“…Hamilton (1971) reported MSMA to be more effective than 2,4-D, aminotriazole or paraquat against nutgrass. Holt et al (1967) showed that tubers accumulate As by translocation, but found no relationship between As content and ability to produce new shoots. Death of tubers was considered to be due to depletion of tuber reserves and/or bud supply rather than associated with a specific As level.…”

Summary: Résumé: Zusammenfassung Soil‐incorporated butylate, EPTC and vernolate had only small effects on nutgrass (Cyperus rotundus L.) shoot numbers and the germination of recovered tubers. MSMA, 2,4‐D, glyphosate and cyperquat all killed top growth and reduced the germination of recovered tubers in both field and pot trials. Naptalam increased shoot number and tuber production. Foliar sprays of abscisic acid, chlorflurenoi and CCDP (3‐carboxy‐1‐(p‐chlorophenyl)‐4,6‐dimethyl‐2‐pyridone) had little or no effect. Ethephon slightly increased the number of attached tubers with shoots, but NIA 10637 (.ethyl hydrogen‐1‐propylphosphonate) had inconsistent efl'ects. MH inhibited tuber bud germination, TIBA increased shoot numbers slightly, and daminozide reduced tuber production and the germination of detached tubers. None of the growth regulators tested appears potentially useful for nutgrass control. Expériences avec le Cyperus rotundus L. II. Action de quelques herbicides et substances de croissance Le butylate, l'EPTC et le vernolate incorporés au sol n'ont eu que peu d'efficacité contre le cyperus (Cyperus rotundus L.) en ce qui concerne le nombre de pousses et la germination des tubercules récoltés. Le MSMA, le 2,4‐D, le glyphosate et le cyperquat ont tous détruit la zone terminale de croissance et réduit significativement la germination des tubercules récoltés dans les essais, soit au champ, soit en pots. Le naptalame a augmenté le nombre de pousses et la production de tubercules. Des pulvérisations sur les feuilles d'acide abscissique, de chlorflurénol et de CCDP (3‐carbo.xy‐1‐(p‐chlorophényl)‐4,6‐diméthyl‐2‐pyridone) n'a eu que peu ou pas d'effets. L'ethéphon a légérement accru le nombre de tubercuies fixés aux racines, mais le NIA 10637 (hydrogéne‐1‐propylphosphonate d'éthyle) n'a eu que des effets incohérents. L'hydrazide maléique a inhibé la germination du bourgeon du bulbe, le TIBA a accru légérement le nombre de pousses, et le daminozide a réduit la production des tubercules et la germination des tubercules détachés. Aucune des substance de croissance essayées n'apparait potentiellement utilisable pour la lutte contre le cyperus. Versuche mit Cyperus rotundus L. II. Wirkung einiger Herbizide und Wachstumsregulatoren In den Boden eingearbejtetes Butylat, EPTC und Vernolat hatte nur eine geringe Wirkung auf die Anzahl der Sprosse und den Austrieb der Knollen von Cyperus rotundus L. MSMA, 2,4‐D, Glyphosate und Cyperquat toteten die oberirdischen Pflanzenteile ab und verringerten den Austrieb der Knollen in Feld‐ als auch in Gefässversuchen. Naptalam bewirkte eine Zunahme der Sprosszahl und erhöhte die Knollenbildung. Blattspritzungen mit Abscisinsäure, Chlorflurenoi und CCDP (3‐Carboxy‐1‐(p‐chlorphenyl)‐4,6‐di‐methyl‐2‐pyridon) hatten eine geringe oder gar keine Wirkung. Durch Ethephon nahm die Anzahl der Knollen mit Sprossen zu, NIA 10637 (Äthyl hydrogen‐1‐propylphospho‐nat) hingegen zeigte widersprüchliche Wirkungen. MH hemmte den Austrieb der KnoUenknospen, TIBA förderte leicht die Zahl der Sprosse und...

“…Therefore, it appears necessary to use a minimum of three applications of D. higginsii at 10 6 conidia/ ml or higher to effectively reduce purple nutsedge growth in the field. Single applications of other control measures, such as chemical herbicides or cultivation, are also ineffective for this weed (Amerasinghe 1992;Holt et al 1967;Komai and Ueki 1982;Marambe 1996;Santos et al 1997;Zandstra and Nishimoto 1977). Further work is needed to develop management strategies for the use of D. higginsii as a bioherbicide for purple nutsedge.…”

An isolate of the fungus Dactylaria higginsii obtained from purple nutsedge in Florida was highly pathogenic to Cyperus spp. The potential of this isolate as a bioherbicide was field tested in natural populations of purple nutsedge in Gainesville and Jay, FL. The fungus was applied in 0.5% Metamucil® as a carrier, and the treatments were: carrier only, 105 conidia/ml + carrier, and 106 conidia/ml + carrier. Treatments were applied as single, double, or triple postemergence (POST) sprays at biweekly intervals. The disease and secondary infections developed in about 5 and 15 d after inoculation, respectively, killing most of the infected leaves. All weed growth parameters and disease progress rates were affected by inoculum dosage and inoculation frequencies. Three inoculations, each at 106 conidia/ml, provided effective control of purple nutsedge compared to a single inoculation, as measured by shoot dry weight, tuber numbers, and tuber dry weight. Higher rates of disease progress and disease levels, defined by the area under the disease progress curve (AUDPC), occurred with three inoculations at 106 conidia/ml. Disease progress was slower and the level of weed control was lower at 105 conidia/ml compared to the higher inoculum level. Three applications of 106 conidia/ml provided >90% nutsedge control. Dactylaria higginsii appears to be an effective bioherbicide candidate deserving further development for commercial use.

“…since basi petal translocation results in rhizome control (5). Likewise, MSMA and DSMA reduce sprouting and regrowth in yellow nutsedge (Cyperus esculentus L.) and purple nutsedge (Cyperus rotundus L.) due to translocation to basal bulbs and lateral movement into tubers (3). Safety and tolerance of ~!SMA and DSMA applications in cotton have been doumented (1, 8).…”

Woolyleaf bursage (Franseria tomentosa Gray) infests approximately 70,000 ha of cropland in Great Plains states. Since susceptibility of this weed to MSMA (monosodium methanearsonate) was observed, MSMA and DSMA (disodium methanearsonate) were investigated under several conditions for control of woollyleaf bursage. The most effective control occurred when MSMA was applied in mid to late May after all shoots had emerged in the spring. Experiments were conducted in playa lakebeds on Randall clay (Udic Pellusterts). Woollyleaf bursage was consistently more susceptible to MSMA than DSMA. Roots were killed to depths of 30 cm or more. Mold‐board plowing of infested areas delayed, rather than reduced, shoot emergence. In contrast, a disking operation allowed weed shoots to emerge earlier and more uniformly, which resulted in greater effectiveness of MSMA. Soil moisture and crop yields were increased when MSMA was applied to woollyleaf bursage before planting cotton (Gossypium hirsutum L.). One year after treatment with MSMA, woollyleaf bursage control was still evident and sudangrass [Sorghum sudanense Stapp (‘Piper’)] yields were increased in treated areas.
