The ability of nitrogen fertilisers to break the lifecycle of gastro-intestinal nematodes
(Lincoln University, 2017)
Current gastrointestinal nematode (GIN) control relies heavily on chemical anthelmintic, targeting nematodes within the host ruminant. Most of the lifecycle occurs outside of the host so targeting the free-living population ...
A new pest management research facility: Scion’s large-scale precision track sprayer
(New Zealand Plant Protection Society (Inc), 2014)
A new large scale precision track sprayer has been developed and evaluated for spray deposition and pesticide application research under controlled conditions. The spray room is fitted with a 4 m wide electrically driven ...
Drift reducing potential of low drift nozzles with the use of spray-hoods
(The New Zealand Plant Protection Society Inc., 2014)
A field study was conducted in November 2013 to assess the drift reduction potential of a three headed spray-hood unit with either DG95-02 or DG95-015 low-drift nozzles used with the hoods either on or off (DG nozzles ...
Causes of elevated coumestrol in lucerne and mitigation of the subsequent risk to ewe reproductive performance
(Lincoln University, 2017)
Coumestrol in lucerne can reduce the ovulation rate of ewes, which lowers lambing rates. This thesis isolated the factors with potential to increase the coumestrol levels of lucerne. The management of ewes during the mating ...
Mitigating the effects of gastrointestinal nematode infection in organic lambs through the use of hospital paddocks
(Lincoln University, 2013)
This thesis investigated the use of a hospital paddock treatment comprised of chicory (Cichorium intybus), plantain (Plantago lanceolata) and red clover (Trifolium pratense) in place of anthelmintic treatment to provide a ...
Multiple perceptions of reality: a new lens for examining on-farm milk quality in New Zealand

The author discusses the arrival of organic certifier Certenz in the market and what it represents. Certenz is compared to Bio-Gro. Standards, marketing, profit focus and levy charging is conversed.
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 ...
Development of a phase-doppler technique for mass balance and spray characterisation of orchard air-blast sprayers within New Zealand horticultural cropping systems
(Lincoln University, 2017-05-09)
The knowledge of the sprays emitted from orchard air-blast sprayers has historically been assessed using an array of samplers to capture airborne particles such as various strings/ribbons, paper material, and/or patternation ...
