Peas Research

Peas have a relatively short season and are a popular vegetable over the summer months. Most peas grown in New Zealand are eaten processed.

In 2015 the total tonnage grown was 66,500 tonnes and $84.8m FOB was exported.

Root Rot of Pea
Date 2017-03-16 16:11:43
Oomycete plant pathogens cause diseases on a wide range of vegetable crops in New Zealand. They are traditionally more difficult to control than non-Oomucetous fungi, as they are not susceptible to most conventional fungicides. Recently, a number of reports have emerged in the scientific literature pertaining to biological control of these fungi using microbial antagonists. We are investigating the potential for biological control of two Oomycete plant pathogens which are important in New Zealand; Aphanomyces root rot of pea, caused by Aphanomyces euteiches and damping-off of lettuce caused by Pythium ultimum
The Crop Tolerance of Peas to the Application of 6 Common Herbicide Treatments
Date 2017-03-16 14:28:58
A trial was conducted at Dromore, Mid Canterbury assessing the effect of six herbicide treatments on the yield and TR (tenderometer) of the give process pea (pisum sativum) cultivars Epic, Tere, Bolero, Durango and Prolific. The six herbicide treatments included Treflan 21/ha (400g/l Trifluralin) pre sow, Gardoprim 2 I/ha (500g/l Terbuthylazine) pre emerge and the post emergent applications of Sencor 350 g/ha (700 g/kg Metribuzin), pulsar 5 I/la (200g/L Bentazone + 200g/L MCPB) and Bladex 3I/ha (500g/l Cyanazine) as well as a hand weeded control plot.
Pea Management: Code of Best Practice
Date 2016-08-16 12:24:40
This Code of Best Practice has been prepared on behalf of the Pea Research Working Group by John Hampton (New Zealand Seed Technology Institute, Lincoln University), Derek Wilson (Crop and Food Research, Lincoln), David Harrison (Wrightson Seeds) and Adrian Russell (Plant Research (NZ) Ltd). This is a working document. It will be revised annually as investigations instigated by the Pea Research Working Group produce results.
Improved pea production for sustainable arable farming development of ascochyta blight epidemics year 3 results
Date 2016-07-22 16:20:53
This report outline the project “Epidemic development of ascochyta blight” which completes the third and last year of work in the MAF Sustainable Farming Fund (SFF) project “Improved pea production for sustainable arable farming”. The main conclusion from this trial was that the sowing date had a major influence on final yield; early sown crops (August) had greater yields than later-sown crops (sown in September and October).
Field evaluations of effect of seed fungicide treatment on seedling establishment
Date 2016-07-22 16:20:52
This report outlines the project “Epidemic development of ascochyta blight”, which completes the third and last year of work in the MAF Sustainable Farming Fund project “improved pea production for sustainable arable farming”. Based on the findings we recommend that fungicide seed treatments should continue to be routinely used for peas because they provide worthwhile insurance against soilborne seedling diseases that can harm seedling establishment, and provide some protection against epidemics of downy mildew in young crops.
