What Went Wrong: Knowing and Fighting Plant Diseases

plant diseases

Diseases of plants often seem mysterious because you can’t really notice them right away, unless you use a microscope. Most home gardens have only modest disease problems, but it’s important to make sure you keep the upper hand by learning to recognize the symptoms of diseases that might lead to your paradise’s destruction.

If your plant slowly wilts or rapidly collapses it is likely caused by soil-borne fungal diseases that causes roots to rot.

  • If the new growth of your plant looks crinkled or distorted with crazy flowering patterns or thickened leaves, it is likely caused by viruses which are spread by small insects that interfere with the DNA signaling within plants. If the leaves of your plant have white patches or numerous dark spots, it is likely caused by airborne fungal diseases such as powdery mildew.

Most diseases that infect vegetable garden plants are caused by fungi. By the time you see a problem, it is usually too late to cure it. Most diseases are predictable though, which gives you plenty of opportunity to try these simple preventive methods:

Baking soda

This can help prevent powdery mildew and other leaf spot diseases. Mix one teaspoon of baking soda per quart of water with a few drops of liquid soap added to help it stick. Baking soda is particularly effective when used in rotation with light horticultural oils.

Horticultural Oils

It may be based on soybean, canola or even herbal essential oils. These oils make leaf surfaces inhospitable to fungi, but they can damage leaves when applied during hot weather. Always check on the product label to make sure the plant you want to treat is on the list. Follow application instructions precisely.

Plain Milk

when diluted in water and exposed to sunlight, it briefly changes into a disinfectant compound that murders fungal spores yet act gently on plant leaves. Mix one half cup milk to two cups of water. Apply weekly on healthy plants that are at high risk for developing powdery mildew.

Pruning or Pinching off

Pruning or pinching off upon observing the first sign of trouble is a smart intervention too. When the lowest leaves of your plant start showing dark spots from early blight, clipping them off can seriously slow down the spread of the disease.

Taking care of your garden is like taking care of yourself. Remember the old saying? Prevention is better than cure. In your garden’s case, it’s best for you to be knowledgeable regarding these plant diseases and to be a keen observer at all times.
