“…‘Durana’ [18] stand varied by experiment each year and stand reductions were not observed for any herbicide treatment as compared to the nontreated control (data not shown). White clover exhibited tolerance to post-emergent applications of simazine and halosulfuron-methyl [19], but further research with indaziflam is needed.…”

Plantago lanceolata L. (buckhorn plantain) is an encroaching winter weed described as one of the most successful noncultivated colonizing species around the world. Control of P. lanceolata in southeastern USA Carya illinoinensis (Wangenh.) K. Koch production has not been studied, nor has the role of temperature on germination using a thermal gradient table. Seed of P. lanceolata collected from a Georgia C. illinoinensis grove were tested for the effects of temperature over time to establish differences in effects on germination using a thermal gradient table. Temperatures ranged from 13.5 to 30.5 °C for 288 h. Cumulative P. lanceolata seed germination was 66% occurring at 17.8 °C at 242 h. Over the 288 h experiment, maximum P. lanceolata germination was 27% occurring at 17.0 °C, 187 h after initiation. Control of P. lanceolata with residual herbicides, or in combination with 2,4-dichlorophenoxyacetic acid (2,4-D) was evaluated in the interrow of C. illinoinensis groves containing Trifolium repens L., and in greenhouse experiments. Pre- and post-emergent herbicides included indaziflam, halosulfuron-methyl, and simazine applied alone, or in combination with 2,4-D in late autumn after P. lanceolata emergence in a C. illinoinensis grove. Indaziflam in combination with 2,4-D controlled P. lanceolata greater than 90% when applied in C. illinoinensis groves and greenhouse experiments. Halosulfuron-methyl and simazine applied alone, or in combination with 2,4-D, provided 67% or less P. lanceolata control in the grove experiments, and 83% or less in greenhouse experiments. Results suggested that herbicide applications should be made during the time when diurnal temperatures are between 15 and 30 °C, while abiding pre-harvest interval restrictions. Post- and pre-emergent herbicides may aid in controlling emerged weeds and reducing further weed emergence during the autumn of that year.

“…Delaying the application until 2 wk after emergence resulted in at least a 2-fold reduction in pintoi injury from all rates of imazapic, sulfosulfuron, carfentrazone, the low rate of 2,4-D, and 2,4-D þ carfentrazone. Injury to other species in the Fabaceae family by 2,4-D appears to be species and rate dependent (Davy et al 2015;Leon et al 2014;McCurdy et al 2013McCurdy et al , 2016. For example, research by Evers et al (1993) indicated that injury (97%) from 2,4-D on berseem clover (Trifolium alexandrinum L.) was higher than that observed (16%) on rose clover (Trifolium hirtum All.)…”

Tolerance of pintoi peanut to PRE and POST herbicides

Pintoi peanut is a warm-season perennial legume that shows promise as a forage crop for the southeastern United States, however, little is known about the proper methods of weed management during establishment for this species. The objective of this study was to determine the ability of pintoi peanut to tolerate applications of PRE and POST herbicides during the year of and year after planting. The effects of herbicide treatments on percentage of visual estimates of injury and stand counts of pintoi peanut were investigated at Ona and Marianna, FL, in 2015 and 2016. All PRE herbicides did not result in significant injury or stand reduction. Pintoi peanut’s tolerance to POST herbicides was higher when plants were emerged for at least 2 wk prior to herbicide application. Stands of pintoi peanut that were planted the previous year appear to tolerate all herbicides examined in this work, except sulfosulfuron. Results of this study indicate that at the year of planting pintoi peanut is tolerant to PRE applications of pendimethalin, imazethapyr, and imazapic. Pintoi peanut appears to tolerate applications of 2,4-D, carfentrazone, imazapic and imazethapyr the year after planting at the rates utilized in this study. Future research should evaluate the effects of multiple herbicide applications and tank-mixes to obtain satisfactory weed control and selectivity in pintoi peanut swards.

“…The potential to use legumes in lawn grass systems has received some recent study (McCurdy et al., 2014; Sparks et al., 2015; McCurdy et al., 2016). Part of this has been driven by the introduction of lower growing, non‐forage cultivars which possess smaller leaves and a more compact growth habit making them compatible with many lawn grass species and typical lawn mowing heights of 5–8 cm (van der Heijden & Roulund, 2010).…”

Lawns require a steady supply of nitrogen (N) to maintain green color and seasonal shoot density. Excess N fertilization can lead to surface and groundwater contamination, suggesting a need for alternative turf fertilization strategies that reduce the reliance on frequent N applications. Grass-legume mixtures may be one solution since legumes, like white clover (Trifolium repens L.), biologically fix atmospheric N and add it to the soil via mineralization. This field study evaluated the growth, appearance and persistence of a cool-season grass and grass-legume mixture containing a low growing Trifolium repens, 'Microclover' (MC) with and without supplemental N fertilization (0 vs. 98 kg N ha −1 yr −1 ) over two growing seasons. Turf with MC and receiving supplemental N produced the most dry matter yield (DMY) 15583 kg ha −1 and the highest mean visual appearance. By contrast, unfertilized turf without MC produced the least DMY, 3815 kg ha −1 , and the poorest appearance, which lacked vigor and was negatively affected by leaf blighting diseases. The unfertilized turf with MC produced moderate growth, 8754 kg ha −1 , with an acceptable appearance. Clover populations decreased over time in both the unfertilized and fertilized grasslegume mixtures but less so where supplemental N was not applied. This decline in clover could possibly be remedied by periodic overseeding. In summary, these results suggest that a cool-season grass-clover lawn mixture can provide a persistent and visually acceptable lawn that would require less reliance on supplemental N fertilization.
