Seeding Peas: Establish a Strong Crop
Seeding Date Seed peas as early as possible from late April to early May for maximum yield potential. Peas are more tolerant to spring frosts than other crops because pea cotyledons remain underground. If frost injury occurs, new shoots will emerge from axillary buds that are protected under the soil surface. The minimum soil temperatures…

Phytophthora Root Rot in Soybeans
Phytophthora root rot (PRR) is a soil-borne root and stem disease of soybeans caused by Phytophthora sojae. Unlike other root rot pathogens, P. sojae may infect soybeans at any growth stage. P. sojae is an oomycete pathogen, also called a water mould, that may remain dormant in the soil for several years. Infection of plants…

Lupin Production Guidelines
Download as a PDF or read full content below. Lupins are an attractive alternative pulse crop option since they are excellent nitrogen (N) fixers, resistant to Aphanomyces root rot and have an upright growth habit with good standability. Markets for lupins are in development in Western Canada. They are rich in protein (35-40% protein), high…

Soybean Aphids – Keep Scouting!!
Soybeans are flowering and pod filling and we have had some reports of fields with increasing populations of soybean aphids although still under economic threshold levels. This means we need to keep scouting since our crop is most at risk while it’s building our yield. Soybeans are most vulnerable to yield loss during the R1…

Grasshoppers in Pulse Crops – Needs a Repeat Visit!!
When we published this information four weeks ago, we had not heard of any grasshopper defoliation concerns. We were just being proactive. But now we are getting reports of a few fields that had high enough defoliation levels due to grasshopper feeding to warrant control measures. Being that our crops are pod filling, this is…

Soybean Stem Diseases – Now Appearing in a Field Near You!
We are entering that time of year when soybean stem diseases become more noticeable which is also, not surprisingly, when they are having the greatest impact on yield. Let’s take a quick look at the diseases we are most concerned about right now in southern Manitoba. White Mold (Sclerotinia) White mould can cause 2-5 bu/ac…
