Kestrel 3500 Delta T Pocket Wind Meter - Scottech.

Maximum wind speed for spraying

Wind Speed. When the wind speed was doubled, there was almost a 70% increase in drift when the readings were taken 90 feet downwind from the sprayer. Spray when the wind speed is 10 mph wind or less Boom height. When the boom height was increased from 18 to 36 inches the amount of drift increased 350% at 90 feet downwind.

Maximum wind speed for spraying

High wind. A wind of such velocity that one or more of the following hazards would be present: 1.The wind could blow an employee from an elevated location, 2.The wind could cause an employee or equipment handling material to lose control of the material, or. 3.The wind would expose an employee to other hazards not controlled by the standard.

Maximum wind speed for spraying

When spraying a typical field crop or grassland, the wind speed at the correct height of the nozzle (an important factor affecting drift) will be roughly half the value measured at 10 metres. If there is no crop (for example, when spraying hard surfaces in amenity areas) the wind speed at the height of the nozzle may be more than half of the value at 10 metres above the ground. As wind speed.

Maximum wind speed for spraying

It can record the minimum, maximum and average wind speeds. The humidity range is from 20 to 80% and has modes for instant, minimum, average and maximum and dew point measurements. The design of the propeller means that it is not sensitive to the wind direction and does not need to be directed precisely to get an accurate reading. We highly.

Maximum wind speed for spraying

There is a table in the PPP Code which provides a guide to wind speed and when spraying should take place. Buffer Zones and LERAPs. When spraying near water with certain pesticides, it might be necessary to leave an unsprayed strip of crop at the margin to prevent spray drifting out of the treated area. This unsprayed area is called a buffer zone. The product label (and approval) gives details.

Maximum wind speed for spraying

The safety of crop spraying is reliant on measurements of relative humidity, wind speed and wind direction, these measurements are also critical for maximising the effectiveness of the spraying process. This is also a heavily regulated area with many regions specifying maximum permitted wind speed when spraying to minimise spray drift.

Maximum wind speed for spraying

Many locales regulate the maximum permitted wind speed during spraying to minimize spray drift. The Kestrel 3500 DT is the difference between wet bulb and dry bulb temperatures. Its an accurate predictor of chemical evaporation rates.

Maximum wind speed for spraying

The maximum wind speed at the surface can not exceed the highest wind speed at 850 mb. Wind forecast is important for spraying chemicals and fertilizer application. Harvesting efficiency increases under calm conditions. In view of the anticipated windy condition, irrigation is avoided, otherwise lodging of the crop plants takes place. Generally stable weather conditions prevail in the morning.

Maximum wind speed for spraying

Maximum spray deposit was obtained 66.1 mg cm(-2) at sprayer speed of 2.1 km h(-1) and minimum deposit was obtained 37.1 mg cm(-2) at sprayer speed of 7.7 km h(-1). The results showed that the.

Maximum wind speed for spraying

The Kestrel 3500 Delta T meter allows you to accurately assess acceptable spraying conditions to ensure you're within guidelines and help you select the right spray nozzle. (Delta T is the difference between wet bulb and dry bulb temperatures. It's an accurate predictor of chemical evaporation rates). No other pocket weather meter offers this level of accuracy to arable farmers.
