

    Performanţa hibrizilor de floarea-soarelui în diverse condiţii de mediu ale Republicii Moldova
    (CEP USM, 2024-10-07) Duca, Maria; Port, Angela; Clapco, Steliana; Mutu, Ana; Burcovschi, Ion
    The rising frequency of suboptimal temperatures and early droughts hinder the genetic potential realization of sunflower hybrids, posing challenges in achieving stable harvest yields. It was analyzed the harvest of 21 hybrids grown in 5 localities of the Republic of Moldova in correlation with the annual amount of precipitation from 2015-2020. The variation of the yield according to the genotype of the studied hybrids and the impact of the conditions in the growing environment were highlighted.
