An investigation of pre- and post-emergence rots of garden peas and the results of trials with five fungicidal dusts as pea seed protectants
In this thesis the results of laboratory and field investigations into the cause and control of pre- and post-emergence rots of garden peas (Pisum sativum) are presented. These investigations were conducted during 1937-1938 at Canterbury Agricultural College, Lincoln.

The role of genomic islands in virulence of Pectobacterium carotovorum subspecies brasiliensis on potatoes
… of this pathogen (e.g. genes encoding putative plant cell wall degrading enzymes, phytotoxins, secretion systems, sugar utilisation, etc.), yet only one was present exclusively in the P. atrosepticum and P. carotovorum subsp. brasiliensis isolates historically known to cause blackleg. This islet …

Understanding pasture performance: the interaction between perennial ryegrass and viruses
In New Zealand livestock-based agriculture is an essential component of the economy, and at the very core of the majority of livestock-based farming systems in New Zealand is a pasture comprised of perennial ryegrass (Lolium perenne L.). Therefore, the productivity and profitability of livestock …

A new approach for delivery of entomopathogenic fungi for plant protection against insect pests and plant diseases via maize seed : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… to associate with roots and aerial parts of the plant. The potential benefits from the plant-fungal association are as broad as nutrient acquisition, plant growth promotion, protection against biotic or abiotic factors and even increase of the induced defence response in the plant through …

Genetic diversity and pathogenicity of pea downy mildew (Peronospora viciae f. sp. pisi) in New Zealand : A thesis submitted in partial fulfilment of the requirements for the Degree of Master of Applied Science at Lincoln University
… regions pods were collected from infected plants from 7 sites across the North and South Islands of New Zealand in the 2018-2019 growing season. An examination of the partial ITS1, complete 5.8S and partial ITS2 region via sequencing and RFLP analysis did not indicate any genetic variation …

Ensemble models to assess the risk of exotic plant pathogens in a changing climate
… that attempt to model the climate suitability of plant pathogens before their arrival into a new area mainly rely on a single model projection. In this research, eleven species distribution models (in the form of three modelling approaches which include correlative and mechanistic models) were …
