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].

Herbicide safener-3
Herbicide safener-3 is a compound that increases the selectivity of herbicides. Herbicide safener-3 is often used together with herbicides, particularly those that can be harmful to crops. Herbicide safener-3 reduces the negative effects of herbicide on the crop by regulating metabolic differences between the crop and the weed while still allowing the herbicide to be effective on the weed. Herbicide safener-3 can be used in research that improves herbicide application effectiveness and crop safety.

HY-W728891

Pentoxazone
Pentoxazone is a protoporphyrinogen IX oxidase (PPO)-inhibiting herbicide. Pentoxazone inhibits chlorophyll and heme synthesis, drives protoporphyrinogen IX accumulation and oxidation, and generates singlet oxygen to oxidize cell membranes and induce cell damage.Pentoxazone suppresses fresh weight growth of multiple weed species and shows low activity against weedy rice. Pentoxazone can be used for the research of direct-seeding rice field weed management.

Digalactosyldiacylglycerol
Digalactosyldiacylglycerol is a membrane structure stabilizer that selectively acts on photosystem II light-harvesting complex II (LHCII), serving as a natural bilayer-forming lipid in plant thylakoid membranes. Digalactosyldiacylglycerol constructs a lipid bilayer environment with monogalactosyldiacylglycerol (MGDG) in a 2:1 molar ratio, stabilizing the supramolecular structure of LHCII through interactions such as hydrogen bonding. Its core activity is maintaining thylakoid membrane stacking (grana formation) and supporting photosynthesis-related functions, while also possessing functions in light harvesting assistance and excitation energy quenching regulation under light stress. Digalactosyldiacylglycerol can be used in research on plant photosynthesis mechanisms, thylakoid membrane structure and function regulation, as well as in the construction of artificial photosynthetic systems and the development of plant photoprotection strategies.
