Large tires moving at high speeds are the biggest source of air turbulence behind the sprayer. This year, PAMI is conducting further field experiments with a new 120-foot boom John Deere.

Sprayer speed a turbulent topic

As sprayers go faster, aerodynamics start to come into play. A PAMI project is evaluating if they affect spray deposition

Reading Time: 3 minutes On the surface, spraying seems straightforward. But a closer look at the multitude of factors that can influence how best to get product from the spray tank to the plant surface reveals something akin to a massive puzzle with a couple of pieces missing. One of the people trying to make that picture complete is […] Read more

Leading insecticide cuts bee sperm by almost 40 per cent

By
Reading Time: < 1 minute The world’s most widely used insecticide is an inadvertent contraceptive for bees, cutting live sperm in males by almost 40 per cent, The Guardian in the UK is reporting. Citing research led by Lars Straub at the University of Bern, Switzerland, the report says neonicotinoid pesticides were found to cut the lifespan of the drones […] Read more

Pest Patrol: Sensitivity of inter-seeded annual ryegrass and red clover to corn herbicides

#PestPatrol with Mike Cowbrough, OMAFRA

By ,
Reading Time: < 1 minute Research has been done in the United States and Canada to determine the tolerance of cover crops to various soil-applied corn herbicides. This article provides an overview of the results of that work, and provides some consensus across the different locations. Two important factors influence the potential for carryover injury to rotational crops: The sensitivity […] Read more

New Technology: More options provide greater grower flexibility

By
Reading Time: 3 minutes Each new year tells its own tale and offers a new mix of tough cropping decisions, with the hope of a perfect growing season and higher yields. Weed and disease management are constant challenges for growers, however, particularly with changing species, the risk of resistance and the impact of weather throughout the growing season. The […] Read more

Integrated Pest Management gaining credibility

More and more growers are beginning to embrace the IPM approach to insect control, and the system is beginning to bear fruit

By
Reading Time: 7 minutes A few years back Owen Olfert and other entomologists approached a group of growers with what might have seemed like an outrageous request — don’t spray for wheat midge. They were in the process of introducing a new parasite to knock back midge populations, but there was a problem — the critter in question was […] Read more

France moves toward all-out ban on neonics

By
Reading Time: 2 minutes Paris | Reuters — French lawmakers approved plans for a total ban on some widely used pesticides blamed for harming bees, going beyond European Union restrictions in a fierce debate that has pitched farmers and chemical firms against beekeepers and green groups. The EU limited the use of neonicotinoid chemicals, produced by companies including Bayer […] Read more

We need to get our herbicide resistance response right

Dealing with what's become a global problem could end up being one of Canada's key competitive advantages as a grain-exporting nation

By
Reading Time: 7 minutes In Australia, the problem is so bad growers are catching chaff with mechanical seed destructors or burning it in windrows in order to destroy weed seeds. In the U.S. Cotton Belt, the unthinkable has happened and crews walk through fields, hand-roguing Palmer amaranth at $150 per acre. In Europe, they’re resorting to more and more […] Read more

Maximum residue levels an issue that’s coming to a head

New trade agreements should be good for horticultural product exports, but fuzzy rules around MRLs could become non-tariff barriers

By
Reading Time: 5 minutes Mention maximum residue levels (MRLs) to a grower or a chemical company representative, and you’re likely to receive a frustrated response. In spite of trade deals between continental jurisdictions, the MRL issue continues to be a stick in the cogs of the smooth operation of trade agreements. The Trans-Pacific Partnership (TPP) or the Comprehensive Economic […] Read more

Pest Patrol: What advances in precision agriculture would benefit weed control?

#PestPatrol with Mike Cowbrough, OMAFRA

By
Reading Time: 2 minutes Auto steer and real-time kinematics (RTK) that allow an operator to repeatedly get within millimetres of a target are, to me, the most obvious investment that you could make to improve the efficiency of mechanical weed control practices like inter-row cultivation. Operator fatigue and accidental damage to the crop would be greatly reduced by integrating […] Read more

Feds scrap ‘conditional’ pesticide approvals

By
Reading Time: 2 minutes Federal crop chemical regulators this summer will stop granting “conditional” registrations for new pesticides — a practice already largely on the way out, they note. Health Canada, which oversees the federal Pest Management Regulatory Agency (PMRA), said Tuesday it plans to stop granting new conditional registrations starting June 1, describing the move as an “important […] Read more
