How long before my corn tassels and/or is at maturity?? Quick gauge that will get you close is to pull the whorl out on chest high or taller corn and unroll the leaves wrapped around the tassel. For each leaf there is about 2.5-3 days of growth depending on temperatures. So 4

I’ve had several weed ID ???s on Wild Parsnip. Reminder: The sap of wild parsnip contains a toxin that can cause a severe rash/blistering when it comes in contact with the skin and sunlight. Be careful! More info 🔗: crops.extension.iastate.edu/encyclopedia/w… #ISUCrops

More hail in the area the past several systems. Be sure to evaluate not just leaf area loss but also damage to stalks and more importantly developing ears. Many adjustors do not take this into consideration. We have seen in the past few seasons minor foliar damage has led to

As the humidity picks up and some rainfall has occurred in many spots, disease questions are popping up.. Latest from Corteva disease tracker..

Starting to see some tassels, silks and pollen flying. Pic taken at Pottebaum Crop Services, mid April planting and hybrid is P02405PCE. With all the sunshine, you can see the with the deep dark green color of this crop it is intoxicated with photosynthates!! Pollination

Happy Birthday America!!! From all of us at Pioneer..

As you prepare for corn fungicide season, be sure carrier pH levels are adjusted to recommended level of the product you are using. Fungicides are the most susceptible of all crop protection products to carrier pH. You are spending the $$ to apply a "full rate", be sure pH is

Spotting some CRW beetles.... Time to "beetle bomb"?? NO!!! I have seen to date only male Western CRW beetles (black back) and not seen any females (striped back). Target is 20% gravid (ready to lay eggs) females before an insecticide application is made. Females do not lay

Avoid Beer Butt Syndrome!! Reminder for those who be starting fungicide applications prior to tassel. Also the different emergence dates within fields this spring due to north vs south or east vs west side of hill has separation in growth stages. Applications of surfactants

An alert went out earlier this week on the Midwest Pest Alert Network that soybean gall midge has been confirmed in Tama and Poweshiek Counties. Keep an eye out for wilty or dying soybean along field edges! You can sign up for the pest alert network: pestalerts.extension.iastate.edu.

Fungicide decision time. I have struggled for the past 15 years scouting for disease at VT and making an accurate prediction of ROI for fungicide applications. It's nearly impossible. The issue is the "latent" period of corn disease. That is the time the infection takes place

Key part of winning the waterhemp battle??? Edge of field management! The non crop areas adjacent to the field have to be treated if the grass has been killed off as there is no competition/canopy and seed production will be in the billions and enter the field. Some areas it

Disease Prediction Model Update No surprise with the wet, warm humid weather that GLS and NCLB risk have increased dramatically. Chat with your local Pioneer Sales Representative about your genetic package and fungicide protection.

1st Western CRW female of the season!! This means "beetle bombing" or more properly known as adult management is around 14-18 days away as we want 20% of the females gravid... or ready to lay eggs. Adult management can be an effective component of a multi-prong approach to

Armyworm Alert! Numerous reports of armyworms along waterways and in alfalfa/hay fields. Be sure to check them out!!

Cooler weather on the way!! Everyone including our crops will enjoy the cooler weather. We know corn is driven by GDU's. The warmer it is the few days spent in grain fill, which means fewer days of converting solar radiation into sugars (ie YIELD). The forecast of cooler

Humid weather has corn diseases on the move. Today with talk with UNL plant pathologist Tamra Jackson-Ziems on timing and best practices. ⁦Pioneer Seeds U.S.⁩ ⁦Kevin Kowalski⁩ ⁦Kevin Keller⁩ ⁦Tamra Jackson-Ziems⁩ podcasts.apple.com/us/podcast/kic…

Sunshine.. on my shoulders... makes me happy!! Corn and soybeans love that old John Denver classic. Solar radiation is important in all stages, but none as important as blister and early milk stage. Even a healthy plant can abort a significant amount of kernels if there are

"Foliar symptoms alone are not enough to diagnose [sudden death syndrome]. It is important to inspect plants closely, dig and inspect roots, and split soybean stems open. After splitting stems, the pith of a plant infected with SDS will be white even if roots are severely

Does it make a difference to pull those few waterhemp plants sticking thru the beans? Check out pic from a customer visit this spring while checking corn stands. Customer said he saw about 20-30 plants in a clump in last years soybeans that got thru.. Didn't take the ten
