Non-Renewal of Diquat (Reglone) Approval

According to the August 31 bulletin from the U.K.’s Agriculture and Horticulture Development Board (AHDB), Reglone’s days are numbered, says Eugenia Banks, a potato specialist with the Ontario Potato Board. “Loss of the active ingredient Diquat will be a significant blow for European potato growers, as it is an effective desiccant, which helps achieve skin set—such a key requirement for successful storage—and cuts down the risk of disease spread immediately prior to harvest,”…

PMRA to Conduct New Mancozeb Re-Evaluation

August 19, 2018—After a June 2018 decision to restrict the use of Mancozeb on a wide variety of food and feed crops, including tomatoes, the Pest Management Regulatory Agency will conduct a new Mancozeb re-evaluation for stakeholders’ consultation, says Eugenia Banks, a potato specialist with the Ontario Potato Board. The June decision also restricts Mancozeb use on ornamentals, oilseed, and fibre crops, as well as in forests and woodlots. Mancozeb is a…

Canadian Grain Commission Invests Surplus Funds in the Harvest Sample Program

Canadian producers will have access to even more information on the quality of their harvest thanks to enhancements to the Canadian Grain Commission’s Harvest Sample Program. Beginning in the 2018-19 crop year, producers who participate in the Harvest Sample Program will receive falling number and deoxynivalenol (DON) results for their wheat samples at no cost. With this additional information in hand, producers will be better able to market their crop to ensure…

‘Canadian Potato Growers Made Wise Planting Decisions,’ Says Grower Organization

Statistics Canada released the first official estimate of planted Canadian potato acreage for 2018. Planted acreage nationally is slightly up +0.5% and is estimated to be 347,416 acres, compared to 345,817 acres planted in 2017. “It overall reflects improved demand for processing products,” says the general manager of the United Potato Growers of Canada, Kevin MacIsaac. He says the slight increase further indicates that producers “have made wise planting decisions after assessing…

Enormous Potato Production Potential in Africa

Since 1990, the acreage used for potato production worldwide has increased by 40%. The delivered volume has also doubled. Over the same period, the trade value of potatoes has shot up by 400%. Dr Maximo Torero is the World Bank’s Executive Director. He says that, in a large part, this imbalance of increasing production versus the increasing value of potatoes can be found in the frozen product sector. “The most significant increase…

Multi-Species Cover Crop Blend for Rotation in the Canadian Potato Provinces

Soil organic matter has become a popular topic of discussion in the past year. In Ontario, a report from late 2016 indicated soil organic matter (SOM) levels in many parts of the province are at 15-year lows, coinciding with increasing interest in the use of cover crops, reduced- or no-till management and longer rotations in the past three to five years. On Prince Edward Island, the issue of low SOM levels is…

Registration granted for a potato seed treatment to help manage pink rot

Syngenta Canada Inc. announces the registration of Revus fungicide as a potato seed treatment for the suppression of pink rot and control of seed-borne late blight in potatoes. Pink rot is a soil-borne disease caused by the pathogen Phytophthora erythroseptica that thrives in wet, poorly drained soils. Infection typically takes place pre-harvest, as the pathogen enters tubers through the stem end and lenticels. Tubers infected with pink rot will often decay during harvest and…

Influencing Potato Tuber Numbers

(The following content belongs to Yara International ASA and is part of Yara Potato Plantmaster. For more information visit www.yaracanada.ca) The numbers of potato tubers produced by each potato plant is influenced by agronomy and varietal potential. A large number of tubers per hectare will produce a crop of predominately small tubers, ideal for canning, salad or seed potatoes. A relatively low tuber number provides less competition per unit area and allows…

Growth Regulator Update

Use of the growth regulators MH (maleic hydrazide) and CIPC (chlorpropham) are integral to the potato industry, but there is always room for improvement – and even new avenues of use as the chipping industry evolves. First, let’s look at how MH works and how it is best applied. MH is effective in preventing sprouting as long as there is enough green foliage to translocate the chemical. It can be applied too…
