DRY PEAS - COARSE SOIL TEXTURE - EXCEPT GROUNDCHERRY AND NIGHTSHADE
Sonalan HFP herbicide is a preemergence herbicide that controls many annual grasses and broadleaf weeds in in crambe, dry beans, dry peas, gold of pleasure, peanuts, rapeseed, safflower, soybeans, and sunflower. Sonalan HFP controls weeds as they germinate. Sonalan HFP will not control established weeds.
USE PRECAUTIONS AND RESTRICTIONS
Poor weed control and/or crop injury may result if directions are not followed. Uneven application, over application, or improper incorporation can result in erratic weed control or injury to the treated or rotational crops.
Do not graze or forage crop grown in treated soil or cut for hay or silage. Do not apply Sonalan HFP to soils which are wet, cloddy, or subject to prolonged periods of flooding because poor weed control or crop injury may result.
Do not apply to any area not specified on the label.
Sonalan HFP will not control DNA (dinitroaniline) resistant goosegrass.
Chemigation: Apply Sonalan HFP through properly equipped chemigation systems to dry beans (does not include soybean) and sunflower. Follow use directions for these crops under the crop specific use directions of this label. Do not apply this product through any type of irrigation system to other labeled crops, unless otherwise specified by a Gowan Company product bulletin or supplemental label.
ROTATIONAL CROP RESTRICTIONS
If replanting is required, replant only crops listed on this label.
Sugar Beets or Red Beets
Do not plant sugar beets or red beets within 13 months following an application of 3 pints of Sonalan HFP or more per acre. Where less than 3 pints of Sonalan HFP per acre have been applied, sugar beets or red beets may be planted no earlier than 8 months after an application and then only if the soil treated with Sonalan HFP is moldboard plowed to a depth of at least 12 inches prior to planting.
Spinach or Oats
In California and Arizona, do not plant spinach or oats within 8 months following an application of 3 pints of Sonalan HFP or more per acre.
Small-Seeded Grasses (Bluegrass, Ryegrass, etc.)
Do not plant small-seeded grasses in the fall following a spring application of Sonalan HFP. Perennial grass crops or grass mixtures should not be planted for 12 months after application of Sonalan HFP to avoid the possibility of crop injury. If land has not been irrigated, these crops should not be planted for 18 months after a spring application of Sonalan HFP. Moldboard plowing to a depth of 12 inches before planting these crops will reduce the possibility of crop injury.
Special Rotational Crop Restrictions for the States of Montana and Wyoming
Plant only rapeseed (canola), safflower or sunflower as rotational crops in the crop year following the crop treated with 3 pints of Sonalan HFP per acre. In addition to rapeseed (canola), safflower or sunflower, spring seeded barley grown under irrigated conditions can be planted in the crop year following the crop treated with a 2 pint of Sonalan HFP rate per acre. If one of these specified crops is not planted, the land should be left idle or fallow for the entire year following the crop treated with Sonalan HFP.
Apply Sonalan HFP in at least 5 gallons of water or liquid fertilizer per acre (broadcast basis). Use any properly calibrated, low pressure herbicide sprayer that will apply the spray uniformly.
Application with Liquid Fertilizer
Sonalan HFP may be mixed with most liquid fertilizer materials. Combinations of Sonalan HFP with solutions and suspension type fertilizers provide weed and grass control equal to the same rates of Sonalan HFP applied in water. For application in liquid fertilizer, follow label directions regarding crops, application rates, incorporation directions and precautions for Sonalan HFP alone.
Compliance with individual state regulations relating to liquid fertilizer mixing, registration, labeling and application are the responsibility of the individual and/or company offering the fertilizer and chemical mixture for sale.
Application with Dry Bulk Fertilizer
Dry bulk fertilizer may be impregnated or coated with Sonalan HFP. Application of dry bulk fertilizer impregnated with Sonalan HFP provides weed and grass control equal to the same rates of Sonalan HFP applied in liquid carriers. Follow label directions regarding crops, application rates, and precautions for Sonalan HFP alone. Spread the fertilizer/chemical mixture with properly calibrated application equipment. Be certain the material is applied uniformly to the soil surface. When impregnated on dry bulk fertilizer, Sonalan HFP must be incorporated two times (see Soil Incorporation Directions).
Limitations: Apply a minimum of 200 lb of dry fertilizer impregnated with Sonalan HFP per acre at the recommended rate. Most dry fertilizers can be used for impregnation with Sonalan HFP. When coated ammonium nitrate and/or limestone are used alone, do not impregnate with Sonalan HFP. These materials will not absorb the herbicide. Blends containing a mixture of these materials can be impregnated.
