Overview!

Put ’er there. Treat your corn and beans with Stratego® YLD fungicide and treat yourself to higher yield potential. With its advanced technology, Stratego YLD delivers all-around plant coverage for proven disease control.!!Stratego YLD fungicide offers:!§ Advanced chemistry!§ Proven disease control !§  Increased yield potential!§ Outstanding fit for early season application in corn!!


Advanced Chemistry!

The advanced chemistry of Stratego YLD:!§ Provides two modes of action!§ Delivers preventive and curative protection!§ Supplies corn and soybean plants with a higher

degree of fungicidal protection!§ Provides up to 21 days of residual activity due to

its retention and redistribution properties!§ Keeps plants healthier with a broad spectrum of

protection by combining the latest triazole technology on the market paired with a leading strobilurin chemistry !


Advanced ChemistryTwo Modes of Action!

Triazole Component !§ Progressive movement in the leaf!§ Redistribution properties for

sustainable, long-lasting disease protection!

1d 4d 7d 14d

Strobilurin Component!§ Rapid protection of the whole leaf

through vapor phase distribution!§ Penetration and translaminar

distribution of the strobilurin complement the effect of the triazole!


Advanced ChemistryTwo Modes of Action

Combat Resistance Development!§  Fungicides are vital to the future of agriculture.!

§ Some pathogens have developed resistance to certain fungicides; further resistance development needs to be prevented. !

§ Applying fungicides with multiple modes of action, such as Stratego YLD, fights all important corn and soybean fungal diseases, even strobilurin-resistant frogeye leaf spot in soybeans.!

§ Recommended, size-appropriate application rates should be followed, as reduced rates can enhance the development of resistance.!!


Advanced ChemistryUnique Movement!

Stratego YLD offers progressive movement in the leaf and redistribution properties that provide sustainable, long-lasting disease protection:!§ Diffuses in and on the waxy surfaces of the plant!§ Protects plants with systemic transport in the tissue!§ Expands protection with movement in surface moisture!§ Unique characteristics allow Stratego YLD to move on

the outside of the plant, as well as inside the plant, expanding coverage to unsprayed areas !


Advanced ChemistryConvenient Formulation!

§ Easy handling, storage and mixing!§ No tendency to crystallize !§ Low Use Rate means less product to handle!§ Water-based SC formulation for easy

application!§ Compatible with most herbicides, insecticides

and adjuvants.!§ Example: Tankmix with Leverage® 360

insecticide on soybeans for convenience and efficiency of controlling key insects and key diseases with a single application.!


Proven Disease Control!

§ With its powerful triazole component, Stratego YLD is effective on a broad range of diseases in corn and soybeans.!

§ The broad-spectrum control offers greater yield potential and increases plants’ stress tolerance and harvestability.!


Proven Disease Control!

Stratego YLD even stops strobilurin-resistant frogeye leaf spot (Cercospora sojina) as seen in this Tennessee soybean field.!

Frogeye Leaf Spot (Cercospora sojina)


TREATED UNTREATED

Yield Bump!

Due to its proven disease control and improved stalk strength, research shows Stratego YLD has the potential to boost yields in corn (early season and tassel applications) and in soybeans. !


Fungicide Applications to Corn!

Two distinct application timings:!§ Early season!

§  Between growth stages V4 and V7!§  Stage determined by counting exposed leaf

collars!§  Same timing as with many herbicide applications!

§ At tassel !§  Between growth stages VT and R2!§  From when the last branches of the tassel emerge!


Early Season Application in Corn!

§ Get a head start on your yield bump. Adding an early treatment of Stratego YLD to your corn delivers:!

§  Improved stalk strength!§  Early season disease control !§  Higher yield potential!

§ When preceding a tassel application, get even higher yield potential than from a tassel spray alone.!


Early Season Application in Corn Critical Opportunity for the Plant!

Corn plants between the V4 and V7 growth stages are at a critical growth phase. !§ Leaf and ear shoot initiation are almost

complete.!§ The entire starch reserves from the seed

have now been consumed, leaving corn to pull in all of its own nutrients and resources for the first time. !

§ The crop is very susceptible to early season environmental stresses and diseases.!


§ Researchers observed improved stalk strength with Stratego YLD in relation to untreated checks in trials.!

Early Season Application in Corn Benefits in Applying!


Early Season Application in Corn Convenience in Applying!

§ Tankmix compatibility with many other crop protection products growers already typically apply early season, including Liberty® herbicide, Laudis® herbicide and glyphosate !

§ Lower rate range of 2 to 5 fl oz/A !§  Less biomass to protect!§  Improved coverage!

§ Sprays via ground rig are possible, providing application flexibility!§ Application between the V4 and V7 growth stages allows for more

complete plant coverage!


Early Season Application in Corn Convenience in Applying!

Coverage needed for early season vs. tassel corn!§ Given the size differences of

V5 vs. tassel corn plant, the concentration of active ingredient on the 5th leaf of a corn plant treated at V5 with 2 fl oz/A of Stratego YLD is over 40% higher than the ear leaf of a plant treated with 4 fl oz/A at VT.!



§ Broad-spectrum control of economically important diseases such as anthracnose leaf blight and eyespot.!

§ Stronger stalks with reduced risk of lodging and green snap for improved harvestability.!

§ Plants stay greener longer for an improved window of grain fill.!

§ Protects lower corn leaves and establishes a barrier against infection of higher leaves. !

§  Diseases that survive in the soil infect lower leaves first, and “work up the plant.”!


Tassel Application in Corn!

Goal: !§  Protect leaves close to the ear!§  Improve stalk integrity!§  Apply after the last branches of the

tassel emerge through blister!§  Use caution just prior to tassel!

§  Some adjuvants may injure the silks!

§  May cause “beer can” ears!§  Most applications made by air!

!


Treatment targets (R3 to R5)!§ Protect upper leaves from Cercospora sojina (frogeye leaf spot),

Asian soybean rust and Rhizoctonia spp. (aerial blight)!§ Protect seeds from Cercospora kikuchi (leaf blight / purple seed)!
