Biological preparations for tomato protection against seed infection under storage of genetic collection

The main cause of the tomato seeds death is considered fungi infection such as: Alternaria, Fusarium, Mucor, Penicillium [4]. The use of chemical preparations against phytopathogens is known to contribute to the reduction of field germination and inhibition of growth processes of agricultural crops [3]. Some of them have a negative effect on a plant even at the genetic level, which is not acceptable when maintaining and studying mutant collections. When storing private work collections, the choice of disinfectants must be carefully considered. The use of biological fungicides is the modern alternative. The purpose of the research is to study the biological efficacy of pre-sowing treatment of tomato seeds of the mutant form Mo 347 with biological preparations BFTIM KS-2, G and BSka-3, G against Alternaria and to determine their influence on the sowing qualities. The research was carried out in 2017-2018 under the laboratory conditions of FSBSI ARRIBPP, Krasnodar. Research material: BFTIM KS-2, G (Bacillus amyloliquefaciens KS-2 (VKPM-11141)) and BSka-3, G (Trichoderma viride 256 (VKPM B-3481); Pseudomonas koreensis Ap33 (VKPM B-3481); Bacillus subtilis 17 (Bacillus acidocaldarius) (VKPM B-5250), Bradyrhizobium japonicum 614a), Mo 347 (d) seeds. As a result of the study, it was established that the greatest biological efficacy in seed treatment against Alternaria was in the variant with the use of the biological preparation BFTIM KS- 2, F - 94.6%, in BSka-3, G was 32.4% lower. It should be noted that BSKA-3, G being bio-fertilizer with fungicidal properties, has a stimulating effect on root growth. It was also established that when using biopreparations BFTIM KS-2, G and BSka-3, G germination intensity and seed germination energy were higher than in control by 34.2-21.9% and 35.0-23.0%, respectively.
