WHAT’S NEW
Vayego® 200SC Insecticide A new tool for apple growers to control codling moth, leaf roller caterpillar and bronze beetle. With a brand-new registration, the Bayer insecticide Vayego is now available to Pipfruit growers.
Vayego 200SC is a liquid formulation containing the active ingredient tetraniliprole, a Group 28 Diamide insecticide which is an active ingredient new to the Pipfruit industry. With over 4,000 trials performed globally, as well as a rigorous trial program in New Zealand, Vayego has demonstrated excellent efficacy across the lepidoptera and coleoptera species targeted. These trials have shown that Vayego has some attractive properties that contribute to its versatility, safety, strength and performance. One of which is the fact that it is active on all three of the life stages of codling moth, from eggs to adults. While the main control comes from larval ingestion, eggs can also be affected if laid on treated leaves and fruit, or if they have already been laid and are then treated with Vayego. Rapid feeding cessation is also a feature giving strength to codling moth control. Larvae lose muscle control, become immobile and cease feeding immediately after application, giving the benefit of less damaged fruit. Vayego is also locally systemic which ensures distribution throughout the leaf, helping to maximise coverage. “A further feature Pipfruit growers will find beneficial is the label claim for bronze beetle control,” Marc adds. “Efficacy was proven by Plant & Food Research in bioassay work, before being backed up by field trials over the last few years. As a third string to its bow, this makes Vayego a very versatile option for pest control for Pipfruit growers.” Vayego is recommended to be used from seven days post petal fall through to early December at a rate of 15 mL/100 litres of water as a dilute spray to the point of runoff. If concentrate spraying is used, then the rate must be adjusted accordingly.

For best practice resistance management, it is important that Vayego is used as part of a seasonal pest control programme that incorporates other chemistries with different modes of action. Marc says “resistance management guidelines state that Vayego should only be applied to one generation of codling moth. By targeting the petal fall to early December period, Vayego will only be applied to generation one, which fits into the recommended guidelines, and will protect insect management for the future.” Over many years of trials, Vayego has also shown a high level of crop safety, both when applied on its own or when combined with a wide range of tank mix partners. 100 80 Mortality (%)
“Providing excellent efficacy against codling moth, leaf roller caterpillar and bronze beetle, Vayego offers a new versatile and flexible option for growers to incorporate into their seasonal pest management programme,” says Marc Fox, horticulture market and territory manager for Bayer.
