Herbicide

Herbicides refer to the agents that can completely or selectively cause the death of weeds, and they are also known as weed killers. Herbicides are divided into inorganic compound types and organic synthetic types. Herbicides should possess characteristics such as high efficiency, selectivity, and convenience in use. Some herbicides, such as paraquat, can function by inhibiting the photosynthesis of weeds, blocking the photosynthetic electron transfer or inhibiting the synthesis of photosynthetic pigments. Some herbicides, such as naphthalene acetic acid, can interfere with the hormonal balance of plants, leading to abnormal growth and death of weeds. There are also some herbicides that can inhibit plant cell division or amino acid synthesis. Herbicides are widely applied in agricultural farmlands, garden green spaces, along roads and railways, industrial sites, etc., to control weeds, so as to ensure the growth of crops, maintain the landscape environment, and reduce potential safety hazards such as fires^[1]^[2].

HY-B2035

Pretilachlor		99.25%
Pretilachlor is a chloroacetamide herbicide with biological activities including endocrine disruption, oxidative stress induction, apoptosis induction, and immunotoxicity. Pretilachlor exerts its effects by interfering with hormone metabolism, inducing oxidative stress, activating apoptotic pathways, and inhibiting immune functions. Pretilachlor upregulates the transcription of P53, Mdm2, and Bbc3, and increases the activities of Caspase3 and Caspase9; it upregulates the transcription of genes in the HPG/HPT axis and the activity of aromatase; it induces oxidative stress, elevates ROS levels, and upregulates CAT, SOD, and GPX. Pretilachlor downregulates the transcription of CXCL-C1C, IL-1β, and IL-8. Pretilachlor disrupts the normal physiological processes and embryonic development of fish, exhibiting significant toxicity. Pretilachlor can be used in studies related to weeding, environmental pollution, and behavioral toxicity in fish.
