ENVIRONMENTAL HAZARDS
This chemical is toxic to fish and aquatic invertebrates.
Do not apply directly to water, to areas where surface water is present or to intertidal areas below the mean
high water mark. Runoff may be hazardous to aquatic organisms in neighboring areas. Cover or incorporate
granules that are spilled during loading or are visible on soil surface in turn areas.
Alachlor can contaminate surface water through spray drift. Under some conditions, alachlor may also have
a high potential for runoff into surface water (primarily via dissolution in runoff water), for several weeks post­
application. These Include poorly draining or wet soils with readily visible slopes toward adjacent surface
waters, frequently flooded areas, areas over-laying extremely shallow ground water, areas with in-field
canals or ditches that drain to surface water, areas not separated from adjacent surface waters with
vegetated filter strips, and areas over-laying tile drainage systems that drain to surface water. Do not apply
to water or areas where surface water is present, or to intertidal areas below the mean high water mark.
This chemical and/or its soil degradates are known to leach through soil into ground water under certain
conditions as a result of registered uses. Use of this chemical in areas where soils are permeable,
particularly where the water table is shallow, may result in ground-water contamination.
Do not apply to highly permeable soils, (as classified by the USDA Natural Resources Conservation Service)
where the depth to ground water is 30 feet or less.
Do not contaminate water when disposing of equipment washwaters or rinsate.

GENERAL INFORMATION
This product is recommended for control of yellow nuts edge and the annual grasses and broad leaf weeds
listed in the "WEEDS CONTROLLED" section of this label. This product may be applied either as a surface
application prior to or after planting or shallowly incorporated prior to planting to blend the herbicide
treatment into the upper 1/2 to 2 inches of soil. Except for minimum or conservation tillage systems, the
seedbed should be fine, firm and free of clods and trash.
Performance is improved when mOisture occurs within one week after application. The amount required
depends primarily upon the amount of soil moisture in the weed germination zone at the time of application,
soil type and organic matter content, but 1/3 to 3/4 inch is generally sufficient for performance of this
product. High intensity or excessive rainfall or excessive irrigation after application may reduce control. This
product will not control emerged seedlings.
Use of this product not consistent with this label may result in injury to persons, animals or crops or other
unintended consequences. Keep container closed to prevent spills and contamination.
USE PRECAUTIONS AND RESTRICTIONS
This product may not be mixed or loaded within 50 feet of perennial or intermittent streams and rivers,
natural or impounded lakes and reservoirs. This product may not be mixed/loaded or used within 50 feet of
all wells, including abandoned wells (unless the well has been properly capped or plugged), drainage wells,
and sink holes. Operations that involve mixing, loading rinsing, or washing of this product into or from
pesticide handling or application equipment or containers within 50 feet of any well are prohibited unless
conducted on an impervious pad constructed to withstand the weight of the heaviest load that may be
positioned on or moved across the pad. Such a pad shall be designed and maintained to contain any
product spills or equipment leaks, container or equipment rinse or wash-water, and rain water that may fall
on the pad. Surface water shall not be allowed to either flow over or from the pad, which means the pad
must be self-contained. The pad shall be sloped to facilitate material removal. An unroofed pad shall be of
sufficient capacity to contain, at a minimum, 110% of the capacity of the largest pesticide container or
application equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclude
preCipitation form contact with the pad shall have a minimum containment capacity of 100% of the largest
pesticide container or application equipment on the pad. Containment capacities as described above shall
be maintained at all times. The above-specified minimum containment capacities do not apply to vehicles
when delivering pesticide shipments to the mixing/loading site.
Users are advised to not apply this product to highly permeable soils (es classified by the USDA Natural
Resources Conservation Service) where the water table (ground water) is close to the surface and where
these soils are well drained.
SOIL TEXTURE
Applicators should evaluate soil and weed conditions carefully to assure that they choose the lowest
effective label rate.
The recommended use rates of this product generally vary with soil texture. Unless soil texture is specifically

It is important that the applicator be calibrated properly to deliver the desired amount of this product. To
calibrate, set the applicator and attach a bag over the spreader plate or remove the delivery tube and attach
a plastic nursing bottle over the spout. Operate at a constant speed on terrain to be planted. Four to 5 mph
is suggested. For a 14-inch band, collect the granules for 500 linear feet (583 sq. ft. area) and measure the
VOLUME or WEIGHT collected. Tap plastic nursing bottle or other measuring container gently to settle the
granules when taking a reading.
Refer to the following table to determine the broadcast rate per acre for the amount collected. If necessary
adjust the application equipment so that each spout dispenses the proper amount.

APPLICATION TIMING AND METHODS
Preemergence Surface Application - This product may be applied to the soil surface after planting and
prior to either crop or weed emergence. Apply within 5 days of last preplant tillage. If weeds emerge after
treatment, or if treatment is applied more than 5 days after last preplant tillage, rotary hoe or shallowly
Lasso II 1994-1 Revised 4/19/96

1\//'1
cultivate immediately to im prove performance. Precipitation or overhead sprinkler irrigation is required after
application to move the herbicide treatment into the weed germination zone. The amount of precipitation or
overhead sprinkler irrigation required depends on existing soil moisture, soil type and percent organic matter
content, but 1/3 to 3/4 inch is normally adequate. Performance is improved when moisture is received within
7 days after application and prior to weed emergence. High intensity or excessive rainfall or excessive
irrigation after application may reduce control.
CULTIVATION INFORMATION
If grass or weed seedlings emerge before it rains, rotary hoeing will improve performance.
If cultivation is necessary because of soil crusting or compaction, tillage should be shallow to minimize
dilution of this herbicide.
Except for the above, as long as the grasses and weeds are controlled, delay cultivation as long as possible.
Only after weeds emerge in the treated band, set cultivator to throw soil into the row covering the band. On
peanuts, do not throw soil into the row.
WEEDS CONTROLLED
Applicators should evaluate soil and weed conditions carefully to assure that they choose the lowest
effective label rate.
When applied as directed under the conditions descrioed, this product CONTROLS the following weeds:

for the soil to be treated.
Use the higher rate in the recommended range in areas of heavy weed infestation. Use a minimum of
17 pounds per acre on coarse soils and 20 to 26 pounds on medium and fine soils to control black or
hairy nightshade.
*** When applied under sprinkler irrigation on coarse soils, use a minimum of 20 pounds per acre of this
product.
For Lister or Deep Furrow Planted Corn
Broadcast Treatment-Apply at the rate of 16 pounds per acre.
Band Treatment (Behind Press Wheel)--For a 10 inch band treatment over the row (40 inch spacing) apply
4 pounds per acre. For a 7 inch band treatment over the row (40 inch spacing), apply 2.8 pounds per acre.
If heavy rains follow application, weed control on the top and sides of the furrow may not be as good as that
obtained in the bottom of the furrow.
Where deep lister planting is practiced, only partial weed control can be expected on steep furrow sides. It is
suggested that a 7 inch band be applied at the bottom of the furrow. Better results can be expected where
the granules lie on an even flat surface which is not subject to shifting by wind or rain.
For Furrow Irrigated Corn
This product must be incorporated into the soil by harrow, finger weeder or rotary hoe. Shallow incorporation
of at least 112 inch but not more than 2 inches may result in unsatisfactory weed control. Incorporation
deeper than 2 inches may result in unsatisfactory weed control. Incorporation depth must be kept above the
seed. Soil moisture at application must be sufficient for crop and weed emergence. Irrigation within 10 days
following planting may improve weed control. See the table above for recommended rates.
SOYBEANS
When making applications on soybeans, do not exceed a total of 20 pounds of this product per acre per
year.