Impregnation: Use any closed drum, belt, ribbon or other commonly used dry bulk fertilizer blender. Nozzles used to spray the Sonalan HFP onto the fertilizer should be placed to provide uniform spray coverage. Add water to the Sonalan HFP to give a total volume of at least 6 pints per ton of fertilizer.
Compliance with individual state regulations relating to dry bulk fertilizer blending, registration, labeling and application are the responsibility of the individual and/or company offering the fertilizer and chemical mixture for sale.
Sonalan HFP herbicide may be applied through properly equipped chemigation systems for weed control in dry beans (does not include soybeans) and sunflowers. Refer to instructions below for use directions for chemigation. Do not apply Sonalan HFP through any type of irrigation system unless these directions are carefully followed.
Application Timing: Planting and application should occur as soon as possible after the last tillage operation. Sonalan HFP must be applied within 2 days after planting prior to crop emergence. Sonalan HFP does not control established weeds. Soil incorporation is not required when Sonalan HFP is applied through chemigation systems.
Broadcast Application Rates for Chemigation Application: Use application rates specified for Sonalan HFP - Alone in the Dry Beans and Sunflowers sections of the product label. Apply Sonalan HFP in overhead sprinkler irrigation equal to 1/2 to 1 inch of water and use the maximum specified application rate for the soil texture class and weed species to be controlled.
Cultivation: Soil treated by chemigation with Sonalan HFP may be shallow cultivated without reducing weed control activity.
Sonalan HFP, applied in cool, wet conditions, has the potential to cause crop injury as seeds germinate. For best results, apply when weather is warm.
Factors influencing the uniform application and incorporation of Sonalan HFP:
Crop Residues or Existing Weeds - Excessive amounts of crop residues or existing weeds may interfere with the incorporation of Sonalan HFP into the soil. A manageable level of such ground cover will allow Sonalan HFP to be uniformly mixed into the top 2 to 3 inches of the final seedbed. If the level of the ground cover is such that this cannot be done, the soil must be tilled prior to the application of Sonalan HFP.
Soil Roughness - The soil surface should be smooth enough so that you can operate a sprayer and incorporation equipment without wheel slippage and at speeds sufficient to ensure uniform application and incorporation of Sonalan HFP.
General Soil Conditions - To assure uniform incorporation of Sonalan HFP, soil moisture conditions should be such that large clods can be broken up during the incorporation process.
Apply and incorporate Sonalan HFP any time after January 1 when soil can be worked and is in a condition which allows thorough mixing to insure uniform incorporation.
When applied with dry bulk fertilizer, Sonalan HFP may be applied and incorporated in the fall prior to a spring planting of dry beans or sunflowers. Apply Sonalan HFP with dry bulk fertilizer anytime between October 1 and December 31 at the specified rates for crops and soil textures listed in the Crop-Specific Use Directions section of this label. Fall application of Sonalan HFP is not recommended on fields which remain wet or are subject to periods of flooding.
SOIL INCORPORATION DIRECTIONS
Use incorporation equipment that thoroughly and uniformly mixes Sonalan HFP herbicide into the top 2 to 3 inches of the final seedbed or erratic weed control and/or crop injury may result. Incorporation should occur as soon as possible after application and, to prevent loss of herbicidal activity, should not be delayed more than 48 hours after application.
Incorporation in Bedded Culture
Application prior to bedding: Apply Sonalan HFP and mix thoroughly into the top 2 to 3 inches of soil. The bedding operation provides additional mixing. Do not expose untreated soil during post-bedding operations.
Application after bedding: Knock off beds to planting height before applying Sonalan HFP. Apply Sonalan HFP and mix thoroughly with equipment that will conform to the bed shape. Do not expose untreated soil during the incorporation process.*
*Avoid removal of treated soil from the seedbed before or during the planting operation. Exposure of untreated soil during planting will allow weeds to germinate in the drill row.
Incorporation When Applied with Dry Bulk Fertilizer
When impregnated on dry bulk fertilizer, Sonalan HFP must be incorporated two times. The first incorporation should occur as soon as possible after application, but not delayed more than 48 hours after application. For best weed control results, the second incorporation should be delayed at least 5 days after the first and occur before planting. When fall applied, the second incorporation may occur in the spring as a part of tillage associated with seedbed preparation. The second incorporation should be made in a different direction, and to avoid bringing untreated soil to the surface, should not be deeper than the first.
