Warnings
 
  • Handle concentrate with care.
  • Harmful if swallowed.
  • May be irritating to eyes.
  • Store in cool place away from food, feed, seed or other agricultural remedies.
  • Keep out of reach of children, uninformed persons and animals.
  • Use of Basta in any other way or time as indicated in the “Directions for use” may lead to plant injury or other negative effects.
  • Re-entry – Do not enter treated area within one day after treatment unless wearing protective clothing.
  • In case of poisoning – CALL A DOCTOR AND MAKE THIS LABEL AVAILABLE TO HIM.
  • Although Basta has been tested on most important cultivars and no significant phytotoxicity in the form of yield reduction has been recorded under normal growing conditions, this does not mean that a more sensitive cultivar might not be commercialised in the future. Where a new cultivar is encountered, large areas should not be sprayed without prior testing of Basta on that cultivar.
  • ALTHOUGH THIS REMEDY HAS BEEN EXTENSIVELY TESTED UNDER A LARGE VARIETY OF CONDITIONS, THE REGISTRATION HOLDER DOES NOT WARRANT THAT IT WILL BE EFFICACIOUS UNDER ALL CONDITIONS BECAUSE THE ACTION AND EFFECT THEREOF MAY BE AFFECTED BY FACTORS SUCH AS ABNORMAL SOIL, CLIMATIC AND STORAGE CONDITIONS, QUALITY OF DILUTION WATER, COMPATIBILITY WITH OTHER SUBSTANCES NOT INDICATED ON THE LABEL AND THE OCCURRENCE OF RESISTANCE OF THE WEEDS TO THE REMEDY CONCERNED AS WELL AS BY THE METHOD, TIME AND ACCURACY OF APPLICATION. THE REGISTRATION HOLDER FURTHERMORE DOES NOT ACCEPT RESPONSIBILITY FOR DAMAGE TO CROPS, VEGETATION, THE ENVIRONMENT OR HARM TO MAN OR ANIMAL OR FOR LACK OF PERFORMANCE OF THE REMEDY CONCERNED DUE TO FAILURE OF THE USER TO FOLLOW THE LABEL INSTRUCTIONS OR TO THE OCCURRENCE OF CONDITIONS WHICH COULD NOT HAVE BEEN FORESEEN IN TERMS OF THE REGISTRATION. CONSULT THE SUPPLIER IN THE EVENT OF ANY UNCERTANTY.

First Aid
 
  • Inhalation:
    If symptoms persist, call a physician. Move to fresh air. Keep patient warm and at rest.

  • Skin contact:
    Take off contaminated clothing and shoes immediately and wash off with soap and plenty of water. If symptoms persist, call a physician.

  • Eye contact:
    Wash off immediately with plenty of water for at least 15 minutes. Remove contact lenses, if present, after the first 5 minutes, then continue rinsing eye. Get medical attention if irritation develops and persists.

  • Ingestion:
    Do NOT induce vomiting. Keep at rest. Rinse mouth. Call a physician or poison control centre immediately.

Note To Physician
 
  • Appropriate supportive and symptomatic treatment as indicated by the patient's condition is recommended.
  • 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.
  • Forced alkaline diuresis and haemodialysis may be considered.
  • There is no specific antidote.
  • 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.
  • Oxygen or artificial respiration if needed.
  • Keep respiratory tract clear.
  • ECG - monitoring (Electrocardiogram).
  • EEG - monitoring (Electroencephalogram).
  • Monitor: respiratory, cardiac and central nervous system.
  • Keep under medical supervision for at least 48 hours.

Symptoms
 
  • Vomiting, Diarrhoea, Abdominal pain, Tremors, Hypotension, muscular weakness, Unconsciousness, Coma, Convulsions, respiratory failure, Nausea, Tachycardia.
    Symptoms may be delayed.

Resistance Management
 
  • For resistance management, Basta is a Group Code H herbicide. Any weed population may contain individuals naturally resistant to Basta and other Group Code H herbicides. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds may not be controlled by Basta or any other Group Code H herbicides.
  • Since the presence of resistant weeds is difficult to detect prior to herbicide application, it is of the utmost importance that treated areas be inspected at regular intervals to identify the occurrence of herbicide-resistant weeds timeously. Bayer (Pty) Ltd will not accept liability for performance failures in the event of a build-up of resistant weeds resulting from inadequate resistance management practices as indicated on the label.
  • To delay herbicide resistance:
    • Avoid exclusive repeated use of herbicides from the same herbicide Group Code. Alternate or tank mix with products from different herbicide Group Codes.
    • Integrate other control methods [chemical, cultural, biological] into weed control programmes.
  • For specific information on resistance management contact your local Bayer CropScience representative.

Precautions
 
  • Do not inhale vapours or spray mist and avoid skin contact.
  • Wear protective clothing (boots, face shield, rubber gloves) when handling or applying the product. Wash contaminated clothing daily.
  • Do not eat, drink or smoke whilst mixing or applying or before washing hands and face and changing clothes.
  • Wash with soap and cold water after use or skin contact.
  • Prevent spray drift onto other crops, grazing, rivers, dams or other areas not under treatment.
  • Prevent contamination of food, eating utensils, feed and drinking water.
  • Clean all equipment thoroughly after use and do not pollute the environment with wash water.
  • 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 burying or burning it. Do not use the container for any other purpose.

