Biosecurity Group Opens Proposed Pest Rate Consultation in Mundijong

There was some great conversations between landowners and Peel Harvey Biosecurity Group (PHBG) at the first public consultation for the proposed declared pest rate.

 

Pest Rate Consultation events list

 

A few larger landholders were concerned that landholders would be charged at a proportion of the unimproved value of their land (i.e. ad valorem). They were relieved to find out the charge would be a flat rate, and it would be fixed (i.e. not vary according to property size).

 

 

The Peel Harvey Biosecurity Group believe in a community wide approach to pest management and believe that a small flat/fixed rate for properties one hectare and above is fair. Controlling declared pests sustains the economic, environmental and amenity values of an area, protecting the reasons landholders chose to live there in the first place.

 

Landholders were encouraging towards education and engagement of the community. Many landholders who are committed to controlling pest animals and plants find trouble arises through shared property boundaries with absentee landholders and new lifestyle block owners. Many times a positive heads up with some help to find resources and to know where to start is all that is needed. The PHBG is committed to providing resources, support, and educational events to help landholders in the region learn about effective control options that are available.

 

 

The Peel Harvey region is large and covers many different land uses. This means pest priorities can change across the landscape.  While someone in Harvey may be focused on cotton bush, a resident in Serpentine may be most concerned about foxes. As a community based group with committee members from each Local Government Area the PHBG understands the complexities of declared pest management across the region. The PHBG is happy to discuss with landowners how the proposed pest rate can benefit them, as well as their community.

 

While it may be frustrating to think of the proposed declared pest rate as another ‘tax’ a landholder has to pay, realistically there is no secured, ongoing funding for the control of established declared pests. The big positive is for every dollar that a landholder contributes, the State Government will match it. All funds will be used specifically in the Peel Harvey region on declared pests, according to an operational budget that is approved annually.

 

The Peel Harvey Biosecurity Group has more consultation events planned across the Peel Harvey region – you can look on the PHBG website or Facebook page for more information. Alternatively you can email questions to comms.phbg@gmail.com.

July edition of Backyard Buddies released

The Department of Primary Industries and Regional Development release a monthly guide to animal and plant pests, diseases and weeds. The July edition of Backyard Buddies focuses on preventing weeds by using mulch in your garden.

The header promting the Backyard Buddies Newsletter

Winter rains are building up moisture levels within the soil; aiding absorption of the nutrients and minerals needed to ensure a healthy plant. Weed seeds are also benefiting from this rain as it helps to provide the optimal conditions for weed germination.

The secret to successful and cost-effective weed control is to strike early, and nothing is earlier than prevention. So it’s important to implement weed management practices in your garden and understand the importance of using clean mulch from a reputable source.

Mulch is commonly used as a protective layer to maintain soil moisture by minimising evaporation. Mulch also prevents weeds by limiting the light required for weed establishment. However, contaminated mulch and the incorrect use of mulch can introduce new weeds into your garden or encourage existing weeds to germinate.

Ask questions of mulch suppliers or retailers to help avoid purchasing mulch contaminated with weed seeds.  Mulch that has not reached the optimal temperature required to kill most weed seeds, is not frequently turned or is left uncovered, poses a risk of weed contamination.

Composted mulch or mulch containing large quantities of plant debris and soil are not effective at weed suppression.  These act more like a soil they can compact and retain water; providing the perfect conditions for weeds to germinate and prosper.

If looking to suppress weeds, choose coarser mulch.  This is commonly made from chunks of wood or bark, and applied up to 4 inches deep.

You can also help protect your garden and our State by reporting suspicious or unusual weeds that pop up after fertilising or applying mulch to the Department of Primary Industries and Regional

Development (Previously the Department of Agriculture and Food WA) using our free mobile app MyWeedWatcher, or report via the department’s Pest and Disease Information Service by calling 1800 084 881 or email info@agric.wa.gov.au.

Pests and rides feature at Harvey Show

The Peel Harvey Biosecurity Group attended the 2017 Harvey Agricultural Show. Our enthusiastic committee members, made up of local property owners and representatives from the Shire of Murray and Harvey, tended the stall .

