Herbicide Tolerance — Sweet Corn

Zea mays L. subsp. mays (Sweet Corn Group)

The ability of sweet corn hybrids to withstand chemical exposure without reducing yield or quality. This trait is critically important due to the high sensitivity of the sweet corn group to post-emergence herbicides used on field corn.

In the reference 17 varieties crop Sweet corn, where this is mentioned in the description.

To assess tolerance, a visual method is used with a damage scale ranging from 0% to 100%, where 0% denotes no symptoms and 100% indicates plant death. In laboratory conditions, screening is performed by germinating seeds in the presence of herbicides and testing at elevated dosages exceeding the standard rate by 2–16 times to determine the sensitivity limits of genotypes.

Hybrids are classified as tolerant, intermediate, sensitive, and highly sensitive depending on the risk of damage. The use of tolerant hybrids allows for effective weed control during critical crop growth phases without suppressing the plants, which prevents yield losses that can reach 40% or more.
