  3. If tank mix is being applied, add the correct amount while continuing agitation.
  4. Clean the spray tank after use.

Application Tips

Ensure thorough and uniform coverage by using higher water volumes.

A plant-back interval of 30 days is required for all crops not on the label.

Resistance Management Recommendations

  • Insecticide use should be based on an IPM program that includes scouting and record keeping, and considers pest thresholds, as well as cultural, biological, and other chemical control practices
  • Before using an insecticide, correctly identify the pest and monitor population levels in the crop. Only treat if action thresholds (i.e., pest numbers or damage level) are met or if forecasting models expect them to be met
  • Where possible, rotate the use of insecticides with different insecticide groups that control the same pests
  • DO NOT exceed the total number of applications of insecticide per year
  • Use tank mixtures with insecticides from a different group that are effective on the target pest when such use is permitted
  • Monitor treated pest populations for resistance development
  • If you suspect resistance, contact BASF or your local extension specialist
