What is the best guide for the safe use of a pesticide on a specific plant?

The pesticide label is the best guide for the safe use of a pesticide on a specific plant because it provides essential information directly related to the product's use, including application rates, timing, and methods, as well as details about the plants that the pesticide is safe to use on. It includes critical safety information regarding potential hazards to humans and animals, personal protective equipment requirements, and any specific precautions needed to minimize environmental impact.

The manufacturer's brochure, while useful for promotional purposes or general product information, may not contain all the detailed safety instructions and regulatory requirements found on the pesticide label. Gardening handbooks tend to offer broader gardening advice and may not focus specifically on the safety and application of individual pesticides. Extension service guidelines can provide valuable insights and recommendations for pest management in a regional context but are often based on general practices rather than the specific chemical details contained in the pesticide label. Thus, relying on the labels ensures that users have the most accurate and specific information to promote safe and effective pesticide use.
