What's new in 2022 - weed control in winter crops

To keep you up to date with what’s new from the  agri-chemical companies in 2022, NSW DPI has produced the following list. This includes both new products and new use patterns of already registered herbicides.

Overwatch® (400 g/L bixlozone) is a pre-emergent herbicide from FMC Australia, controlling a range of grass and broadleaf weeds in wheat, barley, and canola. It is now registered in faba bean and field peas. Overwatch® offers long-lasting residual ryegrass control (including resistant biotypes) and other weeds with its unique Group 13 mode of action.

Reflex® (240 g/L fomesafen) is a new Group 14 pre-emergent herbicide from Syngenta. Reflex® provides residual control of a wide range of broadleaf weeds in chickpea, faba bean, narrow-leaf lupin, field pea, lentil and vetch.

Complete Mateno® Complete (aclonifen 400 g/L, diflufenican 66 g/L, pyroxasulfone 100 g/L) from Bayer CropScience combines 3 active ingredients from 3 modes of action, including aclonifen, a new herbicide mode of action for Australia (Group 35) to control some grass and broadleaf species. In wheat, Mateno® Complete can be used in early post emergence. In wheat and barley, Mateno® Complete can be incorporated by sowing (IBS use pattern).

Ultro® 900 WG
Ultro® 900 WG (900 g/kg) carbetamide is a new and unique mode of action herbicide (Group 23) from Adama. It offers long residual, pre-emergent control of ryegrass, barley grass and brome grass in pulses (chickpea, faba bean, field pea, lentil, lupin and vetch).

Herbicide Encode® Herbicide (500 g/kg butroxydim) from Adama controls annual ryegrass, barley grass and wild oats in winter pulse crops (including chickpea, faba bean, field pea, lentil, lucerne, lupin and vetch). It can be tank-mixed with other grass herbicides to broaden its weed spectrum and improve the overall control of hard-to-kill annual grasses.

Herbicide Sentry® (525 g/kg imazapic and 175 g/kg imazapyr) is now registered IBS in imidazolinone-tolerant oats as a result of a partnership of 3 Australian companies: Nufarm, InterGrain and Grains Innovation Australia. This is for use on the first herbicide tolerant oat variety, KingbaleA, which will be commercialised by InterGrain this season.

Weedmaster® DST®
Weedmaster® DST® (470 g/L glyphosate), a Group 9 herbicide from Nufarm, is now registered for pre-harvest use in barley (other than malting) and over-the-top and pre-harvest use in TruFlex® Canola.

Intercept® herbicide
Intercept® (33 g/L imazamox and 15 g/L imazapyr) a Group 2 herbicide from Nufarm, now has an exclusive registration in imidazolinone-herbicide tolerant faba bean.

Saracen® (50 g/L florasulam) from Nufarm is the first straight florasulam (Group 2) product to be registered in Australia. Saracen is a flexible mixing partner for controlling a variety of broadleaf weeds in barley, wheat, oats, triticale and ryegrass pasture. Additional weeds controlled include charlock, hedge mustard, Mexican poppy, prickly lettuce, turnip weed, wild turnip and suppression of matricaria, with new, wider application timings registered.

Terrad'or® 700WG (700 g/kg tiafenacil) from Nufarm is the first product in Australia containing the new active ingredient tiafenacil, a Group 14 herbicide. It is used to control and increase the speed of brownout of a range of broadleaf and grass weeds before establishment of crops and fallows.
