What are the common types of herbicides? What varieties are there under these types of herbicides? We ask knowledgeable readers to help explainHerbicides can be classified by mode of action into systemic translocated herbicides and contact herbicides; if classified by action, they can be divided into selective herbicides and non-selective herbicides; Zhongdiwang has compiled the information on herbicides according to the above classification, and the following is listed for readers' reference.
I. Systemic translocated herbicides:
This type of herbicide is mainly applied to plants or soil, and is absorbed through the roots, stems, leaves, embryos and other parts of weeds and transported to the sensitive parts of the weeds or the entire plant, causing the weeds to be poisoned and die; common varieties are bensulfuron-methyl, glyphosate, etc.
II. Contact herbicides:
This type of herbicide cannot be absorbed or conducted by plants, and can only kill the plant tissues it contacts; common ones include paraquat, bentazone, etc. (When applying, pay attention to protecting cash crops to avoid accidental damage to crops.)
III. Selective herbicides:
This type of herbicide is selective toward plants, killing or inhibiting some plants while being safe for other plants within a certain dosage and concentration range; common ones include cyhalofop-butyl, etc. (When applying, the dosage on the packaging must be followed when mixing the pesticide to avoid phytotoxicity to cash crops.)
IV. Non-selective herbicides:
This type of herbicide can kill all plants that come into contact with the agent at commonly used doses; common varieties include glyphosate, glufosinate-ammonium, bromoxynil, gramoxone, etc. (When applying this herbicide, farmland crops should also be protected to avoid unnecessary phytotoxicity.)
