Root-Knot Nematodes In Western Australian Horticulture, Department Of Primary Industries And Regional Development, Western Australia

Horticulture factsheets

Root-knot nematodes (Meloidogyne species, RKN) are unsegmented round worms which are usually invisible to the naked eye, but the galls they produce in infested plant roots are often easy to spot. RKNs are plant-parasitic with a broad host range, which includes vegetables, field crops, tree and vine fruits, ornamentals, pastures and some weed species.

Root-knot nematodes reduce yields of many horticulture crops, including carrot, potato, sweet potato, tomato, capsicum, pumpkin, zucchini, avocado, grapes and lettuce. RKNs favour the sandy soils common throughout the south-west of Western Australia’s (WA’s) horticultural area.

Sheep Worm Control In Wa, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Effective, sustainable control of sheep worms involves a combination of planned stock and farm management, monitoring worm burdens using faecal worm egg counts (WEC), strategic timing of drenches and the genetic selection of worm resistant sheep.

Levels of drench resistance of sheep worms in WA are some of the highest in the world and without resistance management action at individual farm level, it will continue to worsen and spread.

Although effective drench options are generally available, many sheep owners are unaware that resistance has reduced the effectiveness of worm control programs, and this can affect profitable sheep production.

Early Weaning Of Lambs In A Poor Season, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

The feed requirements of a ewe with a lamb at foot are higher than if the ewe and lambs are fed separately. In a difficult season with short feed supplies, it is better to early-wean lambs from their mothers to lower feed costs and ensure that the ewes regain condition before joining. This issue becomes even more important as the costs of feeds increase.

Ewe's milk provides the main source of nutrition for lambs until about eight weeks of age. Lambs will sample pasture from about two weeks after birth but by eight weeks of age pasture overtakes milk as …

Lupin Root Diseases - Diagnosis And Management, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Root, hypocotyl and stem base diseases can be significant problems in lupin crops, reducing stand density, plant vigour and yield. Root disease is present in nearly all narrow leafed lupin (Lupinus angustifolius) paddocks but in the majority of paddocks has only a small impact on crop development. However, in paddocks where high levels of root rot occurs, plant establishment, seedling vigour and crop yield can be significantly affected.

When a root disease is present in a crop very little can be done to manage it in that cropping season. It is therefore vital that the cause is correctly identified to …

Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

If correctly and appropriately undertaken, the destruction of rabbit warrens, or modification of the habitat so it becomes less favourable to rabbits, can be an important and effective part of reducing the impacts of rabbits.

Destruction of warrens can improve the overall effectiveness of rabbit control programs, even though many rabbits live and shelter above-ground under bushes, and in scrub). If undertaken properly, the ripping of rabbit warrens can often provide a relatively permanent and long-term benefit. Similarly, removing or modifying other forms of rabbit-harbourage (for example, removing rock piles) can help, particularly in semi-urban areas or on smallholdings.
