Lowering the herbicide doses with their frequent application positively influences the economy of sugar beet growing

Practically mostly common used dicots weed controlling comes from 3 postemergent applications. But this scheme is very often modified (in relation to actual weather conditions which strongly influences the dynamics of sugarbeet growth). One of the new ways in weed controlling system is the application of lower, but more frequently applicated doses. For verifying of the influence of the lower, frequent doses on yield and technological quality of sugar beet and verifying of the effectivity on weeds we set Lip field trials during the years 2005-2007. Unambiguously was proved that there were achieved better yield parameters with the lower, frequent doses. We managed to prove that lower, frequent doses shows out comparable or even better efficiency on weeds than conventional weed controlling system. Achieved results refers to possibility of better economical results of sugar beet growing with using the lower frequent doses. From our results we can evaluate experimental variants with lower, frequent doses very positively and consider them as one of the ways to higher yields and ways to the lowering of negative impacts on our environment.
