Description Key to Product-Herbicide Sensitivity Most herbicide injury problems that occur in corn relate to environmental interactions, rate, application and growth stage rather than specific differences among products in sensitivity to herbicide products. However, products do vary in their sensitivity to some herbicide families. Below is a description of the key used for the Product-Herbicide Sensitivity Table.
Trade Names of Herbicide Families Tested
|
The “lower sensitivity” designation indicates that the product does not usually exhibit injury symptoms to that family of herbicides when used according to label. Exceptions do occur, generally related to adverse environmental conditions. For instance, soil applied amide herbicides typically cause very little or no injury to most products. However, when germination and emergence are slow due to cold and wet conditions, the unemerged seedling may take up the chemical faster than it can metabolize it. In this case, injury symptoms may occur on a more significant level. |
|
The “moderate sensitivity” designation indicates that the product can occasionally show injury to that class of herbicides. These herbicides can be used safely with the product. With post-applied herbicides, the risk of injury is greatly reduced by applying the herbicide product early and at a low rate. |
|
The “higher sensitivity” designation indicates that the risk of injury to the product by that herbicide family is high enough that you may want to use a product from a different family. Injury from many of these products can often be avoided if they are applied at the earliest leaf stages allowed by the label and at a low rate. For corn at the later end of the labeled leaf stage, the use of drop nozzles reduces the chance of injury if the herbicide is kept out of the whorl. |
