Herbicide
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].

Fenoxaprop-P-ethyl
0 ImagesFenoxaprop-P-ethyl is an acetyl-CoA carboxylase (ACC) inhibitor and post-emergence herbicide. Fenoxaprop-P-ethyl inhibits the conversion of acetyl-CoA to malonyl-CoA, reduces malonyl-CoA synthesis and disrupts fatty acid synthesis. Fenoxaprop-P-ethyl disrupts lipid homeostasis through cascaded inhibition of lipid metabolism, decreases total lipid content, downregulates fatty acid elongase genes and inhibits their activity. Fenoxaprop-P-ethyl disrupts fatty acid synthesis in rice seedlings and controls annual monocotyledonous weeds in wheat, durum wheat, rye, triticale and barley fields.

Napropamide
0 ImagesSynonyms: NapropamidNapropamide (Napropamid) is an amide herbicide that can be used to control weeds in fruits, vegetables, tobacco, and ornamental plants. Napropamide mainly exerts its effect by inhibiting DNA synthesis and cell division. Napropamide has moderate to high persistence in the field, with a half-life of 24-131 days, and is prone to photodegradation.
-
Imazapic
0 ImagesImazapic is an imidazolinone herbicide. Imazapic is an inhibitor of acetolactate synthase, which inhibits branched-chain amino acid biosynthesis, thereby hindering protein synthesis and cell growth and exerting herbicidal activity. Imazapic exerts a lethal effect only on Phelipanche aegyptiaca that has already parasitically attached to tomato roots, and has no inhibitory effect on unattached broomrape seeds and seedlings. Imazapic can control weedy annual grasses, non-grass herbaceous plants, and downy brome, but can damage perennial forage grass species. Imazapic can be used in herbicide-related research.

Pretilachlor
0 ImagesPretilachlor 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.

Diuron-d6
0 ImagesDiuron-d6 is the deuterium labeled Diuron (HY-B0860). Diuron is an orally active phenylurea herbicide. Diuron inhibits photosynthesis in plants by blocking the formation of ATP and NADH. Diuron increases the production of ROS. Diuron increases expression of p53 in certain cell lines. Diuron has herbicidal activity against annual and perennial broadleaf weeds and grass weeds. Diuron promotes DMBA/BBN-induced bladder cancer. Diuron can be used in breast cancer research.

Quinclorac
0 ImagesQuinclorac is a highly selective quinoline carboxylic acid synthetic auxin herbicide. Quinclorac weakly inhibits HPPD, accompanied by a transient decrease in carotenoids. Quinclorac upregulates ACC synthase (ACS), leading to the co-accumulation of ethylene and cyanide, while increasing the ABA/IAA ratio, which induces ROS burst, membrane lipid peroxidation (MDA) and lethal growth inhibition. Residual Quinclorac in soil can cause abnormal growth of subsequent tobacco crops. In calli of Phaseolus vulgaris, Quinclorac induces oxidative stress (increased MDA and decreased RGR), but cells after stepwise pressurized acclimation acquire a constitutive antioxidant state, which remains stable after de-acclimation and tolerates oxidative damage caused by Quinclorac. Quinclorac can be used in studies related to herbicide action mechanisms, bioremediation of soil residues, and adaptive responses of plant cells to oxidative stress.

Diallate

Iptriazopyrid
0 ImagesSynonyms: NC-656Iptriazopyrid is a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor, with a Ki value of 24.3 nM against Arabidopsis thaliana and 33.3 nM against Oryza sativa. Iptriazopyrid binds to the active pocket of HPPD, occupies the catalytic site, inhibits carotenoid biosynthesis, prevents chloroplast formation, and induces albino and chlorotic symptoms in sensitive plants. Used as a herbicide, Iptriazopyrid can control barnyardgrass when applied alone, and its efficacy does not decrease when mixed with labeled residual herbicides. When Iptriazopyrid is mixed with 2,4-D or triclopyr, its barnyardgrass control effect shows an antagonistic effect. Iptriazopyrid is a triazole carboxamide herbicide that exhibits selectivity for Oryza sativa over Echinochloa crus-galli, and has partial tank-mix compatibility with synthetic auxin herbicides registered for rice.

MCPA-d3
0 ImagesMCPA-d3 is the deuterium labeled MCPA (HY-B0859). MCPA is an orally active phenoxyacetic acid herbicide. MCPA interferes with membrane integrity, energy metabolism (decreases ATP levels), and redox balance in plant cells. MCPA increases hepatic cytochrome P-450 levels and increases aniline hydroxylase and 7-ethoxycoumarin O-deethylase activities. MCPA can be used to control broadleaf weeds.
