EVALUATION OF THE EFFICIENCY OF FEMIDA, OD HERBICIDE APPLIED TO WINTER WHEAT IN SPRING

Abstract

The paper presents the results of the research on biological and economic efficiency of the new herbicide Femida, OD (2,4 D-acid, 320 g/l of 2-ethylhexyl ester + 4.2 g/l of chlorsulfuron) produced by Schelkovo Agrohim, Ltd., Russia. It’s established that with protection of winter wheat at the tillering stage in spring the reduction of infestation with annual and perennial weeds amounts to more than 85 %, in particular, blind weed, lamb’s-quarters, field scorpion grass, dead beans – 100 %; wild camomile – 85,4–100 %, scratch grass – 78,3–100 %, blue bottle flower – 95,5–100 %, field violet – 65,7–80.7 %, field sow thistle – 91,7–100 %.
