DO NOT graze crops within a week before or 2 weeks after spraying DO NOT apply during cold weather or drought. DO NOT apply during rain or if rain is expected. DO NOT spray in windy weather and avoid drift onto broad-leaved plants outside the target area. HEADLAND SPRUCE is active at low concentrations. The following crops are particularly susceptible to spray drift: beet, brassicae (eg turnips, swedes, oilseed rape) and most market garden crops including lettuce and tomatoes under glass, pears and vines. DO NOT use HEADLAND SPRUCE immediately before or after sowing any crop

WEEDS CONTROLLED
HEADLAND SPRUCE is a selective herbicide for use post-emergence to control broad-leaved weeds in Cereals, Grassland, Lucerne, and Clover HEADLAND SPRUCE applied at 4.5 l/ha will control those annual weeds as listed and will control perennial weeds as indicated. Annual weeds will be best controlled if spraying is done while the majority of weeds are seedlings. Perennial weeds should be sprayed during their period of maximum growth, usually when the flower buds are beginning to form. The response of perennial weeds to treatments are often variable with only the aerial parts killed, though often suppression will occur. The recovery of weeds will be reduced if the sward is growing vigorously at the time of treatment

WEED RESISTANCE
When herbicides with the same mode of action are used repeatedly over several years in the same field, selection of resistant biotypes can take place. These can propagate and may become dominating. A weed species is considered to be resistant to a herbicide if it survives a correctly applied treatment at the recommended dose. A strategy for preventing and managing such resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacture
