Crops show significant improvement

Crops throughout much of South Parkland continued to show a significant improvement as a result of the warmer and drier weather experienced over this past week. Temperatures in particular have been ideal for crops that are now well into the critical reproductive stage of their development. Although the potential for well above average yields has been lost due to the excess moisture and flooded acres those who continued to manage disease may very well be rewarded with at least long term average yield potential.

Wheat Midge Update

Since we have now surpassed the 700 GDD throughout much of South Parkland the emergence of the female wheat midge has now likely begun. At 450 growing degree days the wheat midge emerge from their cocoon, with male wheat midge emerging after 660 growing degree days and females at approximately  700 growing degree days using a base 5 degrees C for the start of the accumulation. At 700 GDD we can expect 10% of females will have emerged, at 775-800 GDD 50% emergence and at 875-900 GDD over 90% emergence.  Given this increasing population of female midge, any wheat crops heading over the next 7-10 days maybe at risk to wheat midge. Most wheat is only susceptible to wheat midge from the time heads are first visible until the anthers are visible. Once the wheat has flowered then it is no longer susceptible to wheat midge. Degree days can also be using to estimate the emergence of Macroglenes penetrans, the main parasitoid of wheat midge. There should be greater than 90% emergence of Macroglenes penetrans at peak emergence of the female wheat midge so the parasitoids will be ready and waiting.

Foot Rot and Brown Girdling Root Rot in Canola

Foot rot and Brown Girdling Root Rot or BGRR is being seen in many canola fields throughout much of South Parkland. Symptoms of BGRR are rusty brown lesions on the canola tap root, which may girdle and pinch off the root if severe. If you see dying plants that are pinching off at the soil surface or plants with lower leaves dying off then you may have BGRR.  Foot rot may also cause a similar infection and is caused by both Fusarium and Rhizoctonia species. Fusarium foot rots may have an orangy pink spore mass at the soil line. Rhizoctonia foot rot may extend to a few centimeters above the soil line. 

Fusarium Head Blight Risk Map Update

The entire province continues to be at a low to moderate risk for fusarium development. FHB infection is favored by extended periods of high moisture, high relative humidity (>90%) and moderately warm temperatures (between 15 to 30°C/ 59 to 86°F). Although we have warmed up our humidity levels have dropped significantly. It is important to note that these maps are produced daily and can change dramatically from day to day as humidity levels change.

Cereal Leaf Beetle Moving into South Parkland

The adult cereal leaf beetles have shiny bluish-black wing-covers with the thorax and legs being a light orange-brown. Adult beetles overwinter in and along the margins of grain fields in straw stubble, and in the crevices of tree bark. They emerge in the spring once temperature reaches 10-15ºC and are active for about 6 weeks. They usually begin feeding on grasses, then move into winter cereals and later into spring cereals. Egg laying begins about 14 days after the emergence of the adults. Eggs are laid singly or in pairs along the mid vein on the upper side of the leaf and are cylindrical, and yellowish in colour. Eggs darken to black just before hatching. The larvae hatch in about 7 days and feed for about 3 weeks, passing through 4 growth stages or instars. The head and legs are brownish-black; the body is yellowish. Larvae are usually covered with a secretion of mucus and fecal material, giving them a shiny black, wet appearance. When the larva completes its growth, it drops to the ground and pupates in the soil. The pupal stage lasts 2 - 3 weeks after which adult beetles emerge and feed for a couple of weeks before seeking overwintering sites.

Recently we have found some minor cereal leaf beetle feeding in the Russell/Inglis area. In order to monitor the movement of this insect and to help prevent a more severe infestation MAFRD will introduce a parasitoid for the cereal leaf beetle. If you see indications of feeding feel free to contact your local MAFRD Go office for further investigation.
