Over the next week most growers across P.E.I. should start harvesting and storing potatoes, Donald said. Farmers will get a better idea of the yield closer to Halloween when the harvest ends. READ MORE
A tractor trailer with more than 40,000 pounds of fresh produce will leave Prince Edward Island for Georgia where it will be distributed to victims of Hurricane Irma.
"The PEI Potato farmers always rise to a need and this is no exception, even during the busy harvest time," said Rodney Dingwell, chairman of the PEI Potato Board. "We have a very generous industry and it gives me great pride that we are so quick to respond when someone is in need. Not only with our own communities, but as far away as the southern U.S." READ MORE
Company president Robert K. Irving said it is a big deal for agriculture in Alberta.
"Our business will grow from 6,000 acres of potatoes today, with our present land, up to over 15,000 acres," Irving said at the new plant's groundbreaking earlier this month. "Those 9,000 acres, it's an opportunity for the local farmers, the growers in the region, to really look at the opportunity to grow and expand their operations here and have a long-term future with potatoes."

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
Enviroot's goal is to reduce waste by using food remains, especially potato peelings, to make a safe material for use in the home.
The company received a national business prize of $20,000 from Enactus Canada, a student-led entrepreneurial organization, and the McCain Social Enterprise Project Partnership to get the project going this summer.
"We use the potato peels that we get from McCain Foods here in New Brunswick in our particle board as a kind of filler," said Justin Trueman, Enviroot CEO and fourth-year biology student.
The potato peels are plasticized by melting them a little bit, and a bond between the potato peels' particles is created.
This allows them to bind products together without need of formaldehyde, which is the glues of some household furnishings, walls and stairs made from composite wood materials. 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.
What is late blight?
Late blight is a disease caused by an organism that produces a white fuzz on the underside of leaves which releases millions of spores that float through the air to infect other plants. The spores land on a susceptible leaf, germinate, and cause brown oily lesions. The spores splash on the ground and infect potato tubers, which become brown and rusty looking, with a granular texture. Crop losses due to late blight can cost the Canadian potato industry tens of millions of dollars annually.
Protecting the potato industry
AAFC late blight specialist Rick Peters says taking steps to prevent the disease from infecting potato crops is important to help protect the health of the industry. He advises home gardeners to ensure their tomato seeds are resistant to the US-23 strain of late blight. Resistant seeds can be purchased at most garden centres. Certified disease-free seed potatoes can also be found at garden centres or purchased from a local seed potato grower. Peters says potatoes grown from last year’s garden or those bought from the grocery store are not suitable for planting as these tubers have not been tested and certified as disease-free and could be susceptible to a variety of potato diseases.
AAFC has partnered with industry leaders to identify and track late blight strains in production areas across the country. Scientists are also looking at biological characteristics of the different strains including how they respond to treatments. This knowledge allows for better management and control of the strains in Canadian potato and tomato production areas. While scientists continue to study the disease, they maintain that an ounce of prevention is worth a pound of cure and home gardeners have an important role to play.
If you spot a suspected late blight infection in your garden this season, please contact the Department of Agriculture, Aquaculture and Fisheries at 1-866-778-3762 for information on how to properly dispose of infected plants.
