2,4-D (Weedar 64, Orchard Master, Amine 4, Saber, 2,4-D Amine 4)
2,4-D is a postemergent herbicide used to control broadleaved weeds. 2,4-D products are not effective on grasses. They are particularly useful for controlling annual and perennial broadleaved weeds that escape preemergence treatments. Do not apply 2,4-D compounds to bare ground or under hot, dry conditions. Exercise extreme caution if using these materials in fields adjacent to growing grapes. Applications made early in the spring or postharvest will give the best results. Use only low-volatile formulations and do not use ester formulations of 2,4-D, as plant injury can occur due to vaporization. Symptoms of 2,4-D damage to both target weeds and nontarget plants include a downward cupping of the leaves and a twisting of the growing stem. Observe restrictions on days-to-harvest limitations as stone fruits and pome fruits have different limits. Growers are also cautioned that some 2,4-D materials are not registered on all tree fruit crops. Be sure to check the label to see if the material you have is labeled for the crop to which you intend to apply it.
