Plant Protection Chemistry NZ Ltd



Our Research

Our research focuses on formulation efficacy and aims to provide agrichemical users with improvements to their spray programmes, which also reduce the environmental impacts of herbicide and pesticide sprays. As an independent company we provide national and international clients with confidential and tailored projects; these range from laboratory-based, through use of controlled environment and tracksprayer facilities, to field-scale projects.

R & D for end-users, such as farmers and growers
PPCNZ undertakes research to improve the targeting of pests, diseases and weeds in horticulture, agriculture and forestry. Our spray application and tank formulation research is used to enhance pesticide control, reduce off-target spray drift, minimise pesticide use, and to increase the profitability, productivity, crop quality and efficiency of spray operations for growers. We provide research, technical advice and guidance to a wide range of grower groups and individual growers in New Zealand, on how to improve their spray programmes.   > Read more

R & D for specialty agrichemical providers
PPCNZ undertakes a wide variety of laboratory tests to measure and compare the performance of adjuvants and spray formulations, on a variety of plant species. Much of this confidential work contributes to the development of novel agrichemical adjuvants and innovative uses for existing products, and provides data for numerous patent applications by our clients.   > Read more

Fundamental R & D
How do agrichemical sprays applied to plants work? Their biological efficacy is related to the amount of spray retained by the plant, the area of foliage covered by the spray and/or how much active ingredient (AI) enters the plant (uptake) and moves (translocates) inside the plant to the site of biological action. PPCNZ is heavily involved in research to clarify the mechanisms involved in each of these processes and to model them. This fundamental research provides valuable IP to underpin all our application research.   > Read more
