Faba bean aphid (FBA, Megoura crassicauda) was first noted in Australia on broad beans (Vicia faba L. cv. Coles Early Dwarf) in October 2016 in a Sydney suburb, (Hales et al., 2017). FBA was then recorded in September 2017 at two faba bean trial sites: NSW DPI Tamworth Agricultural Institute (TAI) and Liverpool Plains Field Station Breeza (LPFS Breeza). These… Read more »
As the summer cropping season winds down, there are some key observations in pulse crops made by leading consultants from New South Wales’s Northern Rivers and Queensland’s Hervey Bay regions that haven’t been covered in recent Beatsheet articles. 1: Indoxacarb failures linked to poor coverage The high Helicoverpa pressure encountered this summer resulted in many indoxacarb (e.g. Steward®) sprays being… Read more »
With a range of pest outbreaks recently (including fall armyworm), and the issuing of several new permits in Australia, there has been some confusion as to whether pulse crop references on spray labels and permits in Australia include soybeans. The good news is that the answer is yes it certainly does! Soybeans are listed by the APVMA under Crop Group… Read more »
Update (20 April): There are reports that cluster caterpillars are also switching from leaf to pod feeding in maturing crops in the Mackay region, with a report of 5-10 larvae per square metre in many crops. Growers and consultants in all coastal regions are urged to check their crops for late season cluster caterpillars. Reports have just come to hand… Read more »
Several growers and agronomists across southern Queensland have reported extensive damage to their mungbean crops due to Fusarium wilt this season. Large areas of affected paddocks have plants that are wilted or dead, resulting in significant yield losses. The results of DAF annual disease surveys over the last five years have found that the disease is most common in crops… Read more »
Since early March 2020, soybean growers in the Burdekin have seen significant damage to their crops. Close inspection of crops found many with soybean stem fly damage as well as leaf spots, and stem and pod lesions. Severely affected plants have suffered complete and rapid leaf defoliation. In many crops, plants did not collapse until the late pod-fill stage, when… Read more »
Leafhoppers (also known as jassids) and seedling thrips are extremely abundant in Central Queensland this summer. The vegetable leafhoppers (Austroascra viridigrisea) are very much an ‘in your eye’ pest, with swarms of the small (3mm) bright green critters flying up when disturbed in-crop. In contrast, the cotton seedling or cereal thrips (Thrips tabaci) are hiding out of sight, down in… Read more »
Observations from recent Pulse Check field days in CQ Bean podborer (Maruca vitrata) and beet webworm (Spoladea recurvalis) are on the move in Central Queensland (CQ) mungbean crops. While both species may also be active in other mungbean regions, bean podborer is most likely to occur in coastal (e.g. the Burdekin) and subcoastal (Biloela, Kingaroy) regions. Bean podborer is a… Read more »
Rhyparida sp. (swarming leaf beetles) have been reported in some Burdekin soybean crops. While the risk of outbreaks has declined as leaves dry off, growers and consultants are reminded to keep a lookout for this sporadic but sometimes very damaging pest. Monolepta sp. (redshouldered leaf beetles) have also been observed in some crops. What to look for Dead leaves are… Read more »
In 2019, many of the faba bean crops have growths on pods. There has been much debate over the years about the cause/s of the lumps seen on the pods of faba beans; with some attributing it to thrips, or more recently to green mirid feeding. The growths are called oedema or intumescences, and are caused when the uptake of… Read more »
