Organic Fertility Programs Impacting IPM Programs
2
How Can Your Organic Fertility Program Affect
IPM? Type of Organic Fetilizer And Chemcial
Composition Application Timing And Crop Or Pest
Response Examples 1. Nitrogen Source (soft
bodied pests) 2. Timing
of Application (root maggots)
3
Nitrogen Source And The Effects On Soft Bodied
Pests And Plant Disease Lessons Learned In The
Green Revolution And With Organic Fertility
Programs Insect and disease pressure is
effected by Nitrogen Fertilizer Excess N In
Unbalanced Applications (N-P-K) Increases pest
pressure, fecundity, lowers plant resistance
4
What Is Going On With Sucking Insects?
These Insects Process Sap For Food, More Nitrate
Is Better Food!
5
? Why Would We Care About Nitrogen Type ?
Nitrogen N is generally the most difficult
nutrient to manage organically because release
rates vary, the N cost is high and losses can
occur. We Usually Have Balanced Urea,
Ammoniacal and Nitrate N ?
6
How Can Your Organic Fertility Program Affect
IPM? CONCLUSION Type of Organic Fetilizer
And Chemcial Composition Can Have An Effect On
Pest And Disease Pressure Avoid High
Application Rates Of Nitrate N Balanced
Organic Products Require Mineralization And Are
Slower Release Nitrogen!
7
How Can Timing of Organic Fertilizer Application
Program Affect IPM? Example Anthomyiiadae
Flies (root maggots) Early season pests of many
crops, controlled in conventional crops with
pesticides at planting. Flies are attracted to
organic matter and germinating seeds maggots eat
roots and seeds!
8
Example Anthomyiiadae Flies (root maggots) Three
or more generations of SCM Day Degree
Analysis (daily highdaily low/2) -
39F. Gen.1 200 (most synchronized egg laying)
Gen. 2 600
Gen. 3 1000 ? What Happens If We Apply Dry
Organic Fertilizer At Gen. 1?

How Can Your Organic Fertility Program Affect
IPM? CONCLUSIONS Applicatiion Timing Can
Create A Huge Problem! For This Example Avoid
Dry Fertilizer At SCM Genation 1 Use An
Irrigation-applied Liquid Fertilzer Use Existing
IPM Programs (monitoring) Good Luck!!!!!
