Multi-read content how to prevent powdery mildew on plants

Providing adequate air circulation will help prevent powdery mildew in your garden

From the number of questions I receive each summer about a plant fungus called powdery mildew, I have learned three things over the years; it’s everywhere, you don’t like it and you want to know how to get rid of it. Here is what you need to know to prevent it, control it and even get rid of it once it has appeared.

You’re not alone

Powdery mildew is one of the most common and recognizable fungal diseases of crops. From the vegetable garden to the rose garden, passing through ornamental plants, shrubs, almost no plant can be immune.

If you notice that some of your plants or trees have powdery mildew, don’t worry. This fungus is host-specific, which means that just because you find it on one plant doesn’t mean it poses a threat to other plants in your landscape. Although there are many different species of powdery mildew, all symptoms are the same from species to species.

What are you looking for

You may have seen it many times. Powdery white or gray spots appear, often covering most if not all of the leaf surface. It is also found on stems, flowers and even fruits. Fortunately, the symptoms of powdery mildew are often more serious than the actual damage. It is rarely lethal to plants.

The heavy growth stage can cause the leaves to yellow, curl or brown and eventually drop the plant’s leaves prematurely. On flowering plants and trees, the fungus can cause premature bud drop or reduced flower quality.

So how about now?

Conditions favorable for mold growth include dry foliage, high humidity, low light and moderate temperatures. Proactive measures to avoid or reduce this risk include:

· Look for disease-resistant varieties. Contact your localdepartmental extension servicefor the named varieties and plants.

· Ensure adequate air circulation by avoiding overloading the shafts.

· Decorate plants where they receive sufficient light for six hours or more each day. Minimize shade and prune trees and bushes that block light.

Avoid over-fertilizing. New developments are more sensitive. Instead, apply a slow-release fertilizer for more controlled growth.

Take control of an existing problem

If you find it necessary to react to an existing powdery mildew condition, early detection is the best way to prevent and potentially eliminate the problem. There are many commercial products that are effective in stopping the spread. However, the elimination of an existing problem is not certain.

Most conventional products are designed to prevent and control, not eliminate, an existing infection. This is why it is important to start a control program before powdery mildew appears or at least the first signs of detection.

There are many over-the-counter fungicide products that work against mold. One of the most commonly used active ingredients for control is “chlorothalonil”. Although effective, it coats the surface of the leaves with a fairly noticeable milky white film.

Lesser known options include:

Baking soda (sodium bicarbonate)) -This is perhaps the most well-known of the homemade organic powdery mildew solutions. Although studies show that baking soda alone is not at all effective, when combined with horticultural or sleeping oil and liquid soap, the effect is very good if applied in the early stages or before the epidemic.

Use this recipe to make your own: mix a tablespoon of baking soda with a teaspoon of sleeping oil and a teaspoon of insect repellent or liquid soap (not detergent) with a gallon of water . Spray the plant every one to two weeks.

Potassium bicarbonateSimilar to baking soda, this has the one benefit of actually eliminating powdery mildew once it’s there. Potassium bicarbonate is a contact fungicide that quickly kills powdery mildew spores. In addition, it is approved for use in organic farming.

Mouthwash- If it is possible to destroy pathogens in the mouth, the fungal spores of powdery mildew are surely unmatched. And that’s the premise. Ethanol-based mouthwashes can be very effective in controlling. Trials using one part mouthwash to three parts water worked for Jeff Gillman, PhD and associate professor at the University of Minnesota, Department of Horticulture. Just be careful when mixing and applying the mouthwash as the new foliage may be damaged.

VinegarSimilar to mouthwash, the acetic acid in vinegar can control powdery mildew. A mixture of 2 to 3 tablespoons of regular apple cider vinegar, containing 5% acetic acid mixed with a gallon of water will work. However, too much vinegar can burn the plant but at the same time a higher concentration (more than 5%) will be more effective.

Sulfur and Lime / Sulfur- Direct contact with sulfur prevents the development of disease spores. When mixed with slaked lime, this solution penetrates the leaves, giving a superior effect. A widely available version of this combination consisting of copper sulphate and hydrated lime is known as Bordeaux mixture. However, all of these solutions can burn plant tissue and harm soil microorganisms and beneficial insects. It is also considered moderately toxic to mammals and humans. Use sparingly and with caution if available.

Milk- The new player in the fight against powdery mildew is milkweed. It’s still unclear why it works so well, but the natural compounds found in milk are thought to work to fight disease while boosting the plant’s immune system. An experiment showed good results by applying a weekly dose of one part milk to two parts water.

Drink water- Ironically, dry conditions and high humidity are the most favorable conditions for the formation of powdery mildew. But pure water is its enemy because it washes away the spores before they have time to soak in it. However, water is not something I recommend for control as wet foliage is a friend of many other plant diseases. If you’re going to try this option, do it early in the day to give the foliage time to dry quickly.

neem oil- It is a readily available organic option for disease and pest control. Neem oil is extracted from the neem tree, which is native to India. It is an effective disease control measure and a broad-spectrum natural insecticide that is good for beneficial insects and mammals. For powdery mildew control, results vary but it is not the best choice. The results are generally moderate.

Even when there are many control options, prevention is still the best cure, not only for powdery mildew but for other diseases as well.
