Three questions with tips and links to adjust combine settings for tough evening threshing, to reduce grain loss and manage residue.

1. The Combine Optimization Tool at canolacalculator.ca walks you through adjustments to fix harvest problems – including grain loss, grain sample quality and productivity. The tool notes, “A grain sample that _______ is usually associated with high grain loss and/or low productivity.” (Fill in the blank.)

has high dockage

is too clean

has a lot of broken seeds

includes unthreshed pods

2. Combine settings for a warm, sunny afternoon may not be ideal for a cool, dewy evening. In a Canola Digest article, Marcel Kringe says the increase in canola seed loss out the back of the combine as conditions change throughout the day can ___________. (Fill in the blank.)

surprise you

be ignored

make it not worthwhile to combine at night

easily be two to three bushels per acre

3. Leaving longer stubble (and putting less material through the combine) is one way to improve residue spread and improve combine productivity. What is the general rule on stubble height?

Cut at a height equal to or less than the seeding tool’s row spacing

Half the residue as stubble, half through the combine

Adjust height based on harvest conditions

Let the harrows take care of the residue

Three questions on big weeds at harvest and the seed bank risk. What is the harvest strategy for drowned-out areas with a lot of weeds?

Four photo questions on interesting things found while scouting canola crops across the Prairies this week.

Timing is critical for pre-harvest sprays, and the safe staging (for canola yield and quality) might be later than you think. Here are three questions to test your spray staging knowledge.

Pre-harvest products and how to use them

Five photos of interesting and unusual finds in fields and farms this week. Are they all pests?

Nothing obscure about these three images. Here are symptoms from three big yield robbers doing their thing in canola fields this week. We tossed in a few other choices to make the quiz just a tad more challenging.

No, this is not a quiz about “Video Killed The Radio Star” but you might want that three-minute late 1970s diversion before tackling our five questions about insects of the week.

Six questions to help you with bertha armyworm scouting, including where, when and how to count, and how many worms is too many.

Canola crops are teeming with life! Most of the creatures simply live out their lives, not doing any economic damage. Some are beneficials, in that they pollinate crops or parasitize insect pests. A small few are pests. Here are different canola crop dwellers we don’t often talk about in Canola Watch. There are seven answers and seven photos…a true mix and match. Have fun!
