  • Publication number: 20050009702
    Abstract: The present invention relates to protection of plants from unintended phytotoxic injury due to application of a herbicide to reduce competition for the plant of interest. A preferred herbicide used in the context of the present invention is clomazone. The unintended phytotoxic injury is avoided by application of a safening-effective amount of one or more of the compounds described by formula (I) wherein T and T1 are independently selected from the group of hydrogen, alkyl haloalkyl alkoxyalkyl, alkenyl and alkynyl; U is oxygen or sulfur, and; V, W, X, Y, and Z are independently selected from the group of hydrogen, halogen, alkyl, haloalkyl, and alkoxy. The present invention is preferably used for growing corn, wheat, and cotton in the presence of the otherwise phytoxic effects of clomazone, for example.
