Liquid Harvest Mesotrione is a highly effective herbicide that prevents the germination of crabgrass seeds and kills broadleaf weeds upon contact while allowing certain cool season turfgrass to grow weed . Waterhemp control failure in a soybean field. Tenacity inhibits a plant enzyme that is essential for photosynthesis and interferes with chlorophyll production. Label instructions suggest spraying only after newly germinated turfgrasses have been mowed twice, or 4 weeks after emergence. It is most effective in controlling summer annual grasses when mixed with a methylated seed oil or crop oil concentrate. The seed germination period of summer annual grasses ranges from spring to midsummer, and vegetative growth occurs throughout the summer. Populations with less than 40% survival at 3x the labeled rate but 40% or more survival at the labeled rate (1x) were classified as moderately resistant. Tenacity is most effective in controlling summer annual grasses when mixed with a nonionic surfactant. Susceptible weeds turn white before they die, creating a highly visible treatment effect following application.

No other product has the weed control spectrum of Mesotrione, which suppresses many of the most troublesome pre and post-emergence grassy and broadleaf weeds, allowing new turf seedlings to thrive. Its active ingredient, mesotrione, is based on a naturally occurring compound produced by the bottlebrush plant (Callistemon citrinus) that inhibits photosynthesis in susceptible plant species. Diversify your weed management strategy Integrating cultural and mechanical control tactics with chemical control strategies will improve waterhemp management. ), other products such as Clarity/dicamba, 2,4-D, Permit, Peak, Huskie, Maestro, Facet L, Yukon, as well as a few other herbicides.

Please check with your local extension service to ensure registration status. Below are some basic considerations when using them. mesotrione: 27: 3 fl oz/A: In this study, waterhemp populations exhibiting 40% or more survival at 3x the labeled rate of a herbicide were classified as 'highly resistant' to that herbicide. . Login or Register for the Latest GreenCast Updates. Waterhemp populations resistant to these herbicide sites of action were previously reported in Minnesota, but our experiment demonstrated that resistant populations are spreading rapidly across the state. Whatever the reason, weed control is necessary to ensure good crop yield and herbicides provide an effective means. Suspected herbicide-resistant weeds may be identified by these indicators: Lawn and Turfgrass Weeds: Yellow Woodsorrel, Oxalis stricta L. Apple Cultivars - Newer Scab Resistant Selections. Rainfall soon after the herbicide application may cause run-off. Repeat applications may be necessary for complete control of summer annual grasses, but total seasonal applications should not exceed 16 fl oz/acre. Moreover, we observed new cases of herbicide resistance in waterhemp in Minnesota. Tenacity can be mixed with prodiamine, dicamba, triclopyr, fluroxypyr, or carfentrazone when used on established turf. For various reasons, sorghum is starting to catch on here in the state.

According to the product label Tenacity may cause temporary whitening of turfgrass foliage. Two populations from Lincoln and Lyon Counties exhibited resistance to Raptor (Group 2), Enlist One (Group 4), Dicamba (Group 4), Aatrex (Group 5), Roundup PowerMAX (Group 9), Flexstar (Group 14), and Callisto (Group 27). This product is packaged in a 40 lb. The target species, stage of growth of the weed grass, and corresponding herbicide rate are extremely important for successful control, so applicators must pay close attention to product label directions. A repeat application after two to three weeks may be required for adequate weed control. Mesotrione is based on a naturally-occurring compound that inhibits photosynthesisin susceptible plants.

From the top down, the Atticus Team is visible, accessible and standing by for your questions. Two waterhemp populations exhibited tolerance to Xtendimax (Group 4). CR scenarios were compared to a broadcast treatment of mesotrione at 280 g ai ha -1 applied twice at 3-wk intervals, and a nontreated. Feature Flags: { using preemergence herbicides at full rates at planting will keep the field relatively weed-free at the beginning and that will provide some extra time for postemergence weed control. This herbicide can also control several species of broadleaf weeds, as well as creeping bentgrass, nimblewill, and nutsedge in turf. . 87316 Lucto 1 Gallon DFU.indd 1 4/1/20 1:14 PM. Research showed that preemergence followed by postemergence herbicide program was superior for waterhemp control than a single-pass program. Torocity is most effective when applied to a clean application site and when weeds are at the early stage of development. These six-way resistant waterhemp populations (resistant to six herbicide sites of action) left only Liberty for postemergence control of waterhemp in corn and soybean. Contains 40% mesotrione, a naturally occurring byproduct of the bottle brush plant Used during turf establishment and renovation projects to prevent or eliminate weeds and reduce competition with emerging turfgrass 104206-82-8 KEEP OUT OF REACH OF CHILDREN.

In this study, waterhemp populations exhibiting 40% or more survival at 3x the labeled rate of a herbicide were classified as highly resistant to that herbicide. Pylex can control numerous broadleaf weed species, as well as nimblewill and dallisgrass in turf. Walking or driving through an area recently treated with a non-selective herbicide to an untreated area can cause damage to the untreated area. 3. Powered by mesotrione and an HPPD site of action, Callisto controls annual broadleaf weeds in field corn, seed corn, yellow popcorn, sweet corn and other labeled crops.
