New Insecticides for 2022!

Powered by three industry-leading technologies, Endigo® ZCX insecticide contains a novel, optimized formulation that provides both knockdown and residual control of a broad spectrum of insects, including pyrethroid-resistant pests and invasive species.

  • Contains two complementary modes of action, thiamethoxam and lambda-cyhalothrin, to provide robust, broad-spectrum control of key northern and southern soybean pests, including soybean aphids, Japanese beetles, bean leaf beetles, multiple stink bug species and some lepidopteran pests
  • Utilizes proven Zeon® Technology to help ensure fast pest knockdown, strong adhesion to the plant surface, improved rain fastness and longer residual activity
  • Controls populations of insects, such as soybean aphids and stink bugs, that exhibit tolerance or resistance to pyrethroids in some geographies
  • An excellent option for acres formerly receiving chlorpyrifos-based products, which can no longer be used effective Feb. 28, 2022 due to updated EPA guidance

When it comes to protecting your soybean crops, you can’t play the waiting game to see if you have pyrethroid-resistant aphids. What you need is an insecticide that works well and works fast against aphids and other chewing insects.

  • Fast-acting knockdown power paired with long-lasting residual control
  • Broad-spectrum control of soybean aphid, including resistant species
  • Two modes of action

And BASF’s new dual mode of action insecticide, Renestra™, does exactly that.

By combining traditional pyrethroid chemistry with Inscalis™ – the newest site of action available for soybeans – Renestra™ Insecticide is able to deliver fast-acting results on a broad spectrum of harmful insects while still providing long-lasting residual control for soybean crops.
 
And with its new dual mode of action, Renestra™ Insecticide is able to eliminate resistant and non-resistant soybean aphids in addition to other feeding insects. That way, farmers can always count on it to get rid of tough pests and to keep their crops protected for the long run.

Ridgeback™ insecticide gives soybean and corn farmers quick knockdown and long-lasting control of difficult-to-control pests. With 2 modes of action, Ridgeback insecticide has the power to fight soybean aphids, Japanese beetles, spider mites, and other pests — while helping you manage pest resistance.

Gain best-in-class control over a wide range of yield-robbing pests — including pyrethroid-resistant soybean aphids, beetles, lepidopterans, mites, and other insects. Ridgeback insecticide targets pests through both contact and ingestion, stopping feeding within hours of application.
With the unique mode of action of Isoclast® active, Ridgeback insecticide empowers you to defeat pests that are resistant to other chemistries, improving plant productivity and yield potential. Control even the pests on the underside of leaves with the translaminar movement of Isoclast active.
Ridgeback insecticide combines novel and trusted modes of action with both Isoclast active and bifenthrin. Manage pyrethroid-resistant aphids in one easy-to-use premix that serves as an excellent rotational partner for farm sustainability and resistance management.
