State-of-the-art weed detection tech could be available within few years

The research collaboration between Bosch and Bayer is helping farms turn digital

The research collaboration between Bosch and Bayer is helping farms turn digital

New technology which will apply state-of-the-art weed detection to apply herbicide more accurately could be available for use by 2020.

As part of a three-year research partnership between two German agricultural and tech giants, Bayer and Bosch are developing smart spraying technology.

Using camera sensors, it can differentiate between crops and weeds and target weeds with pesticides – at lightning speed, in a single process. It is hoped the technology will be available by 2020.

“Smart spraying sustainably clears fields of weeds. This safeguard yields while minimising environmental impact,” Dr. Markus Heyn, member of the Robert Bosch GmbH board of management, said.

The rise of such technology is seen as an important step forward as agriculture leaders advance innovations that are climate-friendly, to reduce the industry’s carbon footprint.

World hunger is also a growing problem for the industry. According to predictions made by the Food and Agriculture Organisation of the United Nations (FAO), farmers will have to sustainably generate around 50% more yield by 2050 in order to feed the global population.

“We want to venture together with Bosch into new territory, combining different technologies to ensure that herbicides are only applied in areas where they are really necessary,” Tobias Menne, head of digital farming at Bayer, said.

‘Field manager’

The technology solution will offer a digital “field manager” which assesses the field and recommends the best time to treat weeds.

Weeds can be difficult to identify, but by using camera sensors, the technology can determine what is growing in the field and then adopt a targeted application technique to spray crop protection agents specifically on weeds.

The multiple camera sensors, which are spread across the entire width of the crop sprayer, take a continuous series of pictures, identifying the different weeds and allowing the optimum treatment to be defined.

While the crop sprayer is still crossing the field, the herbicide is sprayed in the required quantity and mixture using the appropriate application parameters.

While the relevant weeds are targeted, weedless areas remain untouched. All this occurs within milliseconds.

‘Quantum leap’

“Smart spraying is a quantum leap in the fight against weeds,” said Björn Kiepe, head of agronomy at Bayer’s digital farming unit.

“We are combining modern weed identification technology with the ability to apply different active substances as the situation demands. This process is very precise, with a spatial resolution of well under one meter. This will make it even easier for farmers to practice sustainable crop protection.”

Bosch has been transferring its automotive technology to the agriculture industry, and is already generating sales worth 1 billion euros as a result.

By the middle of the next decade, it plans to double sales of technologies for agriculture. “Bosch can do more than cars and cordless screwdrivers. We are bringing high tech to farms, opening up a market worth billions,” said Dr. Markus Heyn.

New report reveals cost of Fall Armyworm and provides recommendations for control



The report, commissioned by the UK’s Department for International Development (DFID), reviews the current evidence of the potential impact of the pest and quantifies the likely economic effect on agricultural sectors in affected countries and regions if left unmanaged.

In the absence of any control methods, we estimate that the pest has the potential to cause huge maize yield losses in Africa and we expect it to spread throughout suitable habitats in mainland sub-Saharan Africa within the next few cropping seasons. Northern Africa and Madagascar are also at risk. This would clearly have a huge impact on food security and the achievement of SDG 2 (Zero Hunger).

Control of Fall Armyworm requires an integrated pest management (IPM) approach and immediate recommendations we make in the report include raising awareness on Fall Armyworm symptoms, early detection and control, and the creation and communication of a list of recommended, regulated pesticides and biopesticides to control the pest. Work must also start to assess which crop varieties can resist or tolerate Fall Armyworm. In the longer run national policies should promote lower risk control options through short term subsidies and rapid assessment and registration of biopesticides and biological control products.

Why integrated weed management is critical

WEED MANAGEMENT: Director of the University of Sydney’s Weed Research program Dr Michael Walsh says HWSC plays an important non-chemical role in stopping weed seeds from entering the soil seedbank.

WEED MANAGEMENT: Director of the University of Sydney’s Weed Research program Dr Michael Walsh says HWSC plays an important non-chemical role in stopping weed seeds from entering the soil seedbank.

