This guide contains a list of fungicides labeled for use in South Dakota at the time of publication. The list is dynamic and prone to frequent changes. It therefore should not be considered as a substitute for label information. Always read and follow label directions for approved uses of these products, and check with the South Dakota Department of Agriculture for up-to-date product registration information.

According to the USDA 2007 Census of Agricul-ture, acreage in South Dakota treated with disease management chemicals has grown from around 41,000 acres in 2002 to nearly 800,000 acres in 2007, representing a nearly 2,000% increase in usage over just five years. For our major crops, fungicides are most effective as part of an integrated disease management strategy. Foliar fungicides alone are not the most effective means of preserving healthy plants. Well-adapted, disease-resistant varieties should always be used where possible and be combined with good cultural practices, such as crop rotation, disease-free seed, and optimal planting dates. Additionally, good crop scouting methods will help producers make sound decisions about when and where to apply fungicides as the need arises.

It is important to remember that fungicides are active only against fungi and do not directly protect against bacterial or viral diseases, nematodes, or abiotic stresses. And while there are many fungal diseases than can and do attack our crops, there are just a few that are routinely responsible for major economic losses. In corn and small-grain cereals, the residue-borne leaf spot fungi can be a problem during wet weather. For cereals, these diseases include mainly tan spot (caused by Pyrenophora tritici-repentis) and the Septoria/Stagonospora leaf spot complex. Another regularly occurring disease of wheat and barley is Fusarium head blight or scab (Fusarium graminearum), which can significantly affect both yield and grain quality. In corn, gray leaf spot (Cercospora zeae-maydis) can occur on susceptible hybrids; however, gray leaf spot has not been a major problem most years in

| agronomySouth Dakota. Other corn leaf blights (northern corn leaf blight, eyespot, or others) may also occur sporadically. Wheat leaf rust (Puccinia triticina) is a potential problem each year for small grain production; however, varieties with excellent resistance to the disease are available, which should reduce the need for fungicides in many cases. Various rusts (sunflower rust, common rust of corn, southern rust of corn, and others) may attack other South Dakota crops. Soybean rust (Phakopsora pachyrizi), which is a potentially destructive disease in some states, has not been detected in South Dakota (as of 2010). In general, soybeans have relatively minor foliar fungal problems in South Dakota; these fungal problems include brown spot (Septoria glycines), Cercospora leaf spot (Cercospora kikuchii), and frogeye leaf spot (Cercospora sojina).

The cost of fungicide management varies widely, depending on product and application method. Assuming ground-based application costs of around $5 per acre, the most commonly used products can be applied at recommended rates for around $15 to $30 per acre in most crops. Aerial application is generally a bit more costly. Prices may vary depending on the dealer and the local market conditions.

A Word About Resistance ManagementResistance to fungicides can develop in pathogen populations under certain conditions. When selection pressure is placed on

fungi through repeated application of a single product or class of products, the population may develop reduced sensitivity to those chemicals. This can happen very quickly if repeated applications are made in a single season. Strobilurin fungicides (see list below) seem to be especially prone to this effect, while triazoles have somewhat less risk of inducing resistance. The carbamate and organochlorine protectant fungicides have multi-site modes of action and much lower risk of resistance development. To reduce the risk of developing fungicide resistant pathogens, adopt a fungicide resistance management strategy, which may include the following practices:

• Apply fungicides only when necessary to prevent or treat fungal disease.

• Apply only at recommended rates.

• Use integrated management to reduce the number of applications necessary.

• Avoid repeated applications of the same product or mode-of-action to a single site.

• Use strobilurins only as preventatives.

• Strobilurins should represent no more than 30-50% of total number of applications to a site.

Commonly Used Fungicides Strobilurins (mode of action: respiration (QoI) inhibitors, FRAC Code 11):

azoxystrobin (Quadris; also a component of Quadris Opti, Quadris Top, Quilt, Quilt Xcel, Quadris Xtra,

Amistar); fluoxastrobin (Evito); pyraclostrobin (Headline; also a component of TwinLine, Headline AMP); trifloxystrobin (a component of Stratego, Stratego YLD)

