Insects To Watch For In 2020

Jan 29, 2020

Manitoba Agriculture & Resource Development has been on the road this winter talking about which insects to watch for during the 2020 growing season.

Entomologist John Gavloski gave his forecast for grasshoppers.

"Levels have gone up in the last two years. Going into 2020, we're advising just to get out there in June, scout your ditches, your areas outside the field where grasshoppers may overwinter, pasture lands. Levels have been increasing, whether they continue to increase or not, depends on weather and natural enemies."

He also discussed cutworms.

"Populations have been increasing. The way cutworms cycles usually work is we get three or four really bad years and usually populations after that start tapering off and that's often driven by natural enemies. So, I'm hoping we've peaked."

Flea beetles were also talked about.

"We had very heavy populations last year, there's really not a great way to monitor and accurately forecast what will happen in the next year but what we usually advise farmers and agronomists to do is consider what was present in August and September when you were harvesting your crop."

Video: Air Command Section Control for Pro-Force Spreaders

This patented section control system uses air to divert material on to different areas of the spinner disks for precise 4-section control, for an economical design by eliminating the need for added conveyor belts or movable spreader components. The section control uses the Raven RCM ISOBUS controller and a customer’s field boundary and coverage map to automatically turn off any of the four sections at any time to avoid applying valuable fertilizer in areas where it’s not needed.

This results in fertilizer savings which means more money in your pocket for a maximum Return On Investment. The powerful blower fan sends air through a 4-section manifold while the conveyor automatically speeds up or slows down as sections are turned on or off for consistent and precise fertilizer application.

• The revolutionary patented Air Command section control utilizes a pneumatic system to accurately place fertilizer onto the spinner disks to give you individualized 4-section control of your spread pattern.

• Pinpoint accuracy of four individual sections allows you to operate the system with ease. This robust design with few moving parts offers no gimmicks, just real-world results.

• The new Air Command section control option is available on pull-type models 2250 and 1850 with the new PTO drive system, and on 1450, 1250 and 1050 pull-type models with standard single hydraulics.

• Continue to do it all with the Unverferth pull-type Pro-Force Spreader. Use the Air Command section control for spreading fertilizer and in-seeding applications, while converting to single-section lime or litter application in a matter of minute
