The time between GS30 (end of tillering, start of stem elongation) and GS50 (end of booting, flag leaf is out, start of head emergence) depends on weather, growing region and varieties. A rough indication for wheat and barley is shown in table 2,
Monitoring biological factors affecting juvenile Snapper in SA’s gulfs and studying the relationships between recruitment and potential environmental influences.
Investigating possible changes in length and age, growth rates, and maturity size of Snapper in SA to inform stock assessment models.
The action threshold developed for Russian wheat aphid (RWA) is ‘dynamic’. This means that yield potential, market value of the crop, and cost of control are factored into each season’s calculation. At GS30 determine the RWA Action Threshold
Using the active acoustic methodology developed in WA to estimate the biomass of Snapper aggregations in SA’s gulfs.
Russian wheat aphid (Diuraphis noxia). Since its discovery in South Australia in 2016, Russian wheat aphid (RWA) has been found widespread in cereal-growing regions of South Australia, Victoria, New South Wales, and Tasmania. Given the very dry
Black field crickets. Black field crickets (Teleogryllus commodus) have been observed in higher than usual numbers in cropping and pasture paddocks around parts of South Australia this autumn. Large numbers have been reported in the South-East
Why SA can't ignore fall armyworm. The fall armyworm (Spodoptera frugiperda), an invasive pest native to the Americas, has been a growing concern for Australian agriculture in recent years. Fall armyworm, known for its rapid spread and big appetite,
Using the 'degree-day' model to stay ahead of Etiella. The lucerne seed web moth, also known as ‘Etiella’, may appear irregularly but is a serious pest that can cause significant damage to lentil and lucerne crops. They can also impact other
Look out for these emergence pests. Many of our management practices for cropping have changed dramatically over the last 20 years. Reduced tillage and increased stubble retention has resulted in changes to soil moisture retention, groundcover and
