Will It Pay? Understanding the Disease Triangle Can Help You Make Fungicide Decisions

    • Start scouting for foliar diseases in corn just before tassel emergence
    • Determine if all 3 legs of the disease triangle are present by answering these questions:
      • What was the previous crop?
      • What has the weather been like?
      • Does the field have a history of disease?
      • What is the resistance level of the hybrid?

Corn Decision Guide

Adult Corn Rootworm Management Critical for Pollination Success & Population Control

  • Corn rootworm (CRW) silk feeding causes economic losses when not identified timely and properly controlled
  • Properly timed foliar insecticide applications are highly effective in managing adult CRW to protect pollination and manage future populations
  • DuPont Pioneer and university research has shown that yellow sticky traps are an easy, convenient and reliable method for estimating corn rootworm populations within a corn field

Evaluating Corn Pollination Success

Evaluating Your Corn’s Pollination Success

  • The number of kernels set per ear is determined near the time of pollination
  • Pollen shed (anthesis) is controlled by a combination of genetic and environmental factors
  • Pollination stress susceptible period extends from 1 week prior to silking to approximately 2 weeks after silking
  • Multiple environmental factors can affect silk growth and pollination, including drought, intensive heat and insect silk clipping

Soybean Reproductive Stages R1-R2

Understanding Soybean Reproductive Growth Stages and Scouting Tips

  • Identifying the correct growth stage of your soybeans is important for many in-season decisions
  • In-season herbicide applications are commonly limited by reproductive stages R1-R3, depending on the individual herbicide label
  • Understanding what pests to scout for at each reproductive stage will allow most economical return of in-season crop protection applications

Timing Fungicide Application

Get Fungicide Application Timing Right

Fungicide application timing is critical for protecting yield potential. Scout regularly to time applications for best control of gray leaf spot, southern rust, frogeye leaf spot, cercospora blight and leaf spot, and other diseases. Choose a fungicide that moves quickly into and throughout the plant.
