Botanical pesticides are natural substances derived from plants that are used to control pests. These pesticides can be effective against insects, fungi, and weeds, and they often break down more quickly in the environment compared to synthetic chemicals. Common examples include neem oil, pyrethrin, and rosemary oil, which are known for their pest-repelling properties. One of the main advantages of botanical pesticides is their lower toxicity to humans and non-target organisms, making them a safer option for gardens and farms. However, their effectiveness can vary based on factors like application method and environmental conditions, so proper usage is essential for optimal results.
