Poncho/Votivo and StrategoYLD Early Application
How Poncho/VOTiVO works
 Poncho/VOTiVO contains bacterial spores
that germinate when the seeds germinate.
 The bacteria create a living
barrier that grows with young
roots during the critical
stage of plant establishment.
 The bacteria compete
with nematodes for space
and food resources.
 As a result, fewer nematodes
reach the root surface,
and some even die from
lack of nutrients.

The Power of Poncho in Soybeans
 In soybeans it delivers with a per-seed application
rate for efficacy against more insects than Gaucho®
600.
• Early-season Aphids
• Over-Wintering Bean Leaf Beetle
• Seed Corn Maggot
• Grape Colaspis
• And other early season pests
 Promotes higher yields through a healthier root
system and a more vigorous and uniform crop.

What changed from Stratego?
 New chemistry
• Newest triazole chemistry for corn/soybean market
• Improved performance across a broader spectrum of diseases
• Active at much lower rates
• Strengths include anthracnose, rust, and white mold activity
• Replaces old, less active triazole
 More strobilurin
• 4 fl oz of Stratego YLD contains as much strobilurin as 12 fl oz of Stratego
• Promotes consistency
 New formulation
• Water-based SC formulation
• More concentrated than the old EC formulation
• Compatible with other products and adjuvants
 END RESULT
•
Better activity
•
Easier to use
•
Even healthier fields – even higher yields

When should fungicides be applied?
 Secondary timing between V4 and V7
 Corn plant at V4
•
Energy from kernel is depleted
•
Corn stressed as it becomes self-sufficient
 Corn plant at V5
•
Growing point emerges above ground
•
Tassel initiated
•
Number of kernel rows determined
 Corn plant at V6
•
Beginning of rapid internode elongation
•
Ear and leaf shoot initiation complete
Advantages of early application
 Protects lower leaves (including leaves in whorl)
 Establishes barrier for infection of middle and upper leaves
• Soil-borne diseases “work up the plant”
• Lower disease ratings with V5 and R2 sprays
 Improves stalk integrity
• Anthracnose can infect before tassel
• Protects carbohydrate in stalk
 Typically applied with ground application
 Often tankmixed with herbicide
 Rates may be lower
• Less biomass to protect
• Improved coverage
