Corn, (Zea mays), also called Indian corn or maize, cereal plant of the grass family and its edible grain. B73). The susceptibility of maize to the European corn borer and corn rootworms, and the resulting large crop losses which are estimated at a billion dollars worldwide for each pest,[94][95][96] led to the development of transgenics expressing the Bacillus thuringiensis toxin. This involved a large number of workers and associated social events (husking or shucking bees). How about field corn? This genetic tolerance is very rarely found in nature.

Here is Roberta Lee Studie-Maize’s obituary. Today, all such technologies, from entirely manual harvesting to entirely mechanized, are still in use to some degree, as appropriate to each farm's needs, although the thoroughly mechanized versions predominate, as they offer the lowest unit costs when scaled to large farm operations. There are two major species of the genus Zea (out of six total): Zea mays (maize) and Zea diploperennis, which is a perennial type of teosinte.
