Abstract

A field study was conducted in 2004 to determine the effects of different concentrations of adjuvant (CITOGATE) on the efficiency of desmedipham+ chloridazon. The experimental design was randomized complete block design with factorial arrangement of treatments, and four replication. Factors included three herbicide doses (60, 80 and 100% of recommended dose) and four adjuvant concentrations (0, 15, 25, 35, ml/100L). Different traits including yield, yield component, biomass, weed biomass, sugar beet root length, leaf dry weight and sugar concentration were studied. The Highest grain yield, biomass, root length, and leaf dry weight were related to the complete dose of herbicide plus 35ml/100L adjuvant. The highest root diameter was achieved where sugar beet was treated with 80 and 100% of the chloridazon recommended dose plus 25ml/100l adjuvant.
