Winter Weed Control Workshop: Surfactant - Importance in Today’s Tank Mixes

Author: Joe Bolte

Over the last few years, we've focused on honing in on the Liberty/glyphosate and the tank-mix combo, including things like proper coverage, spray tips. This year, we've also started running surfactants.

Winter Weed Control Workshop: Liberty® + gly Nozzle+ Carrier Rate

Author: Joe Bolte

This PFR study is designed to evaluate Liberty and glyphosate and their carrier rates. Why is this important? Because one is a contact and one’s systematic herbicide, their coverage requirements are different.

Winter Weed Control Workshop: Success with Liberty® and Liberty® + Glyphosate

Author: Joe Bolte

Going into 2021, a lot of the trait platforms available have Liberty in them. Liberty is a great product that can help control those glyphosate-resistant weeds we've struggled with the past few years.

Agronomy Talk: SPRAYER SETUP

Author: Alex Long

All sprayers have common elements, regardless of make or type. Every sprayer includes a tank, pump, boom, and nozzles. Things like flow rate, boom width, and pressure all impact your gallons per acre (GPA) when making applications. This document will help you work through all the formulas so you can make necessary applications at the rate you desire.

Agronomy Talk: SOIL pH AND LIMING

Author: Ben Wiegmann

Soil is comprised of organic matter, minerals, water, air, and organisms on the Earth’s surface that enable farmers to plant, manage, and harvest high-yielding crops every year. Soil is the medium that allows seeds to germinate, emerge, take root, and develop into plants. Productive soil has appropriate soil tilth, drainage, microbial activity, and nutrient availability to support plant growth.

AGRONOMY TALK: FOLIAR FUNGICIDES IN CORN

Author: Chad Kalaher

Data from Beck’s Practical Farm Research (PFR)® studies show that there are several multiple mode of action (MOA) fungicides, that when applied at VT/R1, have provided a positive return on investment (ROI). When applying a fungicide, farmers not only expect to protect their crop from yield-robbing leaf diseases but also to improve late-season standability by reducing stalk rot infection and maximizing harvestability.

AGRONOMY TALK: FLOPPY CORN/ROOTLESS CORN SYNDROME

Author: Ben Puestow

Floppy corn syndrome is a root development issue that can occur between the V4 to V8 growth stages. This syndrome results in plants “flopping” or tipping over for a period of time and may lead to yield loss if the plants don’t recover. Interestingly, the plant usually shows visual signs before the physical tipping of the plants.

AGRONOMY TALK: FALL BURNDOWN CONSIDERATIONS

Author: Austin Scott

Utilizing a broad-spectrum fall (post-harvest) burndown can help reduce the soil weed seed bank by controlling winter annual and perennial weeds. It can also offer several auxiliary benefits to row crop fields. Beyond the goal of reliable weed control, a fall herbicide application has many benefits. It can reduce host plants for pathogens such as soybean cyst nematode (SCN), over-wintering insects, and even diseases in warmer climates, and it can help maintain soil moisture in drought-stressed/arid climates. Fall herbicide applications also enable fields to be planted as soon as weather conditions allow; and help soil warming and drying in the spring, especially no-till fields. The net result is a more uniform crop emergence with fewer abiotic and biotic stressors.

WEED MANAGEMENT BRIEF: NON-GMO CONTROL OPTIONS

Author: Joe Bolte

To be successful in non-GMO soybeans fields, especially those with weeds resistant to multiple herbicides, apply the same management principles as GMO soybeans. These principles become more critical with non-GMO soybeans because rescue options are much more limited.

WEED MANAGEMENT BRIEF: ALTERNATIVE POST-EMERGE HERBICIDE OPTIONS

Author: Joe Bolte

There are many effective post-emerge herbicide options available, but what happens if the soybeans are beyond the growth stage at which Liberty® can be applied? Depending on the trait platform, once we reach the R1 growth stage, soybeans must be managed like a glyphosate-tolerant soybean.

WEED MANAGEMENT BRIEF: Enlist Carrier Rate

Author: Joe Bolte

Enlist One® or Enlist Duo® 2,4-D choline are both very effective on glyphosate-resistant (GR) marestail, giant ragweed, and waterhemp. Just like glyphosate, Enlist One is a systemic herbicide, meaning coverage is not as crucial as it is with a contact herbicide. One approved tank-mix partner for Enlist One is Liberty®. The addition of Liberty provides two effective SOAs for GR marestail, giant ragweed, and waterhemp. When spraying Liberty alone, Beck’s Practical Farm Research (PFR)® data has shown a 12% increase in control when using a carrier volume of 20 GPA vs. 15 GPA.

WEED MANAGEMENT BRIEF: ENLIST — POST-EMERGENCE

Author: Joe Bolte

Enlist One® + Liberty® is very effective when it comes to glyphosate-resistant (GR) broadleaf weeds, especially in high-pressure scenarios. However, there may be other weeds, like grasses, that you are trying to control.

Agronomy Talk: SOYBEAN RUST

Author: Shane Carver

Soybean rust, (Phakopsora pachyrhizi), a serious disease of soybean and other legumes, was first discovered in the continental U.S. (Louisiana) in 2004. This disease has been reported to cause upwards of 80 percent yield loss when present under optimal, conducive conditions. Current soybean varieties grown have little to no resistance to soybean rust, thus making proper identification and management decisions even more crucial, as we begin/continue harvest in our area.
