Environmental Influences on the Drying Rate of Spray Applied Disinfestants from Horticultural Production Surfaces Drying rates of disinfestants commonly applied to horticultural plant production surfaces were evaluated under cool to hot weather and under laboratory conditions to characterize the range of drying times and how this relates to contact times specified on product labels. Drying rates of six disinfes... Environmental Influences on the Evaporation Rate of Horticultural Disinfestants The evaporation rate of disinfestants when sprayed on production surfaces is expected to vary under different weather conditions but it is unknown how that affects efficacy. This study is an initial investigation into how the evaporation rates of water and six commercial disinfestants that contain a... UVC (254 nm) and Far UVC (222 nm) irradiation affects in vitro growth of Colletotrichum sp. isolates and their infection of detached strawberry leaves. Various alternatives are being developed to reduce or replace chemicals for plant disease control. We conducted laboratory studies to evaluate the effect of conventional UVC (245 nm) or FarUVC (222 nm) irradiation on growth of strawberry anthracnose pathogens in culture and on the disease response f... Genomic and transcriptomic comparisons of the twig blight pathogen, Passalora sequoiae with Mycosphaereallaceae foliar and conifer pathogens Passalora sequoiae is a foliar pathogen to conifer tree species. In this study, we conducted whole genome and transcriptome analyses on isolates of P. sequoiae collected from symptomatic Leyland Cypress leaves from a Christmas tree farm in Mississippi. The objectives for this research were to elucid... Efficacy of Peroxygen Disinfestants Against Fungal Plant Pathogens: A Systemic Review and Meta-Analysis. Peroxygen compounds, such as hydrogen peroxide, peracetic acid and potassium peroxymonosulfate, have been used as disinfestants in agricultural and horticultural operations for about 30 years. This systematic review was performed to investigate overall efficacy of peroxygen compounds against fungal ... Complete genome sequence resource for pseudomonas amygdali pv. loropetali strain AAC causing bacterial gall of loropetalum chinense Pseudomonas amygdali pv. loropetali is the casual agent of bacterial gall disease on Loropetalum. Here, we report the complete genome of P. amygdali pv. loropetali AAC, which represents the first whole genome sequence of the pathovar loropetali. Strain AAC was found to have one circular chromosome ... A Systematic Review and Quantitative Synthesis of the Efficacy of Quaternary Ammonium Compounds Disinfectants Against Fungal Plant Pathogens Quaternary ammonium compounds (QACs) have been used as disinfestants in plant production systems since the later-twentieth century. In studies on the control of fungal pathogens in agricultural and horticultural crop production systems, the efficacy of QAC disinfestants is variable, ranging from ver... Disinfestants This chapter provides a comprehensive up-to-date summary on commercially available disinfestants for the control of plant pathogens in woody ornamental nurseries. Information in this chapter is provided to help producers in horticultural settings select a suitable disinfesting product for different ... Sanitation: Disease Control from Start to Finish This chapter provides a comprehensive up-to-date summary of how to implement sanitation practices in woody ornamental nurseries. Nursery sanitation is an assortment of practices to reduce and potentially eliminate plant pathogens at identified point sources within production facilities. Sanitation i... Comparative performance of sanitizers in managing plant-to-plant transfer and postharvest infection of Calonectria pseudonaviculata and Pseudonectria foliicola on Boxwood Calonectria pseudonaviculata and Pseudonectria foliicola causing infamous ‘boxwood blight’ and ‘Volutella blight’, respectively, are constantly threatening the boxwood production and cut boxwood greenery market. Both pathogens often cause significant economic loss to all parties (growers-retailer) i... Efficacy of Hypochlorite in Disinfesting Nonfungal Plant Pathogens in Agricultural and Horticultural Plant Production: A Meta-Analysis Bleach products containing hypochlorite are commonly used as disinfestants to eliminate non-fungal plant pathogens such as bacteria, oomycetes, and viruses, from production surfaces, plant surfaces, irrigation water, and produce dump tanks. While these products are useful, their effectiveness has be... Draft genome assembly of Passalora sequoiae a needle blight pathogen on leyland cypress Objectives: Passalora sequoiae (family Mycosphaerellaceae) causes a twig blight on Leyland cypress that requires numerous fungicide applications annually to minimize economic losses to both the ornamental plant nursery and Christmas tree producers. The objective was to generate a high-quality draft ... Eliminating the loropetalum knot bacterium from stainless steel, pressure-treated wood and loropetalum stem surfaces Bacterial gall is a relatively new disease problem on Loropetalum cultivars in commercial plant nurseries. Currently, few products have been tested for their efficacy to kill the bacterial pathogen, Pseudomonas amygdali pv. loropetali. Several commercial disinfestants were tested on stainless steel,... Efficacy of peroxygen disinfestants against non-fungal plant pathogens in agricultural and horticultural production: A systematic review and meta-analysis. Peroxygen compounds, such as hydrogen peroxide (HPX) and peracetic acid (PAA), have only been used to disinfest surfaces of plant pathogens in the last 30 years. A systematic review was performed to evaluate overall efficacy of peroxygen compounds specifically against plant pathogens in agricultural... Control of Pseudomonas amygdali pv. loropetali on metal, wood, and Loropetalum chinense stem surfaces Clorox® Germicidal Bleach, Cuproxat®, Green Shield® II, KleenGrow™, Virkon® S and ZeroTol® 2.0 were evaluated for their ability to inactivate Pseudomonas amygdali pv. loropetali on stainless steel (SS), pressure-treated wood (PtW), and Loropetalum stem sections. Clorox® at 11% product and Virkon® S ... A Systematic Review and Quantitative Synthesis of the Efficacy of Quaternary Ammonium Compounds in Disinfesting Nonfungal Plant Pathogens Quaternary ammonium compounds (QACs) have been used as disinfestants to inactivate plant pathogens on tools, equipment, production surfaces and harvested produce surfaces in plant production systems since the mid-twentieth century. A systematic review was performed to evaluate overall efficacy of QA... Efficacy of hypochlorite as a disinfestant against fungal pathogens in agricultural and horticultural plant production: a systematic review and meta-analysis Hypochlorite is often used as a disinfestant of fungal pathogens in agricultural and horticultural settings. However, reports of its effectiveness are variable across studies. A meta-analysis was conducted to assess the efficacy of hypochlorite against fungal pathogens and explore factors that expla... Monthly Levels and Criteria Considerations of Nutrient, pH, Alkalinity and Ionic Variables in Runoff Containment Basins in Ornamental Plant Nurseries Triplicate water samples were collected monthly from 9 waterways (8 runoff containment basins (RCBs) and 1 stream) on 4 commercial ornamental plant nurseries from February to July, and from 1 RCB and nursery from April to October. Four RCBs, one per nursery, were actively utilized as an irrigation w... Meta-analysis of chlorine usage as a disinfestant in plant production Chlorine has a long history of usage as a disinfestant to inactivate plant pathogens on tools, equipment, production surfaces and harvested produce surfaces in plant production systems. The main active ingredient of many commercial chlorine sanitizers is sodium hypochlorite, which has been used at r... Monthly levels and criteria considerations of nutrient, pH, slkalinity and ionic Variables in runoff containment basins in ornamental plant nurseries Triplicate water samples were collected monthly from 9 waterways (8 recycling containment basins (RCBs) and 1 stream) on 4 commercial ornamental plant nurseries from February to July, and from 1 RCB and nursery from April to October.
