IS MY CROP TOO STRESSED FOR HERBICIDE APPLICATION?

‘Is my crop too stressed for herbicide application?’ has been a common question this week. As mentioned in an earlier post, recent wet weather has coincided with the window for post-emergent herbicide application in many crops. The ability of a crop to ‘tolerate’ a herbicide application depends on its capability to metabolize or compartmentalize the […]

What are these “eggs” on cereal heads in my field?

Quite a few people over the past week have sent in photos (as in Figure 1 below) asking what are these “eggs” on the cereal heads, and noticing that they can be quite abundant in some fields. These are not eggs, but are the pupal cases of parasitic wasps. These are being found in fields that contained armyworms, and it is likely that armyworms were hosts for the parasitoids. For some parasitoids it is common for dozens of parasitoid larvae […]

Seeing Tall Plants in Your Semi-Dwarf Wheat?

Originally published July 24, 2015 If the differences in height are sporadic throughout the field, i.e. the odd plant here and there, it is probably one of three things causing these ‘tall-types’: a result if seed of another variety was inadvertently comingled with the variety you think you have (through cleaning of equipment, bins, harvest, […]

Fall Fertilizer Decisions Based on Soil Temperatures

    Growers should be monitoring soil temperatures to guide fall nitrogen management.  Provincial weather station soil temperatures are posted at: http://www.gov.mb.ca/agriculture/weather/soil-temperature.html The principle of fall fertilization is generally to delay applications until soils have cooled so microbial activity is curtailed.  That way less of the stable ammonium form-N (NH4+,) that is held on clay […]

White heads in wheat, could it be wheat stem maggot?

The following information is available in the Manitoba Insect and Disease Update for the week of July 27th & posted at: http://www.gov.mb.ca/agriculture/crops/seasonal-reports/insect-report-archive/insect-update-2015-07-28.html White heads of wheat (Figure 1) are noticeable in some fields of wheat that should otherwise have green heads still. One possible cause of this is wheat stem maggot.  If wheat stem maggot is […]

Frost Prior to Physiological Maturity in Corn

When frost occurs in the early fall before corn has reached physiological maturity (black layer), there is always concern about impact to yields and quality. The stage of crop, minimum temperature reached, relative humidity and duration of cool temperatures all contribute to the impact frost will have on the crop. Generally speaking, a light frost is considered below 0 but above […]

Question

Economics & Agronomics – Crop Management Decisions Need Both!

It’s an obvious statement to say successful farm management decisions need both agronomic and economic considerations. Farmers weigh out input cost versus the benefit to yield and quality of grain before making the decisions to buy and use new or additional products.  Agronomy and economic crop management goes much beyond inputs. Consideration of crop rotation, […]
