DIRECTIONS FOR USE
Important: This information is approved as part of the Product Label. All instructions within this section should be read carefully in order to obtain safe and successful use of this product.
Soil and weather conditions
Moist soils are necessary for root uptake of JUDO. Best residual action is obtained in moist soils of fine tilth. JUDO may be applied under frosty conditions but it is important to avoid run-off from the soil surface. Avoid drift onto neighbouring crops. Avoid applying JUDO near water. Do not apply JUDO if heavy rain is forecast. Best results will be obtained when growth of weeds is slow but transpiration continues. In mild autumns/winters, emerged weeds may take longer to be controlled; the residual activity of JUDO will be shortened and overall control may be reduced. The efficacy of JUDO may be reduced in organic soils. Do not treat soils with more than 10% organic matter. Do not treat soils containing excessive organic debris.
Do not apply JUDO to the same land less than 9 months after previous application.
Take care to avoid local over-dosing.
Processed crops – No taints have been detected in tests with treated field crops. Consult your processor before use.
JUDO is a benzamide herbicide (HRAC Group K1). It is advisable to alternate the use of JUDO with a herbicide that has a different mode of action, thus minimizing the build-up of resistant strains. Weed control may be reduced if strains of weeds less sensitive to JUDO develop. Strains of some annual grasses (e.g. black-grass, wild-oats and Italian rye-grass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer
Crop, Application Rates and Timings
WINTER OILSEED RAPE
As a general rule, weed control and yield benefit will be optimal when treatment is made at an early growth stage.
Rate of application:
1.25-2.1 litres/ha (also see Control of Blackgrass in Winter Oilseed Rape)
Volume of water:
Apply JUDO in 200-500 litres of water per ha. Ensure good ground cover.
Rates of Application and Weeds Controlled:
Oilseed rape must be treated as soon as possible after 3rd true leaf stage. Crop selectivity depends on rooting depth and transient crop effects may occur to shallow-rooted crops. The application time is from 1st October to 31st January.
Control of Black-grass in Winter Oilseed Rape
Where populations of black-grass and/or volunteer cereals exceed 50/m2 JUDO should be applied in tank mix with an approved graminicide, or following an effective approved graminicide to ensure optimum weed control. Where partial resistance (R# or RR#) to the partner graminicide is known to exist the dose of JUDO may be increased to 2.1 litres/ha. This may also be done if applications are made early in the season, under warm conditions and an increase in the duration of residual control is required (see ‘Soil and weather conditions’ above). Where high levels of resistance (RRR#) to the partner graminicide occurs there is no advantage of adding this graminicide to JUDO for blackgrass control, and JUDO even at 2.1 litres/ha will not give acceptable levels of control in these circumstances.
Mixing and Application:
Shake the container thoroughly before opening and use. Half-fill the spray tank with clean water and begin agitation. Add the required quantity of JUDO to the water. Rinse the empty container thoroughly with water and add the rinsings to the tank. Complete the filling and spray immediately. Maintain agitation while travelling and throughout the spraying operation. Do not allow the spray mixture to stand. Thoroughly wash all spraying and measuring equipment with water immediately after use.
