WEED CONTROL IN PASTURES WITH oAI'D SDIL5 IN i-'. L.L.'. L:.

 The following chart lists the plants which often are undesirable species

in native and improved pastures in central Florida. Also shown are the

herbicides, plant response to these chemicals and literature references giving

materials which are currently accepted as controlling agents for the species.

Rates per acre of herbicide, volume of carrier agent and method of application

are not given because weed maturity, season of year, proximity to desirable

crops and climatological factors must be considered. Herbicides other than

those listed also may result in satisfactory control in many circumstances,

and may be even more desirable when the many factors involved are given full

consideration. It is beyond the scope of this paper to list all herbicides

available or effective in controlling these plants. Study of the references,

the Southern Weed Conference Proceedings in particular, will result in a

fuller understanding of the trials and materials which are being tested and

suggested for control of specific plants. The percentage plant kill, or

control, which is satisfactory varies with plant species and management

programs. In pastures 100 percent control may be unnecessary and excessively

expensive.

 The list of noxious pasture plants in pastures on sandy soils in peninsular

Florida which can be controlled with herbicides has increased each year since

World War II. Experiments must be continued to improve the effectiveness of

use of herbicides now available and to evaluate new compounds. This will help

to meet the greater demands for agricultural products and to combat the

constantly shifting weed populations which result from an intensified control

program. .
