Manuka Oil As a Potential Natural Herbicide
Manuka Oil as a Potential Natural Herbicide Franck E. Dayan and Daniel K. Owens USDA-ARS Natural Products Utilization Research Unit P.O. Box 8048, University, MS 38677 [email protected] In 1977, Gray observed that bottlebrush plant (Callistemon citrinus) repressed the growth of plants in its surroundings. Crude extracts from this plant caused the bleaching of grass weeds. He identified the active component as leptospermone, a natural triketone structure with no known biological activity that had been reported in a number of Australasian shrubs. Leptospermone was moderately active in greenhouse tests, controlling mostly small-seeded grass weeds. This natural product and a small number of synthetic structural analogs were patented as herbicides in 1980. A few years later, a separate group at the Western Research Center was generating analogs of the cyclohexanedione herbicide sethoxydim, an inhibitor or acetyl- coenzyme-A carboxylase. Some of the second generation herbicidal derivatives with a dimedone backbone caused bleaching symptoms similar to leptospermone. Combination of the syncarpic acid of leptospermone to this chemistry ultimately served as the basis for the development of the triketone synthetic herbicides (Fig. 1). Fig. 1. Struct ure s of the n a tural trik et o n e leptosperm one a nd t w o s y nthetic analogues that are sold as commer ci a l he r bic ides. Natural β-triketones are common in many Australasian woody plants (e.g., Leptospermum, Eucalyptus, Melaceuca, etc...). Steam distilled manuka oil account for 0.3% of the dried weight of L. scoparium. However, the amount of β-triketone present in these oils varies wildly across New Zealand. -

The Evaluation of HPPD-Inhibitors for Full-Season Control of Morningglory (Ipomoea) Species in Corn (Zea mays L.) by James Daniel Jones III A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 15, 2018 Keywords: Ipomoea, corn, HPPD, postemergence Approved by Dr. Dennis Delaney, Chair, Extension Specialist, Crop, Soil, and Environmental Sciences Dr. Andrew Price, Affiliate Associate Professor, Crop, Soil, and Environmental Sciences Dr. Audrey Gamble, Assistant Professor and Extension Specialist, Crop, Soil, and Environmental Sciences i Abstract Due to late-season morningglory harvest interference concerns in corn, field studies were conducted in 2017 and 2018 at the Prattville Agricultural Research Unit in Prattville, Alabama and at the Sand Mountain Research and Extension Center in Crossville, Alabama to evaluate late season control of morningglory species using HPPD- inhibitors postemergence (POST) applied alone, following atrazine preemergence (PRE), or in combination with atrazine. Additionally, Amaranthus spp. and Senna spp. were evaluated for control. An incomplete randomized design with a split-plot treatment arrangement with four replications was utilized. The trial was divided into two sections: one with a PRE application of atrazine and a second without a preemergence application of atrazine. Eleven herbicides were applied POST without atrazine including: tembotrione; mesotrione; topramezone+dimethenamid; mesotrione+S- metolachlor+glyphosate; tembotrione+thiencarbazone; topramezone; mesotrione+S- metolachlor+atrazine; mesotrione+S-metolachlor+atrazine+bicyclopyrone; mesotrione+nicosulfuron; isoxaflutole; isoxaflutole+thiencarbazone-methyl; non-treated with atrazine applied PRE, and a true non-treated check. The same herbicides, excluding the two treatments that contain atrazine in the premixture, were also applied with atrazine. -
Use of Mesotrione for Annual Bluegrass (Poa Annua L.) at Cool
USE OF MESOTRIONE FOR ANNUAL BLUEGRASS (POA ANNUA L.) AT COOL- SEASON TURFGRASS ESTABLISHMENT by KATELYN A. VENNER A Thesis submitted to the Graduate School-New Brunswick Rutgers, The State University of New Jersey in partial fulfillment of the requirements for the degree of Master of Science Graduate Program in Plant Biology written under the direction of Stephen E. Hart Ph.D. and approved by ________________________ ________________________ ________________________ New Brunswick, New Jersey October, 2011 ABSTRACT OF THE THESIS USE OF MESOTRIONE AT COOL-SEASON TURFGRASS ESTABLISMENT By Katelyn Anne Venner Thesis director: Stephen E. Hart Annual bluegrass is a problematic weed in highly maintained turfgrass environments, and is difficult to control due to its adaptability to highly maintained turfgrass environments and lack of highly effective chemical control options. Mesotrione is a relatively new herbicide which has been found to show some level of control of annual bluegrass, and is safe to use at cool season turfgrass establishment. Thus, mesotrione has potential to be utilized for weed control in cultivated sod production. The objectives of this research were to evaluate mesotrione to determine: 1) tolerance of selected tall fescue cultivars, an important turfgrass species cultivated for sod, to applications of mesotrione; 2) the length of residual of mesotrione versus prodiamine, bensulide and dithiopyr for control of annual bluegrass; and 3) potential of mesotrione to control winter annual broadleaf weeds at Kentucky bluegrass establishment. Tall fescue cultivars were found to be tolerant to mesotrione applications made preemergence and preemergence plus 4 weeks after emergence at higher rates than required for weed control. -

Vol. 26 No. 3 December 2015 It’s the Thought That Counts... It’s the time of year to look forward to spending time with family and showing each other how much we care by giving the perfect gift. This isn’t limited to just humans though, insects exhibit this kind of behaviour too! Family time in ambrosia beetles: The majority of ambrosia beetle species tunnel Alberta’s eye into the heartwood of weakened trees, where they cultivate fungus as a food source. Like termites, bees, and ants, many ambrosia beetles are eusocial; they on forest live in colonies with many individuals and overlapping generations. Just like health human families, every individual in the colony has their job. The brood are respon- sible for enlarging the gallery and sweeping up the poop (frass). Adults protect the brood and shuffle the frass balls out of the gallery, while everyone helps take care Issue highlights: of the fungus garden. And as with many human families, the mother runs things: The matriarch of the ambrosia beetle colony is the sole egg-layer, while the other Insect Gifting 1 females care for the offspring.
