An evaporation basin is a natural salt lake or engineered earth structure designed to store and evaporate saline water.

In July 2017,  information days were held to advise agribusiness on supporting sheep farmers through the dry season.

African swine fever (ASF) is a highly contagious virus that causes an often fatal disease in pigs and wild boar.

This interactive map – produced by the Department of Primary Industries and Regional Development (DPIRD) – allows you to explore south-west Western Australian regional groundwater trends, local gro

Use the canola seeding rate calculator for the easiest way to calculate the seeding rate.

Wild radish (Raphanus raphanistrum) is highly competitive in crops and can cause a yield loss of 10-90%.

Pasture manipulation is the application of herbicides for grass control early in the growing season (autumn or early winter).

It is often the preferred option for grass control.

The viability of annual ryegrass seed can be reduced substantially by desiccation, pre-harvest spraying or swathing of canola depending on the product and timing.

This paper reports on a three year series (2014-2016) of trials to provide WA grain growers experimental field evidence of the effect of crown rot on barley and wheat variety yields.

Strong fires will cause significant damage to bush on farms and may devastate revegetation areas.

Herbicide resistance is the inherited ability of an individual plant to survive a herbicide application that would kill a normal population of the same species.

Some types of saline land in Western Australia have potential for sequestering significant amounts of carbon.

It is not always easy to identify the degree of dispersion or sodicity in soils. The choice of suitable management depends on knowing the soil sodicity and whether dispersion is a problem.

We use land-use planning to ensure that land and water resources are available for agriculture and food businesses to expand and grow.

PestFax is an interactive reporting service, providing risk alerts, current information and advice on pests and diseases threatening crops and pastures throughout the grain belt of Western Australi
