Does Applying Fungicide to Corn Pay? (08/01/13)

We have received a number of calls recently about the use of fungicides, post-tasseling on corn. Fungicide use in corn has been growing in importance in the USA. Fungicides can be an effective tool for controlling diseases, if genetic resistance is inadequate and when disease pressure is high. In North Dakota it is difficult to find foliar diseases on corn.

Corn Development Concerns 2013 (08/01/13)

The recent cool and dry weather has introduced new concerns for this season’s corn crop. Following one of the coldest Aprils on record and wet soils that delayed planting, the actual median planting date for corn of mid-May turned out to be very similar to the date when most of the corn is planted. Corn planting obviously was given priority over other crops whose range in planting dates was much wider than that of corn.

Managing Water (08/01/13)

Although the 2013 mid-summer period is relatively dry, many parts of North Dakota experienced wet conditions during the first half of the growing season. One method to alleviate excess water in the soil is via water management through subsurface drainage. Producers have many questions and some of the more common questions will be addressed in this article.

Insecticide Control of Sunflower Head Insects (08/01/13)

Chemical treatment is directed at the larval stage of the banded sunflower moth, which is the actual damaging stage. The 2013 economic threshold for the Banded sunflower moth is only one moth per 100 plants due to the high market value of oilseed sunflowers. Please see the article on “Sunflower Insects Emerging” in the Crop & Pest Report #10, July 11, 2013 for more details on banded sunflower moth thresholds.
