After two weeks of growth, phytomass of perennial rye-grass control plants was 8.9 mg; that of plants in the substrate containing 5 g/kg of NaCl--7.5 mg; in the substrate containing 5 g/kg of Safecote--8.6 mg; and in the substrate contaminated with the mixture of 5 g/kg NaCl/Safecote--7.1 mg.
A significant difference in phytomass of perennial rye-grass in the substrate containing 5 g/kg NaCl and the control substrate, i.e.
Just as in the case of perennial rye-grass, phytomass of common meadow-grass in the substrate contaminated only with Safecote was bigger than that of control plants (Fig.
After the 2nd week, perennial rye-grass had the longest above-ground part compared to plants of the other 2 species, i.e.
Compared to the control substrate, the height of the above-ground part of perennial rye-grass in the substrate containing 10 g/kg of Safecote, differed by 1.9 times (Fig.
El trigo, el rye-grass y el sorgo forrajero son cultivos que tradicionalmente ocupan menores niveles de productividad economica por hectarea que el nivel promedio regional.
But research at five sites over the last two years found no evidence of a spring flush of Italian rye-grass in winter cereals.
"We never saw any indication of a spring flush for rye-grass" says Dr Moss.
"We have seen fields where it is hard to find any rye-grass plants during the winter, but by June rye-grass heads are all too evident.
The practical consequences of the research, says Dr Moss, is that delayed autumn sowing has the potential to greatly reduce rye-grass infestations, provided that all emerged rye-grass plants are effectively destroyed with glyphosate pre-drilling.
Among the most effective pre-and post-emergence herbicides for rye-grass control in winter wheat, Dr Moss highlights prosulfocarb or flufenacet + pendimethalin and pinoxaden or mesosulfuron + iodosulfuron respectively.
``Also, catching rye-grass while it's still small means it's more susceptible to herbicides,'' he added.
