Spraying Experiments in Nebraska 
21 
90 per cent; No. 4, 80 per cent; and No. 1, 73 per cent. It is 
impossible to account satisfactorily for the poor results in plat 
No. 1, except that this plat was the south row of the orchard 
and being on the outside was reinfested from other sources. 
Less than 2 per cent of the larvae entered the fruit at the calyx. 
Where coarse mist nozzles were used at the petal-fall spray, 
less than one per cent of calyx wormy apples were found.
