Market prices, management costs, and time between crop inspection and pest control should all factor into deciding the need for taking action control a pest population. The ‘Economic Injury Level’ (EIL) is reached when the cost of pest control
Evaluating the logistical and economic feasibility of close-kin mark-recapture (CKMR) as a method to estimate Snapper biomass.
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
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.
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
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
