Identification, such as PD20080005. For sanitary pesticides, the temporary registration number is “WLâ€, such as WL20060315; the official registration number is marked with “WPâ€, such as
WP20070316. When purchasing pesticides, you can ask the dealer to issue a copy of the pesticide registration certificate, and check it after purchase.

Do not purchase pesticides that have no production date or have expired.

When the pesticide product contains two or more different types of active ingredients, the product color marking tape shall be composed of the marking tape segments corresponding to the respective active ingredients. Fungicide - black, insecticidal / cockroach / snail - red, herbicide - green, rodenticide

According to the “Pesticide Toxicity Grading Standardâ€, the pesticide toxicity in China is divided into five grades: highly toxic, highly toxic, moderately toxic, low toxic and slightly toxic. Different toxic pesticide products should have different levels of marks, and the red mark should be used to indicate the toxicity corresponding to the mark, such as: highly toxic, highly toxic, moderately toxic, low toxic, and slightly toxic.
