Pendimethalin
| Product Name | Pendimethalin |
| Cas no. | 40487-42-1 |
| Physical and Chemical Properties | Molecular Formula: C13H19N3O4 Molecular Weight: 281.31 Melting Point: 56-57°C Density: 1.17 g/cm³ |
| Formulation | 30% EC,33%EC |
| Application | Mode of action :Dimethylene is a dinitrotoluidine herbicide, which mainly inhibits the division of meristem cells and does not affect the germination of weed seeds, but acts on the absorption of the drug by the young buds, stems and roots during the germination of weed seeds. The absorption site of dicotyledon plants is hypocotyledon, while that of monocotyledon plants is young buds. The harm symptom is that the young buds and secondary roots are inhibited to achieve the purpose of weed control. Uses: Provides control of Echinochloa spp., as well as many broadleaf, sedge and aquatic weeds in rice. Penoxsulam provides residual weed control, depending on soil type and use rate. In tropical rice, application will be at 10-15 g/ha; in temperate rice, 20-50 g/ha. Primary use will be a post-emergence application in dry-seeded, water-seeded and transplanted rice. |
| Storage | Sealed and keep in coold and dry place,APPROX 4°C |
| Toxicity | Dimethylene is a low-toxicity herbicide. In rats, the oral LD50 was 1250mg/kg, and the acute inhalation LC50 was greater than 320 mmol /m3. Highly toxic to fish. |
| Usage precautions | 1, dimethylpentalin is highly toxic to fish, pay attention to use, must not pollute water and fish ponds. [1] 2, in the corn, soybean field application, sowing depth should be 3~6 cm, covered with soil, to avoid seed contact with the agent. [1] 3, in the soil treatment, the first application of medicine after irrigation, can increase the adsorption of soil agents, reduce drug damage. In fields with lots of dicotyledonous weeds, it should be considered to mix with other herbicides. [1] 4. On sandy soil with low organic matter content, it should not be applied before seedling. 5. In the case of low temperature or after the application of watering and heavy rain may cause minor harm or affect the drug effect, about 7 days after the application of topsoil drought will also affect the drug effect. 6. Wear protective clothing or use protective facilities when applying medicine. 7. Wash face and other exposed parts thoroughly with water and soap after application. 8. Avoid contact with skin, eyes or clothing, and avoid inhaling fog. 9. Don't eat, drink or smoke while working. 10.Do not use in the heat source or open flame, reverse the product to avoid the liquid directly sprayed on the water source. Do not contaminate water or water sources when cleaning equipment or disposing of waste. Used containers should be cleaned three times, buried, or burned. |
