They are that: . the use of a spray additive not recommended on a product label would be considered in the same light as not following the recommendations, and the manufacturer would not accept responsibility for the results. a surfactant will not improve the performance of a pre-emer- gence or pre-plantincorporated herbicide. The physical properties of the spray mixture may be improved by the addition of a surfactant if problems have been encountered in mixing or spraying,but it will not improve the weed kill. herbicide formulations intended for plant foliage application (2,4-D, Banvel) already contain surfactants which have been designed and formulated for that particular herbicide. The addition of another surfactant is unlikely to improve the herbicide's performance against weeds, but could increase its effect on the crop and cause some injury. - 30 - 20.
