Betanal Forte

Betanal Forte has offered forty years of effective weed control for New Zealand farmers. Betanal Forte is an effective post-emergence contact herbicide for the control of a wide variety of broad leaved weeds in beet crops.

Betanal Forte readily controls seedling stages of: chickweed, fathen, fumitory, groundsel, redroot, shepherd’s purse, spurrey, nettle and twin cress. Black nightshade, cornbind and willow weed are controlled only up to four true leaf stage.  Grass weeds, mature annual broad-leaved weeds, perennial broadleaved weeds and wireweed are not controlled. 

Small beet plants do not tolerate competition from weeds. You should aim, therefore, to establish  the crop quickly in a fine, firm seedbed and ensure weed competition is eliminated by applying a robust weed control programme.

Effective weed control during the first 8 - 10 weeks of the crop's life will maximise crop yields and returns.

  • Betanal has a proud 40 year history of effective weed control and ongoing product innovation around the world.

Using Betanal Forte on Fodder Beet

Weeds: Please refer to the label for a full list of the weeds controlled. 

Use 1.5 L/ha in 200 - 300 L of water after the crop has two leaves fully developed.

Using Betanal Forte on Sugar and Red Beets

Weeds: Please refer to the label for a full list of the weeds controlled.

Use 3.0 L in 200 L of water/ha after the crop has two true leaves fully developed.

For best results treat weeds at the youngest possible stage. Damage may occur especially on red beet if treated prior to the two true leaf stage.  For weeds up to four true leaves, use 3.0 L/ha in 200 L of water. Best results are obtained when weeds are treated at the youngest possible stage.  For weeds from 4 - 6 true leaves and hard to kill weeds up to four true leaves, use 4.5 L/ha in 200 L of water. Note: Do not apply if air temperatures are likely to exceed 29oC on the day of spraying. Herbicide activity will also be slowed down in cool weather.
