Apply ONLY during late evening, night, or early morning on blooming crops or weeds.

Amino Triazoje (amitrole)
2,4-D (alkanolamine salts)
2,4-D (butoxvethanol ester)
*
2,4-D (isopropyl ester)
Elgetol (dinitrocresol) 1.5 pt/100 gal or less)

*


Can be applied at any time with reasonable safety to bees.

Alar (daminozide)

Ammate (AMS)
Ammonium thiosulfate
atrazine
Avenge (difentoquat)
Banvel (dicamba)
Butoxone (2,4-DB)
Carbyne (barban)
Chloro IPC (chlorpropham)
2,4-D (butyl ether ester)
*
2,4-D (isooctyl ester)
2,4-D (sodium salts)
dalapon
2,4-DB
Desiccant (arsenic acid)
diquat
Endothall
Eptam (EPTC)
Ethrel (ethephon)
Goal (oxyfluorfen)
IPC (propham)
Karmex (diuron)
Kerb (pronamide)
Lasso (alachlor)
MCPA
Monobor-Chlorate
NAA (naphthaleneacetic acid)
paraquat
Roundup (glyphosate)
Sencor (metribuzin)
Silvex (2,4,5-TP)
Sinbar (terbacil)
2,4,5-T
Tordon (picloram)
Treflan (trifluralin)

* There is field evidence that butyl derivatives of 2,4-D have a long-term chronic toxicity to bees, especially in cool climates and when nectar forage plants are treated.




CAUTION: Timing of insecticide applications in respect to bee poisoning hazard can be drastically modified by abnormal weather conditions. If temperatures are unusually low following treatment, residues on the crop typically remain toxic to bees about twice as long as during reasonably warm weather. Conversely, if abnormally high temperatures occur during late evening or early morning, bees may actively forage on the treated crop during these times.

!Warning. Use pesticides with care. Apply them only to plants, animals, or sites listed on the label. When mixing and applying pesticides, follow all label precautions to protect yourself and others around you. It is a violation of the law to disregard label directions. If pesticides are spilled on skin or clothing, remove clothing and wash skin thoroughly. Store pesticides in their original containers and keep them out of the reach of children, pets, and livestock.
