Nutrition Management for Mite Infestations

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

This is an awesome presentation, thanks for sharing! I appreciate your willingness to discuss the research behind your products.

Thank you so much for sharing all of this, I am so grateful.

Wow this works well. Been fighting spider mites in a small indoor garden for over a year. I have used predator mites, environmental modification, increased ventilation etc. I sprayed a tea of Gypsum (S), Epsom salt (mg) and molasses (carbs) yesterday. Mites are all gone today.

Have you ever talked about using saponins in drought stressed soils?

Looking at sap analysis for the peaches 8:00min-9:00min, John points out the difference in ammonium between year with mites and year without mites . (with / without) Sugar: 6/5 NH4: 176/92. So the sugar was about the same and the ammonium was almost twice as much with mites. Ok, but looking at all the other numbers, I see other nutrient levels that are more substantially different. pH: 6/12 EC: 12/5. Ca: 27/69 TN: 1335/728.... So are the pH numbers correct? If so, at pH 12 (which seems wrong) there's only ammonia(NH3), not ammonium(NH4). as a rule of thumb you have NH4 below pH8 and NH3 above pH8 How does the prevalence of NH3 vs NH4 effect mites? EC correlates with brix, why would there be more mites with higher brix? The calcium is less than 1/2 when there are mites...low calcium seems like it would definitely increase the susceptibility of mites, I would guess more than a difference in ammonium?

@ Advancing Eco Agriculture . Fall Army Worm is now is Queensland Australian. Have you done any shows or interviews about them? I'd like to know what are the triggers for the pest and how to manage nutrition and plant health without using chemical insecticides.

Love your work. Thanks

I wonder if an application of chalk on tree crops would also help. It would reduce leaf temperature by sun reflection - a practice applied in Spain to avoid heat stress in citrus.

[iwenive]

It undoubtedly changes the leaf emissivity

The wax probably creates a vapor barrier/ insulation barrier. Modern buildings use exoinsulation vapor barriers to significantly reduce heat loads

John I came across detail stating an increase in iron level tends to increase phosphorous & sulphur level in plants.
Pls share your valuable comment on same.

@AdvancingEcoAgriculture. Also, John mentioned that when the soil becomes more anaerobic, the nitrate in the soil converts to ammonium. Is that actually true? Everything I've seen in the field and read, shows that denitrification converts nitrate to N2 gas (not ammonium). Is it possible that maybe the nitrate is not converting to ammonium, but you see higher levels of ammonium under anaerobic conditions because 1)the aerobic microbiology is dying and their bodies are decomposing, their amino acids denature into ammonium. 2) the new ammonium from dead aerobes is no longer converting to nitrate, because there's not enough oxygen. Therefore the new ammonium just stays in it's current state. I'm not an expert, but this seems like a more reasonable explanation for the phenomenon John describes.

I live in Germany, is there a good lab for doing sap analysis? What does it usually cost? Do you ship your Products to Germany?

[littlebeebs]

Do I need all three products? I have Brevipalpus mites on my indoor succulents. I have over 300 succulents. I’m so tired of the mites . Pure sulfur burns them . They’re under LED grow lights . Thank you ! I had a feeling nutrients could make them less susceptible.

48:55 "For most crops, the peak nitrogen requirement is not when the plant is young, in early spring, it's later on, during the fruit build period."

Hi John are mealy bugs attracted to high ammonium levels similar to mites ans thrip?

[Rehealise]

Could you elaborate on the interaction between mite damage/plant health and gravel roads/ “dirty” foliage.

We use kaolin clay throughout the season to deter pests, chelate nutrients, and minimize sunburn. Could clay be having a similar negative effect on plant health?

[jjime]

So could high nitrogen levels in an orchard environment be contributed by excessive mowing of grass surrounding the trees?

[МиколаБиков-ны]

Very well said. I doubt it works. because it is unclear how to apply it in practice. how to achieve the first, second and other stages of health.

[alireid]

I would be really interested in a webinar that discusses the differences in plant responses to GMO inputs versus natural input. There's not nearly enough credible, real world information available detailing this.

when we have really high TEMPERATURES!!! god dang my ears :) brilliant subject though after watching some of the other videos it makes me think youre better of spraying watered down honey or something rather than insecticides.
