Stinger herbicide is a new broad spectrum woody weed, pasture, winter cereal and fallow herbicide.

Woody Weeds: the label covers extensive list of weeds and a range of application techniques including high volume, boom spray, aerial (helicopter only), low volume high concentrate (gas gun) and use in tolerant grass pastures/pasture renovation. Stinger is an economical first strike for graziers and land managers with extensive infestations of blackberry.

Winter cereals and fallow: Stinger also offers broadacre growers in the  northern grain region a residual tank mix product for use in winter cereals and fallow sprays.


Cost-effective option for foliar spraying of large infestations of tough-to-kill woody weeds and many noxious or environmental weeds.

Acts on both weed foliage and roots to provide rapid reduction in total weed biomass

Stinger is specifically designed to be used for biomass reduction as the first step (year 1) in a three-cycle, three-year pasture improvement program. Follow-up eradication treatments in year 2 and year 3 can then be effectively undertaken.

Leaf brownout and distortion of stem tips will normally be obvious within a week of application.
