We investigated whether pear (Pyrus communis L. OHF97) tree growth stage, nitrogen (N) status, wound age, and infection environment influences susceptibility to Phytophthora syringae Klebahn. Actively growing trees were sus- ceptible to the pathogen

Recent field observations by growers suggest that increased nitrogen (N) content in nursery trees resulting from foliar sprays with urea in the autumn increases tree susceptibility to infection by Phytophthora syringae. We investigated the effects of

Many nursery crops are susceptible to root and foliage diseases caused by numerous species of Phytophthora. Phytophthora ramorum causes sudden oak death of trees and ramorum leaf blight and shoot dieback on numerous nursery plants, including rhododen

Commercially available plant growth regulators (PGRs) or moisture retention gels, applied to the roots of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) before planting, can modify indole-3-acetic acid (IAA) levels in roots, root growth responses

We determined whether in vitro plant growth regulator production by mycorrhizal fungi is correlated with conifer seedling growth and root IAA concentrations. Container-grown seedlings of interior Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), lo

Bacteria isolated from Sri Lankan cowpea fields significantly reduced in vitro mycelial growth and sporangial production of Phytophthora vignae by producing agar-diffusable and volatile inhibitors. Bacterial volatile inhibitors were evolved when the

A growth chamber experiment was conducted to determine if P fertilization to enhance the P nutrition of otherwise N and P deficient Douglas fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings reduces water stress in the seedlings during drought peri
