Effective period Imidacloprid: 210 days Chlorpyrifos: 120 days 4, security Imidacloprid: high (nicotine) Chlorpyrifos: poor (organophosphorus) 5, applicability Imidacloprid: broad spectrum (multiple crops available) Chlorpyrifos: peanuts, corn 6, smell Imidacloprid: not taste Chlorpyrifos: Stimulating taste 7, insecticidal spectrum Imidacloprid: underground pests, aphids Chlorpyrifos: broad spectrum of insecticides, seed dressing is mainly underground pests 8, regional Imidacloprid: suitable for all areas Chlorpyrifos: local area is invalid Want to know more about pesticide seed dressing, please pay attention to pesticide network Deep Groove Ball Bearing is the most representative structure in rolling bearing, which is widely used. In addition to radialload, this kind of bearing can also be loaded with bidirectional axial load. The friction torque is small, and it is most suitable for adjusting rotation, low noise and low vibration. Bearings are widely used in automobile, electrical, instrumentation,construction machinery, agricultural machinery and various professional machinery. This kind of bearing has open and closed deformation structure.
