The influence of fertilizers and plant protection products for the mycotoxins, pesticides and heavy metals accumulation in the grain of winter wheat variety Antonina grown at the experimental station of the Kuban University was investigated. In the resulted grain there were no traces of the fungicide “Фалькон”, insecticide “Эйфория “ and herbicide “Секатор турбо” used in the cultivation. The content of T-2 toxin is almost at the level of MPC 0.1 mg / kg in all variants of the experiment that indicates the fungal infection invading from the soil. The content of Mn, Cu, Zn, Pb, Cd, Co, Ni, Cr in grain did not exceed MAC for adult nutrition.

Goal. Assessment of the influence of growing leguminous perennial herbs on the intensity of heavy metals accumulation in winter wheat as in a subsequent crop rotation. Methods. Field, laboratory atomic absorption method, mathematical and statistical processing. Results. cultivation of winter wheat after precursors of Medicago sativa I., Trifolium pratense L., Onobrychis arenaria Kit., Melilotus albus L., Lotus corniculatus L. or Galéga orientalis Lam. leads to a decrease in the content of lead by 1.8-2.5 times, cadmium – by 1.7–2.6 times, copper - 2.2–4.6 times and zinc - 1.6–1.9 times compared to winter wheat after corn precursor on silage. To obtain winter wheat with a minimum lead and copper content, the optimal precursor is Onobrychis arenaria Kit., with a minimum cadmium content - Galéga orientalis Lam. precursor, with a minimum copper and zinc content - the Trifolium precursorpratense L. The lowest influence on the reduction of heavy metals accumulation in winter wheat grain is caused by the precursor Lotus corniculatus L. Thanks to the use of leguminous perennial herbs as a precursor to winter wheat, it is possible to reduce the accumulation coefficient of heavy metals by 1.1-2.9 times compared with the corn precursor on silage. The lowest accumulation coefficient of the studied heavy metals was observed after the precursor of Medicago sativa I. Conclusion. Leguminous perennial herbs - Medicago sativa I., Trifolium pratense L., Onobrychis arenaria Kit., Melilotus albus L., Lotus corniculatus L. and Galega orientalis Lam. promote optimization of soil condition by increasing the content of humus, minerals nutrients, optimization of soil acidity. As a result, they reduce the accumulation of heavy metals (lead, cadmium, copper, and zinc) in winter wheat as the next crop in crop rotation and contribute to the reduction of accumulation coefficient of heavy metals in winter wheat.

In the period from 2012 to 2015 on Kalym winter wheat variety plants there were carried out field tests of the liquid culture of B. subtilis BZR 336g and BZR 517 strains isolated from natural sources that exhibit antifungal activity against phytopathogenic fungi Fusarium graminearum, F. culmorum, Microdochium nivale and Pyrenophora tritici-repentis, and are also able to have a positive effect on the growth and development of plants. Pre-sowing seed treatment and two preventive treatments during the growing season of the plants were carried out with the liquid culture of the strains. Comparison variants - treatment with water (control), with chemical (Raxil, KS; Alto Super, KS) and with biological (Fitosporin-M, L) standards. Biological efficacy against the complex of fusarium root rots was noted in the shooting stage of winter wheat and during ripening, and in some years reached 22.8 % for B. subtilis BZR 336g strain and 17.2 % for B. subtilis BZR 517 strain. In variants with presowing seed treatment and treatment of vegetative winter wheat plants with B. subtilis BZR 336g strain for three years of field trials the yield was from 5.0 to 7.4 t / ha, and when treated with B. subtilis BZR 517 strain - from 4.2 to 7.6 t / ha. The maximum additional yield was obtained in 2013 - a reliable yield increase was 1.6 t / ha for B. subtilis BZR 336g strain and 0.8 t / ha for B. subtilis BZR 517 strain. The ability of liquid cultures of the studied strains to protect winter wheat against harmful diseases at the same level and above the biological and chemical standards will help to expand the range of microbial biological products in the segment of the Russian market of environmentally friendly plant protection products.

The heavy metal concentration (e.g., Mn, Zn, Pb and Ni) were determined in soft tissues and shells of freshwater mussels (Lamellidens marginalis) at the various sites of Dhanmondi lake, Dhaka, Bangladesh between the period April, 2010 and March 2011. The heavy metal concentrations in shells and soft tissues of freshwater mussels were tended to vary significantly among sampling points and seasons in Dhanmondi Lake. Distribution of heavy metals in shell and soft tissue of Lamellidens marginalis followed the order Mn>Zn>Pb>Ni, respectively. According to the t-test, level of manganese, zinc and lead under investigation between shell and tissue showed statistically significant differences [Mn: t=-11.387; df=16; P=0.000; Zn: t=-2.590; df=16; P=0.020 and Pb: t=-2.8679; df=16; P=0.011].
