In 2018 I received some images on my cell phone. These images were of red crown rot, a soybean disease I had encountered while I was the field crop pathologist at the University of Delaware. The images clearly showed distinctive brick red, pinhead sized “balls” aggregated on the lower stems of the plant. My immediate response to the individual who sent the images was “That’s red crown rot (RCR)- It’s typically a non-issue and routinely found in... Read More →

What is IPM?
April 11, 2020
In modern production agriculture, it’s important that we look at the big picture of how to manage yield-robbing pests. It’s human nature to gravitate toward the practices that are either cheapest or the easiest. However, in the long run these selected practices may end up costing more. We must evaluate the short- and long-term impact of the decisions we make. IPM, or integrated pest management, consists of a host of tools that are available to properly protect a crop.
Integrated Pest Management: A sustainable approach that combines the use of prevention, avoidance, monitoring and suppression strategies in a way that minimizes economic, health and environmental risks.
1. Properly Identify the problematic pest:
a. Type of pest: Insect, disease, vegetation
b. What is the Life Cycle?
i. Larva stage or reproductive stage
ii. Active or over wintering
iii. Which cycle will cause the most damage?
c. Monitoring the Pest:
i. What is the density of the pest: Low-med-high or medium with aggressive potential?
ii. Economic Threshold: Pest density at which control measures should be taken to avoid crop value loss.
iii. Economic Injury Level: The lowest pest density that can reduce crop values equivalent to the cost of controlling the pest population.
2. Types of Treatments:
a. Crop rotation: Removing a susceptible host
b. Planting dates: Not exposing seed to pests with early planting in cool or wet soils
c. Chemical treatment: Seed treatments, residual and post herbicides, fungicide
VT (Corn)/R3-R4 (Soybeans).
VT (Corn)/R3-R4 (Soybeans).
d. Cover crops: Minimize winter annuals
e. Residue management: Minimizes insect and disease overwintering
f. Fertility: A fully fed crop will grower stronger and faster
3. Risk of Treatments:
a. Future resistance (insect, disease, weeds)
i. Over-application of same active ingredient and single MOA/SOA
b. Short-term results: Will it last long enough?
c. Cost: Will the cost of treatment produce a ROI?
d. Applicator and environmental risk: Personal risk, leaching, runoff, off target damage
