New fungicide active cleared for crop leaf diseases

Cereal, corn, soy and pulse growers have a new active fungicide ingredient to throw at "key" leaf diseases in those crops.
The crop protection wing of DuPont Canada has picked up federal approval for registration of Acapela, whose new active ingredient, picoxystrobin, comes from the Group 11 (strobilurin) class of fungicides.
The product's approval from Health Canada's Pest Management Regulatory Agency covers its use against "an impressive list of foliar diseases" and for suppression of white mould in soybeans.
The new product has "unique movement properties that differentiate it from other fungicides," Dave Kloppenburg, the company's fungicide launch manager, said in a release last week. "It moves across the waxy layer of the leaf surface and systemically within leaf tissues."
In cereal crops, DuPont said, Acapela is meant to protect the two to three upper leaves of the plant -- including the flag leaf, whose health is "critical" for reaching higher yields -- against plant ailments such as leaf rust, powdery mildew, septoria leaf blotch and tan spot.
In pulses such as lentils and field peas, Acapela is to be billed as a "powerful new tool for control of major diseases such as mycosphaerella blight."
A product label for Acapela wasn't immediately available this week, but the company said in a research update last year that it would submit Acapela for registration for use also on canola -- a crop not mentioned in last Thursday's release.
The research update said DuPont would file for Acapela's use at a formulation of 250 grams per litre.
