Catalogue: Broadacre Field Crops DAFF QLD
Although not often immediately thought of when 'crop pest' is mentioned, vertebrate animals (birds, mice, pigs, rabbits, wild dogs and kangaroos) can be a major problem in certain field cropping situations, with the potential to cause major damage to crops or property... Whether an animal becomes a pest can also be influenced by environmental conditions, for example drought can force animals into cropping areas or excellent seasonal conditions can promote breeding cycles... Native animals can become pests of crops or pose a threat to humans...

Emergency funding to address canola virus.. The Grains Research and Development Corporation (GRDC) has announced an emergency funding package of $315,000 in response to a significant outbreak of beet western yellows virus (BWYV) in canola crops in the southern region... GRDC Managing Director, John Harvey , says that in the early stages of the outbreak, initial identification of BWYV as well as testing of GPA populations for insecticide resistance was undertaken with support from existing GRDC investments...

The ability of canola to compensate for early aphid damage supports the increased use of natural enemies to control aphid outbreaks.. "Canola has an excellent capacity to compensate for crop damage, meaning current spray thresholds of around 10 per cent infestation of racemes (flower clusters) may be more stringent than necessary," says Dr Paul Grundy, senior research scientist at the Queensland Department of Agriculture and Fisheries... While the physical damage inflicted during these experiments is different to an actual aphid infestation, the results suggest that canola has an excellent capacity to compensate for crop damage...

03 5441 6176 03 5444 4299 admin@orm.com.au CAUTION: RESEARCH ON UNREGISTERED PESTICIDE USE Any research with unregistered pesticides or of unregistered products reported in this document does not constitute a recommendation for that particular use by the authors, the authors' organisations or the management committee... In summary, it could be argued that none of the currently available preemergence herbicides have the required stability in efficacy to become viable alternatives to postemergence group A or imidazolinone herbicides... Overall, 2012 seasonal conditions tended to favour early and mid flowering and maturing varieties...

Advice concerning the significance and control of the more common pests, or potential pests, of these crops is presented... Value of the crop (high value crops cannot sustain too much damage as a small loss in yield or quality could mean a large financial loss), the cost of the spray and its application and the likely yield or quality benefit gained from control... Crop monitoring Ongoing monitoring of crops and surrounding vegetation is essential to determine the presence of both pests and predators, and when, if any, intervention is required to keep pests at an acceptable level or, if feasible, boost predator numbers by introducing them into the system...

Search for answers continues as frost bites in 2012.. Significant grain crop losses caused by frost in 2012, confirmed at harvest time, add to the sense of urgency to seek solutions to this issue - a major concern for most Western Australian grain growers... The scale of losses caused by frost is a prime reason for frost being a major priority for the Grains Research and Development Corporation (GRDC), which is funding different areas of frost research, development and extension (RD&E)...
