Annual ryegrass (Lolium rigidum) is one of the most serious and costly weeds of annual winter cropping systems in southern Australia.
Herbicides play a vital role in integrated weed management programs.
Claying involves adding and incorporating clay-rich subsoil into water repellent topsoil to overcome the repellence.
Herbicides can be applied by a variety of means including boom sprayers, aerial spraying, misters, blanket wipers, rope wick applicators, weed seekers and back-pack sprayers.
The most accurate way to estimate the weed population of a paddock is to count the number of plants in an area of known size at a number of locations.
Silver grass is an annual grass occurring in both cropping and grazing regions across Australia. There are several species, the most common being Vulpia myuros and V. bromoides.
Barley grass is a common name for Hordeum glaucum and H. leporinum.
