Cold! That is the best way to describe the first three and a half months of 2008. A cool spring has delayed alfalfa weevil hatch this year, however Iowa fields should have accumulated sufficient temperatures for larvae to hatch starting April 23-25 in southern Iowa. Naturally, weevils with hatch at slightly later dates in the central and northern counties of the state.
