Suggestions on Pesticide Application:

  • Cover foliage uniformly, including undersides of leaves; improper application of the material to foliage results in poor insect and disease control.
  • The use of spray adjuvants (additives) may improve the performance of pesticides in some cases. Adjuvants sometimes provide better distribution and retention of insecticides and fungicides on plant foliage. However, experimental results have been variable. Before use, read the label and follow directions. Also, refer to “Spray Adjuvants or Additives” below.
  • Use recommended amounts of pesticides per acre regardless of volume of spray used.
  • Use specific recommended pesticides to control specific pests.
  • Time spray applications according to recommendations for specific pests. Consider growing rate of the crop for new, unprotected foliage.
  • Regardless of the type of spray equipment used, avoid situations where pesticide drift may be a problem.
  • Do not spray when temperatures exceed 90°F. At high temperatures, oil-based sprays can burn plants.
