Because of its increasing destructiveness in some of the important carrot growing sections of New York State an effective method for the control of the carrot rust fly, Psila rosae, has been urgently needed.

As a result of four seasons' study, at least four methods of control have been developed by which the insect may be successfully combated.

In the case of large scale operations two effective methods are available which involve comparatively slight modifications in existing cultural practices.

For the smaller grower injury may be prevented by the intelligent use of mercurous chloride preparations or by the employment of mechanical barriers such as cheesecloth screens.
