<br />wind pat[ems. Every applicator should be familiar with local wind panems and
<br />how they affect spray drift
<br />Temperature And Humidity: When making applications in low relative humid-
<br />ity, set up equipment to produce larger droplets to compensate for evaporation.
<br />Droplet evaporation is most severe when conditions art both hot and dry.
<br />Temperature Inversions: Applications should not occur during a temperature
<br />inversion because drift potential is high. Temperature inversions restrict vertical
<br />air mixing, which causes small suspended droplets to remain in a concentrated
<br />cloud. This cloud can move in unpredictable directions due to the light variable
<br />winds common during inversions. Tempemmre inversions ere characterized by
<br />increasing temperatures with altitude and ere common on nights with limited cloud
<br />cover and light to no wind. They begin to forte as the Sun sets and often continue
<br />into the morning. Their presence can be indicated by ground fog; however, if fog
<br />is not present inversions can also be identified by the movement of the smoke
<br />from a ground source or an aircraft smoke generator. Smoke that layers and
<br />moves laterally in a concentrated cloud (under low wind conditions) indicates an
<br />inversion, while smoke that moves upward and rapidly dissipates indicates good
<br />vertical air mixing.
<br />Sensitive Areas: The pesticide shouhl only be applied when the potential far
<br />drift to adjacent sensitive areas (e.g., residential areas, bodies of water, known
<br />habitat for threatened or endangered species, non-mrget crops) is minimal (ag.,
<br />when wind is blowing away from the sensitive arcas).

<br />Non-Cropland Areas
<br />Use 7ordon 22K to control suscepdble broadleaf weeds and woody plants on non-
<br />cropland areas such as roadsides or other righuof--way, fence rows, end around
<br />fans buildings. Up to 2 quarts of Tordon 22K per acre may be applied. See [he
<br />Rangeland and Permanent Grass Pastures section for specific target weed or
<br />woody plant species treatment recommendatiaos.
<br />Rangeland and Permanent Grass Pastures
<br />Use Tordon 22K on rangeland and permanent grass pastures tv control susceptible
<br />broadleaf weeds and woody plants including, but not limited m those shown in
<br />the following tables. Many annual weeds at the seedling smgc can be controlled
<br />at the rate of 1 pt per acre. Where a rate range is recommended choose the higher
<br />rate for dense weed infestations, and for more dependable, longer lasting control.
<br />Lower rates will perform beat when applied undo favorable conditions and at
<br />the optimum growth stage, but may provide a lower level of control and require
<br />fetreadnenC For but resul6 neat when weeds are small and ac[ivdy growing in
<br />the spring before full bloom, however, certain weeds may also be Heated in kk
<br />summer to fall Treatments during full bloom or seed stage of some weeds may
<br />not provide accepmble control.
