For the control of broad-leaved weeds, especially cleavers, in listed cereals, forage maize and in grassland.

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.
Barclay Hudson 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.
Growing Conditions
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.

Weather and Growing Conditions
Optimum results with Barclay Hudson 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 Barclay Hudson is to be applied alone in cereals without the benefit of a product in tank-mixture giving complementary activity on cleavers. Do not apply Barclay Hudson during periods of cold nights or if frost is forecast.

Do not roll or harrow crops within seven days of treatment with Barclay Hudson.

Undersown Crops
Do not use Barclay Hudson on crops undersown with clovers or other legumes. Barclay Hudson may be used on crops undersown with grasses only provided that these are firmly established and are tillering.

Application (BCPC definitions)
Apply to dry foliage. Do not spray if rain is imminent. Avoid spray drift onto nearby crops or areas. Avoid overlapping spray swaths.
Do not use on crops grown for seed production.

Cereals and forage 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.

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.

Barclay Hudson is compatible in tank-mix with the following approved formulations. When tank-mixing Barclay Hudson 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 Barclay Hudson 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 maize.

Do not sow peas, beans, clovers or any other legume for 12 months on land treated with Barclay Hudson at 2.2 l/ha (28 fl.oz). All manure or crop residues derived from crops treated with Barclay Hudson at 2.2 l/ha (28 fl.oz/ac) must be returned to grassland or land to be cropped with cereals. All straw from crops treated at 2.2 l/ha must not be incorporated back into the soil.

Care of Sprayer
Directly after each days use with Barclay Hudson, 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 Barclay Hudson 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.
