Influence of fungicide rate (mean of fungicide products - four site mean) Stem rust control assessed over the four trial sites revealed that using high rates was essential for the control of the disease, even if the fungicide had been applied prophylactically (before infection was visible in the crop)... Influence of cultivar resistance and fungicide application (Prosaro ) on yield and stem rust severity measured on the flag sheath 18 days after fungicide application at early dough (GS82) and assessed at mid dough - physiological maturity (GS85-90) - Bairnsdale, Gippsland, Victoria, 2010... The yield potential for the crop with no nitrogen applied is estimated at GS30 from the results of numerous of trials conducted in that region where NDVI at GS30 is divided by the number of growing degree days (GDD) greater than 0 C since planting, referred to as the INSEY units (in season estimate of yield)...

For information and descriptions of recommended, commercially available varieties, growers are referred to the variety guides produced annually by Cotton Seed Distributors Ltd... Once purchased, a grower can maintain seed of a variety with Plant Breeder's Rights (PBR) protection... The area of cotton planted under irrigation should be determined by: the ability to complete an irrigation cycle every 7-10 days during peak flowering of the crop the total amount of water available, as moisture stress has a large effect on yield...

The project was established to provide advice to breeders on how to improve the adaptability of crops in the high rainfall zone (HRZ) of southern Australia so that yields could be lifted closer to potential... Information from the project needs to be extended to growers to provide guidance as to the likely impacts of different management strategies on the germplasm currently available... 2. Better understand crop growth and development of existing germplasm in the HRZ Field experiments were conducted to provide information relating to how current commercial germplasm (wheat, barley, canola and pulses) captured resources and the efficiency with which these crops converted these resources to biomass and grain...

Sunflowers are attacked by a number of insect pests at various stages of crop development... Damage both adults and larvae attack sunflower larvae feed on decaying vegetable and crop residues in the soil they also feed on newly germinating seed and the growing points of seedlings which results in patchy stands damage is most common in early-planted crops where crop residue has become scarce during summer, adults may damage young plants by surface feeding or cutting of the plant at or near soil level damage by both larvae and adults may necessitate replanting... If crops require spraying , best results are achieved before heads turn down to the ground...

At Dubbo, from June to November, 318 mm of rain fell on 52 days with 34 days >1.0mm, compared with a long-term average of 282 mm on 43 days (34 days >1.0mm)... Monitor the crops 2-3weeks after each rain event from emergence onwards and spray if Ascochyta is detected in the crop or is found in the district on any variety... (GMs also take into account other production costs estimated at $300/ha; chickpea price $450/t)..

Image of adult lucerne crownborer, showing orange to grey-brown colour and long antennae.. Minor pests of lucerne in northern Australia, Zygrita diva occurs frequently and Corrhenes stigmatica infrequently in Queensland lucerne... Proximity to lucerne increases the risk of early infestation and earlier pupation and girdling, leading to plant death...
