Abstract

We studied the efficacy of seed treatment with a variety of fungicides for control of root rot of wheat in different soil types. The effectiveness of various doses of the preparation on the basis of thiram (TMTD and TMTD-plus) and triazole containing Dividend Star, SC has been compared under the conditions of the Southern Urals in typical soils of the region (dark chestnut, southern chernozem, common chernozem). It is revealed that the effectiveness of thiram containing preparations in moderate doses (2.0–2.5 l/t for TMTD-plus and 3.0 l/t for TMTD) is higher on the dark-chestnut soils than on Chernozem. The biological efficiency of the Dividend Star does not depend on the type of soil. We compared the five pesticides with active substances from different chemical classes: Celest Top (thiamethoxam + difenoconazole + fludioxonil), Scenic Combi (clothianidin + fluoxastrobin + prothioconazole + tebuconazole), Maxim (fludioxonil), TMTD-plus (thiram), Kinto Duo (triticonazole + prochloraz) and Dividend Star (difenoconazole + cyproconazole) at the different tillage technologies under the non black soil region conditions. The effectiveness of all preparations decreases significantly at the no-till technology compared to the plowing. Most effective in plowing were Kinto Duo, Celest Top and TMTD-plus, and in zero-till – Celest Top and Scenic Combi.
