Northeast Iowa
Crops are progressing very well in Northeast Iowa.  Click the video below for details.

Northwest Iowa
The crop looks great! Most of the corn in northwest Iowa is into 11 to 12-leaf stage; we’re seeing some tasseling in the 15 to 16-leaf stage. Fortunately, we’re not seeing any disease pressure. Soybeans are starting to bloom. Second crop alfalfa is also blooming, so cutting will begin soon. We received a 1/2-inch of rain Tuesday morning with more to come.

Central and Eastern Iowa
Corn throughout the area certainly made “Knee High by the Fourth.” The corn crop is in V9-V10 range and looks good in most areas. I had an opportunity to travel most of eastern Iowa last week and was very impressed with the corn crop between Highway 18 in the north to Highway 30 in the south. Producers are beginning to make plans for upcoming fungicide applications on this year’s crops. Crop rotations, hybrid/variety selection and past history should all be considered as we choose fields for applications. A little time working with your seed supplier and field agronomist can go a long way as we protect the yield on this year’s corn and soybean crop.

As for soybeans, this year’s crop continues to look good with excellent stands in most areas. Soybeans treated with SoyShield and SoyShield Plus have again shown an advantage in fields in the area. A scouting report along the Iowa River last week found aphids in very small populations. Everyone needs to keep an eye on insects and disease pressure in the weeks ahead.

Tasseling corn in Southeastern Nebraska

It was hot and sticky most of the week. We experienced light rain and fortunately no severe weather. We’re right at our historic average on heat units through the last week in June based on 30 years of compiled data.I did manage to find some tasseling corn in South Central Nebraska. With the tasseling, comes a number of diseases and fungi to look for when scouting: Gray Leaf Spot, Eyespot, Goss’ Wilt and Rust. Also make sure the corn plant is at brown silk and through pollination before application of fungicides. Many high concentrate crop oils and triazole chemistries can damage silks and pollen glumes.

North Central Iowa
Northern Iowa had another very good week for crop growth. Weather was warm and sunny with plenty of heat units to keep crops growing. Since the area received 1 to 2 inches of rain in the past week, soil moisture is in good shape despite the high heat.
Corn made huge gains this week is ranging from V7- to V10- stages. Latham® Hi-Tech Hybrids LH 5268 3000GT had a solid week again, even in corn-on-corn. This week I talked to several corn-on-corn growers and was reminded how important hybrid selection and management is for those acres. Having a strong agronomic hybrid like LH5268 is critical to preserving corn-on-corn yields. With fast emergence a strong defensive package, LH5268 looks exceptional this year, even in tough acres.
Soybeans are in the late stages of V to the R1 across the area. Soybeans have looked exceptional all year and this week continued that trend. With plenty of moisture and warmer temperatures, we’re seeing nice gains in soybean crops.
This week we’re expecting some showers with temps back in the 80s, so it should be another solid week.

Southeast North Dakota
Overall crop conditions are good. Corn and soybeans have been responding very well to the sunshine and warmer weather that we’ve received lately. Some of the more advanced corn is in the V8 stage. North Dakota Agriculture Weather Network (NDAWN) readings at Lisbon, ND have the GDD units for corn at 805, which is only 44 units behind normal. Considering how wet and cold the planting season began, things are going pretty good. Reports show about 6.5 million acres – or about 28% of the cropland acres – were not planted this year in North Dakota. Northwest ND was the hardest hit region with up to 80% not planted in some counties.

Southwest Iowa
Unfortunately, crops in the area were beat up last week from high winds. Soybeans are into early r1 stage. The corn has rebounded and is now at V7, V8 stages. Latham® Hi-Tech Hybrids LH 6396 3111 is looking great, and it handled high winds of 70 to 80 MPH. Latham® Hi-Tech Forage LH 9000, which was seeded this spring, produced 3.5 half bales an acre.
