Vulpia Hair Grass
In New Zealand three species of Vulpia (Vulpia spp) are found and being very difficult to identify they are collectively known as vulpia hair grass (VHG) or silver grass, rat-tail or squirrel-tailed fescue. Left uncontrolled VHG is a very aggressive weed leading to very serious yield losses and reduced seed quality through contamination. When small VFG has very thin upright and hair-like leaves, hence its name, and it grows in a tufty manner. Germination generally takes place at the same time as the crop. Later when it comes into ear it develops the long silvery panicles which give it the other common names.
