THE 1ST TRIFOLIATE IS THE BEST TIME TO ROLL SOYBEANS Land rolling helps conserve moisture, levels the soil, and pushes small rocks into the ground. Some producers roll immediately after planting, while others wait until the soybeans have emerged. Rolling immediately after planting provides improved seed-to-soil contact and reduces the likelihood of plant injury. But, it also increases the chance of soil crusting, which hinders emergence. HERBICIDE INJURY SCENARIOS IN CORN Below is an overview of herbicide injury scenarios presented at the SouthWest Crop Diagnostic Days .

CONTROLLING COMMON BURDOCK Effective control of common burdock doesn’t happen overnight and is most successful when you can control new seedlings in the spring followed by controlling any larger first year plants in the fall so that they don’t overwinter, flower and disperse new seed the following year . Common burdock (Arctium minus) is a biennial that reproduces only by seed. POST PLANT NITROGEN APPLICATIONS IN CORN Fields that usually get nitrogen applied prior to planting and incorporated may have been planted this year without any nitrogen in order to speed up the process.

Corn Nitrogen Status Nitrogen mineralization is favoured by warm soil temperatures with adequate soil moisture and aeration. Excess moisture can slow mineralization or increase the potential for losses through denitrification (especially under warm conditions) or leaching. Spring of 2021 progressed similar to 2020. Sunshine and little rainfall resulted in great soil conditions through April NATIONWIDE MONITORING PILOT PROJECT FOR EUROPEAN CORN The European corn borer (ECB; Ostrinia nubilalis), has been an important pest of corn and other crops in eastern Canada for nearly a century now but is also known to be a sporadic pest in western Canada.Despite its name, ECB is actually a generalist feeder, having a wide range of hosts.Although corn is one of its preferred hosts, after decades of Bt corn use across Canada, ECB populations were AGRONOMY GUIDE FOR FIELD CROPS The first rule of corn planting is to plant into moisture (25%–50% or near field capacity). However, a few other considerations allow for some fine-tuning of planting depth. Shallow planting of corn (less than 3 cm (1.2 in.) deep), even into moisture, may lead to less favourable positioning of the growing point and first nodal roots.This may

Especially given one of the main reasons we no longer deal with soybean aphids IS IT TOO COLD TO PLANT SOYBEANS? Prolonged cold weather this spring has led some producers to wonder if soybean planting should be delayed.

FROST INJURY IN SORGHUM SPECIES Caution! Members of the sorghum family – sorghum, sudangrass, and hybrid sorghum-sudangrass – contain dhurrin, a glucoside that breaks down to release hydrocyanic acid, also known as prussic acid (hydrogen cyanide, HCN). A sudden disruption of growth such as frost, drought or cutting, causes prussic acid to be released inside the plant at a morerapid rate.
CAUTION! SILO GAS AND NITRATE POISONING Rain events across the province have interrupted a dry spring. While the water is welcome, the 5-7 days after a rain that ends a severe dry period increases the risk of nitrates in forage crops!

SILAGE FERMENTATION PROBLEMS 4. Sweet Odour. This smell is likely high concentrations of ethanol produced by spoilage yeasts, mixed with acetic acid. Fermentation losses were likely high and this silage will be prone to heating and spoiling in the bunk. Desirable lactic acid has little smell. 5. SHOULD WE CUT HAY IN THE MORNING OR AFTERNOON? There is considerable interest in improving haylage quality by cutting in the early morning with wide swaths to speed wilting and then chopping it later the same day. Cornell University research shows this approach significantly improves fermentation and digestible energy. Even though sugars are at their minimimum when cut in the morning FIELD CROP NEWSABOUTARCHIVESAUTHORSTOOLS AND RESOURCESPEST MONITORING NETWORKAPPSFIELD CROP PRODUCTION PDFFIELD CROPS RESEARCH Photo credit: Dr. Tarlok Singh Sahota.

FROST INJURY IN SORGHUM SPECIES Caution! Members of the sorghum family – sorghum, sudangrass, and hybrid sorghum-sudangrass – contain dhurrin, a glucoside that breaks down to release hydrocyanic acid, also known as prussic acid (hydrogen cyanide, HCN). A sudden disruption of growth such as frost, drought or cutting, causes prussic acid to be released inside the plant at a morerapid rate.
PRE-HARVEST HERBICIDE TIMING IN SOYBEANS A pre-harvest herbicide treatment can make harvest more efficient when there are an unacceptable number of weeds in a soybean crop. Both conventional and glyphosate tolerant fields that are weedy can benefit from a pre-harvest herbicide. Drier plant matter will pass more easily through the combine, lowering seed losses and reducing seed staining INTRODUCING THE NEW ADULT CORN ROOTWORM TRAP NETWORK 2 Rootworm Trap Set Up and Monitoring 1) Four sticky traps per field will be placed in a transect (Fig. 1). 2) Place the 1st trap approximately 50 rows in from the fields’ edge (not in headlandrows).
IS IT TOO COLD TO PLANT SOYBEANS? Prolonged cold weather this spring has led some producers to wonder if soybean planting should be delayed. Over the next few days weather forecasters are even predicting a “polar vortex” with possible daytime highs of 3°C and nighttime temperatures of minus 3. Does this mean soybean planting should be delayed until things warm up? There isan old adage that
