Cost benefit of using Bt-based productsin IPM programs

23 October 2007

Benefits of using Bts:

– Effective control of many lepidopteran pests–armyworm, loopers, fruitworm, cabbage worm diamondback moth

– Unique MOA– Conserve beneficial insects– Favorable environmental attributes– Minimal re-entry restrictions– Organic status– Minimal pre-harvest restrictions– Minimize crop damage and maximize ROI

Target: IPM programs in cole crops and tomato

Achieve IPM ObjectivesControl lepidopteran pests while • reducing the total standard insecticide applications• conserving the beneficial insects• providing a sustainable cropping system

Bt-based products in IPM programs

23 October 2007

Goal: develop field data to demonstrate the benefits of using DiPel and XenTari in season-long pest-control programs with standard insecticides:

• improved efficacy

• enhanced yields and crop quality

• reduced cost

• reducing the threat of resistance to standard insecticides

Bt-based products in IPM programs

23 October 2007

Approach 1: Rotation program utilizing DiPel (or XenTari) with Standard Insecticides (SI)

• Scout fields for pest; apply products at “action threshold”• When non-lepidopteran pests are present apply a traditional insecticide (TI) as needed

Result

Not Tested

23 October 2007

• Insect Control:

• DiPel/XenTari used in tank-mix and rotation treatments highly effective against diamondback moth, armyworms, loopers and others

• DiPel/XenTari used in tank-mix or rotation treatments were generally equal to or better than soft chemistries alone

• Tank-mix treatments usually more effective than rotational treatments

Conclusions

23 October 2007

• Cost/Yields:

• Tank-mix treatments most costly but more effective

• Cost of rotational treatments much less for the same level of control.

• Yields from DiPel/XenTari tank-mix and rotational treatments comparable to soft chemistries alone.

Conclusions

23 October 2007

• New Market Space

• Well-designed and well-executed replicated field trials demonstrated the efficacy and cost benefits of DiPel/XenTari in tank-mix and rotational treatments with soft chemistries

• New market space was created
