Elucidating Influence of Temperature and Environmental Stress on Turfgrass Response to Mesotrione and Evaluation of Potential Synergistic Admixtures to Improve Mesotrione Efficacy
Mesotrione is under evaluation for registration in turfgrass for weed control, but often requires repeat treatments. Previous research in agricultural crops indicates tank mixtures with mesotrione may improve weed control. Three field trials were conducted in 2005 and 2006 in Blacksburg, VA on …

Postemergence control of annual bluegrass with mesotrione in Kentucky bluegrass
… turfgrass species and lack adequate selectivity. Mesotrione is an herbicide with postemergence control of many broadleaf and grass weed species. An HPPD-inhibiting herbicide, mesotrione causes the destruction of plant tissues by increasing free radicals and reactive oxygen species through the …

Understanding the Interaction of Mesotrione and Atrazine in Redroot Pigweed (Amaranthus Retroflexus)
… an in-depth analysis on the interaction of mesotrione and atrazine and their impact on herbicide resistance stewardship and weed control efficacy. Mesotrione and atrazine are herbicides primarily used in corn, or maize. Herbicide resistance and a reduced number of new chemistries emerging to …

Physiological and Environmental Basis of Turfgrass and Weed Response to Mesotrione Formulations
Mesotrione is the first triketone herbicide registered for use in turfgrass. Triketones prevent carotenoid biosynthesis by inhibiting the enzyme p-hydroxyphenylpyruvate dioxygenase (HPPD). Although mesotrione controls many species of grass and broadleaf weeds, it is best know for selective control …

Weed management in conventional, no-till, and transgenic corn with mesotrione combinations and other herbicides
… (POST) for season-long weed control. Mesotrione is a new triketone herbicide registered for PRE and POST control of broadleaf weeds in corn. Triketone herbicides function through inhibition of the enzyme p-hydroxyphenylpyruvate dioxygenase. Mesotrione applied PRE did not adequately …

Distinct biochemical and molecular mechanisms confer resistance to mesotrione and atrazine in a multiple herbicide-resistant waterhemp population
… reported the first case of resistance to mesotrione and other 4-hydroxyphenylpyruvate dioxygenase (HPPD) herbicides in a waterhemp population designated MCR. Experiments were conducted to determine if target-site or non-target-site mechanisms confer mesotrione resistance in MCR. …

Eficiência dos herbicidas atrazine e mesotrione, em aplicações isoladas e em misturas, no controle de plantas daninhas na cultura do milho
… utilizado em mistura com o atrazine tem sido o mesotrione. Todavia, quando se misturam duas moléculas químicas que têm atividade biológica, estas podem interagirem promovendo efeitos antagônicos, sinérgicos ou aditivos sobre o organismo alvo. Diante disso, o objetivo desse trabalho foi conhecer …

Characterization of Acetolactate Synthase-Inhibiting Herbicide-Resistant Smooth Pigweed and Corn Weed Management Programs Utilizing Mesotrione in Combinations with Other Herbicides
… programs in corn (<i>Zea mays</i> L.) utilizing mesotrione, a triketone, in mixtures with other herbicides. ALS-inhibiting herbicide-resistant smooth pigweed biotypes were collected from fields in Virginia, Delaware, Maryland, and Pennsylvania to evaluate response to ALS-inhibiting herbicides and …

THE INFLUENCE OF CARRIER WATER QUALITY, COAPPLIED FOLIAR FERTILIZER, AND WATER CONDITIONING ADJUVANT ON HERBICIDE EFFICACY
… hydroxyphenylpyruvate dioxygenase (HPPD); or mesotrione, glufosinate, isoxaflutole (MGI) resistant soybeans are being developed which will allow the use of mesotrione herbicide. Gaining knowledge on effect of carrier water quality will help for optimizing spray solution for herbicide …

Studies on sweet corn: Stewart's wilt forecasting, the effect of maize dwarf mosaic on foliar diseases, and herbicide sensitivity
… yield following postemergence applications of mesotrione or nicosulfuron. Stewart’s disease can be forecasted using the Stevens, Stevens-Boewe, or Iowa State forecasts. These forecasts assume a high degree of host susceptibility. Host resistance affects the incidence and severity of disease, …

From the simple to the complex: an examination of different herbicide resistances
… non-target-site resistances, to atrazine and mesotrione, in a population of waterhemp (MCR). Crosses were performed to generate F1, backcross (BC), and F2 lines. Through separate atrazine and mesotrione dose responses experiments, it was determined that the responses of reciprocal F1 lines did …

Phenotypic and biochemical characterization of atrazine and HPPD-resistant waterhemp (amaranthus tuberculatus) populations
… both populations had been exposed to previously (mesotrione) and another that had not been applied to either population (isoxaflutole). A dose-response experiment was conducted in the greenhouse at two different postemergence (POST) timings. Overall our findings did not indicate a consistent …

Characterization of HPPD-inhibitor resistance in waterhemp (Amaranthus tuberculatus)
… to foliar applications of the HPPD inhibitors mesotrione, tembotrione, and topramezone. Furthermore, a mesotrione dose response comparing MCR with two known HPPD inhibitor-sensitive waterhemp populations revealed the level of resistance to be 10-to 35-fold. The efficacy of foliar-applied HPPD …

Imaging the distribution of agrochemicals in plants by MALDI-MSI.
… The agrochemicals of interest are azoxystrobin, mesotrione, fluazifop-p butyl and nicosulfuron. Azoxystrobin is a broad spectrum fungicide which inhibits mitochondrial respiration in fungi; the compound is absorbed through the roots and translocated in the xylem. Mesotrione is a selective phloem …
