In 2013 pod infection was observed in all monitored regions of Victoria... Pod infection will result in seed infection.&nbsp; Infected seeds may die and shrivel and/or cause pod shatter, reducing yield... Even if flower petals are infected, dry conditions or cool wet conditions during petal fall will prevent stem infection development.<strong> <br></strong></li> </ol><h3>Research findings in 2013</h3> <p>In 2013 sclerotinia was observed in all canola producing states it was more severe in North Eastern Victoria, NSW and WA...

For much of the last two decades, they have been managed in-crop, predominantly using Group A herbicides... In recent years it has become clear that herbicide resistant wild oats are becoming a key threat to a sustainable northern farming system... 1. No significant rate response was obtained by increasing the rate of Triflur Xcel or Avadex Xtra in the mixture..

Grain prices at 2007/08 levels provide an opportunity to increase crop intensity and production with a reduced financial risk and higher financial reward cost control and monitoring remains the key to business success... Higher cost of inputs for fertilizer, sprays and fuel will increase the financial risk... Decision Support Tools help farm business mangers to determine their financial risk and exposure...

The previous project ANU00014 led to the identification of wheat genes induced by mechanical stress on roots such as occurs during soil drying or the encounter by root tips of compact soil... The aim of the project is to determine, directly in wheat, the phenotypes induced by down- and up-regulation of target genes and their alleles, obtained through genetic manipulation... The project will contribute knowledge and molecular markers relating to the genetic determinants of the root phenotypes induced by mechanical stress in dry and hard soils, such as reduced growth, altered branching, root functionality and capacity to sustain aerial growth while saving scarce or difficult to access water...

PLANTING CHICKPEAS in rows spaced wider than the conventional 19 cm has its advantages... While not reducing the incidence of fungal diseases like Ascochyta, wide row spacings do allow growers to spray over the rows only - and this reduces overall spraying costs... The proportion of the plot area being covered was calculated and the chemical rate adjusted ...

Plants lose most of their water through stomata, the same valves that also regulate the entry of carbon dioxide into leaves and photosynthetic organs... Although plants tend to coordinate stomatal conductance and photosynthetic capacity, significant genetic variation in transpiration efficiency, the ratio of photosynthesis to transpiration, has been demonstrated in many species, including wheat... Elucidating the genetic determinants of this variation is necessary to the design of genotypes tailored to different rainfall patterns and better able to optimise the use of water for maximum growth, or survival and completion of the development cycle...

Stripe rust management Prevention is generally best - Grains Research &amp; Development Corporation </title> <meta name="GRDC.Tags" value=""> <meta name="Keywords" value="Wheat, stripe rust, leaf disease, fungicides, yield, 0, Stripe rust management Prevention is generally best"> <meta name="Description" value=" Richard Daniel, Northern Grower Alliance (NGA) &bull; Early or preventative foliar sprays, applied from GS32 onwards on moderately susceptible varieties, have provided the best returns in northern trials over the last three years &bull; High grain prices and low fungicide costs mean breakeven yield benefits required are often only 1-2% &bull; Application can be the major cost of treatment &bull.. Fungicide recommendations for stripe rust management have been based on disease threshold levels on specific leaves... This was a sensible strategy given high fungicide costs, low grain prices and the need for higher levels of yield benefit to generate economic returns...