Directions of Use
 
  • USE ONLY AS DIRECTED
  • METHOD OF APPLICATION:
  • Ground application:
    • Use 300 - 500 l water/ha depending on size of weeds
    • For weeds in the seedling stage (up to 10 cm high) use the lower listed dose. For weeds taller than 10 cm but less than 50 cm use the higher listed dose. For weeds 50 cm and taller increase the volume of water to 800 l /ha without increasing the dose above that of the highest listed one.
    • Addition of soil acting herbicides for more persistent weed control
    • Goal EC, or Bayer Diuron depending on the crop, can be added at the registered rate to one of the subsequent sprays after the first Basta treatment has been made to reduce the volume of the early crop of weeds ensuring better penetration through to the soil surface. If the early crop of weeds does not form a dense stand the two chemicals can be sprayed in combination at the time of the first spray.
  • Spot spraying
    • Where spot spraying is conducted the same recommendations should be followed as for overall spraying and the same concentration of mixture used (15 - 25 ml/l water). Weeds should be thoroughly wetted with this spray mixture.
    • Basta can only be sprayed on common reed where the areas of growth are drained, or where the water systems wherein they grow are closed or confined areas with standing water (dams, pans or vlei). Where contact between Basta and adjoining water has been made - DO NOT USE THIS WATER FOR DOMESTIC PURPOSES FOR A MINIMUM PERIOD OF 24 HOURS AFTER APPLICATION.
  • IMPORTANT NOTES:
    1. Seedlings that have not emerged at the time of application will not be controlled or are not damaged. No action via the roots is present.
    2. Damage symptoms in the form of yellowing and leaf scorch to the aerial portions of plants commence 7 - 10 days after treatment and maximum control is achieved 2 - 6 weeks after spraying depending on weed spectrum and environmental conditions.
    3. Optimum herbicidal action following leaf uptake is obtained under environmental conditions favourable for active plant growth as well as for young growing plants having a large proportion of foliage with a high metabolic rate.
    4. The use of Basta sprays at the prescribed doses will remove weed competition within orchards etc., for a period of usually not less than 6 weeks in the case of an established weed population, but often greatly in excess of this period, depending upon the weed species, type of weed, stage of development, whether the weeds are annual or perennial as well as upon environmental factors.
    5. Irrigation prior to application of Basta assists in weed control. DO NOT SPRAY WEEDS UNDER ENVIRONMENTAL STRESS such as drought, low temperatures, waterlogging and salinity as herbicidal action may be affected. This also applies to weeds which are senescing or dormant, or growing slowly due to other plant stress inducing factors.
    6. TWELVE HOURS should be left between spray application and the re-commencement of irrigation where perennials and waxy leafed weeds have been sprayed.
    7. In the case of weeds which do not have waxy leaves or in the case of small annual weeds EIGHT HOURS should be left between spray application and re-commencement of irrigation.
    8. What has bearing upon irrigation also has bearing upon the effect of rainfall above 5 mm.
    9. No impairment of plant growth takes place if crops are planted in soil recently treated with Basta as breakdown is rapid.
    10. Do not spray when weeds are wet from rain or irrigation
    11. Do not spray if weeds are covered with a heavy layer of mud, dust or debris as may occur when flood irrigation is in use.
    12. Green side shoots and suckers may be sprayed and scorched without damage extending to the rest of a fruit tree or vine.
    13. Ensure that direct spray or drift is kept out of contact with green leaves, active buds and fruit.
    14. In the case of young trees with green stems, these should be protected or spray shields used to prevent damage to non-suberised bark.
    15. It is recommended that low hanging branches should be trimmed to avoid leaf and fruit contact as well as to prevent interference with weed control.
    16. Bananas should be at least 2 years old before spray is allowed to come into contact with the plants.
    17. Only the bases of the pseudostems should be permitted to come in contact with the spray.


 
Mixings Instructions
 
  • Shake container well before use.
  • USE CLEAR CLEAN WATER FOR MIXING AND AVOID WATER WHICH IS CONTAMINATED BY MUD, MINERALS OR ORGANIC MATTER.

Compatibility
 
  • Compatibility studies have been conducted with Basta in combination with MCPA (Reg. No. L 1404) and may therefore safely be mixed together.

  • Bayer (Pty) Ltd. does not accept responsibility for tank mixtures with any other products or with MCPA formulations other than mentioned above.

  • Do not combine Basta in the spray tank with other chemicals, unless your prior use has shown the combination to be physically compatible and non-injurious.

  • The compatibility of Basta with other products may be influenced by the formulation of the other products involved as well as the quality of the water. Since the formulation of other products may change without the knowledge of Bayer (Pty) Ltd. and the quality of water may vary from farm to farm, a physical compatibility test should always be carried out prior to application.
