Spring Blackgrass Control

Broadway Sunrise* and GF-2070, introduced last autumn are proving their worth in the fight against grassweeds including blackgrass, ryegrass and wild oats; as well as broad-leaved weeds such as volunteer beans, speedwells and brome.

A farmer near Rochford in Essex reports excellent blackgrass control from a GF-2070 treatment last November. 

 

Dow AgroSciences’ cereal herbicide specialist Stuart Jackson says: “Calls to our hotline are highlighting opportunities for these products in spring 2012. The products are ideal in wheat drilled late after potatoes or sugar beet. Both products offer robust blackgrass control and after sugar beet will provide effective control of weed beet as well as a wide range of other grass and broad-leaved weeds."

“When targeting first and second wheats drilled earlier in the autumn it is important to treat as soon as active growth is detected. The smaller the weed, the more effective control will be.”

All the pyroxsulam-based products offer both contact and residual modes of action. Thus Mr Jackson urges growers not to delay treatment.

“Early control will be important this spring as autumn weather conditions meant autumn-applied residual treatments have run out of steam earlier than normal,” says Mr Jackson.

With the additional bonus of no following crop restrictions growers have complete flexibility on future cropping plans without the need for specific cultivations.
