The use and search for new pesticides ensuring high and stable yields is one of the
topical issues in winter wheat growing. The aim of the study was to develop theoretical
foundations and farming practices for highly productive winter wheat through the use of
pesticides of different groups in the southern forest-steppe of the Republic of Bashkortostan. An
experiment (2016–2019) with 4 main blocks was conducted to determine the optimal combination
of pesticides in cultivation of winter wheat. The pesticides were used at the tillering ((ZGS) 25)
and heading stages ((ZGS) 59) of wheat growth. The experiment was replicated 4 times. The
study results show that pesticides used to treat winter wheat increased grain yield and improved
grain quality characteristics. The best results were reached in the block where treatment included
Melafen plant growth promoter combined with the insecticide, herbicide and fungicide at
different stages of winter wheat growth. The pesticides used in the experiment confirmed their
efficiency. On the whole, the block of variants that used seed treatment produced a yield of
3.33–6.37 t ha-1
. The new plant growth promoter Melafen worked well in the experiments on
winter wheat, especially in combination with pesticides in different variations. It produced the
highest grain yield (6.36–7.41 t ha-1
). All experiment variants demonstrated positive economic
efficiency. The study results may be useful in developing winter wheat cultivation practices
aimed at increasing yields and improving grain quality.
