Impacts of Different Pentachloronitrobenzene (Quintozene) Use Patterns on Severity of Damping-off of Ginseng (Panax quinquefolius) Caused by Rhizoctonia solani
Journal of Ginseng Research, 2002Co-Authors: Reeleder, CapellAbstract:In replicated field trials, the efficacy of pentachloronitrobenzene (PCNB; Quintozene) for control of damping-off of ginseng seedlings was found to be affected by timing of application and formulation. Application at the time of seeding and prior to placement of straw mulch was found to provide the moat consistent level of disease control. However, decline in plant stand during the four-year production cycle resulted in most treatments providing similar levels of plant populations at harvest. Soil residues of pentachloronitrobenzene were generally highest (1 PCNB/g soil) in those treatments that exhibited the highest levels of disease control in the seedling year. Straw contained high levels of Quintozene after application. Beet seed assays with artificially-infested soils indicated that current use rates provide an amount of product suitable for high levels of disease control.

Multiresidue method using SPME for the determination of various pesticides with different volatility in confined atmospheres
Analytical and Bioanalytical Chemistry, 2004Co-Authors: Federico Ferrari, Astrid Sanusi, Maurice Millet, Michel MonturyAbstract:An analytical method is described for assessing the vapour concentration of 11 pesticides (bioallethrin, chlorpyriphos methyl, folpet, malathion, procymidone, Quintozene, chlorothalonil, fonofos, penconazole and trimethacarb) in confined atmospheres (e.g. a greenhouse after pesticide application). This study is a successful extension of a method previously developed by the authors for dichlorvos to much less volatile pesticides. Sampling was performed by using polydimethylsiloxane–solid phase micro-extraction (PDMS–SPME) fibres immersed in a 250-mL sampling flask through which air samples were dynamically pumped from the analysed atmosphere. After a 40-min sampling duration, samples were analysed by GC/MS.

Laboratory and field evaluation of fungicides for the management of sugarcane smut caused by Sporisorium scitamineum in seedcane
Australasian Plant Pathology, 2012Co-Authors: Shamsul A. Bhuiyan, Barry J. Croft, Rebecca S. JamesAbstract:Sugarcane smut caused by Sporisorium scitamineum is one of the most devastating diseases of sugarcane. Two trialzole fungicides, propiconazole and triadimefon, have been used to protect seedcane from infection with sugarcane smut elsewhere, particularly after hot water treatment. These fungicides were registered under an emergency permit in Australia when smut was found for the first time in Queensland in 2006. A research program was initiated to screen and evaluate a range of fungicides against sugarcane smut. Nine fungicides were tested in vitro at various concentrations for their efficacy on smut spore germination. Azoxystrobin (Amistar®), Quintozene (Quintozene® 750) and didecyl dimethyl ammonium chloride (Steri-max®) completely stopped germination of teliospores at 2.5 mg a.i./L. Propiconazole (Tilt®), triadimefon (Bayleton®), cyproconazole (Alto®) and acibenzolar-s-methyl (Bion®) significantly ( P

Propiconazole (Tilt®), triadimefon (Bayleton®), cyproconazole (Alto®) and acibenzolar-s-methyl (Bion®) significantly (P < 0.05) reduced spore germination at 50, 100 and 200 mg a.i./L. Two field trials were planted in spring 2008 and autumn 2009, where cane setts that had been inoculated with smut were dipped in a range of fungicide suspensions for five or 10 min, prior to planting. Cyproconazole, propiconazole, triadimefon and azoxystrobin significantly (P < 0.05) suppressed disease expression for up to 6 months in a summer experiment and 9 months in an autumn experiment. These results have important implication for selecting new fungicides for the control of sugarcane smut in seedcane that is provided to Australian sugarcane growers as a disease-free propagation source.
