SYNGENTA and Dow Agroscience have both released new herbicides onto the market.

Talinor, Syngenta’s offering, is a selective broadleaf spray featuring Group C and Group H chemistries.

Dow has released Rexade, a broad spectrum herbicide, approved for use in triticale and non-durum wheat varieties.

Rachel Carson, product lead for selective herbicides with Syngenta, said there had already been sales of Talinor through Victoria’s Wimmera and Mallee regions.

She said the product was very good on Australia’s most damaging broadleaf weed, wild radish, but added its strength came in its control of two emerging problem weeds.

“In terms of bifora and fumitory, Talinor is top of its class,” Ms Carson said.

Both weeds are becoming more problematic, especially in Western Australia and South Australia.

The product features a mix of three chemical compounds, the new active ingredient bicyclopyrone, bromoxynil and cloquintocet-mexyl.

Ms Carson said used at label rates it would cost growers about $18.75 a hectare.

“It is going to be very useful, especially for growers in winter active rainfall zones,” she said.

Dow is equally effusive about its product.

 “Cereal growers can expect significantly enhanced weed control when using Rexade due to the addition of the Arylex active ingredient,” said Dow AgroSciences cereals marketing manager, Dan

Dixon.

“Rexade can be tank mixed with various other herbicides and has a wide window of application,” Mr Dixon said.

He said its major application would be in terms of combating early post-emergent grass and broadleaf weeds.

Species targeted include brome grass, phalaris and wild oats, whiel Mr Dixon said it would also help suppress resurgent annual ryegrass, barley grass and silver grass.

On the broadleaf front Rexade will also prove effective against bedstraw, bifora, chickpeas, deadnettle, faba beans, seedling fleabane, fumitory and lentils.

Mr Dixon said it had a wide window of application, between growth stages 13 and 31, which would provide flexibility for growers in terms of managing spray logistics.

Ms Carson said Talinor could be tank mixed and had a short plant-back requirement.

“It is four months plant-back for summer and nine months for winter,” she said.

She said Talinor had been used previously overseas , primarily in corn and sugar, before being adapted for Australian conditions.
