Biological activity of post-emergent herbicides and their mixtures in blue lupine crops

Abstract

In the article a literary review on blue lupine sensitivity (Lupinus angustifolius L.) to the known assortment of post-emergent herbicides is stated. The results of search researches on post-emergent herbicides and their mixtures selection in the crop cv Pershatsvet and Mirtan are shown. It is determined that of main economic importance will be the herbicides of growth (mitron, SC (metamithron, 700 g/l), biphor, EC (desmedipham, 80 g/ lo+phenmedipham, 80 g/l), combined action herbicides (growth and soil – tapyr , AC (imazetapyr, 100 g/l) and tank mixtures based on them : tapyr, AC (0,5 l/ha +biphor, EC (1,5 l/ha; biphor, EC (1,5 l/ha) + mitron, SC (1,5 l/ha\); tapyr AC (0,5 l/ha) + mitron ,SC (0,5 l/ha) and tapyr, AC (0,5 l/ha) + mitron, SC (2,0 l/ha) applied at 2–4 leaves of the crop and early periods of weeds vegetation. The selection of post-emergent herbicides and their mixtures will depend on type of weed infestation and the direction of crops use.
