Soybean Aphids: Help Control What Others Can’t

3 Key Takeaways From This Article:

  • With increasing pyrethroid resistance, Transform® WG insecticide provides growers with another tool for soybean aphid control.
  • To maximize insecticide efficacy, recommend your grower-customers treat at a threshold of 250 aphids per plant.
  • Eight new crops, including corn and alfalfa, are on the expanded label for Transform® WG insecticide, and the previously labeled use for soybeans and cotton are restored.

Exploding soybean aphid infestations can slash potential yield in half. You need a control solution your grower-customers can depend on.

Transform® WG insecticide effectively controls soybean aphids even in high-pressure situations with pyrethroid-susceptible and pyrethroid-resistant populations.

Corteva Agriscience and university cooperators have conducted a decade of research demonstrating the high level of efficacy of Transform. In recent years (2016-2019), as pyrethroid-resistant aphids established and spread, 10 field trials were conducted. Soybean aphid counts taken six to eight days after treatment dropped from above threshold numbers (>250 aphids per plant) to an average of 17.8 aphids per plant with Transform as compared with 589.1 aphids per plant in the untreated plots.1

The new and distinct mode of action Transform provides plays a pivotal role in efforts to inhibit the increasing occurrence of insect resistance to current insecticides. Transform gives soybean growers a viable and effective alternative for soybean aphid control.
