Identification of Broadleaf Weeds in Citrus

Rimsulfuron Tank Mixed with Flumioxazin, Pendimethalin, or Oryzalin for Control of Broadleaf Weeds in Citrus

Herbicides are usually applied multiple times by growers for season long weed control in Florida citrus (Citrus sp.). Rimsulfuron, a sulfonylurea herbicide has been recently registered for control of certain grasses and broadleaf weeds in citrus. To increase the weed control spectrum and reduce application cost, citrus growers often prefer to tank mix herbicides. Field experiments were conducte...

Sulfonylureas Target ALS Enzyme to Control Grasses, Broadleaf Weeds

The herbicidal properties of sulfonylureas (SU's) were first reported in 1966 (Koog, 1966). The early SU's were derivatives of triazine herbicides. George Levitt of DuPont noted that SU's having aniline as the aryl group exhibited weak plant-growth regulatory activity while the aminopyrimidine derivative displayed very high biological activity (Levitt, 1983; Sauers and Levitt, 1984). Soon compa...

Evaluation of broadleaf weeds control with some post-emergence herbicides in maize (Zea mays L.) in Iran

Registered dose of herbicides may be higher than rate required for controlling weed species depending on growth stages. In order to study the effect of individual post-emergence application of 2,4-D plus MCPA and three sulfonylurea herbicides at four- to six-true leaf stage of weeds, experiments were conducted in 2011 at the greenhouse of Agricultural Faculty of Ferdowsi University of Mashh...

Control of broadleaf weeds with post-emergence herbicides in four barley (Hordeum spp.) cultivars

Limited information is available on control of broadleaf weeds in barley and response of barley cultivars to herbicides. Field experiments were conducted from 2007 to 2009 to evaluate post-emergence herbicides for control of broadleaf weeds in four barley cultivars. Herbicide treatments included 2,4-D sodium salt at 500 g ai ha 1, carfentrazone-ethyl at three rates (15, 20 and 25 g ai ha 1), an...

Risk Assessment for Section 3 Use of Pendimethalin Product Prowl 3.3 Ec in California for the Control of Broadleaf Weeds and Grasses on Bearing Citrus Crops
