Haystacks are known to spontaneously combust. These scientists are finding out why https://t.co/lXJy6FWe27

[Food Agility CRC @foodagility]

We're in Wagga Wagga today with our project team, @CharlesSturtUni, @IAGAust and @MyriotaGlobal, gathering some vital information about haystack fires.

Stay tuned for more details, and find out more about the research project here ⤵️

@CharlesSturtUni @IAGAust @MyriotaGlobal A big thanks to @VicvicPetro of @abcnews for coming along and covering the research yesterday.

@gsandral @agrobaz @JasonBrand Yes we can have a look at this. Collect seed from a number of surving plants and we can spray them with a number of options at CSU

[John Broster @JohnCBroster]

@paulretired1951 @johnbroster No journal papers but three honours theses so far, more coming

[John Broster @JohnCBroster]

@mjgoodenco All to be sown with disc seeded

[John Broster @JohnCBroster]

One stripper front 2021-22 research site re-established after harvest. Measuring wind speed at two heights, air temp at four, soil temp at two and soil moisture at one plus a heap of plant and stubble measurements from now until next harvest

[John Broster @JohnCBroster]

The first 1500 pots of sow thistle from the 2020 GRDC herbicide resistance survey have sown and are now being counted before spraying. These are for one herbicide only, another two after this, then the wild oats. Some results this year all done by end 2022. #herbicideresistance

[John Broster @JohnCBroster]

Third year of stripper front compared with Draper front trials underway. First site for the year set up measuring wind speed, air and soil temperature and soil moisture.

[John Broster @JohnCBroster]

@CEBuddenhagen @zacharyngow @FARarable Chris, no we still collect the weed seeds as normal, we are confirming that the stripper fronts collect the same amount of weed seeds as a draper front and how much chaff is produced for harvest weed seed control

[John Broster @JohnCBroster]

2020 harvest research field work completed 3:00 today, 411 pdks from Wentworth to Wellington via Wagga for GRDC herbicide resistance survey, 10 pdks stripper front weed seed capture, 4 pdks chaff % and 1 pdk grazing chaff lines. Now for the lab work. #HWSC #herbicideresistance

[John Broster @JohnCBroster]

Brome grass from last year’s surveys east of the Olympic Highway in NSW and Tasmania just starting to emerge for herbicide resistance screening. Barley grass in the glasshouse next door a few days behind. Now the wait for spraying and the results.#herbicideresistance

[Grassroots Agronomy @grassrootsag]

Ideal day to check out @JohnCBroster stripper vs draper stubble trials. Wind was gusting 30-40 kph with visible differences at ground level. 2nd year of a fantastic CSU project looking at wind speed, soil temp, air temp & crop growth. @NathanHatty

Final visit of the week touring the Western Australian wheat belt looking at Harvest Weed Seed Control with a group of USA researchers listening to Ray Harrington tell his story

[John Broster @JohnCBroster]

About to spray second last batch of resistance screening for the year, wild radish, sow thistle and Indian hedge mustard to dive different herbicides. First run with the new glasshouse trolley, thanks CSU transport #herbicideresistance

[John Broster @JohnCBroster]

Wild oats from the 2018 south west slopes herbicide resistance survey are nearly ready to assess. Clethodim looking okay, only live plants are from our known resistant, clodinafop not so good. #herbicideresistance

[John Broster @JohnCBroster]

Wild oats from 2018 NSW slopes herbicide resistance survey screening is well underway. 93 populations collected, about 1000 pots all transplanted. being tested for four herbicides, fop, dim, SU and roundup. Sprayed last week. Now we wait for them to die? #herbicideresistance

[AHRI GRDC @AHRI_Team]

[NEW AHRI INSIGHT] Have you checked out our latest insight yet? Kirrily Condon from @grassrootsag has written an excellent summary of @GrahamCentre recent paper 'A quarter of a century of monitoring herbicide resistance in Lolium rigidum in Australia' ➡️https://t.co/sXHvLmAilz

[Gulbali Institute @Gulbali_Inst]

Dr John Broster explaining our herbicide resistance research to Agriculture Minister @D_LittleproudMP Great be able to showcase our work to improve sustainability and productivity of #ausag #CSUResearch

[John Broster @JohnCBroster]

Finally sowing first trial in the new GRDC glasshouses. Ryegrass from the 2018 southern slopes of NSW survey to be screened to diclofop, clethodim and glyphosate.
