The stubble management decisions each of these growers made in 2010-2011 were unique to the individual and were influenced by the combination of experiences, cropping systems, agronomic and logistic challenges, and commitment to full stubble retention... The value of grazing crop stubbles to farm profitability was overestimated by the ME value of the intake the value of grazing crops cannot be predicted using energy intake from stubble... Finally the burning of stubbles also contributed to weed 26Australian Glyphosate Sustainability Working Group, Australian Herbicide Resistance Institute (2013), 9 Oct 2013...

Grain storage entomologists are closely monitoring resistance of insects to the fumigant phosphine and are advising growers and grain handlers to review their control practices... The frequency of resistance of grain insects to phosphine fumigant has steadily increased in all species since the mid-1990s... Scientists lead a national resistance monitoring program which provides information on the presence of and trends in resistance to phosphine and assists grain handlers by providing information on managing resistance and control options...

Capsicum chlorosis virus causes mottling and dark (necrotic) spots to develop on leaves, internodes are reduced in length, terminal growing points wilt and die.. Affected plants set few kernels and those which do set are small and of poor quality... Severely affected plants are stunted and may die, leaving gaps in rows...

Microplitis is the main vector of ascovirus and so plays a key role in increasing the percentage of caterpillars affected by this disease... High levels of ascovirus may lead to a decline in Microplitis wasp populations... small pale caterpillars in unusually exposed situations (e.g. on a leaf) that look as though they have been feeding in the same place for some time, making a window in the leaf, are probably infected with ascovirus because infected caterpillars can take a long time to die, ascovirus infection in the population can show up in crop scouting data over a series of checks as a number of small caterpillars (shorter than 8 mm) in the crop, with very few medium-large caterpillars coming through...
