Abstract:
The effects of 2,4-D and related compounds on plants and animals, including information concerning the sensitivity of plants, physiological action of the herbicides, characteristic appearance of affected plants, and methods of determining the herbicide on the plant are presented. 2,4-D being the most characteristic compound of the group is discussed in greater length. It exerts its great est effect in the rapidly growing and differentiating plant tissues. Cotton is the most sensitive major crop in the Northwest Florida area. One ounce of 2,4-D evenly distributed over 35 acres will seriously injure a cotton crop. For this reason, extreme care should be taken during all herbicide spray operations and especially when such chemicals as 2,4-D, Silvex and Falone are applied adjacent to cotton fields. The use of mist-blower applicators should be limited to only those cases when complete meteorological data and other information pertinent to drift control are available and indicate absolute safety. Grasses being fairly tolerant to 2,4-D are not injured by a dosage of 1 lbacre. Tolerance of other crops is given. Six methods are given for the extraction of herbicide from a sample of foliage. The characterization of the compound is then accomplished with a gas chromatograph. Author
