Scout for Red Sunflower Seed Weevils
USAgNet - 08/16/2017
Minnesota's sunflower crop is reported 90% good to excellent. And sunflowers in Colorado look good too, with 63% reported in good to excellent condition. Meanwhile, Texas reports 20% of the sunflower crop there has been harvested, reports the National
Sunflower Association.
North Dakota has 69% of it crop blooming, ahead of the 5-year average of 58 percent. In South Dakota, 38 percent of the crop is blooming, just behind the 5-year average of 41.
Producers should continue to scout for red sunflower seed weevils, and banded sunflower moth in sunflowers until fields reach the R5.7 crop stage (70% of the head area has completed or is flowering). Field reports indicate that populations of red sunflower
seed weevil are high, average of 20-30 weevils per head in the southwest and south central parts of North Dakota. This is way above the economic threshold levels of 5-6 weevils per head for oilseed sunflowers and only 1 weevil per head for confection
sunflowers. For the latest information visit www.ag.ndsu.edu/cpr for the ND Crop & Pest Report.
And it's been dry month in central Kansas. Karl Esping, who farms near Lindsborg, says the last measurable rain came on June 20. Still, he says his full season high oleic sunflower crop looks good. They're in the bud stage now and he expects they'll start
blooming in the next 10 days. He says his double crop sunflowers, planted around July 1, could really use some rain.
