Abstract

The article investigated the effect of various fungicide preparations and their combined use with IFO PZN 3.0 l/ha on the main biometric and yield parameters of winter wheat plants. Based on the analysis, such important parameters as plant height, ear length, number of grains per ear, and grain weight per ear were studied. The obtained results showed that their combined use with IFO PZN provides higher efficiency compared to separate application of the preparations. The highest parameters were recorded for the Rauma 490 k.e. 1.25 l/ha + IFO PZN 3.0 l/ha preparation, with a plant height of 118.3 cm, ear length of 10.5 cm, number of grains per ear of 47 cm, and grain weight of 2.0 g. The AZOTE 320 SC 0.3 l/ha + IFO PZN 3.0 l/ha variant also showed high results.
