Canola Watch 2022 exam – Section 2 – Canola Watch fundamentals

The Canola Watch 2022 annual exam for Certified Crop Advisors and Certified Crop Science Consultants (and anyone else who wants to enhance their agronomy skills) has five sections:

• Nutrient management (1 CEU – 0.5 in nutrient management and 0.5 in soil and water management)
• Canola Watch fundamentals (1 CEU – 0.5 in integrated pest management and 0.5 in crop management)
• Canola Watch podcasts (1 CEU – 0.5 in integrated pest management and 0.5 in crop management)

Section 2. Canola Watch fundamentals

This section has 10 questions from Canola Watch Fundamentals articles. These articles dig into best management practices for canola production and are a valuable resource for agronomy providers. 

Achieve a minimum score of 70 per cent (7 out of 10) to receive 1 continuing education credit (CEU) – o.5 in integrated pest management and 0.5 in crop management. CCA tracking number: SS 56465

7.  The article “Choose the right cultivar for each field” (Plant Establishment section) has a bottom line recommendation that each farm grow two or more canola cultivars each year. With two or more cultivars, performance can be compared and analyzed. What is it called when you analyze genetic performance based on local growing conditions?

Genomics

Genotyping

Phenotyping

Proteomics

8. The article “Broadcast seeding canola: Tips” (Plant Establishment section) has details on fertilizer application. If also broadcasting nitrogen, note that broadcast nitrogen has a higher risk of loss, especially when applied on very moist soils. What does the article recommend?

Apply in the fall ahead of a planned broadcast crop.

Choose ammonium sulphate as the right source.

Rely on soil nitrogen reserves for a broadcast crop.

Use urease and nitrification inhibitors.

9. Which one of the following is a correct statement from the article “Right rates for seed-placed fertilizer” (Fertility section)?

Anhydrous ammonia is the safest nitrogen source for seed-row placement.

Clay soils are riskier than sandy soils.

Potassium fertilizers have a low salt index and present minimal risk when placed in the seed row.

Safe rates will be even lower in fields with high pH soils.

10. The article “Factors in the sclerotinia spray decision “(Diseases section) lists factors that increase risk and decrease risk. This sentence is directly from the article: Risk is limited when current conditions are dry, max daily temps are _____°C or more, and this is forecast to continue for seven to 14 days. (Fill in the blank)

11. The article “Verticillium stripe - identification and management” (Diseases section) includes a scouting tip from Yixiao Wang. Wang discovered another way to distinguish verticillium from another common canola disease. What is the discovery?

Discolouration from verticillium extends farther up the stem than discolouration from blackleg.

Leaf lesions early in the season are more likely to be blackleg.

Stems infected with verticillium become solid and much more difficult to snap than sclerotinia-infected stems.

Verticillium microsclerotia have a sweeter taste than sclerotinia sclerotia.

12. The article “Agronomy: Steps to make an accurate diagnosis” (Diseases section) has a paragraph on herbicide history and the risk of herbicide carryover. What areas, according to the paragraph, present a “worst-case scenario for herbicide carryover”?

Corners

Headlands

Hilltops

Low-lying

13. The article “Lygus bugs – scouting, timing and thresholds” (Insects section) says a threshold of 20-30 per 10 sweeps is suitable for canola crops with good growing conditions. But you may not need to count all lygus in the sweep net. Some are not mature enough to do damage. It includes the photo below. What is the message for this photo?

Count both of them when scouting.

Don’t count the one on the left, it’s too young.

Don’t count the one on the left, it’s an aphid.

Don’t count the one on the right, it doesn’t cause damage.

14. The article “Integrated weed management: Best practices” (Weeds section) leads off with tips to make crops more competitive against weeds. Two practices that improve competition are higher seeding rates and taller crops. To make its point, the article includes a graph with results from a Neil Harker study in barley. Harker measured wild oat biomass for tall versus short barley and low versus high seeding rates. He also compared wild oat biomass for continuous barley versus barley in a rotation. Looking at results for continuous barley, short barley at the low seeding rate (200 per square metre) resulted in 4,530 kg/ha of wild oat biomass. What was the wild oat biomass in kg/ha for tall barley at the high seeding rate (400 per square metre)?

15. The article “Straight combining canola – tips” (Harvest and Storage section) has a paragraph on combine settings. Straight combined canola often requires combine settings different from swathed canola. The paragraph describes three settings to consider. Two are (1) to take wires out of the concave to release canola seeds faster, and (2) pull back the rotor vanes to keep crop inside the rotor for more rotations. What is the third?

Narrow the sieve settings.

Slow the ground speed.

Speed up the fan.

Speed up cylinder/rotor RPMs.

16. The article “How to reduce combine loss” (Harvest and Storage section) explains how to measure loss out the back of the combine. If losses are too high, farmers can take step to lower them (Step 3 in the article). The article provides a link to the Combine Optimization Tool. Click the link to find the tool. The tool first asks users, What harvesting problem are you having? What are the three choices?

Uneven crop, high seed moisture, green seed

Grain loss, grain sample quality and productivity

High dockage, broken seeds, poor crop feeding

Grinding rotor, header plugging, uneven residue discharge
