Progression of transgenic plants
Environmental benefitsHerbicide tolerant crops have increased and encouraged no-till agriculture– less soil erosion.Over 1 million gallons of unsprayed insecticide per year.
(Kovach et al. (1992)
The EIQ value is multiplied by the amount of pesticide active ingredient (ai) used per hectare to produce a field EIQ value.
For example, the EIQ rating for glyphosate is 15.3. By using this rating multiplied by the amount of glyphosate used per hectare (eg, a hypothetical example of 1.1 kg applied per ha), the field EIQ value for glyphosate would be equivalent to 16.83/ha.
In comparison, the field EIQ/ha value for a commonly used herbicide on corn crops (atrazine) is 22.9/ha.
