Current Fungicide Data  06/12/17 10:40:39 AM

 

In a down commodity market, a fungicide treatment is an easy one to cut out of your production budget when trying to reduce input costs. We know of no other way to answer this question than to look at historic data—with a little bit of common sense. We will collectively say that foliar fungicides are agronomically good. Are they economically good?

 

There are always questions in the market of whether foliar fungicides work, what fungicide works best, the longest, and at what is the best time of crop development to apply your fungicide investment in order to produce the greatest yield increase. This is a bit of a moving target mainly due to the amount of presence of the foliar diseases in corn. We normally talk about Gray Leaf Spot. In 2015 and 2014 for that matter, its impact was amplified with the presence Northern Corn Leaf blight and Southern Rust. Northern Corn Leaf blight is not new to our area. It affected more acres than “normal’ in 2014/2015. Is this due to genetic tolerances, weather conditions, and amount of disease inoculums present? The answer is YES.

 

The industry encourages you to consider applying fungicides with an in-furrow planting treatment, at V5, after hail (heaven forbid), and at VT/R1. We won’t argue that you have a yield potential increase every time a fungicide is applied. Which timing will provide an economic return for you is the question?

 

FUNGICIDES IN STARTERS?? The historic data from BASF for the past few year’s indicate a 4-6 bushel increase in yield if all you did was to use 3 oz/acre rate Headline EC along with your starter of choice. This was enough to get us curious, and so in 2013 we ran a 16 row wide check—1/4 mile long with and without Headline in-furrow combined with 5 gal of 6-24-6 + 1qt of 9% Zn chelate with 3.4 oz of Capture LFR and found a 44.2 bushel difference. Again, enough to get our attention but also question the validity of the results. In 2014 we had two treatments with and without Headline EC at 3 oz combined with 5 gal of Optistart Pro--9-18-6-2Sulfur 0.5 Zn-0.05 MNw Avail + 3.4 oz of Capture LFR and found a 12.3 bushel/acre difference. IN 2015— we had two treatments with and without Xanthion (BASF IN-FURROW FUNGICIDE) at 3.6 oz/acre combined with 5 gal of Optistart Pro--9-18-6-2Sulfur 0.5 Zn-0.05 MNw Avail + 3.4 oz of Capture LFR and found a 7.6 bushel/acre difference.   IN 2016— we went back to just one treatment timing (early) (BASF IN-FURROW FUNGICIDE) at 3.6 oz/acre combined with 5 gal of Optistart Pro--9-18-6-2Sulfur 0.5 Zn-0.05 MNw Avail + 3.4 oz of Capture LFR and found a 7.6 bushel/acre difference.

We realize that this is not replicated data and statistically has little merit at all due to the lack of replications. HOWEVER, it is hard to argue the results we have found to date. On a 2 year average--for a $10.50/acre in-furrow treatment cost of the Headline EC/Xanthion, we gained $9.95 bushels per acre. Selling the corn at $3.25/bushel, we grossed $32.33/acre and netted an additional $21.83 acre minus the treatment cost.

 

V5 applications—We have tried applications at the this time of development in the past and quite frankly have not seen much for a consistent response—regardless of treatment used. Maybe the timing/development of the disease was “out of sync” with the timed V5 treatment. We did this when we were also applying post-emergence herbicides as the labels would suggest and although there was some response, it was not enough to cover the cost of the treatment—at V5.

 

It is rarely argued that a VT/R1 application annually provides the MOST return on your investment. Keeping the top 1/3 of the crop canopy healthy and maintaining photosynthetic capabilities is beneficial in ways besides yield. It may have been referred to as a plant health initiative, but, we have noticed increased stalk strength, larger stalk girth, and a larger, stronger root system as an added benefit from foliar fungicide applications when comparing treated and untreated checks within fields. All of these things combined will usually increase yield. We always resource the un-biased data from the University of Nebraska as a reference and combine it with our results to form an opinion.

 

Historic Data--We have picked Quilt/Quilt Xcel as the example for this conversation as we have used these specific products the longest and have the most experience with them. This is not saying there are not equivalent products in the marketplace.

Quadris on Soybeans--Different story here as the data is somewhat less “consistently convincing” over the past 7 years—although the average still suggests that it is worth your budget considerations. The past 3 years it is obvious that the treatment was worth your investment.—the previous 5 demonstrated “erratic” results. —Quadris fungicide applications offers a preventative and curative active ingredients combined with Endigo insecticide applications over the past years have also provided another option for producers to control late season outbreaks of disease and insects. This combination provides control of Common Rust, Cercospora, and Brown Stem Rot as and also provides knockdown and residual control for Soybean Aphids as well as Bean Leaf Beetle. Even though we haven’t experienced a widespread outbreak of any one of these problem lately, the average results are still compelling enough to consider the applications. Below are the WBI results from the past 8 years which have produced an average of 6.73 bushel advantage with the application and a net dollar advantage of $38.31/Acre . The rates were as follows: 6 oz of Quadris + 3.5 ox of Endigo + 0.5 pt. of Between applied at the R3-R4 stage.
