Treated grass weeds show a reduction in vigor and growth. Early chlorosis/necrosis of younger plant tissue is followed by a progressive collapse of the remaining foliage. Symptoms will generally be observed in 7 to 14 days after application, depending on grass species treated and environmental conditions.
Timing of Applications
Apply Intensity One Post-Emergence Grass Herbicide postemergence to actively growing grasses according to rate table recommendations. Applications made to grass plants stressed by insufficient moisture, hot or cold temperatures, or to grass plants exceeding recommended growth stages may result in unsatisfactory control. Do not apply under these conditions.
In arid regions where irrigation is used to supplement limited rainfall, Intensity One Post-Emergence Grass Herbicide should be applied as soon as possible, after an irrigation (within 7 days). In arid regions, a second application of Intensity One Post-Emergence Grass Herbicide will generally provide more effective control of perennial grass weeds than a single application. Make a second application to actively growing grass 2 to 3 weeks after emergence of new growth.
Cultivation of treated grasses 7 days prior to or within 7 days after application of Intensity One Post-Emergence Grass Herbicide may reduce weed control.
Use of sufficient spray volumes and pressure is essential to ensure complete coverage. Use a minimum of 5 gals. and a maximum of 40 gals. of spray solution per acre. Under the following conditions a minimum of 10 gals. per acre is required: ultra narrow row cotton, narrow row soybeans, broadleaf herbicide tank mixes, perennial grasses, volunteer corn, drought or stress conditions, heavy grass pressure or when grasses are at or near maximum height. Failure to use a minimum of 10 gals. per acre under these conditions can result in poor coverage and the reduced grass control requiring repeat applications. Spray pressures should reflect a minimum of 30 psi and a maximum of 60 psi at the nozzle. Do not use flood nozzles.
Applications to onions (dry bulb and green), garlic or shallots (dry bulbs and green) should be made in a minimum of 20 gals. of spray solution per acre.
Use a minimum of 3 gals. of spray solution per acre unless otherwise directed in the label. Increase spray volumes up to 10 gals. as grass or crop foliage becomes dense. For onions (dry bulbs and green), garlic or shallots (dry bulbs and green): When applying by air do not exceed 17 fl. oz./A in a single application. In California, air applications to onions, garlic, or shallots should be made in a minimum of 20 gals. of spray solution per acre. In states other than California, air application to onions, garlic or shallots should be made in a minimum of 10 gals. of spray solution.
NOTE: Crop injury may occur when Intensity One Post-Emergence Grass Herbicide is applied to onions, garlic or shallots with aerial equipment.
When using hand sprayers or high volume sprayers utilizing hand guns, mix 1/3 to 2/3% (0.44 to 0.85 oz. per gal.) Intensity One Post-Emergence Grass Herbicide and treat to wet vegetation, while not allowing runoff of spray solution. For uses requiring crop oil concentrate, include crop oil concentrate at 1% (1.3 oz. per gal.) by volume. For uses requiring non-ionic surfactant, include non-ionic surfactant at ¼% (0.33 oz. per gal.) by volume.
NOTE: If Intensity One Post-Emergence Grass Herbicide is applied as a spot treatment care should be taken to not exceed the maximum rate allowed on a \"per acre\" basis or crop injury may occur.
RESTRICTIONS AND LIMITATIONS
- Do not apply if rain is expected within 1 hour of application, as control may be unsatisfactory.
- Do not plant rotational crops until 30 days after application of Intensity One Post-Emergence Grass Herbicide unless crop is listed on Intensity One Post-Emergence Grass Herbicide label.
- Do not apply a postemergence broadleaf herbicide within one day following application of Intensity One Post-Emergence Grass Herbicide or reduced grass control may result.
- Intensity One Post-Emergence Grass Herbicide is not recommended for use on vegetable crops being grown for seed production unless specific use directions are provided.
- Do not apply under conditions of stress. Applying Intensity One Post-Emergence Grass Herbicide under conditions that do not promote active grass growth will reduce herbicide effectiveness. These conditions include drought, excessive water, extremes in temperature, low humidity and grasses either partially controlled or stunted from prior pesticide applications. Grasses under these kinds of stressful conditions will not absorb and translocate Intensity One Post-Emergence Grass Herbicide effectively, and will be less susceptible to herbicide activity.
APPLICATION ON LONG ISLAND, NEW YORK IS RESTRICTED TO NO MORE THAN 32 FL. OZ. OF INTENSITY ONE POST-EMERGENCE GRASS HERBICIDE (0.25 LB/A.I.) PER ACRE, PER SEASON.
Optimal perennial grass control can be obtained if rhizomes or stolons are cut up by preplant tillage practices (discing, plowing, etc.) to stimulate maximum emergence of grass shoots. Cultural practices, such as continuous no-tillage in which the perennial grass rhizomes or stolons are not cut up, results in a very staggered, non-uniform weed emergence. Due to this non-uniform weed emergence, no fewer than two Intensity One Post-Emergence Grass Herbicide applications per season per year are recommended at the appropriate weed growth stage rate under continuous no-till conditions.
Grass crops such as corn, rice, sorghum, small grains or turf etc. are highly sensitive to Intensity One Post-Emergence Grass Herbicide.
While all the vegetable crops on the label have been tested and are tolerant to Intensity One Post-Emergence Grass Herbicide not all specialty varieties of these crops have been tested. It is advised that, before applying Intensity One Post Emergence Grass Herbicide to specialty varieties of vegetable crops on the label, crop tolerance be investigated first using a small section of the field. It is possible that injury symptoms can occur. Symptoms may appear as leaf speckling or stunting.
Always read and follow the restriction and limitations for all products whether used alone or in a tank mix. The most restrictive labeling of any product used applies in tank mixtures, including all crop rotational and other crop restrictions.
Tank mixes of Intensity One Post-Emergence Grass Herbicide and broadleaf herbicides may result in reduced grass control. If grass regrowth occurs, an additional application of Intensity One Post-Emergence Grass Herbicide may be necessary.
Intensity One Post-Emergence Grass Herbicide is a Group 1 herbicide. Any weed population may contain or develop plants naturally resistant to Intensity One Post-Emergence Grass Herbicide and other Group 1 herbicides. Weed species with acquired resistance to Group 1 may eventually dominate the weed population if Group 1 herbicides are used repeatedly in the same field or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by Intensity One Post-Emergence Grass Herbicide or other Group 1 herbicides. Repeated use of Intensity One Post-Emergence Grass Herbicide (or similar postemergence grass herbicide with the same mode of action) may lead to the selection of naturally occurring biotypes that are resistant to these products in some grass species.
If poor performance occurs and cannot be attributed to adverse weather or application conditions, a resistant biotype may be present. This is most likely to occur in field where other control strategies such as crop rotations, mechanical removal and other classes of herbicides are not used from year to year.
To delay herbicide resistance consider:
- Avoiding Intensity One Post-Emergence Grass Herbicide or other target site of action Group 1 herbicides that have similar target site of action, on the same weed species.
- Using tank mixtures or premixes with herbicides from different target site of action groups as long as the involved products are all registered for the same use, have different sites of action, and are both effective at the tank mix or prepack rate on the weed(s) of concern.
- Basing herbicide use on a comprehensive IPM program.
- Monitoring treated weed populations for loss of field efficacy.
- Contacting your local extension specialist, certified crop advisors, and/or manufacturer for herbicide resistance management and/or integrated weed management recommendations for specific crops and resistant weed biotypes.
