Hart Winter Walk: virus explained to growers.. Ms Davidson explained that when growers first started reporting widespread damage in June it was initially put down to incorrect herbicide use, but as more crops started showing yellowing leaves a different picture emerged... Crops such as chickpeas, lentils and field peas had not emerged when the first round of the virus hit, but Ms Davidson told growers that pulses will also be susceptible to BWYV in spring...

Ms Davidson explained that when growers first started reporting widespread damage in June it was initially put down to incorrect herbicide use, but as more crops started showing yellowing leaves a different picture emerged... "If crops show patchy infection it may be necessary to control the aphids to prevent further spread of the virus into unaffected parts of crops during late winter and spring.".. Crops such as chickpeas, lentils and field peas had not emerged when the first round of the virus hit, but Ms Davidson told growers that pulses will also be susceptible to BWYV in spring...

BYDV has a wide host range which includes all the winter cereals (wheat, barley, oats, durum and triticale) and over 150 grass species... BYDV is generally spread to cereal crops in autumn and early winter by aphid flights from infected grasses which transmit the virus when they feed... BYDV affects the vascular system of infected plants restricting water and nutrient movement up the stem...

The disease caused by the fungus, Podosphaera fusca , is favoured by cooler growing conditions and is often widespread in late crops... It can cause significant yield loss if it develops before or at flowering, particularly if the crop is under moisture stress... There are strategies to minimise the risk of TSV infection: maintain farm hygiene, in particular the control of parthenium weed avoid planting mungbeans close to pastures, particularly those containing dense parthenium and other broadleaf weed infestations if crops are planted close to parthenium infested pastures either spray out pasture close to the mungbean crop or leave a buffer avoid planting mungbeans into marginal moisture, especially near parthenium infested pasture ensure planting seed is from crops with no signs of TSV...

Important economic diseases occurring in Queensland include seedling diseases ( Rhizoctonia and Pythium species), alternaria, black root rot, boll rots, bacterial blight, verticillium wilt and fusarium wilt... Grow only resistant varieties where diseases are known to occur, and closely adhere to planting guidelines to ensure a vigorous seedling... Hygiene measures include: ensuring machinery and vehicles that enter or leave the farm are free of dirt and crop debris keeping irrigation tailwater and run-off water on the farm controlling weeds within and around fields using a crop rotation strategy maintaining good soil nutrition levels minimising spillage and loss when transporting modules, hulls, cotton seed or gin trash...
