Based on independent field trials, from 2015 to 2017, Levity has demonstrated that their product, Potato Lono, increases potato yields by up to $1,000 per hectare. Trials were held in England, Ireland, Netherlands, and France.
Potato Lono improves photosynthesis, and helps crops increase carbon efficiency during times of stress, improving tuber initiation and bulking. This can result in increased tuber numbers, when applied during tuber initiation, with trials showing increases of over 60,000 extra tubers per hectare across various potato varieties.
"We're excited to have revealed this groundbreaking data" said David Marks, Joint MD, Levity CropScience. "Our hard work has paid off and now growers around the world will be able to benefit from this research and our innovative application of this knowledge into unrivalled, pioneering fertilizer products."
Anne Weston, Joint MD, Levity CropScience added: "Over the next few weeks, we will be attending several exhibitions to meet farmers and their advisers to highlight and discuss our results, including the fantastic benefits Levity CropScience's products offer the farming and horticultural industries throughout the world. It is another example of how our innovative Lancashire company is driving research into increasing crop yields throughout the world, which will ultimately benefit both the environment and the local population."
Usually wet seasons favour crop development, but incidence of storage rots is a concern, especially if rainfall occurs late in the growing season, advises Eugenia Banks, Ontario potato specialist.
The Honourable Carla Qualtrough, Member of Parliament for Delta and Minister of Public Services and Procurement, recently announced a $1.8 million investment with the University of British Columbia to determine carbon sequestration and GHG emissions, and develop beneficial management practices (BMPs) for increasing the efficiency of fertilizer use in blueberry, potato and forage crops.
This project with the University of British Columbia is one of 20 new research projects supported by the $27 million Agricultural Greenhouse Gases Program (AGGP), a partnership with universities and conservation groups across Canada. The program supports research into greenhouse gas mitigation practices and technologies that can be adopted on the farm.
"This project will provide new science-based knowledge on net GHG emissions by accurately measuring GHG emissions and developing mitigation technologies for blueberry, potato and forage crops in the Lower Fraser Valley. The research team will use state-of-the-art instrumentation and automated measurement techniques to quantify annual GHG emissions. While the specific research objectives are targeted to fill regionally identified gaps in knowledge, they will be applicable more broadly to similar agricultural production systems across Canada and Global Research Alliance member countries," said Dr. Rickey Yada, Dean, Faculty of Land and Food Systems, UBC.
The field trial conducted by The Sainsbury Laboratory (TSL) in Norwich involves incorporating late blight resistant genes from a wild potato relative into a cultivated Maris Piper potato. READ MORE
As an industry leader providing up-to-date information and research, TCM is looking to gather input from producers across the country in order to develop a more thorough understanding of the state of herbicide resistance in Canada.
TCM's Herbicide Use Survey will offer participants the ability to help tell the story of these important crop protection tools by having farmers like you share how herbicides are being used.
The survey takes less than 10 minutes to complete, and will ask details like soil and farm acreage, types of weeds being targeted, as well as management practices. All submissions will remain anonymous.
Those who complete the survey will be entered into a random draw for a $500 visa card! Complete the survey here.
The Herbicide Use Survey ends December 8th. Results will be collected and presented at the 2018 Herbicide Resistance Summit in Saskatoon, Sask., on February 27 and 28.
An infected potato psyllid insect carries the Lso (Candidatus Liberibacter solanacearum) pathogen that can cause zebra chip disease in potato crops.
Zebra chip has affected potato crops in the U.S., Mexico and New Zealand and caused millions of dollars in losses. Potatoes with zebra chip develop unsightly dark lines when fried, making affected potatoes unsellable.
The first detection of Lso came from sampling cards collected at one site south of Highway 3, near Lethbridge, Alta. For the full story, click here.
Close to 50 industry representatives took the opportunity to take part in the annual Variety Day at Harrington Farm showcased potential entries for the Accelerated Release program of Agriculture and Agri-Food Canada, variety trials conducted by the PEI Potato Board, as well as a tour of the organic potato acreage.
There was also a chance to view a soil building rotation trial being conducted in conjunction with the Enhanced Agronomy Initiative-- a fund established in 2016 by processing growers. READ MORE
Harvest management, in large part, is bruise management. Bruising also affects tuber quality significantly. In order to harvest potatoes with minimum tuber damage, growers need to implement digging, handling and storage management practices that maintain the crop quality for as long as possible after harvest.
Assuming all harvest and handling equipment are mechanically ready to harvest the crop with minimum bruising, there are several tips to preserve the quality of potatoes crop during harvest:
- Timely Vine Killing. Killing the vines when tubers are mature makes harvesting easier by reducing the total vine mass moving through the harvester. This allows an easier separation of tubers from vines.
- Timely Harvest. Potatoes intended for long term storage should not be harvested until the vines have been dead for at least 14 days to allow for full skin set to occur.
- Soil Moisture. Optimal harvest conditions are at 60-65% available soil moisture.
- Tuber Pulp Temperature. Optimal pulp temperatures for harvest are from 500F to 600F. Proper pulp temperature is critical; tubers are very sensitive to bruising when the pulp temperature is below 450F. If pulp temperatures are above 650F, tubers become very susceptible to soft rot and Pythium leak. Pulp temperatures above 70°F increase the risk of pink rot tremendously no matter how gently you handle the tubers if there is inoculum in the soil.
- Tuber Hydration. An intermediate level of tuber hydration results in the least bruising. Overhydrated tubers dug from wet soil are highly sensitive to shatter bruising especially when the pulp temperature is below 450F. In addition, tubers harvested from cold, wet soil are more difficult to cure and more prone to breakdown in storage. Slightly dehydrated tubers dug from dry soil are highly sensitive to blackspot bruising.
- Reducing Blackspot Bruising. Irrigate soil that is excessively dry before digging to prevent tuber dehydration and blackspot bruising.
- Bruise Detection Devices. Try to keep the volume of soil and tubers moving through the digger at capacity at all points of the machine. If bruising is noticeable, use a bruise detection device to determine where in the machinery the tubers are being bruised.
- Do not harvest potatoes from low, poorly drained areas of a field where water may have accumulated and/or dig tests have indicated the presence of tubers infected with late blight.
- Train all employees on how to reduce bruising. Harvester operators must be continually on the lookout for equipment problems that may be damaging tubers. Ideally, growers should implement a bruise management program that includes all aspects of potato production from planting through harvest.
- Harvest when day temperatures are not too warm to avoid tuber infections. Storage rots develop very rapidly at high temperatures and spread easily in storage. If potatoes are harvested at temperatures above 27o C and cool off slowly in storage, the likelihood of storage rots is increased. If warm weather is forecast, dig the crop early in the morning when it is not so warm.
The warm conditions has slowed the harvest of some processing fields, to prevent bringing warm tubers into storage. The seasonal accumulated precipitation has been 50-70% of normal in the potato growing areas (Fig1). The soils are generally on the dry side (Fig 2), but irrigated fields have sufficient moisture for a good harvest. READ MORE
Researchers are hoping Canadian potato growers will soon be able to use an innovative approach to control wireworms. This method uses just a few grams of insecticide per hectare applied to cereal seeds that are planted along with untreated seed potatoes. It provides very good wireworm control for the whole growing season, with a lower environmental risk than currently available insecticide options.
"We're into our second week of wet weather and really there's nothing being done at the present time," says Rodney Dingwell, chair of the P.E.I. Potato Board. | READ MORE
