Bayer CropScience will introduce soon a new class of chemistry that will be an alternative to imidacloprid, the company’s embattled systemic insecticide that has been implicated in honey bee deaths.
The new active ingredient is flupyradifurone. It is a systemic from the butenolide chemical class and is active on sucking insect pests.
It will be registered in 2015 and marketed by Bayer under the trade name Sivanto™ as a “bee friendly” product with no bloom (application) restrictions.
Biological efficacy studies conducted within the U.S. since 2007 by internal and external scientists on an array of annual and perennial crops have shown high levels of efficacy against various species of aphids, leafhoppers, psyllids, scales, thrips and whiteflies.
A unique property of Sivanto is its strong and rapid feeding cessation effect from both soil and foliar applications. It is active via ingestion and contact. It is an adult knockdown product that controls nymph and egg stages.
It is both systemic for root uptake and translaminer from foliar applications. It has minimal impact on beneficials.
Submitted for global joint review in 2012, registration is being pursued on many annual and perennial crops.
The proposed label includes a four hour re-entry interval.
It is expected to be a major part of the Bayer CropScience insecticide package as an alternative to imidaclolprid.
