6 GENERAL DESCRIPTION:
The 2,4-D's are mainly foliar absorbed, post emergent herbicides for the control of broad leaved weeds.7 APPLICATION METHODS AND TIPS:
Varies depending on the formulation. See individual products.8 WEATHER:
The ester formulations are generally rainfast in 3 hours whereas the amines and salts generally take 6 hours to become rainfast.9 ADJUVANTS:
Wetting agents often used on hard to wet plants.10 WATER QUALITY:

DMA salt | Least tolerant | < 8 OK | Less tolerant | Tolerant |
IPA salt | Least tolerant | < 8 OK | Less tolerant | Tolerant |
TIPA salt | Least tolerant | < 8 OK | Less tolerant | Tolerant |
IPE ester | Less tolerant | Tolerant | May separate | |

Butyl ester | Less tolerant | Tolerant | May separate |
11 COMPATIBILITY:
Trace elements: Amine formulations are not compatible with many copper and zinc products. Ester formulations are generally more compatible providing the emulsifier is not overloaded and the product separates from the water (do a jar test).12 EQUIPMENT:

14 HERBICIDE RESISTANCE:
The formulation is only expected to have an indirect effect on the development of resistance due to some formulations being more efficacious on some plants than others.15 REPLANTING INTERVALS:
