Kernels contaminated with aflatoxin bring a reduced price and, in cases of very high levels, may be downgraded to oil quality... High soil temperatures and drought during flowering and podfill are the major causes of aflatoxin contamination... Leaving peanuts in the windrow to dry to 13% moisture increases the risk of aflatoxin because of the chance of rain re-wetting the crop...

Cereal disease authorities, supported by the Grains Research and Development Corporation (GRDC), say fungicides have an important role to play in disease control but they should be seen as just one component of an overall management strategy... "And while fungicides can be very effective in offering protection from diseases, they must be used judiciously and as part of a multi-faceted management strategy which should also include c ontrolling the green bridge for cereal rusts, attention to the potential risk of stubble-borne leaf disease when deciding on crop rotations, and avoiding susceptible varieties... The Fact Sheet provides information on identifying and understanding fungal diseases, cereal disease diagnosis, fungicide modes of action, foliar fungicide timing, tips for optimal fungicide efficacy, the economics of using fungicides, fungicide resistance, and stewardship...

Ascovirus-infected larvae are small, pale and can look as though they have been grazing in one place, leaving small 'windows' in the leaf State of Queensland.. Some predators found commonly in crops will not feed on helicoverpa at all and some may only feed on certain stages (for example, larvae of a particular size, or only eggs)... Natural enemies will rarely eradicate all eggs or larvae, but may reduce infestations to below economic threshold if predators and parasitoids are not disrupted by broad-spectrum insecticides...

Scientists in Perth have found a novel way to control two costly and damaging fungal diseases of wheat - but in a way that will not involve any new chemicals or added costs to growers... The breakthrough hinges on the discovery that these fungi are only infectious if they can awaken obsolete disease-resistance genes that lurk in wheat's vast genome... Researchers have found no yield penalty associated with disease insensitivity (arising from the elimination of Tsn1 from cultivars) as there can be with varieties bred with disease resistance, which is why some growers still risk growing susceptible varieties...

Adult plant resistance (APR) to cereal fungal diseases is an important trait for grain growers to consider when choosing varieties to sow... APR can complement a fungicide strategy by protecting, from diseases such as rust, those parts of the plant most responsible for yield... Adult plant resistance is a useful trait to consider in variety selection, and understanding how it works can make fungicide application decisions easier...
