Etho SC Herbicide is a selective soil‐applied herbicide for use in sugar beets for the control of the weed species listed below. It provides effective control of these weeds for up to 10 weeks following application.
Lady’s thumb, Purslane, Shephard’s‐purse, Kochia, Barnyard Grass, Wild Oats, Volunteer Wheat, Common Lamb’s‐quarters, Redroot Pigweed, Pennsylvania Smartweed, Crabgrass, Foxtail, Volunteer Barley and Volunteer Oats.
Etho SC Herbicide will also reduce competition of these hard‐to‐control weed: Wild Buckwheat, Russian Thistle, and Black Nightshade.
DIRECTIONS FOR USE:
Read the entire Directions for Use before using this product.
SHAKE CONTAINER WELL BEFORE USING.
DO NOT apply this product directly to freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs, ditches and wetlands), estuaries or marine habitats. DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) medium classification.
The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, rangelands, riparian areas and shrublands) and sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs, ditches and wetlands).
When a tank mixture is used, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture.
SOIL PREPARATION: The soil should be prepared according to good agricultural practices. Large clods can reduce the effectiveness of Etho SC Herbicide. All existing vegetative growth should be thoroughly worked into the soil before treatment.
SPRAY EQUIPMENT: Apply Etho SC Herbicide to the soil using standard low pressure (150 ‐275 kPa) ground spray equipment. Spray equipment should be carefully calibrated before use and checked frequently during application to see that it is functioning properly.
Apply uniformly the recommended rate in 110‐560 litres of water per hectare.
Avoid overlaps since crop injury may result. Do not use smaller than 50‐mesh strainer and never less than an 8002E nozzle orifice. A Tee Jet 8003E is a better choice for this purpose and is recommended for appropriate screen to orifice size relationship.
MIXING DIRECTIONS: When mixing Etho SC Herbicide in the spray tank with Pyramin, add Etho SC Herbicide first and agitate spray solution thoroughly.
GROUND APPLICATION, DO NOT APPLY BY AIR1
FALL LAYERING APPLICATION: This method of application can be used when spring moisture is marginal, or where irrigation water is not available at planting time. Fall bedding utilizes the winter‐accumulated moisture to enhance activation of the herbicide and to aid in germination of the Sugar beet crop.
Prepare the field (as for planting: plow, pack and float, etc.) in the fall before ground freezes. Apply Etho SC Herbicide in a band on the soil surface at the recommended rate indicated in the appropriate regional dose table. Be sure that the soil surface to be treated is free from trash and vegetation.
Cover the treated bands with soil and form beds or ridges using ditchers or discs. In the spring when the soil is sufficiently dry to be worked, deridge the beds down to within 1.0 to 2.5 cm of the treated layer using suitable equipment such as the Kirchner Bedder or Oregon Northslope Harrow. When deridging, maintain the original bedding guidance system by using a bull tongue chisel, slide guides or similar equipment. This will ensure that the planter will follow in the treated band.
Plant Sugar beets in the deridged area when the soil conditions allow.
SPRING APPLICATION: Apply Etho SC Herbicide before or at planting time and incorporate into the soil to a depth of 2.5 to 5.0 cm. Deeper incorporation may reduce effectiveness.
INCORPORATION EQUIPMENT: Test results have shown hooded‐power or grounddriven rotary tillers, rolling cultivators and harrows to be effective for incorporating Etho SC Herbicide into the soil. Do not apply Etho SC Herbicide through soil injector shanks.
CULTURAL PRACTICES FOLLOWING APPLICATION: When properly applied Etho SC Herbicide will provide up to 10 weeks’ control of susceptible weed species. Inrow cultivation and thinning practices will reduce the period of weed control; therefore, care should be exercised to minimize soil disturbance.
For resistance management, Etho SC Herbicide is a Group 16 herbicide. Any weed population may contain or develop plants naturally resistant to Etho SC Herbicide and other Group 16 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistancemanagement strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of Etho SC Herbicide or other Group 16 herbicides with different herbicide groups that control the same weeds in a field.
Use tank mixtures with herbicides from a different group when such use is permitted.
Herbicide use should be based on an IPM program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices.
Monitor treated weed populations for resistance development.
Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance‐management and/or integrated weedmanagement recommendations for specific crops and weed biotypes.
