A lasting barrier that protects against aphids.

  • Quickly halts feeding, which reduces production losses and virus transmission
  • Extended control of aphids
  • Powered by Inscalis®, a unique mode of action that controls labeled aphid pests that have developed resistance to other insecticides
  • Effective tool in an Integrated Pest Management strategy with low impact on beneficial insects, including predatory and parasitic insects

Benefits of Sefina

  • Sefina is a chordotonal organ TRPV channel modulator
  • Sensory neurons send continuous and misleading signals
  • Brain can’t detect sound, gravity or body part movement / position
  • Rapidly stops feeding. Control via starvation/dehydration, Disorientation, Unusual leg extensions, Stilt-walking, Lack of coordination and Inability to climb

Water Volume



In potatoes and soybeans

Ground application
40 to 80 L/ac (10 to 20 gal/ac)

Aerial application
20 L/ac (5 gal/ac) minimum

1 Allow a minimum of 7 days between applications.
2 Do not make more than two sequential applications of Sefina insecticide before using an effective insecticide with a different mode of action.
3 Do not apply more than 1012 ml/ac (2.5 L/ha) per year.
4 Do not apply more than 162 ml/ac (0.4 L/ha) per year.

Mixing Order

  1. Fill clean spray tank 1/2 full of clean water and start agitation.
  2. Add the correct amount of Sefina and continue to agitate until mixed.
  3. If tank mix is being applied, add the correct amount while continuing agitation.
  4. Clean the spray tank after use.

Ensure thorough and uniform coverage by using higher water volumes.

Pre-harvest Interval

Brassica head and stem vegetables, cucurbits, fruiting vegetables, leafy vegetables, soybeans, tuberous and corm vegetables (including potatoes) and root crops.

2 months after application
All other crops not listed on label when the maximum seasonal rate is 162 ml/ac (0.4 L/ha).

4 months after application

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
