Aphanomyces Root Rot in Peas.

What Causes Root Rot in Peas?

Root rot of peas in the Canadian prairies has been a growing concern over the last several years.  While root rot can be caused by a number of organisms including Fusarium, Rhizoctonia, and Pythium, Aphanomyces has garnered the most attention as the new kid on the block.  First confirmed in Saskatchewan in 2012, then Alberta in 2013, it now appears that the pathogen is much more widespread (about 45% of Alberta fields in 2014), suggesting that it has been present for several years.  Aphanomyces euteiches

What Causes Clubroot in Canola?

Clubroot in canola is caused by Plasmodiophora brassicae, a parasite that infects the roots of host plants and produces club-shaped galls that restrict the flow of water and nutrients. Plasmodiophora brassicae is an obligate parasite, meaning it cannot survive without a living host.

What is a Fungal Screen™ for Cereals?

The Fungal Screen™ is a test that identifies potentially devastating seed-born pathogens that may be present on cereal seed (Please note: True Loose Smut requires a separate test.  Please click here to learn more.)

This is, perhaps, one of the most valuable diagnostic tools available to growers. It was developed by and is exclusive to 20/20 Seed Labs Inc.

Fusarium Tests and How to Use Them

Fusarium head blight (FHB) is well established in Ontario, Manitoba and Eastern Saskatchewan grain crops. Also called scab, this disease has now moved into western Saskatchewan and parts of Alberta as well. Alberta has a Fusarium graminearium management plan which defines a prevention and control strategy.  FHB is caused by Fusarium graminearum, a fungus that produces a mycotoxin called deoxynivalenol (DON), also known as vomitoxin.

3 Critical Seed Tests

What are “The 3 Critical Seed Tests”?

A germination test is an integral part of a seed quality regime and is vital for assessing seed viability. Beyond germination, we at 20/20 Seed Labs Inc. consider the 3 critical seed tests to be a vigour test, a thousand kernel weight test and a disease diagnostic profile to assess the range of seed borne diseases that may be present on the seed.

What is a Vigour Test?

What is a vigour test?

A vigour test reveals a seed lot’s ability to withstand a variety of different stress factors. 

Vigour tests are designed to mimic poor seeding conditions to find out how the seed lot will perform under stress. It’s the exact opposite of a germination test, where seed is grown under optimum conditions.

Nodulation Assessments

A healthy-looking pulse plant in the field is not necessarily a reflection of healthy nitrogen fixation underground. Localized soil environments, particularly those with variations in soil nitrogen, can lead to vigorous growth that can hide any nodulation problems.

A plant’s potential to fix nitrogen can be evaluated by assessing nodulation and plant growth characteristics. It means the only way to see if a rhizobia-based inoculant is helping the crop properly fix nitrogen is to dig plants up and examine the roots.

What is a Germination Test?

A germination test determines the maximum germination potential, or viability, of the seed.

Why do a Germination Test?

The germination rate of a particular seed lot is a key indicator as to how that seed will perform in the field.
