New Herbicide for Fodder Beet

New Herbicide for Fodder Beet

Wednesday, March 10, 2010

A herbicide designed to help fodder beet growers simplify the often-complex process of weed control is being launched for 2010 by United Phosphorous.

Triology is for post-emergence use soon after weeds germinate and works by targeting weeds with three different active ingredients, says the company's UK sales manager Richard Allen. "It also treats weeds with a robust overall dose of active ingredient, yet its specially-developed formulation shows a high degree of safety to the crop.

"Fodder beet is a traditional crop which has swung back into favour," explains Mr Allen. "Weeds are a major cause of yield loss, but present a dilemma for control.

"Fodder beet is highly susceptible to weed competition during its critical establishment phase, but weeds germinate in multiple flushes and are often much faster-growing. Also, fodder beet can be very sensitive to herbicides, yet the weeds which compete with it are not easy to control with gentle sprays.

"For these reasons, a programme of several low dose herbicide sprays at the start of the season is frequently used. In launching Trilogy as a post-emergence treatment we have tried to make this process simpler - by providing a product which already combines three different active ingredients, designed to give a higher level of weed control, cover a broader range of weeds, and ultimately give improved yield."

The three active ingredients contained in Trilogy - contact-acting phenmedipham and desmedipham, and residual ethofumesate - which remains active in the soil for several weeks. Each covers a different weed spectrum. This may not eliminate the need to mix herbicides with it completely, but should certainly help reduce the amount of total mixing, adds Mr Allen.

"The weed spectrum of Trilogy includes annual meadow grass, black bindweed, chickweed, fat hen, forget-me-not, field pansy, field pennycress, ivy-leaved speedwell, knotgrass, shepherds purse, small nettle, sun spurge, red dead nettle, charlock, cleavers, orache, mayweeds, pale persicaria and redshank."
