First Aid
 
  • General advice: Remove contaminated clothing immediately and dispose of safely.
  • Inhalation: Move the victim to fresh air and keep at rest. Call a physician or poison control centre immediately.
  • Skin contact: In case of skin contact, immediately wash with plenty of soap and water for at least 15 minutes. Warm water may increase the subjective severity of the irritation / paresthesia. This is not a sign of systemic poisoning. In case of skin irritation, application of oils or lotions containing vitamin E may be considered. If symptoms persist, call a physician.
  • Eye contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Remove contact lenses, if present, after the first 5 minutes, then continue rinsing eye. Warm water may increase the subjective severity of the irritation / tingling. This is not a sign of systemic poisoning. Apply soothing eye drops, if needed anaesthetic eye drops. Get medical attention if irritation develops and persists.
  • Ingestion: Keep at rest. Rinse mouth. Do NOT induce vomiting. Risk of product entering the lungs on vomiting after ingestion. Call a physician or poison control center immediately.

Note To Physician
 
  • Treatment:
  • Local treatment: Initial treatment: symptomatic.
  • Systemic treatment: Initial treatment: symptomatic.
  • Monitor: respiratory and cardiac functions. In case of ingestion gastric lavage should be considered in cases of significant ingestions only within the first 2 hours. However, the application of activated charcoal and sodium sulphate is always advisable. Keep respiratory tract clear. Oxygen or artificial respiration if needed. In case of convulsions, a benzodiazepine (e.g. diazepam) should be given according to standard regimens. If not effective, phenobarbital may be used. Contraindication: atropine. Contraindication: derivatives of adrenaline. There is no specific antidote. Recovery is spontaneous without sequelae.

Symptoms
 
  • Local: Skin and eye paraesthesia which may be severe (usually transient with resolution within 24 hours), skin, eye and mucous membrane irritation, cough, sneezing.
  • Systemic: discomfort in the chest, tachycardia, hypotension, nausea, abdominal pain, diarrhoea, vomiting, dizziness, blurred vision, headache, anorexia, sleepiness, coma, convulsions, tremors, prostration, airway hyperreaction, pulmonary oedema, palpitation, muscular fasciculation, apathy.
  • Risks: This product contains a pyrethroid. Pyrethroid poisoning should not be confused with carbamate or organophosphate poisoning.

Resistance Management
 
  • For resistance management, Decis Forte is a Group Code 3 insecticide. Any insect population may contain individuals naturally resistant to Decis Forte and other Group Code 3 insecticides. The resistant individuals can eventually dominate the insect population if these insecticides are used repeatedly. These resistant insects may not be controlled by Decis Forte or any other Group Code 3 insecticides.
  • Since the presence of resistant insects is difficult to detect prior to insecticide application, it is of the utmost importance that treated areas be inspected at regular intervals to identify the occurrence of insecticide-resistant insects timeously. Bayer (Pty) Ltd will not accept liability for performance failures in the event of a build-up of resistant insects resulting from inadequate resistance management practices as indicated on the label.
  • To delay insecticide resistance:
    • Avoid exclusive repeated use of insecticides from the same insecticide Group Code. Alternate or tank mix with products from different insecticide Group Codes.
    • Integrate other control methods [chemical, cultural, biological] into insect control programmes.
  • Codling moth resistance management:
    • When used to control Codling moth (Cydia pomonella) in pome fruit, a maximum of four Decis Forte sprays must be applied to a single Codling moth generation.
    • To prevent or delay the development of resistance, products with other modes of action should be applied for the control of the other two generations. If Decis Forte is used for the control of the last generation of the season a product with another mode of action should be used for the control of the first generation in the next season.
  • American bollworm resistance management:
    • Resistance of American bollworm (Helicoverpa armigera) to synthetic pyrethroids has been confirmed.
    • COTTON: Synthetic pyrethroids may ONLY be applied to cotton during the period 1 January to 28 February.
    • DO NOT apply more than two pyrethroid applications per growing season. If more sprays are necessary, use a product with a different mode of action.
  • GENERAL: If a synthetic pyrethroid gives poor performance, DO NOT respray with any synthetic pyrethroid, even at a corrective dosage rate. Use a product with a different mode of action (from a different Group Code).
  • For specific information on resistance management contact your local Bayer CropScience representative.

Precautions
 
  • Do not inhale fumes or spray mist.
  • Wear protective clothing (overall, face shield, rubber gloves and boots) when handling or applying the product. Wash contaminated clothing daily.
  • Wash with soap and cold water immediately after accidental skin contact. In case of eye contact rinse immediately with running water for at least 15 minutes.
  • Do not eat, drink or smoke whilst mixing or applying or before washing hands and face and changing clothes.
  • Prevent contamination of food, eating utensils, feed and drinking water.
  • Prevent spray drift onto other edible crops, grazing, rivers, dams or other areas not under treatment.
  • Clean all equipment thoroughly after use and do not pollute the environment with wash water.
  • Do not calibrate aircraft or clear hopper over grazing, crops not under treatment or water sources.
  • When empty, invert the container over the spray tank or mixing tank and allow it to drain for at least 30 seconds after the flow has slowed down to a drip. Thereafter rinse the container three times with a volume of water equal to at least one tenth of that of the container and add the rinsing to the contents of the spray tank. Destroy the container by puncturing and flattening.
  • Do not use the container for any other purpose.

