Write a recipe for a DIY insecticide/fungicide plant spray using garlic. Include a three-sentence introduction, a bulleted list of ingredients, and step-by-step instructions in paragraph form.
In addition to repelling pests, garlic has strong antifungal properties. Garlic spray controls fungal plant diseases like leaf spots, early and late blight, and powdery mildew. This spray also works as a contact insecticide. However, be aware it will kill pests and beneficial insects like ladybugs, so be mindful of your little garden helpers when applying it. 
DIY Garlic Spray to Control Insects and Fungus
- 1 head of garlic
- 2 cups of water
- 1 tablespoon of bleach-free dish soap
- 2 tablespoons of mineral or vegetable oil
Peel the garlic, place the cloves and water in a food processor or blender, and liquefy. Let the mixture sit overnight. Then, strain out any remaining garlic pieces and pour the liquid into a clean spray bottle. Next, add the liquid dish soap and mineral or vegetable oil and shake the bottle vigorously to blend. 
Spray all plant parts thoroughly, including both sides of the leaves. Fungal spores tend to emerge on the leaves undersides, and it's also a favorite hiding spot for insects.
This DIY garlic spray is also an effective pest repellent. Use it wherever you notice significant pest activity in your garden. To avoid accidentally burning the plant's leaves, it's best to test home remedies like this on a small part of the plant first and monitor for any adverse reactions.
