Soybean Replicated Strip Trials You Can Still Do In 2013

Soybean Replicated Strip Trials You Can Still Do In 2013

Iowa On-Farm Network trials are open for any Iowa farmer who wishes to participate.

As soybean planting finally gets underway in Iowa for 2013, the Iowa On-Farm Network is reminding farmers there are several On-Farm Network replicated strip trials open for any Iowa farmer who wants to participate. Some of these are continuations of previous studies. Others are new this year. "Most are fairly simple to set up, and we have product available where additional inputs are needed," says Mick Lane, communications director for the network. These on-farm trials are a program sponsored by the Iowa Soybean Association.

Seed treatment trials

•    TagTeam LCO on Soybeans (Novozymes BioAg, Inc.) Trial protocol

WILL IT WORK ON YOUR FARM?: The purpose of the Iowa On-Farm Network is to help farmers compare products and practices in their farming operations, under their farming conditions. Most of the trials are strip trials in fields and are fairly simple to set up. The On-Farm Network is a program sponsored by the Iowa Soybean Association.

The company description of TagTeam calls it a "...MultiAction biofertility inoculant that delivers better access to soil and fertilizer phosphate, more fixed nitrogen, and the proven performance of LCO Promoter Technology." TagTeam LCO is applied as a seed treatment on soybeans with whatever commercial seed treatment that is being used.

•    Poncho/VOTiVO vs. Gaucho (Bayer CropScience) Trial protocol

This trial compares soybean yields with treated with Poncho/VOTiVO or Gaucho.  The company says it gives better protection against some insects over Gaucho and the addition of VOTiVO protects the roots from nematodes.

Biological trials

•   Ratchet on Soybeans (Novozymes BioAg, Inc.) Trial protocol

These are examples of the imagery used by ISA On-Farm Network staff in analyzing replicated strip trials. Both are from the same field in 2012, showing where a combination herbicide fungicide trial was conducted. Differences between strips can be seen in both the color image (above) and the color infrared image (below). Imagery and a complete report of trial findings, like this example, are part of all On-Farm Network trials.

Ratchet is a patented LCO (lipo-chitooligosaccharide) Promoter Technology, intended for foliar applications. The company says the LCO molecule enhances nutritional capabilities that drive the plants' natural growth processes, improving both plant health and crop performance. The On-Farm Network protocol requires that Ratchet to be applied at 4 ounces per acre at the V4 growth stage on soybean foliage. The product can be applied mixed with glyphosate or other postemergence herbicides.

•    Quantum VSC & Quantum Light on Soybeans Trial protocol

Quantum-VSC and Quantum-Light are biological soil and plant amendments used to enhance uptake and use of nutrients by treated plants.

Participants in this trial have two options:

    Program 1: First application around planting and second application at about V5 (can be combined with fungicide or postemergence herbicide application.)~~~PAGE_BREAK_HERE~~~

    Program 2 (for those who don't have time for two applications): Apply product at about V5 (with fungicide or post-emergence herbicide application.)

Crop protection trials

•    Sulfentrazone/ Flumioxazin vs. Glyphosate Only (DuPont Pioneer) Trial protocol       

First application at preplant or preemerge, followed by application at R3

In this trial, farmers will compare soy bean two-pass weed control programs in replicated strips alternating between 1) sulfentrazone/flumioxazin applied preplant or preemerge, with follow-up postemergence glyphosate and 2) a glyphosate-only program.

•    High Intensity (herbicide and fungicide) vs. Glyphosate Only (Monsanto) Trial protocol

First application Pre-Emerge followed by application at R3

This trial is similar to the weed control trial above, but with the addition of a fungicide to protect against diseases and help plants reach maximum yield potential.

•    Priaxor fungicide with and without Fastac insecticide (BASF) Trial protocol

Applied at R3

Priaxor is a combination of Xemium and Headline fungicides, said to deliver a more continuous protection from fungal diseases. In this trial, alternating strips will compare soybean yield with the fungicide alone and when combined with Fastac insecticide.

•    ProAct and Propiconazole (fungicide) vs. Headline (fungicide) vs. untreated (Arysta LifeScience) Trial protocol

Applied at R3

Company description of ProAct is a Plant Health Regulator based on Harp-N-TekTM, a proprietary harpin protein technology from Plant Health Care. When ProAct is applied to soybeans, the harpin protein active ingredient binds to harpin receptors on the plant. These receptors respond to harpin as if it were a pathogen, and this reaction initiates an "inside-out plant response" that turns on a plant's own intrinsic growth and stress-defense capabilities. This soybean yield trial will compare two different fungicide products against each other and against an untreated strip.

•    Custodia (fungicide) vs. Headline (fungicide) vs. untreated (MANA) Trial protocol

Applied at R3

Custodia is a combination of both strobilurin and triazole fungicide chemistry. This soybean trial will compare yields from the two different fungicides and an untreated strip.
