For the past 15 years Lorsban 500EC has been the product of choice for protecting wireworm damage. When applied directly to the plant cane setts and the adjacent soil within the planting furrow, a "zone of protection" is created. This ensures the best possible insect protection. This protection is critical during the first 6 to 8 weeks of early growth and development. Lorsban 500EC reduces the need for troublesome and expensive jobs, like manually replanting gaps within rows, or having to replant whole rows or sections. Benefits of Lorsban 500EC

over total crop when infestation is widespread. When pests are moving
as an "army" treat a broad strip over and in advance of the
infestation. Late stage instar: Use higher rate when
larvae 3cm in length. Apply follow-up treatments as required. |

PEARS: Prevention and treatment for black spot, light brown apple moth, wooly aphid, mealy bug. |
![]() Pears infected with black spot. |
Pear scab / Black spot. This fungal disease overwinters in fallen leaves
and fruit. Then in early spring, after rain, the spores are released to
settle on young leaves and flowers. Infection is evident within 2 to 3
weeks. |
To provide the best protection and reduce the
likelihood of resistance, alternate of tank mix with a protectant cover
spray. The 'reach back' action of Rubigan will treat new and 4 to 5 day
old infections, as well as giving 4 days forward protection. Rubigan is
rainfast once it has dried and , because of its systemic action, it can
continue protecting your crop even after heavy rain. Light brown apple moth. Pale yellow caterpillars create large blemishes
on the surface of the fruit which eventually become callused. For effective
control, use Lorsban 500W Insecticide water soluble packs and apply as
full a cover spray at intervals of 2 weeks, commencing at calyx. Woolly aphid. The woolly growth is actually a secretion which
hides the aphid and heavy infestations result in poor fruiting and damaged
wood. Excreted honeydew promotes sooty mould, which cuts off light to
the tree, so spray promptly - and thoroughly with Lorsban*
500EC Insecticide when you first notice an infestation. San José scale. Nymphs and adults feed on both foliage and fruit,
producing a red discolouration on the surface of the fruit and reducing
the tree's vigour. For best results, apply Lorsban 500EC as late as possible
in dormant period. Then in mid to late November, apply to coincide with
crawler activity. Repeat when necessary. Ensure thorough coverage of all
branches, foliage and fruit. Mealy bug. Control mealy bug as early as possible, targeting
crawlers rather than adults. |
| APPLES: Prevention and treatment for black spot, powdery mildew, light brown apple moth, mealy bug, scale, apple dimpling bug, woolly aphid. |
![]() Apples infected with black spot. |
Apple scab / Black spot. It's there, dormant through winter, in leaves and
rotting fruit under trees. When spring weather is warm and wet, the spores
are ejected into the air to settle on the young leaves and flowers where
they can do most harm. |
Rubigan is rainfast
once it has dried and because of its systemic action it can continue protecting
your crop even after heavy rain. The 'reach back' action of Rubigan will
actually treat any disease which has occurred over the past 4 to 5 days,
as well as giving your crops a full 4 days forward protection. Powdery mildew. During winter, this fungus survives in dormant
buds and resumes growth in spring, so it is vital to control the problem
during spring and summer with Rubigan. |
![]() Apple shoot infected with powdery mildew. |
![]() Apple dimpling bug on Delicious apple bud. |
Light brown apple moth. Found in many different fruit crops during the
growing season, these moths produce pale yellow caterpillars which protect
themselves in curled leaves secured by a silken thread. |
APPLICATION RATE LORSBAN 500W: Apple dimpling bug. Watch for this tiny 2mm long, green winged insect
from spur burst, as the main danger is from early pink through to petal
fall. Young fruit is punctured by the bug, which feeds by sucking sap.
The punctured area fails to develop as the fruit grows, leaving sunken
'dimples'. For effective control apply Lorsban 500W as a full cover spray
before flowering. Woolly aphid. After overwintering in the roots of the trees,
woolly aphids move up in spring to infest developing new wood and destroy
buds by sucking the tree's sap. Incidentally, the woolly growth you see
on the wood is actually a secretion which hides the aphid. Heavy infestations
result in poor fruiting and damage to leaf-bearing wood. San José scale. Both nymphs and adults cause damage, feeding on
foliage and fruit. This feeding produces a red discolouration on the surface
of the fruit, as well as reducing the tree's vigour. For best results,
apply Lorsban 500EC as late as possible in dormant period - then in mid
to late November, apply to coincide with crawler activity. Repeat when
necessary - always ensuring through coverage of all branches, foliage
and fruit. |
| GRAPES: Prevention and treatment for powdery mildew, light brown apple moth. |
Powdery mildew. The most common fungal disease of grapevines in
Australia, powdery mildew can live on the vine all year (in infected buds
in winter) and comes into its own in warm spring weather. While most noticeable
on young leaves, the disease will spread to the grapes, leaf stalks, tendrils,
canes and bunch stems. Apart from the distinctive soft grey / white powder
on fruit and leaves, diseased canes will display a web - like dark stain
which turns reddish as the canes mature. For effective control Rubigan
should be applied at least once prior to flowering, preferably twice,
14 days apart. As part of a resistance management program apply a minimum
of 3 Rubigan sprays per season. These should be alternated with sprays
of wettable sulphur. Light brown apple moth. Found in many different fruit crops during the
growing season, these moths produce pale yellow caterpillars which protect
themselves in curled leaves secured by a silken thread. The caterpillars
web leaves and fruit together while they're eating - and feed on the large
fruit surface, leaving blemishes which eventually become callused. |
![]() Grape bunch infected with powdery mildew. |
![]() Grape leaf infected with powdery mildew. |
| CITRUS: Prevention and treatment for California red scale. |
Both crawlers and adults cause damage, sucking
on all aerial parts of the tree. This results in severe leaf yellowing
and fall, fruit blemish and branch dieback. For best results, apply Lorsban
500EC through a high volume sprayer to the point of run-off during the
November - March period. Two sprays may be required if infestation is
heavy. |
| WEED CONTROL: |
Safety for vines and trees of all ages. Spray Surflan
on weed-free soil. However, if young weeds are noticed at application,
add a knockdown herbicide. Surflan won't damage the buds or fruit on your
trees and vines - or the earthworms that improve the quality of your soil.
Weeds controlled include: Grasses: barnyard grass, love
grass, guinea grass, paradoxa grass, pigeon grass, spiny burrgrass (gentle
annie, innocent weed), summer grass (crab grass). Surflan is compatible with many other residual and knockdown herbicides, eg: residual herbicides - simazine, oxyfluorfen and diuron; knockdown herbicides - glyphosate and paraquat. Crops protected include: Apples, almonds, apricots, bananas, cherries (not
SA), grapes, grapefruit, nectarines, oranges, peaches, pears, pecans,
plums (prunes), roses, walnuts. Verdict Herbicide. Verdict Herbicide offers growers proven control
of annual and perennial grass weeds. It shows excellent selectivity to
horticultural plantation crops and is compatible with a wide range of
herbicides, fungicides and trace elements. Verdict provides rainfastness
within one hour of application and an ability to spray right up to harvest.
When applying Verdict, spray should be directed to the base of the tree
or vine avoiding contact with fruit and foliage. Best results are achieved
when grass weeds are small and actively growing. Do not spray grasses
which have begun to flower or are under stress. Verdict can be applied
by either a boom spray or by hand gun for spot spraying. When using a
boom sprayer, apply Verdict in sufficient water to obtain good coverage
(50L to 150L/ha). Use the higher water volumes when treating large dense
infestations. |