Optional Methods of Incorporation for Soybeans, Dry Beans and Peanuts on Medium and Coarse Textured Soils
Sonalan HFP may be applied as a surface application and incorporated by rainfall or sprinkler irrigation. Soil should be in good tilth and free of clods. Make applications to tilled land and/or standing or chopped stubble from the previous season’s crop. Conditions should permit thorough movement into the top 2 to 3 inches of the final seedbed. Application should be made immediately after tillage and after planting, but prior to rainfall or irrigation. Rainfall or sprinkler irrigation prior to application will tend to consolidate and seal the soil surface and prevent the downward movement of Sonalan HFP that is expected under porous, open, recently tilled conditions.
If continuous rainfall in the amount of at least 1/2 to 1 inch occurs within 2 days after application of Sonalan HFP, no further incorporation is required. If the prescribed amount of rainfall is not anticipated, supplemental overhead sprinkler irrigation of at least 1/2 to 1 inch of water may be applied within 2 days after application. Supplemental irrigation can be applied through a center pivot, solid set or hand moved sprinkler system. Furrow irrigation is prohibited. Mechanical incorporation methods should be used to incorporate Sonalan HFP if the required amount of rainfall or supplemental irrigation does not occur within 2 days after application. If mechanical incorporation is used, adjust equipment so as to not disturb planted seed.
Note: For crops with application rates that exceed 3.7 pints per acre, do not apply more than 3.7 pints (1.4 lb ai) per acre, regardless of the application rate in the specific use directions, if incorporation is to be accomplished by supplemental overhead sprinkler irrigation. Do not apply more than 2 pints (0.75 lb ai) per acre, regardless of the application rate in the specific use directions, if incorporation is to be accomplished by rainfall only.
Cultivation after Planting
Soil treated with Sonalan HFP may be shallowly cultivated without reducing the weed control activity of Sonalan HFP. Do not cultivate deeper than the treated soil since weeds may germinate where untreated soil is brought to the surface.
SOIL TEXTURE GUIDE FOR APPLICATION RATES
Use rates of Sonalan HFP for specific crops are based on the Soil Texture Class (coarse, medium, or fine) of the soil to be treated and organic matter content. A fine textured soil (clay loam) requires a higher use rate than a coarse-textured soil (loamy sand). Field soil textures, grouped according to Soil Texture Class, are listed in the table below and should be used to determine if the soil to be treated is coarse, medium or fine. Do not exceed specified use rates for specific crops or target weed species.
*Silty clay loam and sandy clay loam soils are transitional soils and may be classified as either medium or fine textured soils. If silty clay loam or sandy clay loam soils are predominantly sand or silt, they are usually classified as medium textured soils. If they are predominantly clay, they are usually classified as fine textured soils.
Application Rate Ranges: Where a rate range is shown, use the lower rate for more coarse textured soils in the Field Soil Texture Group or soils with low organic matter content. Use the higher rate in the rate range for more fine textured soils in the Field Soil Texture Group and soils containing more than 5% organic matter. Where soil texture is variable within the same field, use the lower specified rate for Sonalan HFP. Sonalan HFP is not recommended for use on soils containing more than 10% organic matter.
(Not for Use in California)
General Weed Control Except Groundcherry and Nightshade: Apply and incorporate Sonalan HFP in the spring before planting or in the fall. Fall application may be made only with dry bulk fertilizer. See instructions for fall application of Sonalan HFP under the heading Application Timing in the Product Information section of this label. Follow soil preparation, application, and incorporation procedures in the Product Information section of this label.
Precaution: Do not exceed these rates of Sonalan HFP for weed control in dry peas or crop injury may occur. Not all varieties of peas have been tested for tolerance to Sonalan HFP. Consult your seed contractor before applying Sonalan HFP to determine the tolerance of a particular pea variety. Application of Sonalan HFP to non-tolerant pea varieties may result in crop injury and reduced yields.
Restriction: Do not graze or forage crop grown in treated soil or cut for hay or silage.
Grasses and Broadleaf Weeds Controlled
Sonalan HFP applied preplant soil incorporated will control listed weeds.
Oat, wild: Sonalan HFP will provide wild oat control except those germinating below the zone treated with Sonalan HFP.
Pigweed: Sonalan HFP will not control DNA (dinitroaniline) tolerant biotypes of this weed species.
