“…Similar reductions in ground ivy cover compared with an untreated check were observed when aminocyclopyrachlor was applied in either fall or spring (Patton et al, 2013b). Despite excellent ground ivy control, aminocyclopyrachlor is no longer registered for use in turf due to injury to nontarget vegetation (Patton et al, 2013a).…”

Many turfgrass extension bulletins and herbicide labels recommend prolonging or suspending mowing practices 1 day or more before and/or after herbicide applications to increase efficacy. However, the effect of mowing timing on herbicide efficacy has not been sufficiently explored. Field experiments were conducted to evaluate the influence of herbicide selection and mowing timing relative to herbicide application on the control of ground ivy (Glechoma hederacea L.). The three mowing treatments included mowing 30 min before herbicide application, mowing 30 min after herbicide application, and not mowing for at least 7 days prior to and at least 3 days after herbicide application. Aminocyclopyrachlor resulted in the greatest reduction of ground ivy cover in 2011 and 2012. Like aminocyclopyrachlor, 2,4‐D ester and metsulfuron reduced ground ivy cover both years, while triclopyr reduced ground ivy cover as well as aminocyclopyrachlor in 2012. Although 2,4‐D + mecoprop (MCPP) + dicamba was not among the best performing herbicides, it reduced ground ivy cover compared with the untreated check in both years. There were no mowing or mowing‐by‐herbicide interactions on any of the rating dates. Thus, this research suggests that the timing of lawn mowing relative to herbicide application has little measurable impact on herbicide efficacy on ground ivy.

“…MT50 values of aminocyclopyrachlor were higher in sandy clay (1376 days), intermediate in loamy sand (1128 days), and lower in clay soil (877 days) (p < 0.05). The data regarding aminocyclopyrachlor mineralization recorded in this study indicate that the herbicide has a relatively long persistence in all soils and thus could provide prolonged weed control in drought years and this herbicide has high leaching potential, particularly in wet years, since Francisco et al reported that aminocyclopyrachlor was detected at all depths (0-30 cm) in the agricultural soils and can cause damage to sensitive plants, such as tomatoes [28], soybean, and beet [29].…”

Soil Factors Effects on the Mineralization, Extractable Residue, and Bound Residue Formation of Aminocyclopyrachlor in Three Tropical Soils

Abstract:Aminocyclopyrachlor is an herbicide that belongs to the new class of chemicals known as the pyrimidine carboxylic acids, which are used to control broadleaf weeds and brush. However, the environmental behavior and fate of aminocyclopyrachlor are not fully understood. The aim of the present study was thus to evaluate the mineralization, extractable residue and bound residue formation of aminocyclopyrachlor in three tropical soils with different physico-chemical properties. 14 C-labeled [pyrimidine-2-14 C] aminocyclopyrachlor was used to assess the fate of this herbicide in soil placed in biometer culture flasks. Total mineralization (accumulated 14 CO 2 ) of aminocyclopyrachlor was found to be <10% in all soils, decreasing in the following order: Oxisol-Typic Hapludox (clay) > Oxisol-Typic Hapludox (loamy sand) > Plinthosol-Petric (sandy clay). Overall, constant rate of mineralization (k) values for all soils were very low (0.00050% to 0.00079% 14 CO 2 day −1 ), with mineralization half-life times (MT50) consequently very high (877 to 1376 days), suggesting potential long persistence in soil. The amount of extractable residues decreased from~31% to 50% in all soils after 126 days of incubation, indicating an increase in bound residue formation from~5.0-to 7.5-fold compared to evaluation immediately after herbicide application, suggesting that degradation herbicide is involved in the formation of bound residues. Extractable residues are important factors that control mineralization and bound residue formation from aminocyclopyrachlor in the soil. The present study is the first to assess the fate, distribution, and formation of bound residues of aminocyclopyrachlor in soils. Aminocyclopyrachlor residues were predominantly associated with the OM and clay contents of soil. This effect of soil physico-chemical properties should be considered in environmental risk assessment of aminocyclopyrachlor and its application in the field for weed control.

“…However, Brecke et al (2010) reported centipedegrass to be tolerant (<20% injury) at rates as high as 0.20 lb a.i./acre. Registration of Imprelis within turfgrass has now ceased, due in part to the potential for damage to sensitive landscape plants (Patton et al, 2013). However, when used in range and pasture scenarios, results presented here indicate that aminocyclopyrachlor will effectively control common lespedeza.…”

Common lespedeza or Japanese clover [Kummerowia striata (Thunb.) Schindl. syn. Lespedeza striata (Thunb.) Hook. & Arn.] is a difficult to control weed in many turf species of the United States. The slow establishment rate, sparse canopy, and low fertility requirements of centipedegrass [Eremochloa ophiuroides (Munro) Hack.] make this leguminous weed particularly problematic. Additionally, herbicide safety toward centipedegrass can limit postemergence broadleaf herbicide options in warm weather. A 2‐year field study was conducted to evaluate common lespedeza response and centipedegrass turf injury to several available broadleaf herbicides and commercial tank‐mixtures during peak summer conditions. Fluroxypyr (0.47 lb acid equivalent [a.e.]/acre) alone and Escalade 2 (a prepackaged tank‐mixture of 2,4‐D, fluroxypyr, and dicamba at 1.5 lb a.e./acre) effectively controlled common lespedeza without unacceptable turfgrass injury (≤18%, 2 weeks after treatment). Aminocyclopyrachlor (0.07 and 0.09 lb a.e./acre), which is no longer registered for use within fine turf scenarios, effectively controlled common lespedeza; however, the resulting centipedegrass injury (≥30%, 2 weeks after treatment) would likely be deemed unacceptable in many turfgrass scenarios. This research also highlights several commercially available herbicides routinely used for broadleaf weed control that failed to adequately control common lespedeza.
