Long-term monoculture of a susceptible host results an increase in the numbers of microsclerotes in a paddock... Sclerotia of S. sclerotiorum germinate during cool, wet weather and either directly infect the base of plants at ground level or produce fruiting bodies in which ascospores are produced... The finding contrasts with recent work which shows that Fusarium thapsinum and F. andihazi are responsible for most cases of fusarium stalk rot in northern NSW and ...

Darling Downs' growers warned of mouse numbers.. Grain growers in Queensland's Darling Downs are being warned to monitor their crops for mouse-related damage and consider baiting, after a dramatic increase in mice being trapped by researchers... Recent monitoring in the Dawson and Callide Valleys in central Queensland shows mouse numbers are slightly up on what was seen during September, but populations are not high enough to be causing economic damage to crops or to justify the expense of baiting...

Nitrogen fertiliser costs dominate the fertilizer budgets of cereal cropping systems across the northern region... Given the lack of price signals for grain protein in sorghum, we can use a default 10% protein (1.6%N) as the target at which crop yields are not limited by N availability... Using the information we can determine a crop nitrogen budget for our projected yield target...

Fusarium stalk rot - red internal discoloration of sorghum stalks infected by Fusarium species.. The risk of sorghum stalk rot developing in these crops is likely to be higher in 2011 crops than in other years... Plants may or may not display symptoms of fusarium stalk rot inside the stem at the time of a pre-harvest glyphosate spray, so it is difficult to determine the potential risk of lodging in these situations...

There are two series of trials that will be reported in this paper... The 2012-13 trials investigated interactions between N and sulphur at each site only the N responses will be reported ... Across the 3 seasons of trial work only one significant increase in grain yield was recorded in the 2005-07 seasons (Table 3)...

For 30 years northern growers and agronomists have relied on Group A herbicides to control wild oats in winter crops; the days are numbered for chemical control as herbicide resistance becomes more widespread across the region.. Many agronomists concerned about the Group A resistance status of wild oats will mix haloxyfop with a 'dim' herbicide [most commonly clethodim]," Mr Cook says. ".. Factor (butroxydim) was not effective as a knockdown for wild oats in chickpeas by itself or when combined with Verdict (haloxyfop); 500 millilitres/ha of Status (clethodim) or mixtures of Verdict (haloxyfop) plus Status proved the most effective combination for knockdown control of wild oats; and..

We focused on the N 2 O emissions associated with the growth of annual legume species, the subsequent breakdown of their residues, and the uptake of their residual nitrogen by a following wheat crop... Results from the project ranged from 0.08% to 0.59% using fluxes calculated by a non-linear interpretation of gas concentration data, and slightly less using a simpler linear regression approach... The losses measured at this time were comparable with those measured under similar conditions in winter, but where there was twice the rate of fertiliser N applied, the potential for N 2 O losses appears to be much higher in the summer period...
