Abstract/Contents:"Recent research results have shown that two new herbicide products have a fit in the crop grouping 'grasses grown for seed' in Western Oregon. In field studies conducted in perennial ryegrass and tall fescue seed crops, halauxifen/florasulam (Quelex) and bicyclopyrone/bromoxynil (Talinor) have provided control of several important weed species with no apparent negative effects to the crop. A non-replicated test application on a roadside in 2014 indicated that halauxifen/florasulam had potential for wild carrot control. In a 2014-15 study initiated that fall along the edge of a commercial tall fescue planting, halauxifen/florasulam applied at 0.75 oz/A (product) controlled 93% of the wild carrot population present compared to 40% for tribenuron (Express) + 2,4-D/dicamba acid (Latigo). In a 2017 study conducted in a grass field road, wild carrot was controlled 87% with halauxifen/florasulam compared to 63 % with fluroxypyr/trichlopyr + 2,4-D/dicamba acid and 35 % control with tribenuron + 2,4- 61 D/dicamba acid. Two perennial ryegrass studies in 2015 and in 2016 resulted in no yield difference between an untreated check treatment and halauxifen/florasulam applied at 0.75 oz product/A. A perennial ryegrass study in 2016 also resulted in no differences in yield between an untreated check treatment and bicyclopyrone/bromoxynil applied at 13.7 oz product/A. Bicyclopyrone/bromoxynil controlled corn spurry, white clover, sticky chickweed, annual knawel, shepherd's purse and redmaids greater than 90% in the perennial ryegrass. A study conducted in 2017 in spring seeded tall fescue, bicyclopyrone/bromoxynil applied at 18.2 oz/A product + co-actA (buffer), provided 99% control of a mayweed chamomile which was comparable to pyrosulfotole/bromoxynil (Huskie) + 2,4-D/dicamba acid with 98%. Studies in spring seeded tall fescue had no growth reduction from applications of these products. In conclusion, both herbicide mixtures are safe to both perennial ryegrass and tall fescue and would be useful for weed management in grass seed crops."
