Pests and weeds can be easily introduced and spread onto the farm when you bring in grain, fodder or livestock.
When buying fodder or feed grain, be aware of where it originally came from and inspect it for pests and weed seeds.
The main risk is during dry seasons when fodder is transported long distances from other localities with different pest problems. Buy locally whenever possible to avoid importing new pests to the region.
When buying grain, ask the seller about pests that are present on their farm or in their crop. If possible, obtain a vendor declaration of weed status or have a sample checked by a seed/plant testing laboratory. If in doubt, have the grain cleaned.
It’s good practice to always put out feed for animals in the same place each time. Inspect this area for new weeds or pests regularly.
New livestock should be isolated in a holding paddock for at least 10-14 days to contain any weeds transported on fleeces and coats and allow any weed seeds to pass through their digestive system. Weed seeds will germinate after rain or in the next growing season and should be treated before they produce seed.
Isolation of new or returning stock can be combined with procedures to minimise introducing new animal diseases onto a property such as drenching to control parasites. Ideally, the holding paddock should be near the house so that regular checks can be conducted on the animals themselves and to control any weeds that may have been introduced.
All livestock movements onto and within the farm should be recorded in a stock diary. Boundary fences and gates need to be maintained to prevent animals from straying. Any stray or potentially sick animals should be isolated as soon as possible.
Always wash and disinfect hands before and after coming into contact with livestock.
