Type: conference-paper
Abstract: Diseases are one of the main factors limiting the reception of high sunflower yields. The use of biological preparations for plant protection will allow to fight diseases successfully and improve the products quality. The article presents the results of research on the efficiency of application of biopreparations under the trademarks of BSka-3 with active ingredient Trichoderma viride, Pseudomonas koreensis, Bacillus subtilis and BFTIM with active ingredient Bacillus amyloliquefaciens against sunflower diseases. We conducted the experiments in 2018-2019 on the fields of the “Berezanskoye” farm in Korenovsky district of the Krasnodar region. We established that biofungicides effectively suppressed seed infection. In 2018-2019, dry rot of heads (Rhizopus spp.), bacterioses (Xanthomonas spp., Pseudomonas spp.) and Verticillium wilt (Verticillium dahliae Kleb.) had the highest prevalence in the sunflower sowing: 49.75 %, 42.0 % and 47.0 %, respectively. The schemes of BSka-3 D + BFTIM I + BFTIM K and BSka-3 A + BFTIM B + BFTIM B showed the best biological efficacy against Rhizopus spp.: 37 and 38 %, respectively. The schemes of BSka-3 D + BFTIM I + BFTIM K and BSka-3 G + BFTIM Zh + BFTIM Z were the most effective against the bacterioses: 54 and 51 %, respectively; the standard and variant of BSka-3 B + BFTIM V + BFTIM G showed 32 and 31 % of efficiency, respectively, against Verticillium wilt. The schemes of BSka-3 A + BFTIM B + BFTIM B (2.65 t/ha) and BSka-3 + BFTMI I + BFTMI K (2.61 t/ha) showed the best economic effectiveness.
