Thiamethoxam found to reduce thrip, pea weevil and pea aphid damage

A new seed treatment will aid pest control in vining peas, trials by the Processors & Growers Research Organisation (PGRO) have shown.

Syngenta's thiamethoxam (TMX) is best known in the sugar beet and oilseed rape sector, where it is marketed as Cruiser Force Sugar Beet Seed and Cruiser OSR.

Crops treated with the insecticide, which is now available for vining pea crops, tend to be better established and faster growing.

PGRO technical director Anthony Biddle said trials recorded reductions in thrip, pea weevil and pea aphid damage - leading to improved crop nodulation.

A further benefit from TMX was good control of bean seed fly in late-planted vining peas. The pest can lead to complete crop loss.

The end result in the trials where TMX was co-applied with Wakil was an average yield increase across all early drilled varieties of almost 50 per cent over Wakil on its own.

"Weevil control is difficult to achieve with pyrethroids, which need to be applied before egg-laying to be effective," said Biddle. "Fifty per cent control is the best that can usually be expected. In contrast, TMX treatment gave a visible benefit that lasted all the way through the season. Weevil and thrip numbers were considerably reduced, giving almost complete control.

TMX brought a large increase in the number of root nodules because the pea and bean weevil larvae were prevented from getting into the soil.
