Herbicide tolerant crops (HTC)

• Increased use of the herbicides plant is tolerant to (describes ecological impact eg toxic residues in soil, runoff into waterways)
• There may also be a decrease in use of other herbicides (benefit to environment eg more diversity of plants)
• Weed resistance may lead to increase in use of other more toxic herbicides (describes ecological impact)
• HTC plants could become weeds in subsequent crops as they become more difficult to eradicate
• less competition for the crop plant as the farmer can spray herbicide at anytime over crop
