Ag Innovations Seminar Charlie McKenna 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.
Poncho/VOTiVO in Action Poncho/VOTiVO on the left; UTC on the right. 2010 Iowa trial Poncho/VOTiVO on the left; UTC on the right. 2010 Indiana trial
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.
Poncho/VOTiVO in Action With Poncho/VOTiVO Without 2010 Ohio trial. 41 days after planting.
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
