  • Early treatment is also necessary to prevent crop loss.
  • Complete and thorough coverage of infested plants is necessary for good control.
  • With that in mind, control is generally more effective with liquid sprays than with dust applications.
  • Because of decades of repeated insecticide use, the Colorado potato beetle may be resistant to many available insecticides, including Sevin and malathion.

Look for products labeled for use on potatoes in the home garden and apply according to label directions, including spray early, spray often.

  2. Repeated and intensive use of insecticides against the Colorado potato beetle has lead to resistant to nearly all insecticides, including the common garden insecticide Sevin (carbaryl) in many areas.

Alternate chemical classes to delay resistance development. Spray insecticide from one class during May and June for the first generation and then switch a different class during July and August for the second generation.
