OTHER PESTS Brown pasture looper (Ciampa arietaria) - P a s t u r e s Brown pasture loopers are major pests of legume pastures and minor pests of legumes, oil seeds and cereals. Loopers feed on feed on foliage, capeweed b eing their favoured host. Young caterpillars feed on the leaf surface near the hatching site, where as older caterpillars may migrate from adjoining paddocks. They will devour the entire leaf tissure leaving scalloped leaves, reducing plant density and vigour. C u t w o rm (Agrotis s s p . ) photos © NSW Agriculture Cutworm larvae Loopers usually have only one life cycle per year. The adult lays small cream coloured eggs in autumn, these are usually laid in groups or rafts on dry grass stalks. The moth is a grey/coppery colour about 20mm long with delicate rounded wings and is strongly attracted to light. The larvae is grey/brown to green in colour with black and cream longitudinal stripes. Young loopers move with a looping motion, however adults (40mm long) do not. The main period of activity is late autumn to early spring. looper adult - Cereals and Field Crops Cutworm are a native insect pest of cereals and field crops. The adult is a stout bodied moth with a wing span of approximately 3 cm. The larvae live for about 1 month before pupating. They are characteristically smooth, plump and grey/ green colour with a pink tinge. When fully grown, they can be up to 50mm long and curl up when disturbed. During the day they can be found just under the soil surface or in leaf litter, often close to a damaged plant and partly chewed leaves. They feed at night, chewing through emerged/ e m e r ging plants - often felling the plant at ground level. The Solution Apply FA S TAC Duo with a minimum of 50 litres of water per hectare when infestations reach an economically damaging level. The Solution Emerging and establishing crops should be checked for caterpillars crawling on the soil surface and feeding on seedlings in the late afternoon and evening. Apply FASTAC Duo at the label rate with a minimum of 50 litres of water per hectare in the late afternoon or evening for best results. FA S TAC DUO 1 8
OTHER PESTS Vegetable weevil larvae We b w o rm (Hednota s p p . ) - Cereals We b w o rm larvae are pale to deep brown, tinged by gut contents with a black or dark brown head. When fully grown, the larvae are approximately 15mm long. The larvae are often found in web lined tunnels from which plant parts may protrude. They can be seen above ground when conditions are cool and damp. photo © NSW Agriculture photo © NSW Agriculture Vegetable weevil (Listroderes diff i c i l i s ) - Canola The adult has a typical weevil snout and is a dull, grey /brown colour approximately 10mm long with two small white blazes on its back. Larvae are yellow to green in colour with a flattened, slug-like body and a small brown head. Eggs are laid in autumn and develop into larvae in the winter. These l a rvae live up to two months before pupating. When the adults emerge, they feed until the summer when they hibernate until the following autumn. The Solution Crops should be inspected as they emerge. Border sprays are often required to control invading adults. Apply FA S TAC Duo at the label rate when cotyledons and leaves are being eaten or the plant lopped. Adults are difficult to kill so more than one spray may be required, in particular if migration from untreated areas occurs. Webworm larvae The Solution P r e - s o w i n g : E ffective control can be achieved if webworm is identified in fallow. Apply FA S TAC Duo at the label rate with a minimum of 100 litres of water per hectare. Do NOT apply to dense pasture. A minimum of 3 days should be left between spraying and sowing. FA S TAC Duo is compatible with Roundup † a n d Spray Seed † . Post Emergence: Apply FA S TAC Duo at the first sign of economic damage. If 25% of the plants show signs of damage, at or after emergence, spraying should not be delayed as the continued feeding will kill many plants, resulting in bare ground and thin areas. Most damage occurs within 3 weeks of emergence and during this period the crop should be inspected every 2-3 days. 1 9 FA S TAC DUO
