Effectiveness and selectivity of sugar maize cultivars after mezotrione+rimsulfuron application.

摘要

In 2005-2007 field experiments were carried out on weed control and reaction of 10 sugar maize varieties - Basin, Challenger, Jubilee, Golda, GSS 5022, Helena, Shimmer, Spirit, Sweet Trophy and Sweet Tasty to mixture mezotrione+rimsulfuron. The mixture was applied in recommended doses at the growth stage 3-4 leaves. On check plots the main species of weeds were: Brassica napus, Chenopodium album, Viola arvensis, Polygonum convolvulus and Echinochloa crus-galli. The mixture gave full control of B. napus and E. crus-galli and the least useful was V. arvensis and Ch. album. The mixture was selective for varieties.
