PEANUTS - SUPPRESSION OF TROPICAL SPIDERWORT
Strongarm herbicide is a soil-applied product for control of broadleaf weeds in peanuts. Strongarm may be applied preplant incorporated, preplant surface, or preemergence through cracking in peanuts. \"Cracking\" of soil occurs when soil is displaced by germinating seedlings just prior to emergence.
General Use Precautions and Restrictions
- Read and carefully follow all applicable directions, precautions and restrictions on labeling for other products used in combination with Strongarm.
- Aerial application of this product is prohibited.
- Do not allow livestock to graze treated areas or harvest forage or hay from treated areas.
- Chemigation: Do not apply this product through any type of irrigation system.
- Do not use flood irrigation to apply or incorporate this product.
- This product must be used in a manner that will prevent back siphoning in wells, spills or improper disposal of excess pesticide, spray mixtures or rinsates.
- In peanuts, do not apply more than 0.45 oz of Strongarm per acre per year in any combination of preplant incorporated, preplant surface, preemergence through cracking applications.
- Do not apply Strongarm to peanuts in the states of New Mexico, Oklahoma and Texas.
- Iron Chlorosis: There are isolated areas of the country where soil induced iron chlorosis routinely occurs. Severity of iron chlorosis symptoms may increase when Strongarm is soil-applied in areas with a history of soil-induced iron chlorosis or other nutrient induced crop injury.
Handling Precautions for Water Soluble Packets: Do not remove water soluble packet from the overpack except for immediate use. Do not allow water soluble packets to come into contact with water prior to use. Do not handle water soluble packets with wet hands or wet gloves. Do not open water soluble packets (product in transparent film). Partial use of packets is not allowed. Carefully reseal package containing unopened water soluble packets and protect package from moisture.
Strongarm Applied Alone
Water dispersible granules of Strongarm are packaged in water soluble packets. Thorough mixing prior to and during application is required.
Application with Dry Bulk Fertilizer (Soil Application Only)
Dry bulk fertilizer may be impregnated or coated with Strongarm. Soil applications of dry bulk fertilizer impregnated with Strongarm provides weed control equal to the same rates of Strongarm applied in liquid carriers. Follow label recommendations for Strongarm regarding rates per acre, special instructions, precautions and limitations for soil application.
Apply 300 to 700 lb per acre of fertilizer/herbicide mixture. Apply the mixture uniformly to the soil with properly calibrated equipment immediately after blending. Uniform application of the herbicide/fertilizer mixture is essential for satisfactory weed control and to prevent possible crop injury. Non-uniform application may also result in unsatisfactory weed control. In areas where conventional tillage is practiced, a shallow soil incorporation of the mixture may improve weed control.
Most absorbent dry fertilizers can be used for impregnation with Strongarm. Pure ammonium nitrate and/or limestone will not absorb the herbicide and are not suitable for impregnation with Strongarm.
Absorbent fertilizer blends containing a mixture of ammonium nitrate and/or limestone as part of the fertilizer mixture may be impregnated.
Compliance with all federal and state regulations relating to blending pesticide mixtures with dry bulk fertilizer, registration, labeling and application are the responsibility of the individual and/or company offering the fertilizer and chemical mixture for sale.
Impregnation: Strongarm must be pre-mixed with water to form a slurry prior to impregnation of dry bulk fertilizer. For best results, use a minimum of 6 fl oz of water for each individual 0.45 oz water soluble packet of product. Pre-mixing can be accomplished by shaking the water soluble packets and water together in a closed container. A small amount of a silicon-based defoaming agent may also be needed. Make sure Strongarm is completely and uniformly dispersed in water and the water soluble packaging has completely dissolved. Add sufficient water to adjust the total volume of the mixture to deliver a spray volume of 0.5 to 1 gallons of fertilizer per ton. Nozzles used to spray Strongarm onto the fertilizer should be placed to provide uniform spray coverage. Use constant agitation to keep the spray mixture suspended.
Apply Strongarm in a broadcast spray when tropical spiderwort is in the 1 to 2 leaf stage of growth and actively growing. Applications made to larger weeds or to weeds under stress may result in unsatisfactory control. Optimum weed control will be obtained by applying Strongarm under favorable growing conditions (i.e., adequate soil moisture and temperature). Applications may occur from peanut cracking, to the initiation of flowering (bud stage), but no later than 30 days after planting.
