Use of the systemic fungicide propiconazole for oak wilt management: an assessment of uncharacterized host - pathogen - fungicide interactions.
Propiconazole is a systemic fungicide widely used for the control of oak wilt, however, the long-term efficacy of this fungicide has not been well established and treatment effectiveness may be below levels that justify its use in many situations. To date, it is not known if propiconazole …

Intensive management of barley in Saskatchewan
… ethephon (0 and 0.24 kg ha-1) and two levels of propiconazole (0 and 0.125 kg ha-1). Varieties used in ICM tests were Bonanza, Samson, Leduc, Virden, Johnston and Heartland. The second experiment, comprised of nine tests, compared two PGRs (ethephon and ethephon + CCC) at two rates and two stages …

Evaluating Fungicide Timing for Leaf Spot Diseases of Wheat and Fungicide Resistance in Pyrenophora tritici-repentis
… or demethylation inhibitors (DMI) like propiconazole. It is therefore imperative to limit the amount of fungicide applied to fields to reduce the exposure to pathogens that may lead to insensitivity. The objective of this project was to evaluate the efficacy of applying synthetic …

Epidemiological Studies of Northern Corn Leaf Blight on Corn Inbreds: Loss Assessment and Disease Modeling
… methods and the efficacy of a new fungicide, propiconazole, for NCLB control were also investigated. Data from these studies were used to develop a simulation model to help students conceptualize disease effects on corn yields and management effects on disease and yields. In three inbreds …

Effects of an insecticide/fungicide mixture on queen rearing behavior and hypopharyngeal gland morphology in honey bees (Apis mellifera L.) (Hymenoptera: Apidae)
… chlorantraniliprole and the triazole fungicide propiconazole for pest management during bloom. Although this mix is considered safe for honey bees, I investigated possible sublethal effects on the nursing behavior and hypopharyngeal gland morphology of one-week-old nurse bees. For one week I fed …
