Several new and expanded product labels approved by the PMRA

The Canadian Pest Management Regulatory Agency (PMRA) has recently registered minor use label expansions for several chemical products used on horticultural crops.

Zampro

Zampro fungicide (ametoctradin + dimethomorph), produced by BASF Canada Agricultural Solutions, is now registered for use against downy mildew on spinach (control) and blackberries (suppression).

Zampro was previously registered for downy mildew and a variety of blights in grapes, hops, potatoes, as well as Brassica, cucurbit, leafy and fruiting vegetables. This label expansion was requested by Agriculture and Agri-Food Canada’s Pest Management Centre due to reports from growers and extension personnel.

Altacor

Altacor (chlorantraniliprole) is a Group 28 insecticide produced by FMC. It is now registered for use against peach tree borer and lesser peach tree borer in all stone fruit.

Altacor was previously registered for use against other insect pests, including several fruitworm species, Japanese beetles, and other boring insects, in apples, grapes, pears, tree nuts, stone fruit and a variety of berries.

Serifel

BASF’s Serifel (Bacillus amyloliquefaciens strain MBI600) is a Group 44 biofungicide with multiple modes of action, which is also compatible with organic production.

New for the 2021 growing season, Serifel is now available for use on a range of fruiting, leafy, root and cucurbit vegetables, and berries. Serifel was previously registered for use in targeting powdery mildew and botrytis in grapes.

Diplomat

Belchim Crop Protection Canada’s Diplomat biofungicide (polyoxin D zinc salt) was recently expanded for control of:

• powdery mildew on caneberries (including blackberries and raspberries);
• leather rot, and phomopsis leaf spot and fruit rot on strawberries; and
• downy mildew and phomopsis fruit rot on grapes.

Diplomat is a biofungicide that controls diseases for a variety of fruit, vegetable and ornamental crops. It is the only Group 19 fungicide registered for food use in Canada.

Lalstop G64 WG

Lalstop G64 WG biofungicide (Gliocladium catenulatum strain J1446), produced by Lallemand Plant Care, was recently registered for suppression of damping-off, crown and root rot, Botrytis stem canker and grey mould on greenhouse-grown eggplant, Asian water spinach, strawberries and indoor-grown cannabis in Canada. 

Previously known as Prestop WG, Lalstop G64 WG was already labelled for use on several greenhouse-grown vegetables, herbs and ornamentals in Canada for management of these diseases and others.

Miravis Prime and Duo

Initially registered in grapes and leafy greens, Syngenta’s Miravis Prime fungicide is now also on label for strawberries and highbush blueberries.

Miravis Prime combines Adepidyn and fludioxonil (Group 12) for resistance management and control of key diseases, such as Botrytis fruit rot and grey mould.

Previously registered in several vegetable crops, Miravis Duo (also produced by Syngenta) is now available for use on potatoes against early blight, brown spot, Botrytis and white mould. Miravis Duo contains Adepidyn and difenoconazole (Group 3) as its active ingredients, and is the only non-chlorothalonil fungicide on the potato market offering activity against Botrytis.
