Polychrosis viteana is now rated as the worst enemy of grapes in Delaware. Life History studies during 1928 show that nearly a full third brood developed in the vicinity of Camden while only a partial third brood took place at Newark. In the Camden section the earliest moths started to issue on May 28th but careful field observations showed that grape berry.moth eggs started general hatching in the field on June 25th. Under control, emphasis is placed on clean up of leaf accumulations in old hedge rows and grassy strips between vineyards, the use of a good sticker and spreader, and the timeliness, thoroughness, and manner of application.
