Graham Parsons, pollinator biosecurity specialist with the Saskatchewan agriculture department, reported results of studies conducted in co-operation with the Saskatchewan Forage Seed Development Commission when he spoke recently at the commission’s annual meeting.
He also said the lesser clover leaf weevil can be better controlled by night spraying because that’s when it’s active in the upper part of plants, according to reporter Becky Zimmer of the Western Producer newspaper.
“So it’s kind of a win-win both ways, better for the pollinators and better for spraying for the pest as well,” Parsons said.
“If you can spray at night or early in the morning, just as the sun comes up, or in the evening as the sun’s going down or after it’s gone down, then all the pollinators, they’re home for the night so they’re not going to be exposed to anything when you’re spraying,” Parsons said.
