New control for rust in ryegrass seed crops excels

Published on 07/12/2022

Syngenta says the registration was an important step for arable farmers, offering a powerful management tool for two key yield limiting diseases in ryegrass seed crops, with the added benefit of a short, 14-day withholding period.
Feedback on field performance
has all been extremely positive, according to Paul Hassan, Syngenta technical services lead.
“Agronomists have indicated
that the control of rust has been exceptional and represents a new standard in rust control in ryegrass crops. This backs up our own trial results.”
“The short withholding period
of 14 days has also proven very helpful for farmers in terms of grazing re-growth or feeding straw to livestock.

“After a number of years in de
velopment we are really pleased to offer this product to farmers.”

Elatus Plus provides powerful
rust control by binding strongly to the leaf surface to give long-lasting, rainfast protection. It also binds to the pathogen target site to inhibit fungal germination, shutting down a potential infection at a very early stage of disease development.

“The product is best applied
at ear emergence and again at flowering in a preventative programme,” Hassan says.

“As a solo SDHI formulation,
Elatus Plus provides growers the flexibility to add the best mixing partner, such as prothioconazole or Amistar.

“But it can also be applied as a
solo treatment in a preventative programme in alternation with an approved non-cross resistant fungicide.”

Another key benefit of Elatus
Plus in ryegrass seed crops is endophyte safety.

“Long-term storage endophyte
safety tests have been conducted. The results show it has a high level of safety for endophytes in ryegrass seed, so growers can use it with confidence on sensitive novel endophyte varieties,” Hassan says.

In cultivars known to be sensi
tive to triazole fungicides, Elatus Plus can be applied alone in a preventative programme. But it must always be mixed with a triazole fungicide in situations where a curative fungicide is needed.

Elatus Plus is a Group 7 SDHI
fungicide containing 100 grams/litre of benzovindiflupyr branded as Solatenol technology in an emulsifiable concentrate formulation.
It should be applied at 750 ml per hectare.

For resistance management,
do not apply more than two applications of Elatus Plus (or any other SDHI) to a ryegrass seed crop per season.
