Cleared chemicals not suggested for Florida. PCP or Pentachlorophenol. Available from several suppliers. Cleared at 4.5 Penta Ib/A when used preemergence to 'cane at 1 to 2 days after planting. Cleared at same rate for directed postemergence sprays before weeds are 2 inches tall. NaPCP or Sodium salt of pentachlorophenol. Available from several suppliers. SPCP Cleared at 44 lb/A preemergence immediately after planting and before weed seedlings emerge. A rate-of 10 1/2 lb/A is cleared for use immed- iately after weed seedlings emerge. Simazine 2-chloro-4,6-bis(ethylamino)-s-triazine. Geigy "Simazine 80W", an 80% wettablee powder. Application rates and conditions similar to Atrazine. NaTCA or Sodium salt of trichloroacetic acid.. Available from many suppliers in STCA, formulations containing about 80% TCA equivalent. Cleared at 31.7 lb/A for pre- and.early postemergence and at 45 Ib/A acid equivalent as late postemergence directed sprays at base of 'cane plants. 2,4,5-T As given above. Cleared at 4.5 lb/A acid equivalent for preemergence use in Hawaii only. SHORT GLOSSARY OF HERBICIDE TERMINOLOGY Band application Using the herbicide in a narrow, continuous strip in, over or along the crop row rather than over the entire field. Broadcast application Using the herbicide over an entire field or area. Contact herbicide An herbicide that kills primarily by direct contact with plant tissue rather than by translocation within the plant. Directed application Using an herbicide in a restricted location such as the crop row or bed at the base of plants to avoid wetting plant foliage. Overall application Applying an herbicide from directly above plants. Postemergence treatment Application after crop plants emerge. Treatments may also be specified as postemergence to weeds or both crop and weeds. Preemergence treatment Application after a crop is planted but before it emerges. Treatments may be specified preemergence to weeds or both crop and weeds. Treatments may be specified preemergence to weeds but postemergence to the crop. Usually, preemergence treatments are made before both crop and weeds emerge. Contact preemergence treatments kill emerged weeds by contact action and are applied before the crop comes up. Residual pre- emergence treatments kill weeds as their seed germinate or as seedlings emerge, either before or after crop come-up.: Preplanting treatment Application of an herbicide before planting a crop. USE CAUTION WHEN APPLYING 2,4-D and 2,4,5-T Chlorophenoxy herbicides are capable of causing severe injury to sensitive vegetable, fruit and ornamental cropsseveral miles from the actual spraying site. The degree of hazard in the use of these chemicals is related directly to the manner of application and weather conditions. Aerial application is most hazardous. Ground equipment should be operated with low spray volume and at low spraying pressure.
