Abstract: The relevance of the study was to establish a link between low temperatures, seed treaters and plants, and to develop technological measures to increase plant resistance to possible spring frosts. In accordance with this, the purpose of the study was to determine the effect of fungicidal seed treaters on the ability of corn seedlings to counteract low-temperature stress. Both laboratory and field methods were used to conduct studies to determine the reaction of corn plants to fungicidal seed treaters (Vencedor, Avicenna, Maxim XL, Bastion, and Fever) at low temperatures. Under optimal laboratory temperatures, treatment with all preparations did not negatively affect the germination energy and laboratory germination of seeds of the Onio corn hybrid and line B 831. It was found that despite the same high results of laboratory germination of corn seeds, field germination on the provocative low-temperature background of early sowing dates as a result of the use of different seed treaters was very different. In years with varying moisture levels and low temperatures, high germination rates were observed when using the fungicide seed dressings Vencedor, Avicenna, and Maxim XL (at a level of 70-90%). Significantly lower results of field germination were obtained when using bastion and fever preparations – 45-60%. Thus, in the conditions of early sowing, and considering the risk of returning spring cold weather, it is more expedient to use Vencedor, Avicenna, and Maxim XL seed treaters. The results of this study indicate the need for pesticide originators and research institutions to conduct a more detailed study of the reaction of plants to drugs under various weather conditions and are of practical importance in production for more effective use of drugs
