What wind speed is safe for spraying?

Spraying when the wind speed is between 1.2 and 6 mph is the optimum window with ideal spraying conditions between 2 and 4 mph. Above this, there is a high risk of spray droplets reaching neighbouring fields and crops. Conversely, below this there is the danger of temperature inversions occurring.

How windy is too windy to spray crops?

Always follow label information, although generally, wind speeds of 3 to 7 miles per hour (mph) are preferable. Spray at low wind velocities (less than 10 mph). If wind speed or direction changes during an application, immediately adjust the buffer size or location or stop the application.

What wind speed is too high for spraying?

specify 10 MPH as the maximum wind speed for application. Spraying when winds exceed label restrictions is not only illegal, but can override steps taken to eliminate off-target movement (e.g. low-drift nozzles, low spray pressure, etc.).

Can you spray in the wind?

How Windy Can You Spray? Before, during, and after the application, always check the wind speed and direction. It is always a good idea to follow label information, but generally, wind speeds of 3 to 7 miles per hour (mph) are preferable. Wind speeds of less than 10 mph are ideal for spraying.

Why spraying on a windy day should be avoided?

Do not spray if wind speed and direction would cause drift onto sensitive areas.

Can you spray weeds on a windy day?

Never spray when it’s too windy or when the wind is blowing towards nearby sensitive plants. If you are spraying close to the ground and not using excessive pressure, a light breeze shouldn’t be a problem. However, stronger winds will cause the spray to drift.

Can you spray Roundup on a windy day?

You should not apply Roundup when its windy. The drift or contact with treated leaves may damage plants you want to keep. Although Roundup Gel can overcome this problem as its formulation allows it to stick to the leaf without the risk of spray drift.

How do you spray in windy conditions?

Tips for spraying in the wind

  1. Use low-drift nozzles.
  2. Find a nozzle that can achieve a coarse spray at a broad range of pressures.
  3. Aim for 100% overlap nozzle to nozzle.
  4. Keep your boom low to reduce drift.
  5. Maintain reasonable travel speeds.
  6. Let the weather help you.
  7. Talk to people who might be affected.

Can you spray pesticides in wind?

Before spraying Do not spray if wind speed and direction would cause drift onto sensitive areas. Ideal spraying conditions are a Force 2 light breeze (3.2-6.5 km/h) blowing away from sensitive areas. This would be a breeze strong enough to be felt on the face and to rustle leaves (see table below).
