Messina buying weed

Mullewa growers Andrew and Rod Messina have been on a long and dedicated journey of weed management. Their 12 thousand ha dryland cropping enterprise is based on a predominantly sandplain soil type and the region generally expects to mm annual rainfall, but seasonal variability is often a challenge. The most recent innovations to be tested and adopted are real-time and localised herbicide application technology and impact mills for harvest weed seed control. Photo: Fiona Mann. Over the years their efforts to reduce the weed burden across their controlled traffic farming operation have also included narrow windrow burning, chaff carts, autumn tickles, crop topping and double knocking glyphosate. When herbicide resistant wild radish populations established on the farm the Messinas added pre-emergent to the in-crop herbicides in their weed management strategy. In the family sold their collection of chaff carts and bought three Integrated Harrington Seed Destructors iHSD in anticipation of a harvest dominated by cereals across 10, ha. The impact mills performed well through the harvest and the Messinas are very pleased to have dispensed with burning chaff dumps for harvest weed seed control. At the same time they have also moved into camera spot-spraying technology, initially for summer and fallow spraying but also for future potential for in-crop spot-spraying. Their new litre Agrifac Condor Endurance II machine is equipped with weed-identifying cameras developed by French firm Bilberry, allowing for real-time weed detection and tailored herbicide application. The system — called AiCPlus — uses optical cameras and microprocessors to identify weeds ahead of the metre spray boom. Individual nozzles are then triggered as the boom passes overhead to spot spray the weeds. The cameras are fixed at 3 m apart, with each linked to the independent operation of nozzles within a set of 12 nozzles. Arriving on farm in January , a little later than expected, the Messinas used it to finish the summer weeds program on about ha of their sandplain soils.

Its target was wild radish growing in paddocks of Scepter, Devil, Chief and Zen wheat. With each pass, the cameras captured images that depicted both the crop and weed at different times of day and under various light conditions. These images are being used to better inform the algorithm behind the technology. In the Messinas will be working with Bilberry to gather images to identify blue and white lupin in wheat crops. For the trial, they had allowed the radish plants to grow to a size that the cameras could easily detect, approximately 10 cm 2 , with the sprayer first being put to work on a paddock with a high weed burden, something that they would not usually do. In paddocks with high weed burdens, their aim is to knock out weeds early in their growth via a blanket spray, in a bid to conserve crop-available moisture. This would usually occur around the three-leaf stage in wheat. Andrew expects the efficiencies from green-on-green technology to come in subsequent sprays that targeted the low number of radish plants from later germinations. In these paddocks, Andrew said a blanket spray would generally not be necessary. Having the impact mills fitted to their harvesters gives the Messinas full confidence to be involved with the development of the weed identification and spraying technology because they know that any weeds that escape treatment will be destroyed at harvest. The 48 m Agrifac sprayer runs on the same trams as the harvester rather than the trams used by their other sprayers. The family started exploring soil constraints in , mainly to determine if soil acidity, aluminium toxicity or nutrient deficiencies were limiting yields. Testing uncovered pH levels of around 5. Non-wetting properties and compaction were also identified as potential limiting factors. They then embarked on a liming and mouldboard ploughing program to adjust the pH, treat non-wetting and bury weed seed. Their soils now feature pH levels in the range of 5. The overall result is better soil, better crop competition and less weeds. Andrew says the deep ripping has the potential to bring weed seed back to the surface, but this has only been evident on the edge of tram lines in a couple of paddocks where brome grass has re-surfaced. The Messinas aim to stop seed set at every stage of the crop production and weed life cycle.
