This summer, Crop Care has a new insecticide - Endgame 500WG - registered for aphid control in stonefruit, potatoes and brassicas.
As a different chemical group (Group 9B) Endgame provides a valuable alternative insecticide for resistance management.
Announcing the product’s recent registration, Crop Care’s regulatory affairs manager Bronwyn Vorpagel said the active ingredient pymetrozine was a specific aphicide that disrupted the insects’ feeding.
“Rather than having a neurotoxic effect, it has a very specific anti-feeding mode of action.
“Aphids treated with Endgame simply cease feeding, usually within a short time of treatment, and ultimately starve to death.
“It inhibits feeding without any neurotoxic signs, so aphids may remain but are unable to feed.”
Ms Vorpagel said that Endgame was a valuable, novel insecticide for controlling these serious sucking-insect pests.
She said Crop Care had commissioned trials in 2012 in southeast Queensland and central NSW to demonstrate the activity of Endgame on a number of aphid species across a range of crop types.
“In the trials conducted against black peach aphid in peaches, Endgame provided very good control, similar to or better than other standard aphicides.”
Endgame has been registered to control both green peach and black peach aphid in stone fruit.
To aid in aphid resistance management, Ms Vorpagel said that no more than two applications of Endgame (or other Group 9B insecticides) should be applied per crop, and as non-consecutive sprays.
