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 SNIPER is a contact and residual post-emergence herbicide for annual broad-leaved weed and meadow grass control in sugar beet and fodder beet.
DIRECTIONS FOR USE
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 21°C 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.
Resistance
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.
Weeds controlled
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.
Soil
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
Crop
The first application of SNIPER should be made when the crop has reached the fully expanded cotyledon stage.
Weeds
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 1.3L/ha.
Maximum total dose 3.9L/ha.
Water volume
At least100L/ha.
Following crops
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
Add the required quantity of SNIPER to a quarter-filled 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.
Use a FINE spray as defined by the BCPC system. Avoid spray drift.
Take care to avoid overlapping.Compatibility
SNIPER is compatible with the following products: Goltix Flowable
SNIPER + metamitron
For improved residual activity, metamitron may be added to SNIPER applications in a low volume post-emergence programme.
Always read the label of the partner product carefully before use.
