To evaluate the effectiveness of different fungicide strategies for the management of blackspot disease infection in field pea to determine the most appropriate strategy for the southern low rainfall zone.

Annual ryegrass at high density reduces crop yield. However, this weed is highly sensitive to crop competition. Initial control with pre-emergent herbicides combined with high seeding rates in cereal crops may be sufficient to control this species.

The trial aims to investigate pre-emergent herbicides and high density crop seeding in a wheat crop.

To evaluate the response of canola to low fertiliser inputs

• To compare the competitiveness of new and existing barley varieties in the presence and absence of weeds.
• To increase the competitiveness of a non-competitive variety through sowing time and nitrogen applications in the presence of weeds.

To determine if retaining canola seed leads to reduced yield, oil and financial return.

This experiment is one in a series of nitrogen experiments aimed at establishing variety responses to different nitrogen application rates and timings.

Varieties can differ in their ability to yield at various sowing dates. The same goes for their response to various rates of nitrogen and how they turn that nitrogen into yield and protein. This trial was designed to measure the influence of sowing date and nitrogen rate across six common wheat varieties.

To compare the performance of older TT canola varieties (Tanami, Cobbler, Crusher and Snapper) under normal growing conditions in the Ballidu region.

Onion weed (Asphodelus fistulosusis) is a significant pest of crops and pastures on many soil types on upper EP. Onion weed that germinates in the pasture phase often results in thick stands of large plants that require repeated herbicide application and/or cultivation to control prior to a crop phase. Cultivation prior to sowing is a widespread practice to control the weed and reduce the residues to manageable levels. However, cultivation can expose the soil to erosion.

Onion weed in pastures regularly sets seed prior to the end of the growing season, ensuring the seed bank is replenished and the weed persists in every phase of the rotation. A key strategy to reduce the impact of onion weed, and the need for cultivation, is to reduce growth and seed set in the pasture phase of the rotation. Non-selective herbicides can control actively growing onion weed plants, but pasture growth is also affected.

Previous trials by the UNFS group, MDB NRM, and PIRSA have shown the following herbicides can provide adequate control of onion weed in non-selective situations:

                    Paraquat and double knocks of paraquat

                    Glyphosate plus metsulfuron methyl mixtures (+/- paraquat second knock)

                    Glyphosate plus LVE ester 2,4- D plus metsulfuron methyl,( +/- paraquat second knock)

                    Chlorsulfuron

                    Spray Seed

                    Alliance

This trial was established to investigate herbicide control of autumn/winter germinating onion weed in the pasture phase, while maintaining the productivity of the medic pasture. This trial evaluated the herbicide control of young actively growing onion weed in a vigorous medic pasture. The herbicides, with the exception of paraquat, were chosen to minimise the impact on the medic biomass production.
