The vegetable looper damages flowers and pods of azuki beans, mungbeans and navy beans, as well as soybean leaves... Larvae are primarily foliage feeders in soybeans but will attack the flowers and developing pods in azuki beans, mungbeans and navy beans... In azuki beans, mungbeans and navy beans, where flowers and pods are attacked, the threshold is set at three looper larvae per square metre...

Peanut diseases are discussed in more detail throughout this research update this section has been kept brief... As the crop does not mature evenly it can be difficult to determine exactly when to dig... Monitoring of commercial crops suggest that crop oils are ineffective in managing high SLW populations (Fig. 2)...

The only available management options for other major pests, particularly podsucking bugs and podborers, have the potential to derail IPM because they are highly disruptive to beneficial insects... Additional major IPM issues are the ever present resistance threat to the new generation pesticides targeting Helicoverpa armigera, the eventual likely deregistration by the APVMA of dimethoate (the only effective mirid and aphicide in grain crops), and the ongoing need for multi-pest IPM to reduce the risk of silverleaf whitefly (SLW)... Ongoing RD&E is clearly needed to address these issues and to continually improve and maximise the adoption of IPM throughout the GRDC Northern Region...

CSD Grains" general manager, Joe Erbacher, says it is a way of showing customers that the Australian soybean industry takes identity preservation seriously... The Japanese market is very discerning and since the camera has been installed, sales within Japan have increased, which is obviously good for us," David says...

The silverleaf whitefly (SLW - Bemisia tabaci B-biotype) has developed into an important problem pest in cotton... SLW secretes a sticky honeydew that can contaminate cotton lint once there are open bolls in the crop (Figure 1)... In summary, the key take-home messages for managing SLW in soybeans are (a) adopt the go soft early spray strategy, (b) observe mirid thresholds, and (c) avoid late plantings in regions with a history of high late season SLW pressure...

The crops should be well nodulated and highyielding and the residual nitrogen benefits should be effectively captured by the following crop or pasture... Research by Mike Hughes, NSW DPI Grafton, and colleagues during the 1980s established that a 2.6 t/ha crop fixed about 265 kg N/ha (Hughes and Herridge 1989)... Bug thresholds for edible soybeans are considerably lower than for crushing beans and range from 0.33-0.6/m 2depending on crop size* (no of seeds per plant), the threshold being higher in larger crops...

As a green manure crop, soybeans provide good quantities of dry matter and large amounts of nitrogen... Better efficacy could be obtained by using smaller nozzles and lower water rates on small weeds... The problem with the system in the wet tropics is that decomposition is rapid and much of the available nitrogen will be lost through leaching or denitrification under waterlogged conditions...