Triazoles (mode of action: sterol biosynthesis inhibitors, FRAC Code 3):

propiconazole (Tilt, PropiMax EC, Bumper; also a component of Stratego, Quilt, Quilt Xcel); prothioconazole (Proline, also a component of Prosaro, Stratego YLD); tebuconazole (Orius, TebuStar, and others; a component of Prosaro); metconazole (Caramba; also a component of TwinLine, Headline AMP); myclobutanil (Laredo); tetraconazole (Domark); cyproconazole (Alto 100SC; component of Quadris Xtra); difenoconazole (Quadris Top)

Other fungicide groups (multi-site mode of action; FRAC codes M3, M5)

mancozeb (Dithane, Penncozeb); chlorothalonil (Bravo)

General Recommendations for Wheat and Other Small Grains Standard flag-leaf applications: The flag leaf (or uppermost leaf) of small-grain cereals is very important to achieving maximum production and grain quality, and we strive to protect the leaf with our standard fungicide applications to those crops. Diseases such as leaf rust and leaf spots can affect the productive leaf area if resistant varieties are not used and the


| agronomyweather favors pathogen infection and spread. This stage is reached when the ligule of the last (flag) leaf has emerged from the whorl. The triazoles and strobilurins as well as the premixed fungicide products are generally effective at managing these diseases. Refer to the most recent recommendation information from SDSU for more specific guidelines.

Flowering application for scab control: Fusarium head blight, or scab, occurs frequently in South Dakota, especially on spring grains in the more humid parts of the state. The pathogen infects the plant during and shortly after anthesis, or flowering pe-riod. When weather has been especially warm and wet during and prior to heading, scab can be a major problem. The triazole fungicides can be effective at limiting the disease impact if properly timed. For greatest efficacy, application should occur as the plant is actively flowering (when the anthers are yellow). For optimal control, producers should combine fungicides with scab-resistant varieties and should utilize a disease-forecasting tool such as the Fusarium Head Blight Risk Assessment Tool (found at www.wheatscab.psu.edu).

Early applications: In continuous wheat with standing stubble, an early application of fungicide is sometimes tank-mixed with post-emergent herbicides to prevent build-up of leaf diseases such as tan spot. These applications typically cost less than standard-timing applications (flag leaf or flowering) because they are generally applied at half the recommended rates and don’t

require a separate pass through the field. These applications may not be economical unless the above conditions (continuous crop, stubble, reduced rate, and tank-mixed with herbicide) are met; however, the reduced rates of early applications increase the risk of fungicide resistance in the pathogen population. Early applications of strobilurins fungicides should not be followed by flag-leaf applications containing the same mode of action.

General Recommendations for Row/Pulse Crops: Corn: Corn fungicide applications are often used to protect the plants during the stages from VT (tasseling) to R1 (silking). The major foliar diseases of corn are somewhat sporadic or less severe in South Dakota than in some neighboring states, and therefore fungicides should only be used when disease risk is high. High humidity or frequent rainfall situations are generally favorable for leaf diseases; however, many hybrids possess strong resistance to some of the major pathogens. To maximize the economic benefits of fungicides in corn, fungicides should be used when disease is present and at labeled rates at the proper timing. Use particular caution when considering application of fungicide during late vegetative stages prior to tasseling (V12-V14). Evidence suggests that certain tank-mix partners and some adjuvants have the potential to damage developing ears when applied at these stages.

Soybeans: Applications to soybeans are usually made in the early reproductive stages of the crop (R1-R5). Soybean fungicides are relatively new to South Dakota growers, having emerged largely in response to the threat of soybean rust. Apart from soybean rust, which has not been detected in South Dakota, there are relatively few foliar disease of soybean that are considered to be major production threats in this state. However, a number of very effective soybean fungicides are now labeled for use in South Dakota.

Oilseed crops: Fewer fungicide products are registered for sunflowers and safflower than for our other major crops; however, these crops occasionally experience severe disease outbreaks. Rust of sunflower is an emerging disease threat in the Northern Great Plains and can be controlled through resistance or a well-timed (early flowering) fungicide application. Safflower can be susceptible to Alternaria leaf blight in wet years, or under irrigation, though the disease can be effectively controlled with fungicide application at the first signs of infection.

Field Pea/Chickpea: Fungicides in these crops primarily target Ascochyta, a seed- and soil-borne fungus that can cause very damaging leaf and/or pod blights during wet years. Sound cultural practices should be used in combination with fungicides and include the following: resistant cultivars, delayed planting, disease-free seed, appropriate residue management, and extended crop rotations.
