Movento® in cotton helping farmers to reach new levels of defence against aphids and silverleaf whitefly

Melbourne, 1 March 2011 – The recent registration of Movento insecticide in cotton has provided Australian growers with an even more effective tool to combat aphids and silverleaf whitefly and, at the same time, addresses chemical resistance which is a growing concern in the control of these pests.

The unique ability of Movento to be transported throughout the whole plant gives growers greater opportunity to defend their crops and take control of pests.

“While traditional systemic insecticides are transported through plants in one direction, Movento is two-way systemic – it moves upwards and downwards throughout the entire plant system, giving it protection from leaf to leaf and back down from leaf to roots,” says Sarah Wilson, Technical Advisor from Bayer CropScience.

“As a consequence, the redistribution of Movento around the plant eliminates the problem of unprotected areas where pests can run and hide,” Sarah adds.

Protecting against aphid and sliverleaf whitefly in cotton
On farm, many cotton farmers with crops suffering attacks from cotton aphids and silverleaf whitefly on their crops find Movento is particularly effective in controlling the pests as they feed on treated plant sap.

Richard Ross, Farm Manager at Cooinda Cotton at St George, Queensland says, “We first used Movento insecticide from Bayer CropScience on our onion crops to control thrips.

“It worked so well we decided to try Movento on our cotton crops to control aphids and silverleaf whitefly.

“The combination of the systemicity and the residual effect were definitely contributing factors in our decision to use the product.

“Using Movento was quite cost-effective as you could use a single application and avoid further costs as the systemic action is persistent which made it an attractive option.”

In fact, Movento is strongly compatible with an integrated pest management (IPM) approach and does not have significant adverse effects on the majority of beneficial species.

“This is particularly important because of the propensity for some broad spectrum insecticides to induce problems due to their detrimental effect on natural enemies,” explains Sarah.

Speaking on the issues associated with aphid and silverleaf whitefly, Susan Maas, Cotton Extension Officer for the Department of Employment, Economic Development and Innovation Agri-Science Queensland said that resistance was a big concern for the industry.

“Consecutive applications of the same insecticides can lead to resistance, and species like cotton aphids and silverleaf whitefly are able to develop resistance to certain chemicals quite quickly,” Ms Maas says.

“It is therefore important that growers and consultants use the aphid and silverleaf whitefly thresholds and follow the IRMS [Insect Resistance Management Strategy].”

Brad Cogan, an agronomist in the Gwydir and MacIntyre regions, comments, “The fact that Movento has a new mode of action and helps with resistance management is a massive plus, particularly with aphid resistance.”

Mr Ross agrees and says, “We prefer softer options and Movento fits well into our operations from an IPM perspective.”
