A contact and residual post-emergence herbicide for annual broad-leaved weed and meadow grass control in sugar beet and fodder beet. A suspo emulsion formulation containing 150 g/l (13.8% w/w) phenmedipham, 50 g/l (4.6% w/w) desmedipham and 200 g/l (18.4% w/w) ethofumesate.
DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
Restrictions and warnings
Do not apply to crops suffering from stress. This may be due to a number of factors e.g. nutrient or trace element deficiency such as manganese, soil acidity, drought, periods of low temperatures or frost, substantial day to night time fluctuations, high light intensity, wind or hail damage, use after other herbicides, pest or disease attacks.
Do not apply when temperatures exceed 21ºC or in strong sunlight. If treatment is essential, delay spraying until the temperature falls and light intensity reduces.
An interval of at least 5 days must elapse between applications of SNIPER™.
SNIPER contains three active ingredients with different modes of action and, therefore, the risk of resistance building up is reduced. SNIPER contains ethofumesate, a Group N herbicide and desmedipham and phenmedipham which are both Group C1 based on the mode of action classification system of the Herbicide Resistance Action Committee.
Repeated use of herbicides with the same mode of action can increase the risk of strains of weeds developing resistance to these compounds, leading to poor control. In order to minimise the risk, a strategy for preventing and managing such resistance should be adopted.
Growers are advised to apply products containing herbicides with different modes of action in sequence, as co-formulations or in tank-mix where two or more components are active against the target weeds.
Use the recommended rate of SNIPER and the correct application timing for the hardest to control weed species present in the field. The above should be used in conjunction with effective cropping rotation and cultivation techniques e.g. stale seedbed, cultivation and use of non-selective herbicide prior to drilling.
Further guidance on weed resistance management is available from the Herbicide Resistance Action Committee (HRAC) and Weed Resistance Action Group (WRAG). Follow WRAG guidelines.
For best results the largest weeds should not be beyond the fully expanded cotyledon stage at spraying. Occasional larger weeds will usually be controlled by a full series of SNIPER sprays, provided that at the first treatment they are not larger than the maximum sizes shown below. On soils containing more than 10% organic matter, the residual activity of SNIPER may be reduced.
Weeds killed up to 6 expanded true leaves Charlock Fat-hen
Weeds killed up to 4 expanded true leaves Black-bindweed Pansy, Field
Weeds killed up to 2 expanded true leaves Dead-nettle, Henbit Dead-nettle, Red Field-speedwell, Common Groundsel Fool’s parsley Speedwell, Ivy-leaved Knotgrass Redshank
Other weeds controlled
Chickweed, Common: killed up to 10cm across or high. Cleavers: killed up to 5cm across or high. Mayweed: severe check or kill up to 2.5cm across or high. To improve weed activity in cool conditions or against less susceptible weeds, the addition of a suitable adjuvant e.g. Toil is recommended.
Crop specific information
SNIPER may be used on all sugar beet and fodder beet varieties.
SNIPER can be used on all soil types. On soils containing more than 10% organic matter, the residual activity of SNIPER may be reduced.
Time of application
The first application of SNIPER should be made when the crop has reached the fully expanded cotyledon stage.
The recommended time of application is at the fully expanded cotyledon stage of the largest weed present. A single application of SNIPER will not give season-long control. Subsequent applications should be made as each flush of weeds reaches the cotyledon stage. Susceptible weeds may not be killed by the first treatments but may be checked and then controlled by later applications.
Rate of Use
Maximum individual dose 1.3 L/ha
Maximum total dose 3.9 L/ha
Water volume At least 100 L/ha
Beet crops may be sown at any time following the use of SNIPER. Three months must elapse before any other crop is sown, and mould-board ploughing to a depth of 15cm must precede seedbed preparation.
Mixing and spraying
For use by tractor mounted/trailed sprayer only. Add the required quantity of SNIPER to a quarterfilled spray tank with continuous agitation, then add the remaining volume of water. Continue agitation during spraying. Ensure that all spraying equipment is thoroughly washed out immediately after use by triple rinsing with water, then drain the tank. On emptying the container, RINSE CONTAINER THOROUGHLY by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely. Use a FINE spray as defined by the BCPC system. Avoid spray drift. Take care to avoid overlapping.
SNIPER is compatible with the following products: Goltix 70 SC SNIPER + metamitron For improved residual activity, metamitron may be added to SNIPER applications in a low volume postemergence programme. Always read the label of the partner product carefully before use.
