Abstract
When studying the effectiveness of using promising herbicides on crops of corn hybrids in the central zone of the Krasnodar Territory, it was found that corn crops are predominantly contaminated with dicotyledonous weeds such as Theophrastus rope, upturned acorn grass, ragwort, white pigweed, self-seeded poppy, and shepherd’s purse. Cereal (monocot) weeds are represented by blue bristle grass, green bristle grass and chicken millet. Perennial weeds include by field bindweed. The most effective herbicide is Adengo in the 1–2 leaf stage, giving a yield increase of 56.1 c/ha. At the same time, corn hybrids in the mid-early group yielded 91.5 c/ha and those in the mid-ripening group 77.1 c/ha. To obtain a corn yield of 100 c/ha, it is necessary to apply the herbicide Adengo (0.5 l/ha) at the stage of 1–2 leaves in the technology of cultivation of its hybrids DKS3969, DKS3 and DKS3789
