CRABGRASS CONTROL - PROGRAM 1 WEST

General Information

GENERAL INFORMATION

This product is NOT recommended for application by homeowners.

In the state of New York, this product may be applied by commercial applicators ONLY.

This product controls crabgrass, other annual grasses and broadleaf weeds in established lawns, ornamental turf (including golf course fairways, roughs and tee boxes), and landscape ornamentals.

This product will not control emerged weeds, except for control of crabgrass up to initiation of tillering because the tillering stage of crabgrass growth generally corresponds to the time when seedlings are first visible in established turfgrasses.

Applying to crabgrass after tillering starts will not provide satisfactory control, and all other applications of this product should be made prior to germination of target weeds.

To be effective, this product must be activated by at least 1/2 inch of rainfall or irrigation. Applications should be timed to ensure that activation occurs prior to the tillering stage of crabgrass development or prior to germination of all other weeds.

USE PRECAUTIONS

- Do NOT allow the pouches to become wet prior to adding them to the spray tank.

- Do NOT remove the water-soluble pouches from the protective over-wrap except to add them directly to the spray tank.

- Do NOT handle the pouches with wet hands or wet gloves.

- Always reseal over-wrap bag to protect remaining unused pouches.

Limitations, Restrictions, and Exceptions

For crabgrass control in the spring, summer, or fall, apply this product as a single application, a split application, or as a sequential application.

Spring / Early Summer Applications

Applied at the rate recommended by the appropriate control programs for your area and conditions. The total rate applied directly impacts the duration of residual weed control, but will also vary somewhat depending upon the weather, severity of weed pressure, turfgrass competitiveness, and the user’s location.

Use Program1: This program provides 3 to 5 months of preemergence control and early postemergence control of crabgrass up to the 3-leaf stage in siteswhen turfgrass is cut relatively high (such as homeowner lawns).

Use Program 2: This program provides 4 to 6 months of preemergence crabgrass control in sites where the turfgrass is cut relatively low (such as golf fairways) and turfgrass maintenance or weed control was conducted during the previous year. This program may also be used for early postemergence control up to crabgrass tillering in sites where turfgrass is cut relatively high (such as residential lawns).

Use Program 3: This program provides 4 to 6 months of preemergence crabgrass control in sites where turfgrass is cut relatively low (such as golf fairways) and turf maintenance or weed control was NOT conducted during the previous year. This program may also be used for early postemergence control up to crabgrass tillering at sites where turfgrass is cut relatively low (such as golf fairways). If longer periods of control are desired, follow the initial application with sequential pre- and/or postemergence applications. In some cases, improved weed control may result if the rates recommended in the table below are split across two applications 5 to 10 weeks apart.

Maximum Use Rates

- Do NOT apply more than 0.5 lb. ai per acre per application or more than 1.5 lb. ai per acre per year using split or sequential applications. This is equivalent to 4 water-soluble pouches per acre or 0.46 oz./1000 sq. ft. (1.25 lb./acre of product) per application and 12 water-soluble pouches per acre or 1.38 oz./ 1000 sq. ft. (3.75 lbs./acre of product) per year.

- In New York State, do not apply more than 0.25 lb. ai per year. This is equivalent to 2 water-soluble pouches (0.625 lb./acre) per acre or 0.23 oz./1000 sq. ft. of this product.

Fall Applications

To control crabgrass through the early part of the following spring, apply this product in late summer or early fall (late August through November) at the “Program 3” use rates listed in the table above. For season-long weed control, follow the fall application with an appropriately timed spring application being sure to not exceed maximum use rates listed above.

Note: Because this product will not control emerged broadleaf weeds or grasses (with the exception of crabgrass up to tillering stage of development), the area to be treated should be free of weeds prior to application.

Preemergence applications totaling more than 0.5 lb. ai/acre (greater than 1.25 lbs./acre of product) must be applied as a split application. The recommended interval for split applications is 5 to 10 weeks apart. Early postemergence applications are limited to 0.5 lb. ai/acre (1.25 lbs. of product) per application.

NOTE: For split application, the rate are as follows: 29040-21780 number of sq ft / pouch / treatment; 1.5-2 number of pouches / acre; 0.47-0.625 lbs of product / acre; 0.38+0.38 lbs of AI / acre

For this climatically diverse region, like Nevada, use the higher rates in local areas with longer crabgrass seasons The water-soluble bag is NOT designed to be re-measured or subdivided and should not be opened. Treat an appropriate number of acres to use a whole number of bags.
