Abstract/Contents:Reports studies concerning chemical and physical properties of Isoxaben and its biological response to desirable and weedy plants after pre- and postemergent applications. Isoxaben is an amide with the chemical name N-[3- (1-ethyl-1-methylpropyl) -5-isoxazolyl] 2, 6-dimethoxy-benzamide. As compared to Oryzalin, isoxaben shows similar vapor pressure and U.V. light stability under field conditions, and can also be surface applied and water activated with minimal loss. In excessive irrigation, isoxaben leaches slightly more than Oryzalin but the majority remains in the weed germination zone. Tillage from 2.5 - 7.5 cm does not decrease herbicidal efficacy. Three and eight month samplings showed greated than 75% isoxaben remained in the upper 7.5 cm of the soil profile and greater than 50% of the original concentration remained after 1 year. Newly planted ornamentals, orchard corps and established turf are tolerant of osixabon at rates up to 2.24 kg/ha. 95%+ control is reported on 17 different broadleaf weeds from surface application at 3 different rates (.28-.56, .56-.84, .84-1.12 kg/ha). Exceptions to this include liggle and dwarf mallow (Malva spp.), wild oat (Aena fatua), barnyardgrass (Echimochloa crus-galli), and perennial weeds, i.e. field birdweed (Convolvulus arvensis), at rates of 1.12 - 2.24 kg/ha. A combination treatment may be desirable. Isoxaben 75DF is compatible with glyphosate, paraquat, oryzalin, trifluralin, and other auxin-type herbicides.
