Pest | Control thresholds | Sampling recomendation | Additional notes |
---|---|---|---|
Caterpillars: brown pasture looper | 10-12 loopers per m2
| Examine plants, old litter and soil surface in 0.5m of row. Repeat at 5-10 sites | Larvae may migrate into crop edges from nearby capeweed |
Caterpillars: cutworms | 2-3 cutworm per m2 | Examine plants, old litter and soil surface in 0.5m of row. Repeat at 5-10 sites | Apply as soon as pest is noticed at threshold levels |
Lucerne flea | Consider control measures if holes are increasingly being found on leaves | Inspect 0.5m of crop row. Look for characteristic holes in leaves. Repeat at 5-10 sites | Commonly found on soils with loam or clay texture |
Mites: Balaustium mites | Look for silvering on extensive areas of cotyledons and leaves and stress caused to plants | Cotyledons and first true leaves appear silvered and leathery, sometimes may shrivel and seedling may die. Damage occurs post emergence | Found on weeds, soil and seedlings |
Mites: clover mite | Look for silvering on extensive areas of cotyledons and leaves and stress caused to plants | Same damage as redlegged earth mite. White lines often seen on top of cotyledons. Seedling may shrival and die | Found on weeds, soil and seedlings |
Mites: redlegged earth mite | Look for silvering on extensive areas of cotyledons and leaves and stress caused to plants | Cotyledons appear 'leathery', silver, twisted shrivelled and seedlings may die. Damage may occur before seedling emergence | Found on weeds, soil and seedlings |
Slugs: black keeled slug, reticulated slug | 10 or more slugs per m2 | They are found on plants at night or hidden under clods, trash or other objects during the day | Chewed leaves or whole plants. They sometimes feed on lupin seeds at seeding.slime trails may sometime be seen |
Snails: white italian snails, vineyard snail, small pointed snail | 5 or more snails per m2
3 or more snails per m2 | Found on leaves, stems or other nearby objects | Look for chewed leaves, slime trails may sometimes be seen |
