NUTRITION MANAGEMENT FOR MITE INFESTATIONS A Webinar Hosted by AEA Featuring John Kempf
Mites are attracted to high levels of ammonium in plant sap.
Spider Mites on Corn
Plant sap at mite presence:
●Forage Foliar Blend ●SheaShield ●Rebound Manganese ●Rebound Zinc ●Rebound Iron Applied through pivot
This image shows dead spider mites on the corn after the foliar application.
The spider mites disappeared and did not reappear all season. The grower harvested 215 bushels organic corn.

Nitrogen present in wet soil converts to ammonium. (This is why rice and blueberries are adapted to only absorb NH4.)
During high leaf temperatures, plants switch from photosynthesis - dominant to photorespiration - dominant
During photorespiration-dominance plants sustain themselves with energy from protein catabolism rather than from sugars.
Mite Prevention 1.Reduce leaf temperature 2.Manage nitrogen applications with precision
Manage leaf temperature by increasing plant lipids.
Apply minimal amounts of nitrogen as indicated by sap analysis.

Why do growers see mite populations soar as temperatures get higher? In this webinar, John Kempf describes what causes mite populations to explode and how to control mites with nutritional inputs. He will illustrate why high temperatures cause plant ammonium levels to increase and describe how these high levels influence mite populations. If you’ve experienced mite issues, whether from high temperatures or other causes, this webinar will provide actionable information on:

• The conditions that are vulnerable to exploding mite populations
• The causes of these conditions
• The nutritional inputs that can reverse mite infestations
