Evaluation the Efficiency of Newly Combined Herbicide Pyroxsulam and Galaxifen-methyl in Winter Wheat (Triticum aestivum L.)

Globally, wheat production is essential for food security as it is an essential staple food crop for a huge population. However, there are different biotic and abiotic factors affected the productivity of wheat. One of the essential competitors of wheat crop are weeds. Wheat is infested by both annual and perennial dicotyledonous weeds. The main purpose of this study is to evaluate the efficiency of the new combined herbicide Tarzec WG based on pyroxsulam and galaxifen-methyl + safener cloquintocet-mexyl for protecting winter wheat from the weeds.

The field experiment was conducted during 2019 and 2020. The experimental treatments consisted of Tarzec two application rates: 19 g/ha and 22 g/ha. Reference standards were applied, Pallas 45 (22 g/ha of pyroxsulam).

Results revealed that the greatest advantage of the combined herbicide Tarzec WG over the single-component agent Pallas 45 OD was attained through the inhibition degree against weeds in both the seasons of experiment. Unfortunately, these compelling advantages of combined agent over the single-component one was not identified with respect to Cerastiumnemorale, Avenafatua and Alopecurus myosuroides. Tarzec WG herbicide was not phytotoxic to the plants of the winter wheat.
