| brief introduction | dimethyl pentalin, also known as sprouting, weeding and field tonic, is a touch-killing soil blocking treatment agent, which mainly inhibits meristem cell division and does not affect the germination of weed seeds, but works after the sprouts, stems and roots absorb drugs during the germination of weed seeds. the absorption site of dicotyledonous plants is hypocotyl, monocotyledonous plants are young buds, and the damage symptom is that the growth of young buds and secondary roots is inhibited. The drug has a wide spectrum of herbicides and has a good control effect on a variety of annual weeds. At present, there are 33%, 50% emulsifiable concentrate, 3%, 5%, 10% suspending agent, etc. |
| application scope | the production of dimethyl pentalin has a wide range of weeding, which is suitable for rice, cotton, corn, tobacco, peanuts, vegetables (cabbage, spinach, carrot, garlic, onion, etc.) and orchard crops, and for the control of annual gramineous and broadleaf weeds such as crabgrass, Setaria, barnyard grass, purslane and quinoa. |
| efficacy and action | dimethyl pentalin is a herbicide used for pre-seedling sealing, which is mainly absorbed by the buds, stems and roots of weeds to inhibit the cell division of buds and secondary root meristem, thus hindering the growth of weed seedlings and leading to weed death. The application method is mainly soil spray treatment. After application, dimetaline is easy to be adsorbed by soil particles, and will not be dissolved into the deep layer of the soil with water. The duration is moderate, generally 45-60 days. The higher the soil water content after application, the better the weeding effect, and the worse the weeding effect under drought conditions. |
| toxicity | acute oral LD501250mg/kg in rats; LD501620mg/kg in mice; Acute percutaneous LD50>5000 mg/kg in rabbits; Acute inhalation of LC50>320mg/m3. No irritation to the skin and eyes. The 2-year feeding test for rats had no effect at a dose of 100mg/kg per day. There was no teratogenic, carcinogenic and mutagenic effect on animals within the test dose, and there was no abnormality in the three-generation reproduction test and delayed neurotoxicity test. The unaffected dose of blue gill fish was 0.1mg/L, rainbow trout 0.075mg/L and catfish 0.32mg/L. Mouth LC50 of wild ducks is 10338 mg/kg and quail LC504187mg/kg. The oral LD50 of bees is 50 μg/bee. |
| use | dinitroanilines herbicides. Inhibition of meristem cell division. During the germination of weed seeds, the young buds, stems and roots work after absorbing the agent. The absorption site of dicotyledonous plants is hypocotyl, and the monocotyledonous plants are young buds. The damage symptom is that the young buds and secondary roots are inhibited. It can be used in corn, soybeans, wheat, cotton, vegetables and orchards to control weeds such as barnyard grass, crabgrass, Setaria, bluegrass, quinoa, and amaranth. 30-45mL/100 m2 of 33% emulsifiable concentrate (active ingredient 10-15g/100 m2) for soybean and peanut fields, 30mL/100 m2 of 33% emulsifiable concentrate (active ingredient 10g/100 m2) for corn fields and 15-22mL/100 m2 of 33% emulsifiable concentrate (active ingredient 5-7.5g/100 m2) for vegetable fields. Selective herbicides, control of annual gramineous and certain annual broadleaf weeds. Cereal plants, corn and rice are applied before seedlings after sowing, or in broad beans, cotton, peanuts and soybean sprouts. Vegetable fields can be applied before seedling or transplanting, and tobacco roots can also be prevented. Used to control annual gramineous and certain broadleaf weeds |
| Production method | The first nitration method reacts with 3, 4-dimethylchlorobenzene and nitric acid to produce 3, 4-dimethyl-2, 6-dinitrochlorobenzene, and then reacts with 1-ethylpropylamine to produce divalerol. The post-nitrification method was used to alkylate and nitrification 3, 4-dimethylaniline to obtain dimethylpentalin. |
