USE OF PESTICIDES 



This publication is intended for nationwide 

 distribution. Pesticides are registered by 

 the Environmental Protection Agency 

 (EPA) for countrywide use unless otherwise 

 indicated on the label. 



The use of pesticides is governed by the pro- 

 visions of the Federal Insecticide, 

 Fungicide, and Rodenticide Act, as 

 amended. This Act is administered by EPA. 

 According to the provisions of the Act, "It 

 shall be unlawful for any person to use any 

 registered pesticide in a manner inconsis- 

 tent with its labeling." (Section 12(a) (2) 

 (G)) 



EPA has interpreted this Section of the Act 

 to require that the intended use of the 

 pesticide must be on the label of the 

 pesticide being used or covered by a 

 Pesticide Enforcement Policy Statement 

 (PEPS) issued by EPA. 



The optimum use of pesticides, both as to 

 rate and frequency, may vary in different 

 sections of the country. Users of this 

 publication may also wish to consult their 

 Cooperative Extension Service, State 

 Agricultural Experiment Stations, or Coun- 

 ty Extension Agents for information ap- 

 plicable to their localities. 



The pesticides mentioned in this publica- 

 tion are available in several different for- 



mulations that contain varying amounts of 

 active ingredient. Because of this 

 difference, the rates given in this publica- 

 tion refer to the amount of active ingre- 

 dient, unless otherwise indicated. Users are 

 reminded to convert the rate in the publica- 

 tion to the strength of the pesticide ac- 

 tually being used. For example, 1 pound of 

 active ingredient equals 2 pounds of a 50 

 percent formulation. 



The user is cautioned to read and follow all 

 directions and precautions given on the 

 label of the pesticide formulation being 

 used. 



Federal and State regulations require 

 registration numbers on all pesticide con- 

 tainers. Use only pesticides that carry one 

 of these registration numbers. 



USDA publications that contain sugges- 

 tions for the use of pesticides are normally 

 revised at 2-year intervals. If your copy is 

 more than 2 years old, contact your 

 Cooperative Extension Service to determine 

 the latest pesticide recommendations. 



The pesticides mentioned in this publica- 

 tion were federally registered for the use in- 

 dicated as of the issue of this publication. 

 The user is cautioned to determine the 

 directions on the label or labeling prior to 

 use of the pesticide.

3 These pesticides, although toxic to bees 

 as foliage residues or contact poisons, are 

 not toxic to honey bees when applied as gra- 

 nules on or in the soil. 



4 Mevinphos (Phosdrin*),naled (Dibrom*), 

 and tepp have short residual activity and 

 kill only the bees contacted at time of treat- 

 ment or shortly thereafter. They are usually 

 safe to use when bees are not in flight; they 

 are not safe to use around colonies. 



5 Usually, dosages of sabadilla are low 

 enough to be no problem. Sabadilla should 

 not be applied to open flowers that are 

 freely visited by bees.
