Blue corn differs from other corns in that it often has longer flowering period. This can affect a corn earworm control program. One, two or more applications of appropriate insecticides might be needed for effective control. Blue corn sold organically normally requires that the crop be grown without the use of either synthetic pesticides or synthetic fertilizers. Organic growers should consult their buyers for definitions of what they consider organically grown.
Birds can be a major pest on blue corn.
Propane guns are often used to frighten birds from fields. Because there are few commercial blue corn varieties, most growers develop their own strains. Blue corn strains are improved by selecting next year's planting seed from superior plants in the field before harvest. There are two phases in the selection process. Ears should first be selected from plants in the field with superior traits.
