Arbiter is a translocated herbicide for the control of broad-leaved weeds, especially cleavers.

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.

Arbiter is a translocated herbicide taken up by the leaves of weeds. It is essential that the target weeds have fully emerged before application and that good spray cover of the weed foliage is achieved. Weeds which emerge after application are not controlled.

Best results are achieved against small weeds growing actively under warm, moist conditions; these conditions are particularly important for the control of cleavers. Ensure that crops are vigorous with growth unaffected by frost, pests, disease, nutrient deficiency or moisture stress before treatment. Do not treat waterlogged crops or crops under drought stress.

Optimum results with Arbiter can only be achieved when weeds are actively growing under good soil and weather conditions and the crop is vigorously competitive. These conditions become especially important if cleavers are to be controlled, more so if Arbiter is to be applied alone in cereals without the benefit of a product in tank-mixture giving complementary activity on cleavers. Do not apply Arbiter during periods of cold nights or if frost is forecast.

Do not roll or harrow crops within seven days of treatment with Arbiter.
UNDERSOWN CROPS Do not use Arbiter on crops undersown with clovers or other legumes. Arbiter may be used on crops undersown with grasses only provided that these are firmly established and are tillering.

Apply to dry foliage. Do not spray if rain is imminent. Avoid spray drift onto nearby crops or areas. Avoid overlapping spray swaths. Apply as a MEDIUM spray at 2-2.5 bar (30-35 psi) by conventional hydraulic ground-operated sprayer. Do not use on crops grown for seed production

Cereals and forage and grain maize: apply as a MEDIUM spray at 2-2.5 bar (30-35 psi) by conventional hydraulic ground-operated sprayer in 170-340 l/ha water to give good coverage of the target weeds; increase the spray volume to 300-400 l/ha water when treating volunteer potatoes. Use the higher spray volume for application in dense crops or when weeds are large or have become hardened. Apply to dry foliage.

Grassland: apply as a MEDIUM spray at 2-2.5 bar (30-35 psi) by conventional hydraulic ground-operated sprayer in 200- 400 l/ha, using a minimum 300 l/ha on established grassland, to give good coverage of the target weeds. Use the higher spray volume for application in dense crops or when weeds are large. When overall spraying is not justified, small weed infested areas or individual weeds may conveniently be spot treated by knapsack sprayer or hand lance connected to a powered conventional hydraulic sprayer. Preferably use a flood jet to avoid spray drift. Spray to just wet the weed foliage evenly but before run-off occurs.

Arbiter is compatible in tank-mix with the following approved formulations. When tank-mixing Arbiter with a partner, the Directions for Use of the partner product must be strictly observed, together with the Directions for Use of this label. Mix Arbiter in the spray tank first except when mixing with wettable powders, suspension concentrates or water dispersible granules unless directed otherwise. Spray out immediately after mixing. Do not tank-mix with any herbicide when treating triticale or forage and grain maize.

Do not sow peas, beans, clovers or any other legume for 12 months on land treated with Arbiter at 2 l/ha (28 fl.oz). All manure or crop residues derived from crops treated with Arbiter at 2 l/ha (28 fl.oz/ac) must be returned to grassland or land to be cropped with cereals. All straw from crops treated at 2 l/ha must not be incorporated back into the soil.

R Directly after each days use with Arbiter, wash out the sprayer thoroughly with clean water and a wetting agent recommended for the cleaning of sprayers. Traces of fluroxypyr left in the sprayer may damage susceptible crops when the equipment is subsequently used.

Pour the required quantity of Arbiter into the spray tank already half-filled with water and under agitation. Top up the spray tank with water to the required level. Maintain agitation during spraying and until the tank is sprayed out. 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 the container safely.
