A weed killer, also known as an herbicide, is a type of chemical or natural substance used to control or kill unwanted plants, commonly referred to as "weeds." Weed killers work by disrupting the metabolic processes of the plants, inhibiting their growth, or killing them outright. They can be applied directly to the leaves, stems, or roots of the plants, or used as a pre-emergent treatment to prevent weed seeds from sprouting. Weed killers are commonly used in agriculture, landscaping, and home gardening to prevent the growth of unwanted plants that can compete with desired crops or plants for resources such as water, nutrients, and sunlight. It is important to use weed killers according to their labeled instructions to avoid damaging desired plants or harming the environment.

Garden fungicides are chemical products used to control or prevent fungal diseases in plants. Fungal diseases can be a major problem in gardens and can affect various parts of the plant, such as leaves, stems, flowers, and roots. Fungicides work by killing or inhibiting the growth of fungi that cause these diseases.

There are many different types of garden fungicides available, including organic and synthetic options. Organic fungicides are made from natural ingredients, such as copper, sulfur, neem oil, and baking soda, and are generally considered to be safer for the environment and beneficial insects. Synthetic fungicides are made from chemical compounds and can be more potent and effective, but may also be more harmful to the environment and can lead to the development of resistant strains of fungi.

When using any garden fungicide, it's important to carefully follow the instructions on the label and use the product as directed. It's also a good idea to wear protective clothing and avoid spraying on windy days to minimize the risk of inhaling the product or accidentally getting it on your skin. Additionally, it's important to properly store and dispose of any unused product according to local regulations to avoid environmental contamination.
