Crop report May 27

Precipitation of 3.5 inches in April plus additional 7 inches in May are both blessing and obstacle for farmers SW Nebraska.

Wheat

Both dryland and irrigated wheat is heading and in good condition with soil moisture ranging from 20-40% of allowable soil water depletion. To my knowledge, there is no stripe rust in wheat fields but fungicide treatment is recommended to protect the flag leaf from stripe rust, Fusarium Head Blight (scab) or other infestation that may occur if temperatures increase in following weeks. Fungicide treatments for wheat can be found here.

Corn

Corn planting is 80% done and most of the fields are at V1 stage or emerging. Emerged corn looks chlorotic due to cloudy weather and little sunshine available in past week. Some seedling diseases are present. Rooting black tissue is observed above growing point, so there is no need for drastic measures at this point. Fields are muddy and in cases where weeds are growing out of optimal herbicide applications (6 inches and higher), timely areal applications might be both efficient and economical.

Ideal time to control kochia with residual pre-mix preemergence hearbicides (Lumax, Lexar, Acuron, Fulltime NXT, etc.) that can be mixed with burndown or selective post-emergence herbicide for season long kochia control (dicamba and glyphosate based products).

Other crops and pastures

Soybean planting started on irrigated acres and is about 20% done. Grain sorghum planting is close to being done on irrigated and is just getting starting on dryland acers. Field peas and potatoes that got planted in March and April are loving current growing conditions (see pictures). Early season grazing started on the pastures, beautiful sight!
