Gauvrit C & Chauvel B (2010). Sensitivity of Ambrosia artemisiifolia to glufosinate and glyphosate at various developmental stages. Weed Research50, 503–510. Summary Glufosinate and glyphosate at 375 g a.i. ha−1 and 540 g a.e. ha−1, respectively, were assessed for control of Ambrosia artemisiifolia under non‐crop conditions at four different developmental stages (vegetative, BBCH 14; bud appearance, BBCH 53–55; onset of pollen production, BBCH 61; mid female flowering, BBCH 73–77). Both herbicides displayed high efficacies at all development stages. However, after treatments at BBCH 14, new emergence or re‐growth of A. artemisiifolia led to the presence of plants that produced pollen and seeds. Treatments at BBCH 53–55 gave more than 99.9% reduced pollen production. Seed production was more than 99.9% reduced by glyphosate and 92.0–99.8% by glufosinate. Treatments at BBCH 61 suppressed viable seed production by more than 99.8%. When treatments were made at BBCH 73–77, seed production by A. artemisiifolia was not significantly affected, but seed viability was decreased by 10–85%. Although significantly reduced, the number of viable seeds was still 283–652 and 827–3893 m−2 in the plots treated by glufosinate and glyphosate respectively. It is concluded that on non‐crop areas, herbicide treatment of A. artemisiifolia at bud appearance (BBCH 53–55) with glufosinate or glyphosate gave the most effective control of both pollen and seed production.

Competitive interactions in mixtures of broccoli and Chenopodium album grown at two UV‐B radiation levels under glasshouse conditions

Ultraviolet-B radiation effects on intra-and interspecific competition in broccoli (Brassica oleracea) and Chenopodium album were studied using bivariate factorial experiments. A randomized block design was used in which three monoculture densities for each species [144 (low), 256 (medium), and 400 (high) plants m )2 ] and all binary combinations were grown in a glasshouse at two (4 and 7 kJ m )2 day )1 ) UV-B BE radiation levels for 4 weeks in 1999 and 5 weeks in 2000. Inverse yield-density relationships were more discernible at 4, compared with 7 kJ m )2 day )1 UV-B BE radiation. Substitution rates, indicating the balance of intra-to interspecific competitive effects, declined for broccoli at 7, compared with 4 kJ m )2 day )1 UV-B BE radiation, largely because of reduced interspecific competitive influences. Conversely, substitution rates increased for C. album grown at 7 kJ m )2 day )1 UV-B BE radiation, as a result of both decreased intraspecific and increased interspecific competition. Interspecific competitive effects were influenced more than intraspecific competitive effects by UV-B radiation. Based on relative magnitude of substitution rates, C. album was a stronger competitor than broccoli at 4 kJ m )2 day )1 UV-B BE radiation in both years, and at 7 kJ m )2 day )1 UV-B BE radiation in 1999. In 2000, broccoli was the stronger competitor at 7 kJ m )2 day )1 UV-B BE radiation. Overall, the relative competitiveness of broccoli was enhanced, while that of C. album diminished at 7, compared with 4 kJ m )2 day )1 UV-B BE radiation. These findings indicate that above-ambient UV-B radiation has the potential to alter crop-weed competitive interactions, which could change acceptable weed threshold levels.

“…Common ragweed can emerge in late April as soil warms and will continue to emerge until temperatures become unfavorable sending the seeds back into dormancy (Jordan et al, 2014). Coble et al (1981) reported that 0.11 common ragweed/m 2 reduced soybean yield by 32.5 kg/ha on average. When grown in 30% shade, common ragweed has been noted to grow just as well as sweet corn (Zea mays L. var.…”

Field studies were conducted in 2016 and 2017 at two locations in North Carolina to evaluate common ragweed (Ambrosia artemiisifolia L.) (Lewiston-Woodville) and Palmer amaranth (Amanthus palmeri S. Wats) control (Rocky Mount), peanut (Arachis hypogaea L.) yield, and estimated economic return when herbicides were applied postemergence (POST) at 2 or 6 weeks after planting (WAP); 2 and 4 WAP; 4 and 6 WAP; and 2, 4, and 6 WAP. During the following growing season, cotton (Gossypium hirsutum L.) was planted directly into the same plots to determine the impact of weed management during the previous season on weed density. In absence of herbicides, peanut yield was 880 and 1110 kg/ha at Lewiston-Woodville and Rocky Mount, respectively. When weed control depended on a single herbicide application, yield ranged from 1760 to 2660 kg/ha at Lewiston-Woodville, and 2080 to 2480 kg/ha at Rocky Mount. When herbicides were applied twice, peanut yield ranged from 2690 to 3280 kg/ha at Lewiston-Woodville and 3420 to 3840 kg/ha at Rocky Mount. The greatest yields were recorded when herbicides were applied two or three times. Applying herbicides increased the estimated economic return of peanut compared to the non-treated control (NTC). In cotton the following year, common ragweed populations at Lewiston-Woodville were greater following the NTC or a single herbicide application 2 WAP compared to more intensive herbicide programs. Palmer amaranth density at Rocky Mount the following year in cotton was not affected by weed management the previous year in peanut. These results illustrate the relative importance of timing and duration of weed management for peanut and how they influence weed emergence in the following cotton rotational crop.
