• Apply these products using label approved nozzles at manufacturer’s recommended spray pressure listed on the label. Use the minimum boom height based on the nozzle manufacturer’s direction.
  • Do not apply at wind speeds greater than 15 mph.
  • Do not apply under temperature inversion conditions.
  • Do not substitute water with nitrogen solutions as spray carrier.
  • Apply at label required application rates.
  • Only apply with approved tank-mix products

No

Do not apply 2,4-D products when inversion conditions exist. The following are indicators of the presence of temperature inversion conditions:

  • Calm day with wind speed less than 3 mph;
  • Clear night;
  • Dust cloud hanging on the side of the road;
  • Dew or frost present on the ground;
  • Horizontal smoke pattern;
  • Ground fog in low-lying area.

No

No, the labels prohibit 2,4-D application if the wind is blowing toward susceptible plants listed on the label.

Can I apply new 2,4-D products when the wind is blowing in the direction of susceptible plants?

No, the labels prohibit 2,4-D application if the wind is blowing toward susceptible plants listed on the label.

No

Commercially grown tomatoes, and other fruiting vegetables (EPA crop group 8), cucurbits (EPA crop group 9), and grapes are listed as susceptible plants on the new 2,4-D product labels.

No

The applicator must always maintain a 30 foot downwind buffer. To maintain the label required downwind buffer zone, the applicator must measure the wind direction prior to the start of any swath that is within 30 feet of a sensitive area. No application can be made in an area that is within 30 feet of a sensitive area if the wind direction is towards the sensitive area. Applicators can still use out-of-field non-sensitive crops and areas in the total buffer distance calculation. Follow all label requirements for the protection of sensitive areas.
