Crop plant-compatible herbicidal compositions containing herbicides and safeners

Abstract

Disclosed herein are herbicidal compositions, characterized in that they comprise: A) an antidotically effective amount of one or more safeners from the group of the phosphorated esters of the formula (I): wherein T and T1 are independently selected from the group of hydrogen, alkyl, haloalkyl, alkoxyalkyl, alkenyl, and alkynyl; U is O or S, and V, W, X, Y, and Z are independently selected from the group of hydrogen, halogen, alkyl, haloalkyl, and alkoxy; and B) one or more sulfonamide or sulfonylurea herbicides selected from the group consisting of amidosulfuron, azimsulfuron, bensulfuron-methyl, chlorimuron-ethyl, chlorsulfuron, cinosulfuron, cyclosulfamuron, ethametsulfuron-methyl, ethoxysulfuron, flupyrsulfuron-methyl, flazasulfuron, foramsulfuron, halosulfuron-methyl, imazosulfuron, iodosulfuron-methyl, mesosulfuron-methyl, metsulfuron-methyl, nicosulfuron, oxasulfuron, primisulfuron-methyl, prosulfuron, thifensulfuron-methyl, tribenuron-methyl, trifloxysulfuron, triflusulfuron-methyl, triosulfuron, cloransulam-methyl, diclosulam, florasulam, flumetsulam, metosulam, penoxsulam, and combinations thereof, and methods for using the same.

Description

technical field [0001] Crop protection compositions useful against unwanted vegetation are disclosed herein which comprise as active compounds a combination of at least one herbicide and at least one safener. Background technique [0002] Herbicides are used to control unwanted vegetation (ie weeds) which could otherwise cause significant damage to desired plant species (eg crop plants or ornamental plants). Many potent herbicides are capable of controlling a broad spectrum of grasses and broadleaf weeds that compete with desired plants or crops such as wheat, cotton or corn (corn) at low application rates throughout the growing season. Unfortunately, certain strong herbicides are not tolerated or phytotoxic to large numbers of desired plants when applied at frequencies effective to control unwanted plants. For example, a large number of sulfonamide or sulfonylurea herbicides cannot therefore be used with sufficient selectivity on maize, rice or cereals. Phytotoxic side ef...

Problems solved by technology

Although other herbicides are mentioned in this disclosure, the only herbicide specifically exemplified is clomazone, and the only available results are tests on corn and cotton seeds, with no results provided for post-emergence applications
