Floriculture crops can lose their aesthetic quality due to water deficit during postproduction. Calcium is a secondary messenger in plant stress signaling, and the treatment of calcium has been proposed alleviate damage by various abiotic stresses. The objective this research was evaluate application methods delay wilting under deficiency three species bedding plants: viola (Viola cornuta), imp...

New Zealand agriculture utilises trace element supplements to protect livestock from fungal infection. For example Zinc (as zinc oxide) administered as an oral drench or intraruminal bolus, is used extensively to protect sheep and cattle from facial eczema. A large percentage of administered Zn is however excreted in faeces and there is published evidence to show that Zn levels in pastoral soil...

The efficacy of topical, leaf residue, and soil drench applications with Isaria fumosorosea blastospores (Ifr strain 3581) was assessed for the management of the citrus root weevil, Diaprepes abbreviatus (L.). Blastospores of Ifr were applied topically at a rate of 10⁷ blastospores mL-1 on both the larvae and adults, and each insect stage was incubated in rearing cups with artificial diet at 25...

Following on from our studies on the potential use of tannins to control intestinal parasites in small ruminants we recently conducted two further trials to investigate the effect of a wattle tannin oral drench (WT), or supplementation of the diet with acacia (AMS), on faecal egg counts (FEC) and worm burdens of growing tropical Black Head Persian (BHP) sheep with an experimental intestinal nem...

Dissipation and transformation of cyantraniliprole, a new diamide class insecticides, were investigated under greenhouse conditions, using snapdragon (Antirrhinum majus) as the model plant. cyantraniliprole in treated leaves was found to be dependent upon application methods (foliar spray versus soil drench) doses (high low dose), with parent insecticide being major residue at various sampling ...

Systemic insecticides and application methods were evaluated in two trials that began in 2005 and 2006 for control of potato leafhopper (Empoasca fabae [Harris]) on four red maple (Acer rubrum L.) cultivars and rated annually through 2007. Treatments evaluated in this study included surface drenches of imidacloprid plus cyfl uthrin (Discus) or imidacloprid plus bifenthrin (Allectus SC), clothia...

The hemlock woolly adelgid, Adelges tsugae Annand, is an invasive species reducing the populations of eastern hemlock, Tsuga canadensis L. Carrière, throughout the eastern United States. Systemic imidacloprid and horticultural oil are the primary chemicals used to control infestations of this invasive pest; however, the impact of these two chemicals on nontarget canopy insects is unknown. This ...

Effectiveness of a hot water drench for the control of Aphelenchoides fragariae infesting hosta (Hosta sp.) and ferns (Matteuccia pensylvanica) was studied. Drenching with hot water at 70 degrees C and 90 degrees C in October reduced (P < 0.05) A. fragariae in the soil but not in the leaves relative to the control (25 degrees C) 300 days after treatment (DAT). Plants drenched with 90 degrees C ...

The purpose of the study was to determine the efficacy of Enterisol Ileitis vaccine administered orally in water against porcine proliferative enteropathy. For a comparison, two administration protocols were used for the vaccination: individual oral drench or via drinking water accessible to the herd. The efficacy of the vaccine was studied on breeding, commercial, and fattening swine farms. As...

Plant parasitic nematodes cause significant damage and losses to vegetable crops. Control of plant parasitic nematodes with pesticides is often restricted due to their high toxicity and negative impact on the environment. The need for environmentally safe control strategies has increased interest in developing biological control measures. The objective of this research was to study the effect o...
