DIRECTIONS FOR USE
- Thor should not be applied to any crop suffering from stress as a result of drought, waterlogging, low temperatures, pest or disease attack, nutrient or lime deficiency or other factors reducing crop growth.
- Do not use THOR on cereals crops undersown with grasses, clover or other legumes or any other broad-leaved crop.
- Due to the high level of activity of the herbicide, special care must be taken to avoid damage by drift onto brad-leaved plants outside the target area, or onto ponds, waterways or ditches. Thorough cleansing of equipment is also very important – see below.
- Contract agents should be consulted before using on crops grown for seed.
- Thor should not be applied within 7 days of rolling the crop.
- Do not apply Thor more than once to any cereal crop.
- All requirements or restrictions on other product labels must be adhered to when applied to the same crop as Thor.
Thor contains tribenuron methyl, sulfonylurea herbicide, which works mainly by contact action and is most effective if applied when the weeds are small and actively growing. Good spray cover of the weeds must be obtained for the best results. Susceptible plants cease growth almost immediately after application and symptoms can be seen two weeks after application. Weed control may be reduced when soil conditions are very dry The susceptibility rating of weeds in the following table refer to good spray cover and good growing conditions.
When herbicides with the same mode of action are used repeatedly over several years in the same field, selection of resistant biotypes can take place. These can propagate and may become dominating. A weed species is considered resistant to herbicide if it survives a correctly applied treatment at the recommended dose. Development of resistance with a weed species can be avoided or delayed by alternating (or tank mixing) with suitable products having a different mode of action. For control of Corn Marigold or Chickweed this product must always be applied with an alternative mode of action product at recommended rates.
A strategy for preventing and managing resistance should be adopted. Further details and advice on how t implement such a strategy may be obtained from your crop advisory or chemical supplier The Herbicide Resistance Action Committee (HRAC) also produced guidelines which may be consulted for additional information.
Thor can be used post-emergence on all varieties of wheat, barley, oats, winter rye, durum wheat, triticale and set-aside areas at the growth stages given below.
Set Aside Areas
Thor can be used for broad-leaved weed control in set-aside land within current guidelines. Only cereals may be sown in the same calendar year t set-aside land treated with THOR.
Only cereals, oilseed rape, field beans or grass may be sown in the same calendar year as harvest of a cereal crop treated with THOR. In case of crop failure fr any reason, sow nly cereals within three months of application of Thor. Before swing, soil should be ploughed and cultivated to a depth of at least 15-cm.
Thor may be applied from the three-leaf stage (GS 13) up to and including the flag leaf fuly emerged stage of growth (GS 39)
Apply Thr at 30 grams/hectare
VOLUME AND APPLICATION
BEFORE USING THOR, SPRAYING EQUIPMENT MUST BE CLEAN AND FREE FROM CONTAMINATION WITH OTHER PESTICIDES.
Application should be made in 100-200 litres of water per hectare using suitable ground equipment to give good spray cover of the weeds. When crops are thick or weed growth is dense, use 400 litres of water per hectare. Care should be taken not overlap spray swaths.
Quarter fill the spray tank with water, start the agitation and add the required quantity of THOR directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.
In any tank-mix add Thor to the tank first and ensure it is fully dispersed before adding the partner product. Do not allow Thor to come into contact with undiluted pesticide concentrate. Products should only be tank-mixed if each product can be applied with the label reommendations for its use. For further information contact your DuPont distributor.
SPRAY TANK CLEAN-OUT
POOR CLEANOUT PRACTICES AND INSUFFICIENT WATER VOLUMES USED FOR THE RINSE PROCEDURE MAY RESULT IN INADEQUATE REMOVAL OF PRODUT DEPOSITS. SUBSEQUENT USE OF APPLICATION EQUIPMENT IN THESE CIRCUMSTANCES MAY RESULT IN DAMAGE T NN CEREAS CROPS.
TO AVOID SUBSEQUENT DAMAGE TO CROPS OTHE THAN CEREALS, IMMEDIATELY AFTER SPRAYING THOR THOROUGHLY CLEAN ALL SPRAY EQUIPMENT, INCLUDING INSIDE AND OUTSIDE OF LID.
