Benefits of Versys
- Versys insecticide has a new, unique mode of action known as chordotonal organ TRPV channel modulators.
IRAC Group 9D. - The chordotonal organs are biological stretch sensors.
They may be located in the antennae, mouth, legs, wings or thorax of insects. - These stretch sensors provide insects with their senses of hearing, orientation and balance.
In insect leg joints, the same sensors are critical for coordinated movement. - Versys acts selectively on these stretch sensors making it impossible for the insect to detect sound, gravity and the movement and position of body parts.
- Deaf, disoriented and uncoordinated, insects affected by Versys rapidly cease feeding.

Application Tips
- Ensure thorough and uniform coverage by using higher water volumes.
- Do not apply during periods of dead calm or when winds are gusty.
- Do not make more than two sequential applications of Versys insecticide before using an effective insecticide with a different mode of action.
Water volume
Ground application
40 L/ac (10 gal/ac) minimum (ensure thorough coverage)
Mixing order
1. Fill clean spray tank 1/2 full of clean water and start agitation.
2. Add the correct amount of Versys 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.
Pre-harvest interval

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
