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-B1853

Simetryn		99.75%
Simetryn is a triazine herbicide that exerts teratogenicity. Simetryn inhibits photosynthesis by blocking electron transfer in the chloroplast photosystem II and activates the MEK/Erk signaling pathway. Simetryn triggers vascular and developmental abnormalities in zebrafish and tadpoles, suppresses proliferation, enhances apoptosis, and induces malformations. Simetryn serves as a tool to establish a zebrafish model for studying arteriovenous malformations and related pathogenesis. Simetryn controls paddy weeds and can be used for research on developmental and vascular disorders.

HY-137910

Tembotrione		99.41%
Tembotrione is a herbicide belonging to the HPPD (dioxygenase) inhibitor class with crop selectivity. Tembotrione effectively controls a variety of weeds including broadleaf and gramineous species by disrupting carotenoid synthesis, which leads to chlorophyll degradation and leaf whitening. Mixing Tembotrione with isoxaflutole or adding surfactants optimizes its efficacy and reduces phytotoxicity, with no residual impact on subsequent cruciferous crops, thus helping to increase maize grain yield. The activity of Tembotrione decreases under drought conditions, and under specific conditions (such as double-dose treatment), it may cause reversible yellowing and even yield reduction in crops such as poppy.
