The reasonable preparation of the concentration of some non-wettable or difficult to wet powder, should first add a little water, the liquid into a paste, and then add water to use. Selecting the right spraying time for the fungicide spraying too early will cause the waste of the medicine or reduce the efficacy. If it is too late, it will cause a large number of pathogens to invade the host and cause harm. Therefore, the time for the application of the fungicide should be before the onset of the disease (preservation of the drug) or early onset ( It is better to take preventive measures. Master the number of medications is usually sprayed once every 10 to 15 days, a total of 2 or 3 times. In case of special circumstances, such as rain after application, it should be sprayed once. Avoidance of drug resistance In order to avoid disease resistance, it is necessary to scientifically use fungicides based on the actual use of alternating (rotary) uses of different types of pharmaceuticals, such as the use of a combination of systemic agents and traditional fungicides. The quantity of drugs used to improve the quality of medications should be appropriate. Too many drugs on the one hand will increase the cost, and on the other hand, it may easily cause injury. However, if the use of drugs is too small, all parts of the plant cannot be protected. The quality of medication should be emphasized. When spraying, it is required to have dense fog and uniform spraying. It is necessary to spray the front and back of the stem and the leaves of the plant so as to avoid leakage.
Laser distance measure is a very convenient
tool for various types of applications in industries, construction and house decoration.
Laser distance meter is a very useful device which gives accurate measurement
of distance, area and volume especially in large areas such as rooms,
apartments, buildings, real estates, factories, warehouses, infrastructures, gardens,
roads, and many other applications requiring accurate results for distance ,
area and volume measurement.
Trade your heavy tape measure for laser
rangefinder, which let you simply take measurements with one hand. No matter
your job, the laser rangefinder will help you measure much farther, with
greater accuracy and in more situations, saving you money and time.
