EFFICIENCY OF CHEMICAL FUNGICIDES AGAINST LEAF TAN SPOT OF WHEAT

abstract 1121508011 issue 112 pp. 153 – 162 30.10.2015 ru 1581
In recent years leaf tan spot had dominated into pathogenic complex of wheat in southern Russia. The causative agent of this disease is hemibiotrophic ascomycete Pyrenophora tritici-repentis (Died.) Drechsler; imperfect state of Drechslera triticirepentis (Died) Shoem. It causes two different symptoms in susceptible wheat varieties: chlorosis and necrosis. Under epiphytotic disease progression crop losses can achieve 65%. One of the most important elements of phytosanitary control of wheat cenosis is scientifically relevant chemical fungicides application. Biological efficiency of some fungicides against Pyrenophora tritici-repentis has been estimated. Research was conducted on the experimental ground of FSBSI ARRIBPP on the variety susceptible to the pathogen – Krasnodarskaya 99. Preparations were tested one time at leaf-tube formation (Z37) phase or two times: at leaf-tube formation (Z37) and start of heading (Z51) stages. Double treatment was more effective than a single one. Fungicides “Amistar extra” and “Prozaro” have got the high biological efficiency – 80,7 and 83,7%, consequently, and longer protective period (up to 40 days) in comparison to every tested fungicides

EKOBENTOKORM - NATURAL SORBENTS

abstract 0831209054 issue 83 pp. 776 – 785 30.11.2012 ru 1572
Poultry farming is characterized by a relatively low cost of production, so it is more cost-effective compared with other sectors of animal husbandry. However, the feed of plant and animal origin used in the poultry industry does not always correspond to the requirements of biological safety and are subject to damage by fungi producing mycotoxins, causing extensive economic damage. Therefore, to improve the performance of the cultivation of chickens broilers was used natural sorbent - ekobentokorm (from the local cheap raw materials - bentonite clay), which is not only a source of macro - and microelements, but also with adsorptive activity in respect to mycotoxins, endotoxins, salts of heavy metals and pathogenic microflora, improves digestion and metabolism
