Canola Crop Looks Good in North Texas and Southern Oklahoma- Hanging On Further North
Fri, 06 Feb 2015 12:08:18 CST
The following Canola Crop overview is provided by Heath Sanders with the Great Plains Canola Association
Crop Conditions:
North TX: Water is standing in terraces, stands looked good, canola plants were green and healthy, even the no-till canola looks excellent.
Southern OK: Canola Plants had greened up, moisture was adequate, and stands looked good. Late planted or emerged canola didn't look as good, but don't count it out yet.
Central OK: Some plant green-up, canola stands look good, drier soil conditions, especially driving north.
Northern OK and Southern KS: Dry soil conditions, very little plant tissue green-up, canola plant stands have thinned, but most stands remain acceptable for the potential of a good crop, Late planted or emerged canola is struggling, but should not be neglected or abandoned. Varietal differences can be seen.
Insect Concerns-
Diamondback Moth Larva and Army cutworms were found in fields that did not receive a fall post application if insecticide.
Fields that did receive a treatment were free of insects at this point in time.
Diamondback Moth Larva Thresholds have not yet been determined. However, Heath Sanders he has found ~2-4 per plant and recommends spraying.
Army cutworm threshold is 1-2 per foot of row Heath says of the Army cutworm- Very hard to find, colors blend with soil. Look around the crowns of plants and in the soil and producers need to be aware that they are nocturnal and aggressive eaters
Sanders says that he strongly advises growers who have not sprayed an insecticide this fall to scout their fields and get the crop sprayed.
Canola Stand Evaluation-
Winter canola stands have thinned out down the row in some areas of the region, with the thinning leaving the fields from 10-50% of plants. Sanders says that fields still have enough plants for a good crop. Sanders believes that a winter canola stand doesn't necessarily have to be thick, a plant stand of <2 plants per square foot can still produce a respectable yield.
Canola Topdressing-
Reference soil test analysis with the amount pounds of Nitrogen applied in the fall to meet yield goal.
2.5lbs of Nitrogen per bushel, (ex. A 40 bu/ac yield goal will take 100 units of N)
Recommend 10-20lbs/ac of Sulfur (preferably in in the sulfate form)
