Evvos OneSense Agriculture UC15 – Spraying Solution
OneSense Agriculture UC15 includes:
- relative humidity and temperature sensor with solar radiation shield
- anemometer (wind speed sensor)
- rain gauge
- battery-powered wireless data transmitter (no solar panel needed)
- 1-year connectivity license
- 1-year CIS (cloud integration services) subscription
Use this kit to accurately monitor relative humidity, temperature, wind speed and rainfall and send the sensor data to your cloud portal or application, eliminating unnecessary trips to the field.
Weather conditions can have a direct impact on the effectiveness of spraying applications. It is important to measure variations in conditions within a field to prevent the application of excess fertiliser over the same areas.
Rain can have both a positive and a negative effect on spraying. Some products work best when rain water carries them into the soil after application, but not far enough to enter the water table before they do their work and break down. Rain too soon after application may also wash the product from leaves and reduce the level of protection.
With all the pressure to get started planting, spraying or harvesting, it is important to take the time to ensure you are setting your crops up for success.
- Spray when temperatures are low and relative humidity is high. In general, do not spray when relative humidity is less than 40% and air temperature is above 25°C. This reduces the chance of drift due to temperature inversions or evaporation. It also increases target deposition and coverage.
- Hot and dry conditions increase drift because droplets rapidly evaporate and become fine droplets, vapour or particles of concentrated pesticide.
- Optimum spraying conditions are early mornings following overcast nights. However, the best time to spray to avoid disrupting bee activity is evening or at night.
- Wind direction determines whether droplets travel toward the target or toward unintended downwind areas such as open water, sensitive crops or areas of human activity. Wind speed affects the distance a droplet will travel before it is deposited on the target.
- Monitor your weather parameters and understand the impact on the product being applied.
- Avoid spraying when foliage is still wet from rain or dew unless indicated by the label. A leaf can only retain a limited volume of spray, and therefore a limited amount of product.
- Once wetted, deposition will not increase beyond the tank concentration and the surplus will run off to the lower leaves and onto the soil.