Committee member Marion Lofthouse reported that the day was very successful with new cotton bush infestations reported, “we were able to hand out lots of bumper stickers to interested community members as well as hand out control notes on cotton bush and other weeds”. Marion was also surprised to discover that although many community members were aware of the group through the Peel Harvey Biosecurity Group banners, strategically placed around the Peel-Harvey region, community members were still unaware of what cotton bush actually looked like. Marion says ” when they came to the stall to ask us what cotton bush actually looked like I could show them some cuttings and our potted samples to show them”.

 

Cotton bush

Narrow leaf cotton bush (Gomphocarpus fruticosus) is a declared pest in Western Australia (WA).

The Peel Harvey Biosecurity Group is looking forward to attending other community shows in 2017 and the events the group are attending can be found in the events section of our website.

Declared weed infestations can be reported by contacting your local biosecurity group or via the MyWeedWatcher App.

 

Robinia suckers popping up in a suburban lawn

Global invader controlled by kero concoction

Robinia pseudoacacia L. (black locust) is recognized as a global invader due to its ability to colonise areas quickly, produce lots of seeds, and produce suckers when disturbed. It’s ability to fix nitrogen in the soil allows Robinia to spread into low quality soils, once used to reclaim disturbed sites, the plant is now recognized as a weed on most continents. Many gardeners plant Robinia species because of their golden appearance and large colourful flowers, however these species are grafted onto black locust root stock which produce thorny suckers when the roots are disturbed. These suckers can even pop up into neighboring yards 15m away causing disputes, some of which has led to civil action.

Don Burke, of Burke’s Backyard, lists the global invader Robinia as one of the trees gardeners will regret they planted!

Control Options-

Robinia suckers can pop up vigorously after soil disturbance with sharp thorns that can make removal even harder.
The Ask Sabrina section of The Weekend West advised that a concoction of 200ml of blackberry and tree killer mixed with one teaspoon of kerosene painted on to the cut sucker immediately, is very effective. Hard-to-kill plants such as oleander and tree of heaven are also susceptible.

Website Herbiguide give this control advice “Cut down the tree and paint the stump with neat glyphosate to reduce regrowth and suckering. Spray regrowth and suckers when they are about 500 mm tall with glyphosate. It re grows vigorously from cut roots and stumps and these sprouts need to be removed continually to exhaust the root system. Access, Grazon and metsulfuron are worth a trial.”

The Meat and Livestock Association of Australia rates Robinia as moderately  palatable for goats in their handbook titled Weed control using goats- a guide to using goats for weed control in pastures. Giving a chemical free option for weed control.

Heath Benefits?

According to some the black locust has some health benefits and parts of the tree can be used for different therapeutic uses. Infusions  can help burning in the stomach, and with fatigue and nervousness. The flowers can apparently help with wounds and burns- this could be helpful after attempting the removal of thorny suckers.

A pile of pulled out cotton bush

Post fire weed control successful with industry grants help.

Agricultural landholders and land managers in the local government areas of Waroona, Harvey, Murray, Serpentine-Jarrahdale and Mandurah were invited to apply for grants to support their efforts to control weeds in early 2017.

An applicant from the Cookernup area said that  “spraying went really well and successfully knocked off the larger cotton bush plants. Now that the summer grass has died off it is easy to see the young emergent cotton bush and we are keeping on top of these by walking the area once a week.” The program had great feedback being easy and straight forward in the application process and the rolling out of the grant funding. The property owner reported that the “..fire although devastating did remove the larger Apple of Sodom plants that had been difficult to remove and its a high priority not to let the weed get established again. Of course weed control is always ongoing especially with the recent rainfall”.

Another applicant from the Yarloop area also had a good experience with the grant program. The applicant stated that ” the contractors provided through the program were fantastic, very knowledgeable and experienced. The contractors were able to effectively control cotton bush in a very steep and rocky area of our property. They were so good we even had them back to spray weeds in the wet areas on our property”. These contractors Western Conservation PTY Ltd can be found on Facebook and have a range of environmental management services they offer.

