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.

The Effect of Foliage-applied Fungicides on Peas
Date 2017-03-20 10:17:13
Pea crop can be attacked by a range of a leaf, pod, stem and root diseases. There are some that are well recognised as causing severe damage, such as bacterial blight caused by the Pseudomon syringae complex and Phanomyces root rot. However, there are many others that are very common on pea crop such as downy mildew, powdery mildew, the Ascochyta leaf and stem disease complex and Septoria leaf blight that appear to affect crops. There is little evidence as to the actual amount of infection by the diseases that will lead to an economic yield or quality loss.
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
Assessment of 12 Herbicide Treatments on the Crop Tolerance and Yield of Bounty Peas
Date 2017-03-16 15:16:48
Peas are an important part of the arable crop rotation allowing a break between traditional cereal crops helping break disease and weed cycles. Weed control in these crops can have a large impact on yield especially when crops are sown in the spring coinciding with the germination of a large number of weed seeds.

Control of weeds not only helps maximise yield but it also prevents potential harvest difficulties due to the high moisture content of weeds retaining moisture in the crop and therefore requiring desiccation prior to harvest. Crop quality can also be affected due to water staining on seed peas as well as the difficulty of removing some weed seeds from the harvested crop, this is especially so for Californian thistle (Cirsium arvense) infestations in processed pea crops.

The present trial was designed to evaluate the effect of 12 herbicide treatments on the yield of both processing and seed peas.
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.
Improved pea production for sustainable arable farming: pea crop monitoring report 2006-07
Date 2016-08-16 15:02:56
This report covers one of the projects carried out as part of the Pea Industry Development Group’s programme to identify management practices to improve productivity, reliability and profitability of pea production. This particular project monitored 30 pea paddocks in the 2006-07 growing season to try to identify the principal management and environmental causes of plant establishment yield variability. The variation in emergence within paddocks, and between adjacent rows within paddocks, was considerable. However, this study was not able to isolate the factors that determine why establishment is so poor and variable.
