Introducing Zivalgo: A New Insecticide in the U.S.
Farmers in the United States now have access to a newly launched insecticide called Zivalgo, which is based on the active ingredient isocycloseram. This product belongs to an entirely new chemical class of insecticides, providing contact control across all life stages of the Colorado potato beetle. It is particularly effective against the summer generation of adult beetles, but also targets leafhoppers, thrips, and flea beetles.
Experts recommend applying the maximum allowed dosage rates for optimal results. While Zivalgo can be applied via aerial spraying, ground-based spraying often yields better outcomes. It is important to note that insecticides from this chemical group should not be used more than three times within a single generation of the Colorado potato beetle, or more than three times within a 30-day period. Additionally, the product is toxic to pollinators, so its use during potato flowering is prohibited, although exceptions may be possible under specific weather conditions and time restrictions.
The Critical Role of Novel Modes of Action
Professor Zsofia Szendrei from the Department of Entomology stated: 'Adding new modes of action is crucial for resistance management, as the Colorado potato beetle has a long history of developing resistance to insecticides.'
This statement underscores the importance of new chemical tools in managing pests that have become resistant to traditional insecticides.
In summary, the introduction of Zivalgo could significantly ease the challenge farmers face in controlling the Colorado potato beetle and other pests. However, its use requires strict adherence to guidelines and restrictions to protect bees and other beneficial insects.
Given the growing resistance of the Colorado potato beetle to conventional control methods, this new insecticide may become a vital resource for agricultural producers dealing with this persistent pest. The rollout of Zivalgo opens up fresh possibilities for effective pest management, but its application must be carefully regulated to avoid harming the ecosystem—especially pollinators, which are essential for agricultural production.
