Winter triticale protection against the dominant pests under conditions of belarus

Abstract

The article provides with the improved species composition of phytophages, the structure of dominance and their harmfulness in winter triticale crops. The foci of agrocenoses colonization by such pests as turnip moth (Agrotis segetum Den. & Schiff.) and wheat opomyza (Opomyza florum F.) are indicated. For the first time in 2016, the invasion of a new pest for Belarus – corn ground beetle (Zabrus tenebrioides Goeze) is registered. The effectiveness of products with different mechanisms of action and active ingredients against a complex of pests which have been mass developed in 2015–2016 has been evaluated. Pre-sowing seed treatment by the insecticidal action preparations reduced the damage of winter triticale by wireworms for 80,8–91,0%, cereal flies for 62,2–79,2%, corn ground beetle larvae for 70,6–91,2%. During triticale vegetation period under field experiment conditions, the most effective was a contact-systemic action preparation Eforiya, EC, which reduced cereal leaf beetles number up to 96,4%.