Directions of Use
 
  • USE ONLY AS DIRECTED
  • WATER QUALITY:
    • Water pH
      • Water with a very high / low pH can negatively influence the efficacy of Decis Forte.
      • Ideally the water pH should be between pH 5 and 8.
      • When spray water is above or below these criteria, it must be corrected with a suitable buffering agent.
  • Application through irrigation systems:
    • In the case of application through an irrigation system, the water used must be as clean as possible, i.e., free of silt, clay and organic material, which are particularly abundant in river water when in flood. Synthetic pyrethroids tend to adhere to these particles, reducing their efficacy.
    • Rainfastness properties:
    • Decis Forte has excellent rainfastness properties, however, if leaves are wet, do not spray.
  • METHOD OF APPLICATION:
    • Ground application:
      • Whether using mistblower or boom and nozzle sprayers, the same dosage rates/ha are applicable. Sprayers must be correctly calibrated to deliver the required volume of spray mixture evenly over the target area. The amount of water needed for good coverage may differ from apparatus to apparatus. The amount of spray mixture used/ha would depend upon the amount required to give adequate coverage with the particular apparatus. Use sufficient water to ensure thorough coverage.
      • Application in maize for Chilo or maize stalk borer control:
        • Apply using solid cone nozzles (D4/35 or D5/35), mounted two above each row with one nozzle angled down and the second slightly ahead, so as to spray directly into all the funnels and onto adjoining leaves. Use a pressure of not more than 3 bars (40 psi).
      • Application by centre pivot and sprinkler irrigation – maize only:
        • The system must contain a functional check valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow.
        • The pesticide injection pipeline must contain a functional, automatic, quick closing check valve to prevent the flow of fluid back toward the injection pump.
        • The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down.
        • The system must contain functional interlocking controls to shut off the pesticide injection pump automatically when the water pump motor stops.
        • The irrigation line or water pump must include a functional pressure switch, which will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected.
        • Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock.
        • Do not apply when wind conditions favour drift beyond the area intended for treatment.
        • The chemical injection tank should be cleaned before application to remove all fertilizer, pesticide and other foreign matter. The Decis Forte / water mixture in the injection tank should be under constant agitation. The irrigation system should provide uniform water flow and should have no leaks. Ensure that no surface pooling of water occurs.

Aerial Applications
 
  • DO NOT COMMENCE AERIAL APPLICATION BEFORE CONSULTING YOUR DECIS FORTE REPRESENTATIVE.
  • Aerial application may only be done by a registered aerial application operator using a correctly calibrated, registered aircraft according to the instructions of STANSA Code 0118 (Aerial Application of Agricultural Pesticides). It is important to ensure that the spray mixture is distributed evenly over the target area and that the loss of spray material during application is restricted to a minimum. It is therefore essential that the following criteria are met:
    • Equipment:
      • Use suitable atomising equipment (hydraulic nozzles or rotary atomisers) that will produce the desired droplet size and coverage, but which will ensure the minimum loss of product through drift.
      • The operator must use a setup that will produce a droplet spectrum with the lowest possible relative span.
      • All nozzles / atomisers should be positioned within the inner 75 % of the wingspan to prevent droplets from entering the wingtip vortices.
    • Application parameters:
      • A minimum volume of 30 l spray mixture per hectare is recommended. As this product has not been evaluated at a reduced volume rate, the registration holder cannot guarantee efficacy, or be held responsible for any adverse effects if this product is applied aerially at a lower volume rate than recommended above.
      • A droplet coverage of 30-40 droplets per cm² must be recovered at the target.
      • A droplet spectrum with a VMD of 250-280 microns is recommended. Ensure that the production of fine droplets (smaller than 150 microns) is restricted to a minimum.
      • The height of the spray boom should be maintained at 3-4 metres above the target. Do not spray when aircraft is in a climb, at the top or during a dive, or when banking.
      • Apply before the crop becomes too dense, thus preventing proper coverage of the plants.
    • Meteorological conditions:
      • The difference between the wet and dry bulb readings as determined by a whirling hygrometer, must not exceed 8 °C.
      • Do not spray under turbulent, unstable conditions during the heat of the day when rising thermals and downdraughts occur.
      • Do not spray under temperature inversion conditions (spraying in or above the inversion layer).
      • Do not spray if the wind speed exceeds 15 km/h.
    • General:
      • Ensure that fields are accurately marked and that the aerial spray operator knows exactly which fields to spray.
      • Obtain an assurance from the aerial spray operator that the above requirements will be met.


 

 

 
    Decis Forte is compatible with Lebaycid 500 EC (Reg. No. L1270), Mesurol 80 WP (Reg. No. L1896), Solubor, Ultracide (Reg. No. L2630) in apples and pears and Antracol 70 WP (Reg. No. L2065) on tomatoes. When applied for cutworm control, Decis Forte is compatible with emulsifiable concentrate and suspension concentrate formulations of herbicides belonging to the chloroacetamide and triazine groups. Flocculation sometimes occurs when mixtures are made with herbicides formulated as wettable powders. As formulations of pesticides change, Bayer (Pty) Ltd cannot take the responsibility for continuous testing of Decis Forte in the spray tank with other chemicals. Do not mix Decis Forte with other chemicals unless prior use has shown the combination physically compatible and non-injurious under conditions of use.

Use Restriction
 
  • WATER QUALITY:
    • Water pH
      • Water with a very high / low pH can negatively influence the efficacy of Decis Forte.
      • Ideally the water pH should be between pH 5 and 8.
      • When spray water is above or below these criteria, it must be corrected with a suitable buffering agent.
