Timing maleic hydrazide sprays to stage of plant development

  • Published:
American Potato Journal Aims and scope Submit manuscript

Summary

Maleic hydrazide sprays, 3 pounds per acre, applied at blossom fall gave consistently good sprout control. Sprays at this stage of plant development gave good results to potatoes planted early or late in the season.

Maleic hydrazide sprays had no effect on black spot or peeling discoloration. There was no consistent detrimental effect on chipping quality.

Late date of planting tended to decrease sprouting and black spot but had no consistent effect on specific gravity.
