Welcome to a new format for NGA communication.
We hope to utilize this style of approach for future Newsletters and also Project Reports to improve both our efficiency but also timeliness of communication. The appointment of Kim Thomas (see side article) will greatly improve our ability to manage these regular communications whilst also responding to an apparently ever increasing need for technical project activity!
We would greatly appreciate any feedback (positive or negative) on this approach as we strive to make the project outcomes easier for you to access whilst also simpler for us to administer.
2011 Winter Trials Snapshots
1. ROOT-LESION NEMATODES
A site has been established in the Weemelah area to evaluate the impact of Pratylenchus thornei on the yield of a wide range of winter crop species and varieties. All varieties are being evaluated under both high and low P thornei pressure. The crop and variety impact on P thornei multiplication will also be assessed together with the combined impact of crown rot and P thornei.
2. FABA BEAN DISEASE MANAGEMENT
Two trials will be conducted in the Moree/Narrabri and Walgett areas to compare disease development and yield impact from a range of fungicide strategies. Strategies will be benchmarked against a standard mancozeb approach. Key disease targets are rust and chocolate spot.
3. BARLEY LEAF RUST
Six trials will be conducted to evaluate disease development, yield and grain quality impact from a range of fungicide strategies. Trials are expected to be conducted in commercial paddocks of Grout to limit other disease interactions. Trials will include single and multiple spray regimes.
4. HARVEST AIDS IN CANOLA
Three trials are planned to compare a range of products which will be applied ~ 3 weeks prior to harvest. Product choice, rate and water volume will be the key focus in determining whether these products have a fit to reduce shattering losses and possibly allow more direct heading.
5. HARVEST AIDS IN CEREALS
Three trials are planned to investigate product rate and water volume with aim of reducing grain quality losses due to weather damage and potentially lowering shattering losses. Intention is to conduct trials in commercial paddocks but induce weather damage under controlled conditions on samples taken from the paddock.
6. FEATHERTOP RHODES GRASS
Four trials are planned to screen a range of winter crop grass selective herbicides for activity against feathertop Rhodes grass. Trials are likely to be conducted in fallow situations on early spring germinations. A range of group A and B chemistry is being evaluated.
7. FLEABANE CONTROL IN-CROP
Four trials are planned to compare a range of in-crop herbicide approaches to assist in the management of fleabane. Growers and agronomist are keen to examine alternative programs that can help reduce the issues, cost and difficulty of controlling fleabane in the summer fallow. Three trials have already commenced with PSPE applications.
8. WATER QUALITY IMPACTS
Three trials are planned to determine the impact of water bicarbonate and hardness levels on the control of fleabane with glyphosate/ 2,4 D amine treatments. Trials will also examine the fit of ammonium sulphate to assist in improving fleabane control reliability.
9. BOTRYTIS IN CHICKPEA
Three trials are being conducted in collaboration with Dr Kevin Moore (NSW DPI). A range of seed treatments are being compared for the control of seed-borne Botrytis seedling blight. Planting seed has been sourced from paddocks badly infected with Botrytis grey mould in 2010. Exciting results have already been found.
10. CROWN ROT FOLIAR SPRAYS
Five trials are planned to complete a project commenced in 2009. Pathology results have consistently shown some promising impacts on stem browning and crown rot incidence. Plan is to gather more information on pathology, yield and grain quality to help determine whether these approaches are economic.
