“…If leaves do emerge, they often do not unroll completely, trapping the tip of the next developing leaf and causing it to form a loop (see cover photograph). The primary anatomical sites affected in grasses are the developing leaves beneath the coleoptile and the apical and intercalary meristems, near the coleoptilar node (16,24,27,58). Root growth also can be inhibited but is generally less sensitive than shoot growth (3,25,27,56).…”

“…Chloroacetamide and thiocarbamate herbicides are absorbed by both shoot and root. Grass species are generally more susceptible when the herbicide is absorbed by the emerging shoot, especially when absorbed near the coleoptilar node (1,27,36,37,58,59), but root absorption may also contribute to shoot injury (27). Translocation of these herbi cides can occur both in the xylem and phloem (1,13,15,54,55,57).…”

Understanding the Mode of Action of the Chloroacetamide and Thiocarbamate Herbicides

Chloroacetamide and thiocarbamate herbicides have many properties in common: both herbicide classes are effective only as preemergence herbicides; they inhibit early seedling growth and cause similar injury symptoms in susceptible species; they are detoxified in plants by glutathione conjugation; they have a similar spectrum of selectivity; they can be applied safely in certain susceptible grass crops when applied with antidotes; and they can inhibit the synthesis of lipids, isoprenoids, and other metabolic processes requiring coenzyme A. It can be hypothesized that these similarities are due to the ability of the chloroacetamides and the sulfoxide of thiocarbamates to bind covalently to enzymes, coenzymes, or metabolic intermediates containing sulfhydryl (-SH) groups.

“…Thiocarbamates are absorbed via the root or shoot and subsequently inhibit fatty acid and lipid biosynthesis in susceptible grass and broadleaf species (Fuerst 1987). In grasses, the developing leaves beneath the coleoptile and apical intercalary meristems are the primary sites affected (Dawson 1963;Grey and Joo 1978). EPTC is a thiocarbamate herbicide once widely used in corn (Zea mays L.) infested with perennial grasses.…”

Conversion of ‘Tifway’ Bermudagrass Stands to ‘Zorro’ Zoysiagrass Turf using Combinations of Dazomet and EPTC

et al. 2011

Field experiments were conducted to evaluate the efficacy of herbicides and soil sterilants for the fairway conversion of ‘Tifway’ bermudagrass to ‘Zorro’ zoysiagrass. Treatments included glyphosate (4.48 kg ae ha−1), EPTC (7.84 kg ai ha−1), dazomet (338 kg ai ha−1), siduron (13.4 kg ai ha−1), glyphosate plus ETPC (4.48 + 7.84 kg ha−1), glyphosate plus dazomet (4.48 + 338 kg ha−1), EPTC plus siduron (7.84 + 13.4 kg ha−1), and dazomet plus siduron (338 + 13.4 kg ha−1). Glyphosate treatments were applied 5 wk prior to establishment (WPE), dazomet and EPTC treatments were applied 3 WPE, and siduron was applied at establishment. Dazomet and EPTC treatments were incorporated to a depth of 10 to 15 cm with a rotary tiller and rolled with a weighted roller to reduce losses from volatilization after application. Zorro zoysiagrass was established in June 2008 and 2009 using a mixture of rhizomes and stolons at a rate of 76 cm3m−2. Results indicate that glyphosate + dazomet, glyphosate + EPTC, dazomet + siduron, and EPTC + siduron were equally effective at controlling Tifway bermudagrass. EPTC and dazomet controlled bermudagrass more effectively when used in combination with glyphosate or siduron. There were no significant differences in bermudagrass cover between the EPTC combinations with glyphosate or siduron and dazomet applied with glyphosate or siduron. Comparing EPTC- and dazomet-alone, EPTC yielded less bermudagrass cover (32%) than dazomet (71%). At present, research is limited on using EPTC for controlling perennial grasses in turfgrass systems. Data from these studies demonstrate the potential use of EPTC as a preplant soil herbicide to control hybrid bermudagrass during zoysiagrass renovation.
