Scientists Reveal New Threat to Cereal Crop Production
September 19, 2012| |
Scientists from Rothamstead Research, an England-based Crop Research Center, have identified a growing threat from the grain aphid (Sitobion avenae), a major cereal crop pest that can reduce farmers' yields by damaging and spreading plant diseases.
Rothamstead Research revealed that grain aphids are becoming more resistant to the popular pyrethroid insecticides as the frequency of grain aphids carrying the knock-down resistance (kdr) mechanism to the said insecticide has gradually increased this year.
Two new publications have been released which will assist with management of grain aphids this autumn, including best practice measures to limit the risk of resistance and strategies that could be deployed if resistance is suspected during the autumn spraying period.
