Factors affecting the response of thrips to an olfactory cue
(Lincoln University, 2013)
Some thrips (Order Thysanoptera) are key pests of many greenhouse and outdoor crops worldwide. Biological attributes such as polyphagy, rapid reproduction, cryptic behaviour and insecticide resistance make them particularly ...
Endophytes in maize (Zea mays) in New Zealand
(Lincoln University, 2017-08-24)
The aim of this study was to isolate fungal endophytes from maize in New Zealand (NZ) and to select endophytes with potential to reduce insect pests and/or plant diseases. Culture methods were used to isolate 322 isolates ...
Crop manipulation to improve hybrid radish seed yield and quality
(Lincoln University, 2018)
Hybrid radish (Raphanus sativus L.) seed is grown in New Zealand for multiplication and re-export, and radish seed exports were worth $22.8 million in 2017. Seed yields vary with hybrid and season, but are reduced by ...
Development of a tomato/root knot nematode bioassay to screen beneficial microbes
(New Zealand Plant Protection Society (Inc.), 2009)
In common with other root knot nematodes Meloidogyne hapla is a serious plant pest. A rapid screening system for candidate microbes that benefit plant growth is a first step to developing screening bioassays in ...
Pathogenicity of Gaeumannomyces graminis var. tritici increased by nitrogen applied to soil to enhance the decomposition rate of wheat residues
(New Zealand Plant Protection Society, 2016)
Soil cores removed after harvest of a wheat crop infected with the fungus,
Gaeumannomyces graminis var. tritici (Ggt), were amended with nitrogen and fungal saprophytes to increase decay of crop residues and subsequently ...
Exploring the impact of non-chemical methods on the control of bulb mite (Rhizoglyphus robini Claparède) and yield of saffron (Crocus sativus L.)
(New Zealand Plant Protection Society, 2018-07-26)
The bulb mite (Rhizoglyphus robini) causes damage to a number of crop and ornamental plant species, including saffron (Crocus sativus). A split-plot experiment based on a randomised complete-block design was conducted ...
Enhancing seed quality in the female spinach (Spinacia oleracea L.) parent line : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
Hybrid spinach (Spinacia oleraceae L.) seeds are produced in New Zealand for export. However, some seed lots fail to meet contracted germination standards. Several factors that may be responsible for seed germination and ...
Integrating the use of a beneficial fungus in the genus Trichoderma into the production of export onions (Allium cepa) in New Zealand : A thesis submitted in partial fulfilment of the requirements for the Degree of Master of Science at Lincoln University
(Lincoln University, 2019)
Trichoderma biocontrol products for use in onion crops are available in New Zealand but are not part of standard practice. Onion diseases and pests are largely controlled by current chemical pesticides but the export onion ...
Biological control of fusarium wilt of tomato by Trichoderma isolates
(New Zealand Plant Protection Society (Inc.), 2016)
This study investigated the ability of ten Trichoderma isolates to control the fusarium wilt pathogen of tomato, Fusarium oxysporum f. sp. lycopersici, as well as the effect of these isolates on tomato plant growth in the ...
A tale of two grass species: Temperature affects the symbiosis of a mutualistic Epichloë endophyte in both tall fescue and perennial ryegrass
(Frontiers Media SA, 2020-05-08)
Many cool-season grasses form permanent, mutualistic symbioses with asexual Epichloë endophytes. These fungal symbionts often perform a protective role within the association as many strains produce secondary metabolites ...
