Farm Table says:
What is the problem?
With the 3D’s weed management publication, its effectivity merely hinges on the farmer’s careful actualization of the provided methods.
This paper supplied four different case studies of farmers who effectively managed Paterson’s curse in grazing systems in the real world.
What did the research involve?
It is comprised of four case studies and how they dealt and successfully eliminated Paterson’s curse thriving in their plants. It includes these farmers various ways of actualizing the 3D’s: Deliberation, Diversity in the Approach, and Diligence.
What were the key findings?
Case study 1 – Pinelea:
The Scott’s purchased two irrigation blocks that were both highly infested with Paterson’s curse. They continued his father’s utilization of Paterson’s curse control program but because of its high-expenditures, they developed different strategies to control it.
● Deliberation – They faced salinity and erosion and identified that the blocks that were previously grazed by cows were the source of the Paterson’s curse.
● Diversity – They used spraying with a broadleaf herbicide, carefully managed the grazing and fed the sheep with grain during autumn while paddocks are set-stocked, and pastures are monitored.
● Diligence – Taking into account, their net benefit of Paterson’s curse control is $15,500 annually. It is also due to their continual monitoring and follow-up.
Case Study 2 – Winona
After a major bushfire at Winona, Paterson’s curse spread in the plants, Colin sprayed his plants with herbicides but it only increased pasture maintenance costs and didn’t protect the bare ground that flourishes seed set. Consequently, he was motivated to try different strategies in managing the weeds.
● Deliberation – He enrolled in a Grazing for Profit™ and attained understanding in planning a strategy in grazing and maximizing the performance of his pastures and livestock.
● Diversity – Colin managed the pasture cropping system for protecting the ground, used timely grazing in matching the available pasture and animal requirements, and used herbicide.
● Diligence – Due to subsequent monitoring, the result of his approach increased for 55% in stocking rate and 20% reduction in crop establishment costs. His net benefit is almost $62,000 per year.
Case Study 3 – Marombi
Marombi’s infestation of Paterson’s curse threatened their pastures and livestock productivity. The Ords then implemented a whole-of-farm control program
● Deliberation – They were aware that uncontrolled smalls areas are prone for reinfestation, that’s why they should prevent the Paterson’s curse from seeding.
● Diversity – They used herbicides, spray glaze, crop and pasture rotations, biological control, and competitive pastures. They monitored potential weed entry points and treat new infestations swiftly.
● Diligence – With their constant monitoring and follow-up, the costs estimated is $15,000 but the annual net benefit is $130,000.
Case Study 4 – Mill Beck
About 15% of the Griffins’ property is highly infested and 30% are moderately infested with Paterson’s curse. Di then developed a whole farm plan for Mill Beck’s infestation.
● Deliberation – The infestation source is from the hay and monitored weed changes and formed an organic weed control strategy.
● Diversity – They released five biological control agents, used mulching cutting, spot weeding, crash grazing by goats, cultivate crops, and pine oil spraying.
● Diligence – They kept the weed-areas clean and made creek banks and boundaries for eradication.
These four case studies definitely proved that even their own approach accorded from their appropriate understanding in regards to weed management helped them to prevent and halt the spread of Paterson’s curse. This is achieved because of their persistence through monitoring, maintenance, and motivated as the keys to their success.
