The first is the correct selection of pesticides. When selecting a pesticide, it is necessary to understand its characteristics and strictly follow the scope of prevention and treatment indicated by the label. When buying, you should prevent counterfeit and shoddy products and ask for a purchase invoice or credit card.
Second, when taking medicine, it is necessary to look at the sky, see the ground, and see the seedlings, to avoid adverse weather, bad lyrics, sensitive crop varieties and medication during the growth period.
The third is the scientific application of pesticides, strictly in accordance with the scope of control and dosage on the label. Do not arbitrarily expand the control of crops and increase the concentration. It is necessary to apply the drug evenly at one time, avoid repeated use of drugs, and do not mix pesticides in order to avoid the occurrence of phytotoxicity. Herbicides are different from pesticides. Herbicide use is slightly inappropriate, but it may lead to crop failure. For herbicides, “pharmaceutical effect†and “drug damage†are often only one step away. Therefore, it is especially cautious when selecting and using herbicides. It is necessary to master scientific methods to prevent herbicides from becoming "phytotoxic agents". When applying herbicides, especially broad-spectrum herbicides, the wind direction should be observed, and a windshield should be installed on the nozzle to avoid harming the crops of the adjacent field, and at the same time, the medicine should be thoroughly washed before it can be used to apply other pesticides. Take care to avoid the use of pesticides that have residual phytotoxicity to the crops.

FAG Bearing
Before using,you can make a single judge by observing,touching & easily testing.
Does it look glossiness?Does it feel smooth?Does it make any noise?
A high quality Deep Groove Ball Bearing must be hypefine grinded with smooth surface, no burrs on the edges,running fast &noiseless, that is the feature of our products.

Deep groove ball bearings are the most widely used bearing type and are particularly versatile.
They have low friction and are optimized for low noise and low vibration which enables high rotational speeds.They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing
types.
