The quick answer is NO. Sorry. There is no silver bullet. Unlike other weed problems where we have solutions, field horsetail is a plant where there is no easy answer. That’s probably the reason why field horsetail has been around since the Carboniferous age more than 300 million years ago. It is part of the ancient genus Equisetum, a prehistoric survivor and one of the toughest weeds to manage.

What is Field Horsetail?

Field horsetail is a perennial that grows from a tuber-bearing rhizome. This root system comprises actively growing rhizomes that can penetrate to greater than 1 m in depth, from which green fern-like fronds grow each year (looks like a small pine tree). Attached to the deeper rhizomes are small tubers which remain dormant while the rhizome stays alive. When the rhizome dies or becomes detached due to cultivation or other means, the tubers initiate growth to produce new plants.

Controlling Field Horsetail

It is best to get field horsetail under control before you plant. Several herbicides provide some level of top growth control ONLY because it is difficult to get the active ingredient to depths deep enough to control the rhizomes and tubers. Few herbicides are registered and their use is dependent on the situation in which horsetail grows. Continue Reading »

CleanFarms (cleanfarms.ca)

Farmers in Ontario are being offered expanded options to manage their empty seed and pesticide bags this year. CleanFARMS will be operating an extended pilot project to collect and safely dispose of empty bags, at no cost to participating farmers.

This pilot is part of the agricultural industry’s commitment to the responsible management of its products throughout their entire lifecycle and will help determine the feasibility of a permanent program.

“This pilot project will build on the solid agricultural stewardship programming that is already in place in Ontario and provide farmers with more options for managing packaging waste on the farm and contributing to long-term goals of keeping agricultural waste out of landfills,” said Barry Friesen, general manager of CleanFARMS.

CleanFARMS will collect, transport and ensure collected bags are safely converted to energy at facilities that have extensive emission controls and meet all necessary provincial and federal approvals. Farmers can contribute to a clean and healthy environment by ensuring that empty seed and pesticide bags end up in the right place. Continue Reading »

P1000636csBacterial spot, caused by a group of Xanthomonas bacteria, is an ongoing challenge for field tomato growers in Ontario. For many years, a program of fixed copper sprays was used to manage bacterial spot in plug transplants and field tomatoes. Transplant growers were advised to apply a fixed copper bactericide beginning 2 ½ weeks after seeding at 5-day intervals for a total of 5 applications. For field growers, the recommendation was to start to apply the copper within 7 days after transplanting — applying at least 3 applications at 7-day intervals. Knowing that copper and other products are relatively weak on bacterial disease, the strategy was to suppress populations early in the season while they are still low. Once symptoms are present, the bacterial populations are so high that we would not expect to have a significant impact on disease development with a spray program. Continue Reading »
