New and established pastures require dilligent pest management to ensure maximum ongoing performance. We've listed the main pasture & crop pests to watch out for.

Aphids-pg54

Aphids

EFFECT

Eat forage.

There are usually two flights per year with the first occurring from late spring/early summer and the second from late summer/early autumn. It is during the nymph stage that feeding damage occurs to plants. Brassica crop plantings from November to March are usually the most vulnerable to Aphid attack.

CONTROL

  • Ultrastrike seed treatment
  • Aphid-tolerant varieties
  • Application of insecticide
  • Recognise flight periods and control infestations early
ArgentineStemWeevil - Notman Seeds

Argentine Stem Weevil

EFFECT

Larvae appear from October onwards and feed on tillers causing them to yellow and then brown and ultimately die. Poor resulting of pasture is often mistakenly attributed to other factors such as drought. Adult weevils feed all year round on leaves leaving narrow rectangular holes in the leaves usually near the tips.

CONTROL

  • Use of Ultrastrike brassica or Superstrike Grass seed treatment to protect seedlings
  • Removal of host ryegrass plants
  • Recognise flight periods and control infestations early
  • Application of insecticide
  • Use tolerant species (cocksfoot, tall fescue)
  • Use of grasses with standard, AR1, Endo5, AR37 or MaxP endophytes
AfricanBlackBeetle - Notman Seeds
AfricanBlackBeetle---Notman-Seeds.jpg2

African Black Bettle

EFFECT

African Black Beetle larvae feed on the roots of grasses over summer causing the pasture to become loose and open and the damage appears similar to that of Grass Grub.

CONTROL

  • Use of Superstrike seed treatment to protect seedlings
  • Use of grasses with standard, Endo5, AR37 or maxPendophytes
  • Insecticide application
  • Use of a Summer forage crop (e.g. Pasja II forage brassica)
  • Use of resistant species (e.g. lucerne)
ArmyWorm---Notman-Pasture-Seeds

Army Worm

EFFECT

Armyworms are nocturnal caterpillar pests of grass pastures and cereal crops. Armyworms mostly feed on leaves, but under certain circumstances will feed on the seed stem, resulting in head loss. They should be controlled if there are rapidly expanding areas with more than 60% leaf loss.

CONTROL

  • Insecticide application in late afternoon
Black-Field-Cricket---Notman-Seeds

Black Field Cricket

EFFECT

Grass plants may be completely consumed down to the crown. Seeds and seedlings are attacked also, so areas with heavy infestations may become totally devoid of vegetation.

CONTROL

  • Application of cricket bait for Black Field Cricket control
  • Insecticide application
  • Use of a summer forage crop (e.g. Pasja II forage brassica)
Blackheaded-Cockshafer---Notman-Seeds

Black Headed Cockchafer

EFFECT

The larvae, and the damage they cause, gradually spreads out until the areas of infestation and the improved pasture species can seemingly start to "disappear" very quickly.

CONTROL

  • Use of Superstrike Clover seed treatment to protect seedlings
  • Newer cultivars with greater tolerance
  • Granular intesicide sown in the root zone
CloverNematodes - Notman Seeds

Clover Nematodes

EFFECT

Invades clover roots and cause damge at the growing tip which allows root disease to occur. Damage may result in dwarfing, discolouration, wilting and plant death.

CONTROL

  • Use of Superstrike Clover seed treatment to protect seedlings
  • Newer cultivars with greater tolerance
Diamondback Moth Notman Pasture Seeds

Diamondback Moth

EFFECT

Lay eggs in brassica plants and can cause damage to leaf and seeds. Larvae prevalent in brassica forage crops such as turnips & rape.

CONTROL

  • Removal of old brassica plants which may act as carry-over hosts
  • Application of insecticide
Red-Headed-Cocshafer

Red Headed Cockchafer

EFFECT

Redheaded cockchafers feed underground and remain below the surface, with the larvae feeding on organic matter in soil. Dead pasture amongst green pasture is the main indication of their presence. Severe damage where top soil is deeper than 6 inches & rainfall is 500mm plus.

CONTROL

  • Newer cultivars with greater tolerance
  • Deep-rooted plants such as lucerne, cocksfoot and phalaris, are less susceptible to damage.
Lucerne-Flea-Notman-Seeds

Lucerne Flea

EFFECT

Lucerne Flea move up plants from ground level eating tissue from the underside of folliage, this makes a characterisitc "small window" effect on the leaves. Sever damage can stunt or kill seedlings.

CONTROL

  • Superstrike or Ultrastrike seed treatments to protect seedlings
  • Insecticide applications.
  • Regular pasture monitoring
Redlegged-Earth-Mite-Notman-Seeds

Red Legged Earth Mite

EFFECT

Hatching of RLEM is typically after 10days of less than 20degreees and greater than 5mm rain. Feeding is by piecing plant cells and sucking out contents. Typical damage appears as silvering or whitening of the attacked foliage

CONTROL

  • Regular pasture monitoring
  • Use Ultrastrike or Superstrike to protect seedlings
  • Insectide application
Pasture Mealy Bug - Notman Seeds

Pasture Mealy Bug

EFFECT

Most damage is a direct result of feeding so that only high populations are important. infestation can be recognized from the surrounding white wax substance found in the crown of the plant.

CONTROL

  • Use  of grasses with standard, AR1, Endo5, AR37 or MaxPR   endophytes
Slugs-Notman-Pasture-Seeds

Slugs/Snails

EFFECT

Feeding takes place mainly at night, and will be shown as holes in the leaves, stems or roots. Slime is a good indication of slugs or snails.

CONTROL

  • Monitor slug numbers
  • Slug Bait application
