Field Peas A Potential Alternative to Chickpeas for trap Cropping in Central Queensland
Abstract
Central Queensland currently enjoys an ascochyta blight free status, however the use of chickpeas as a winter trap crop has created a potential risk for the introduction of the disease. To address his problem we evaluated three winter active legumes (popani vetch, namoi vetch and field peas) for their suitability to be substituted for chickpeas as a spring trap crop in central Queensland. Field peas were found to be highly attractive to egg laying Helicoverpa spp. moths, carrying on average 50-70 eggs per metre row for most of September, the period for which a trap crop should be most attractive under CQ conditions. Egg survival on field peas was low with only 27 +/- 3.5% of eggs surviving to hatch as opposed to 73 +/- 2.9% egg survival on chickpea. The results suggest that field peas may be a viable trap crop alternative for chickpeas that would avert potential problems associated with ascochyta blight in this region.
