A 2018 study found that Bt-corn protected nearby fields of non-Bt corn and nearby vegetable crops, reducing the use of pesticides on those crops. Data from 1976 to 1996 (before Bt corn was widespread) was compared to data after it was adopted (1996–2016). They examined levels of the European corn borer and corn earworm. Their larvae eat a ...
In 1996, genetically modified maize producing Bt Cry protein was approved, which killed the European corn borer and related species; subsequent Bt genes were introduced that killed corn rootworm larvae. [60] The Bt genes engineered into crops and approved for release include, singly and stacked: Cry1A.105, CryIAb, CryIF, Cry2Ab, Cry3Bb1 ...
Corn line MON802 was developed through genetic modification to be tolerant [3] to glyphosate herbicide and protect the plant from the European corn borer (Ostrinia nubilalis) (the Bt trait). [4] MON 809 is an Insect Resistant maize under license from Monsanto. [5]
Farmers generally use less insecticide when they plant Bt-resistant crops. Insecticide use on corn farms declined from 0.21 pound per planted acre in 1995 to 0.02 pound in 2010. This is consistent with the decline in European corn borer populations as a direct result of Bt corn and cotton. The establishment of minimum refuge requirements helped ...
The oldest type of sweet corn contains more sugar and less starch than field corn intended for livestock. Tends to be heartier in respect to planting depth, germination and growth than other types. Begins conversion of sugar to starch after peak maturity or harvest, and as such is best eaten immediately after harvest.

These genetically modified plants with Bt protein are grown on a large scale around the world. [2] Monsanto's corn line MON 810 is produced by ballistically transforming another corn line with a plasmid, PV-ZMCT10. [3] This plasmid has a cauliflower mosaic virus 35S promoter and hsp70 maize intron sequences which drive the expression of the ...
