“It (Heat herbicide) gives you much faster control than glyphosate alone and a broader spectrum so you would pick up (and control) your Roundup Ready canola.”
Manitoba flax growers can now use Headline fungicide to combat pasmo (Septoria linicola).
It’s just one of a number of new labels or products to come from BASF recently.
“The biggest problem with flax is the variability of yield,” Robert Hornford, BASF’s senior technical development representative for oilseeds and forages said during a recent BASF plot tour. “There are guys that get 16 (bushels an acre), there are guys that get 35. The biggest advantage with Headline in this crop is disease control.”
Last year Manitoba farmers harvested, on average, a record 25 bushels an acre of flax, exceeding the previous record of 23 set in 1996. But the average yield the past eight years has only been 19.4 bushels an acre, according to crop insurance data.
Based on 58 trials, BASF found spraying flax with Headline resulted in an average of 7.5 bushels an acre in yield, Hornford said.
To prevent pasmo, Headline should be applied eight to 10 days after first flower.
Headline’s registration in flax was a co-operative effort between BASF, the Manitoba Minor Use Co-ordinators, the Manitoba Flax Growers Association and Flax Council of Canada.
Pasmo is characterized by circular, brown lesions on the leaves and by brown to black infected bands that encircle the stem, says Manitoba Agriculture, Food and Rural Initiative’s website. These bands alternate with green, healthy bands, making pasmo easy to identify. Flowers and young bolls are also blighted. Older bolls are discoloured and contain shrivelled or non-viable seed.
MORE DISEASE CONTROL
Earlier last month Headline received an emergency-use registration to control rust in sunflowers. And next year the company expects its Caramba fungicide (metconazole) will be registered for disease control, including fusarium head blight, in cereals.
According to Hornford, Caramba will reduce the level of deoxynivalenol (DON), a toxin produced by fusarium, better than any other product.
Caramba also provides excellent leaf disease control, according to Hornford.
Another way to fight fusarium is through plant breeding. A new Clearfield herbicide-tolerant Canada Western Red Spring wheat (BW859) will be available in limited supply next year.
BW859 has a rare “Good” rating for resistance to fusarium – the same rating as 5602 HR and Waskada.
Viterra’s Xceed Clearfield canola has a split personality. The plant looks a lot like mustard, but its oil is canola quality. Indeed, Xceed canola is in the “juncea” or mustard family.
“What this plant brings is drought resistance and it can handle higher temperatures at flowering,” which is a characteristic of mustard Hornford said. “This is a much more tolerant plant in terms of environmental stresses. That helps reduce your risk. The other thing is this also has shatter resistance, so some guys want this for straight cutting (at harvest time).”
Manitoba and Alberta edible growers have a new herbicide option.
In June an emergency-use registration was granted for Solo tank mixed with Basagran Forte and UAN fertilizer to control a range of post-emergent grassy and broadleaf weeds.
A Group 6 contact herbicide, Basagran Fortecontrols broadleaf weeds including ragweed, lamb’s quarters, velvetleaf, Canada thistle and yellow nutsedge.
Solo, a Group 2 herbicide, controls a wide range of grassy and specific broadleaf weeds.
The tank mix is Solo mixed with a half-litre per acre of Basagran Forteand 810 millilitres of UAN fertilizer, Hornford said.
Viper is BASF’s new broad-spectrum herbicide for peas. Viper controls green smartweed, lamb’s quarters, wild mustard and volunteer canola, including Clearfield canola.
Viper suppresses cleavers, wild buckwheat and kochia, including Group 2-resistant types.
Green foxtail, barnyard grass and volunteer wheat, including Clearfield varieties, are among the grassy weeds Viper controls. It also suppresses Japanese brome grass.
Viper has two modes of action so it reduces the threat of weeds becoming herbicide resistant, while not restricting farmers from planting a wide variety of crops in treated fields the following year.
Tensile is a new BASF herbicide for use in Clearfield canola. It controls a wide range of broadleaf and grassy weeds, including wild buckwheat and green foxtail. It also suppresses Canada thistle and kochia with few rotation restrictions.
Heat is a new pre-seed/post-emergent herbicide BASF hopes will be registered for use next year. It’s used with the non-selective weed killer glyphosate.
“It gives you much faster control than glyphosate alone and a broader spectrum so you would pick up (and control) your Roundup Ready canola,” Hornford said.
The active ingredient in Heat is Kixor, a new Group 14, which kills weeds through contact and systemically.
Hornford said Heat will control weeds up to the eight-leaf stage, including wild buckwheat and volunteer canola, including Roundup Ready.
Heat can be applied on land being seeded to pulses, all cereals and chemfallow.
It’s safe to plant a wide range of crops including barley, wheat, canola, corn, edible beans, flax, oats, peas and soybeans the year following an application of Heat. [email protected]
