For the control of a range of caterpillar pests in vegetable brassicas, maize, sweetcorn and tomatoes, thrips in onions, aphids in stone fruit and tomatoes, and grass grub beetle on non-bearing fruit trees, vines and non-flowering newly planted shelter belts

PRODUCT INFORMATION
Alpha-Scud Insecticide is a pyrethroid insecticide particularly active against caterpillars, thrips, aphids. Alpha-Scud Insecticide provides a rapid knockdown combined with a good residual effect. Because Alpha-Scud is not systemic, good coverage is essential to obtain control.

DIRECTIONS FOR USE
Since Alpha-Scud has no systemic action thorough spray coverage of all foliage is essential for optimal results. Dilution rates are for high volume spraying to run-off. For concentrate spraying, adjust the dilution rates accordingly. 

VEGETABLE BRASSICAS
Pest: Diamond back moth (Plutella xylostella) White butterfly ({Pieris rapae) Tomato fruitworm (Helicoverpa armigera) Greasy cutworm (Agrotis Ipsilon)
Rate: 200-250 ml/ha in a minimum of 700 litres of water per hectare
Critical Comments: Apply on a 14 day schedule from transplanting. Use only after mid-January based on crop monitoring. Use in alternation with a non-synthetic pyrethroid product. Gradually increase the spray volume per hectare as the plants grow to ensure thorough coverage of all the foliage. Use a non-ionic wetting agent. Refer to wetting agent label for specific instructions. For cutworm apply once at the first sign of damage. See Resistance Management comments.

MAIZE AND SWEETCORN
Pest: Greasy cutworm (Agrotis Ipsilon) Armyworm (Mythimna separata) Corn earworm (Helicoverpa armigera)
Rate: 150-200ml/ha in 300 to 600 litres of water per hectare. For aerial application to maturing crops, use at least 100 litres of water per hectare.
Critical Comments: For cutworm apply immediately damage to seedlings is noted. Preferable apply in early evening and direct spray to the base of the plants and surrounding soil. If used before 7 January, ensure no spray drift onto headlands where corn earworm may be living. For armyworm apply immediately pests appear, and use high water rates to ensure penetration of the spray to the base of the crop. For corn earworm apply immediately pests appear on the silks. Repeat every 10-14 days as dictated by pest activity. Use only after 7 January and if crop monitoring shows need. See Resistance Management comments

ONIONS
Pest: Onion Thrips (Thrips tabaci)
Rate: 150-200 ml/ha in a minimum 500-600 litres of water per hectare
Critical Comments: Use only after mid-January. Apply when pests appear and repeat every 14 days or as dictated by pest activity. Use the higher rate when thrip numbers are high. Use in alternation with a non-synthetic pyrethroid product. Use a wetting agent to ensure good coverage of plants including the base of leaves. See Resistance Management comments.

PASTURE
Pest: Tasmanian Grass Grub larvae (Aphodius tasmaniae) 
Rate: 100-150 ml/ha
Critical Comments: Apply in the Autumn at the first appearance of grubs and pasture damage. Use the high rate when larvae are more than 10 mm long. 

Pest: Red legged earth mite (Halotydeus destructor)
Rate: 50 ml/ha
Critical Comments: Apply when mite damage (leaf bleaching ) is noticed, especially on legume seedlings.

STONE FRUIT
Pest: Green peach aphid (Myzus persicae)
Rate: 20 – 25 ml/100 litres of water
Critical Comments: Apply only in the pre-flowering period. Apply at first sign of aphid infestation and repeat as required at 10-14 day intervals. Use the higher rate when aphid numbers are high.

TOMATOES
Pest: Tomato fruit worm (Helicoverpa armigera) Aphids
Rate: 20-30 ml/100 litres of water with a minimum water rate of 600 litres per hectare
Critical Comments: Use only after 7 January and if crop monitoring shows need. Use the high rate when pest activity is high and/or when larvae are 10-20 mm long. Repeat application if monitoring shows need. Gradually increase the volume of application as the crop matures to ensure good coverage. A spray pressure of at least 420 kPa is required to ensure good penetration of foliage and effective coverage of crop. See Resistance Management comments.

WITHHOLDING PERIODS:
BRASSICAS AND TOMATOES DO NOT APPLY LATER THAN 3 DAYS BEFORE HARVEST.
SWEETCORN: DO NOT APPLY LATER THAN 7 DAYS BEFORE HARVEST.
ONIONS: DO NOT APPLY LATER THAN 14 DAYS BEFORE HARVEST
DO NOT GRAZE PASTURE WITHIN 7 DAYS OF TREATMENT OR CUT FOR STOCKFEED WITHIN 14 DAYS OF TREATMENT. DO NOT GRAZE OR FEED TREATED MAIZE OR SWEETCORN STUBBLE TO LIVESTOCK WITHIN 14 DAYS OF APPLICATION. DO NOT APPLY TO STONEFRUIT AFTER THE APPEARANCE OF THE FIRST FLOWER OR TO KIWIFRUIT AFTER CRACKING OF FLOWER BUDS (FIRST VISIBLE PETALS).