An integrated weed management approach is essential to manage hard-to-kill weeds, avoid costly, ineffective control measures and preserve the life of herbicide chemistries.

 AN integrated weed management approach that incorporates herbicide and non-
herbicide tools is critical if growers are to manage hard-to-kill weeds, avoid costly, ineffective control measures and preserve the life of important herbicide chemistries.



University of Sydney’s Weed Research program director Dr Michael Walsh said herbicide resistance was an escalating problem in the northern grain growing region. While growers in Queensland and NSW have traditionally faced fewer problems than their western counterparts, that’s rapidly changing, he said.

Dr Walsh has played an integral role in developing one of Australia’s leading non-herbicide weed management tactics, harvest weed seed control (HWSC), which focuses on the capture and destruction of weed seeds.

“Annual weeds such as ryegrass, wild radish, brome grass and wild oats have adapted to cropping systems, growing to similar heights as cereals and maturing at the same time,” Dr Walsh said.

GRDC VIDEO: Integrated weed management explained.

HWSC plays an important non-chemical role in stopping weed seeds from entering the soil seedbank and can dramatically reduce the emergence of hard-to-kill weeds in the following season.

“It involves collecting, destroying or burning weed seeds that are present at harvest and is particularly effective on problem species such as annual ryegrass and wild radish. There can also be a significant impact on the more difficult to collect species such as black oats, and brome grass.”

A new tool to help growers incorporate HWSC into their weed management program is now available with the release of a GRDC Know More video explaining the use and benefits of HWSC.

“Methods range from something as simple as a chute on the back of the harvester to more complex systems such as a mill system which is integrated into the rear of the harvester,” Dr Walsh said.

“My advice to anyone just starting out is to start simple and assess how HWSC techniques can be effectively incorporated into the management program before advancing to something like the Integrated Harrington Seed Destructor, chaff carts or even a bale direct system.

“By keeping weed seed loads low, growers can greatly reduce the risk of herbicide resistance development, and potentially protect the efficacy of important herbicide chemistries for decades.”

NZ government funds targeted weeding initiative.

Killer drones coming – for weeds

It’s a vision straight out of a sci-fi movie: a fleet of drones criss-crossing a farm, scanning the ground below for weeds and when they are found zapping them with a laser-beam.

However, the New Zealand government is spending $NZ1 million in the hope of making that vision a reality. The Ministry of Business Innovation and Employment is giving the money to a partnership between government research organisation, AgResearch, the Universities of Auckland and NZ-based technology firm Redfern Solutions to examine the development of such technology.

Program leader Dr Kioumars Ghamkhar said the aim was to use cameras and software to identify the weeds based on their unique chemical signatures and how they reflect light, and then locate them precisely using GPS.

“From there, we think smart spraying (rather than systemic and non-targeted use of chemicals), or the right kind of laser mounted on the drone could hone in and damage the weed,” Ghamkhar said.

“We know there are lasers now available that could be suitable, and that they are extremely accurate, so if lasers are used, it would also avoid damaging the useful plants around the weed.

“The effectiveness of lasers against plants has been tested overseas before but that was in the lab, and we’ll be taking it out in the field to test and see if it works as we have planned.”

There are other initiatives underway suggesting that the weed identification, if not killing, is perfectly feasible.

IoT Hub reported last month that Netherlands-based crop spraying equipment maker Agrifac was a planning to incorporate weed recognition technology developed by French startup Bilberry, in conjunction with Nokia, CETA, Institut Mines-Télécom and Tampere University of Technology into crop sprayers sold in Australia.

Also, Hitachi Australia has developed technology that takes imagery from drone mounted cameras able to respond to a very wide range of wavelengths, analyses this data in the cloud and provides weed identity data to the farmer.

The company is looking to commercialise the service including providing the drone and training in its use to the farmer.

Earlier this year, the Electron Science Research Institute (ESRI) and Edith Cowan University in WA was reported to be close to commercialising a laser system for identifying (but not killing) weeds that used lasers of three different frequencies.