Grants from $100 to $1500 were available for the purchase of herbicide, spray packs or the hiring of an appropriate weed control contractor for successful applicants. The grants were available for landholdings used primarily for agriculture or horticulture. Below are two applicants of the program sharing their experiences. The grant was a coordinated program combining the Peel Harvey Biosecurity Group, Peel Harvey Catchment Council and Greening Australia. Funding was supplied through the Australian Government’s National Landcare Programme.

 

 The Peel Harvey Biosecurity Group wish all applicants luck with their weed control support provided through the grants and look forward to hearing more success stories in the future.

Local farmer spreads weed message at field day

The cotton bush and Apple of Sodom field day on the 5th of October was the Peel Harvey Biosecurity Group’s most popular event to date. With over 60 people attending, the focus was the management and control of some locally common declared weeds- cotton bush and Apple of Sodom. The  event personified the interest and need of the community for help in controlling declared weeds, real experiences both positive and negative were shared providing integral information for local property owners.
Property owner Mike reminds us all that the “Best way to manage weeds is to take ownership of your own weed problems and that’s what we are doing.”

The Peel Harvey Biosecurity Group looks forward to holding more informative events like this one in 2017. Become a member today so you don’t miss out on upcoming events and biosecurity information.

Harvey Reporter in the October 11th 2016 Edition.

Wokalup couple Anne and Wayne Slammers speak with Department of Agriculture and Food development officer Andrew Reeves.

LANDOWNERS came from as far as Serpentine and Bridgetown to a field day on the treatment of declared weeds cotton bush and Apple of Sodom in Brunswick on Wednesday.

Landowner Mike Donaghy and his wife Kylie West had tried a variety of methods to combat the infestation they found when they bought the property seven months ago.

With support from the Peel Harvey Biosecurity Group and the Department of Agriculture and Food, WA, Mr Donaghy offered to share his experiences with other stakeholders and get the message across that the problem can only be solved with a community approach.

“I got rid of cotton bush and Apple of Sodom in one paddock and now find wild radish and wild mustard taking root,” he said.

“The best way to solve the problem of declared weeds spreading is to take ownership of the weeds on our own land.

“As farmers we share the responsibility and we don’t want to spread highly invasive cotton bush to our neighbours.”

Biosecurity group chairman Vaughn Byrd said the turnout of almost 80 people was amazing.

“It was an interactive way where Mike shared his experiences and this prompted others to share theirs,” he said.

“I talked to a number of people and they were very happy with the day.

“In some instances it clarified for them that they were on the right track controlling weeds.

“The field day was very timely – cotton bush is no longer seasonal and landholders have to be proactive all year round.

“If you leave the weeds until they flower, you have left it too late.”

Barley Grass weed

The 4 major weeds you don’t want in your hay.

Hay season has finished and lovely yellow rectangles and rolls dot the hills and flats of the Peel Harvey region, but don’t be taken in – hay can hide a multitude of weeds you could be introducing onto your property.  Movement between properties of hay, animals and machinery are some of the most common ways weeds are transported through the environment.  All property owners should have specific property biosecurity plan in place to restrict the movement of weeds and pests.

One persons weed can be another persons treasure, but there are weeds that can be toxic to livestock and owners should be aware of what these look like. There are a few things to restrict the likely hood of introducing weeds onto your property through your hay. They include educating yourself on what weeds can look like when baled up in hay, checking out the verges and adjoining proprieties for weeds of your hay supplier, and asking questions about the baling process and the quality of the hay.

Four major weeds you could find in your hay-

 

Patersons Curse  (Echium plantagineum)

Integrated weed management

Tactic name

Most likely % control (range) Comments on use
Crop choice and sequence 85 (0–95) Avoid planting barley in infested areas
Herbicide-tolerant crops 80 (40–95) Triazines and imidazolinone herbicides provide useful control in tolerant crops
Burning residues 50 (0–75) Dropping chaff and straw into windrows improves control
Inversion ploughing 90 (70–99) Use skimmers to ensure deep burial
Delayed sowing 60 (50–90) Level of control depends on autumn break. Use in combination with Tactic 2.2a

 

These herbicide and control recommendations are from the Department of Food and Agriculture’s website. Follow the link for more information or to look up control notes for different weeds. When using herbicides remember to use the correct safety equipment and always read the Material Safety Data Sheet for the chemical you are using (available by law through any stockist).
