Is Eagle 20 a broad spectrum fungicide or just for powdery mildew. Also, can it be mixed with Companion or other chemicals when sprayed.

How important is it to get the underside of the leaves when foiliar spraying?

It is of absolute importance to get the underside of the leaves when spraying. Eagle 20 is a treatment for foliar diseases mainly. We mix Eagle 20 with Merit, Bifen and / or Daconil with good success. I don't know about Companion.

I thought eagle was a systemic so spraying the underside of leaves not important because the active ingredient will spread throughout the entire plant?

My understanding is that it's systemic as well.

Wanting to learn a bit here...does systemic mean...only taken in by root system? If not, then spraying a systemic on leaves works too, and if true...then spraying on bottom of leaves...where stomota are more previlant would help? I guess my question is, would spraying where uptake would be more efficient, help the systemic quality of the product? Peace, Wayne

Wayne,

From Wikipedia:
Pesticides can be classified based upon their biological mechanism function or application method. Most pesticides work by poisoning pests.[9] A systemic pesticide moves inside a plant following absorption by the plant. With insecticides and most fungicides, this movement is usually upward (through the xylem) and outward. Increased efficiency may be a result. Systemic insecticides, which poison pollen and nectar in the flowers, may kill bees and other needed pollinators.

And to answer your question, I would think that it's a strong possibility. Keep in mind to only use this on ornamentals and nothing in your vegetable garden.

I know it's highly effective on powdery mildew, but I know of some good organic methods as well (though eagle 20 stays in the plant, protecting it for the life of the plant from what I understand). Most other solutions I know of that are organic will require more frequent application (horticultural oils, I use a strong neem oil that's been emulsified with liquid silica and aloe).

Tad, local box stores don't sell "liquid silica and aloe" , or maybe they do, and I just don't know what to look for? Thanks again for your input. & will consider AG's as an Ornamental!!! LOL Thanks, again!!! Peace, Wayne

Wayne,

Aloe is high in saponin content and silica moves through the soil so it's very good to add during waterings. It's one of the most under-appreciated minerals.

http://www.fngla.org/education-and-research/research/reports/75/finalreport.pdf

For powdery mildew, here's what I do:
Foliar Spray for Powdery Mildew (2-3x week) per quart
1 t. Neem Oil
½ t. ProTekt
1 T. Aloe
Pre-mix the neem and ProTekt in shot glass before adding to water/aloe mix in sprayer. Shake well. Use warm water.

Regular Watering (approx. every 3 days)
1 t. ProTekt/gal of water
Seaweed Extract and LC-10+7
This recipe is per gallon of water. (2x per week, both foliar and soil drench)
1 T of liquid seaweed concentrate (see below on how to make)
2-3 teaspoons of LC-10+7

To make the concentrate, mix 1 oz (2 Tablespoons) of seaweed extract powder with 1 pint (2 cups) of water. Store in container with the cap cracked or in the fridge with lid cracked (it will slowly ferment, but it doesn’t affect efficacy, as you’ll go through this amount in 8 weeks max.)

I get the liquid silica from hydro shops (Dynagrow ProTekt), or you can find it online. For neem, I go through www.neemresource.com, it's neem product is better than everything else on the market, though you might be able to find something else locally. Lastly, the aloe can be purchased at a local PCC or Whole Foods or Trader Joes. The less preservatives the better. I got George's Aloe online that's preservative free, but it would cost more.

Hope that helps!

Oh, and the regular watering is unrelated to the powdery mildew solution, it's just my way of feeding the plants when I'm not doing ACT applications.
