“…Flumetsulam, a sulfonanilide herbicide from DowElanco, has undergone evaluation on New Zealand pastures and arable crops since 1986 (Hare et al 1993). Current label claims cover use on new and established white clover and perennial ryegrass (Lolium perenne) pastures, lucerne (Medicago sativa) and clover seed crops and maize (Zea mays) to control a range of broadleaf weeds.…”

Flumetsulam was evaluated for control of giant buttercup (Ranunculus acris) in nine trials in established pastures. Repeat annual applications of flumetsulam (50 g/ha) in spring or autumn gave 82 and 89% control respectively, 12 months after the third application. Spring applications gave greater control than autumn applications in the first year. After two or three applications over successive years there was no difference in control between spring and autumn applications. Flumetsulam was well tolerated by established white clover (Trifolium repens). Treatments gave a marked improvement in pasture utilization by dairy cows.

“…When 23 oz. of 2,4-DB was applied to seedling chicory in the winter on poorly drained silty alluvium soil in New Zealand, Grasslands Puna chicory did not recover as well and spring DM yields were less than UTC (160 and 400 lb/acre, respectively) (Hare et al, 1993).…”

“…Gawn et al (2012) reported relatively little damage to 'Puna II' chicory by flumetsulam applied at two rates 5 weeks after planting in Palmerston North, New Zealand. However, Hare et al (1993) reported an average of 74% injury to Grasslands Puna chicory seedlings 2 to 3 months after autumn application of 34 oz. 2,4-DB/acre in New Zealand on a poorly drained, silty alluvium soil (Kairanga silt loam).…”

“…Similarly, when 34 oz. 2,4-DB/acre was applied to mature Grasslands Puna chicory in New Zealand on a poorly drained, silty alluvium soil (Kairanga silt loam), Hare et al (1993) reported 3 and 47% visual injury 30 and 120 DAT, respectively. Flumioxazin + 2,4-DB treatment exhibited less injury over time, which was the only treatment containing 2,4-DB exhibiting this pattern.…”

Chicory (Cichorium intybus L.) is a short‐lived perennial warm‐season forb in the Asteraceae family. Although its use is predominantly as a wildlife food plot component in the Unites States, it is widely used in countries such as New Zealand as alternative forage for livestock. There is potential for utilizing chicory in mixtures with perennial pasture species such as tall fescue {Festuca arundinacea Schreb. [syn. Schedonorus arundinaceus (Schreb.) Dumort]} and alfalfa (Medicago sativa L.). The objectives of these field experiments were to determine the effects of various herbicides on the percent injury and forage yield of (i) established chicory treated in the spring and (ii) newly‐planted chicory treated in autumn. Pendimethalin, imazethapyr, and flumetsulam alone or with 0.5% methylated seed oil (MSO) were safe to apply regardless of season. Bromoxynil and flumioxazin alone or with 2,4‐DB were most injurious to chicory regardless of season. In all instances, chicory sufficiently recovered from injury and there were no differences in forage yield among herbicide treatments compared to the untreated controls. Even though chicory injury responses to herbicides were no longer apparent at forage harvest, it is recommended that herbicides that are least injurious to chicory that also provide greatest weed control be used to reduce the risk of chicory stand failure.

A field trial was conducted in Palmerston North to assess weed control options for establishing mixed swards of chicory (Cichorium intybus) narrowleaved plantain (Plantago lanceolata) red clover (Trifolium pratense) and white clover (Trifolium repens) a pasture mixture currently popular for finishing lambs Haloxyfop safely controlled grass weeds and mowing twice during the first few months of establishment helped control some broadleaved weeds Flumetsulam was the safest herbicide for controlling broadleaved weeds although it caused severe suppression of plantain initially All other treatments caused unacceptable levels of damage to at least one of the sown species If chicory was not included in the mix then bentazone paraquat/diquat and diuron could be used Options for an integrated weed control programme for the mixture of four species are discussed For young cloverbased pastures hemlock (Conium maculatum) will be controlled better by flumetsulam or bentazone than 24DB
