Tractor Safety – “No Seat, No Rider”

There is no argument that tractors have forever changed agriculture. The use of tractors has long replaced the presence of draft horses on almost every farm in America. It is estimated that cultivation of land with a modern tractor allows 64 acres to be plowed in the time it took to cultivate one acre with a draft horse. The use of tractors also comes with a dark side. As long as farmers have been using tractors they have been injured and killed by them. The Bureau of Labor Statistics reports 274 transportation related deaths, which includes tractor deaths in 2018. In any given year half of all tractor fatalities are from overturns, almost another one-fourth are from runovers. Many have a tradition of allowing extra passengers to ride on tractors. Sometimes trying to transport a worker from one task to the next or possibly saving them from walking back to the barn. Some even allow children to come along for a ride – a very dangerous practice. Whether it be on the tongue, side steps, fender or extra passenger in the cab, remember these places are not designed for riders. As we enter one of the busiest seasons in agriculture remember one of the most important safety rules NO SEAT, NO RIDER!

  • Riders that fall off are immediately in danger of being run over by a tractor wheel
  • On rough or uneven ground, riders are first to bounce off (especially children)
  • Riders distract the driver and can bump controls
  • Rollover Protective Structures are designed to protect drivers, not riders

Do not ever think “it won’t happen to me.” Every farmer can tell a story of an incident that happened to someone they know in the farm community that involves a tractor. Make sure everyone makes it through the harvest – NO SEAT, NO RIDER!

Pesticide Applicator or Dealer Storage Inventory with Cover Letter Due May 1st to Fire Department

All licensed pesticide applicators, as well as dealers, who store pesticides are required by law to send a copy of their storage inventor(ies) with an explanatory cover letter to the local fire company by May 1st each year. In New Jersey, all licensed pesticide applicators and dealers who store pesticides are required per N.J.A.C. 7:30-9.5 […]

Preparing Orchards Against the Frost – Low Tech Strategies

Frost is common in the north-eastern US, however, frost events during bloom, specifically in orchard crops can be economically devastating. Often the cause is a few hours of temperatures below the injury threshold temperature for the developing buds as cooler nights result in the rapid loss of thermal energy. Fortunately, there are several passive methods or low-tech strategies, that can help maintain a slightly higher orchard floor temperature, has the potential to prevent substantial crop loss.

Eastern Tent Caterpillar: The Landscape Harbinger of Spring

Throughout much of NJ during this week, the growing degree days (GDD) will be increasing consistently. By the end of the week, many areas will exceed 90 GDD, which means the eastern tent caterpillars will begin to hatch. Not all eggs will hatch at once since a staggered hatching period will potentially increase survival rates if the weather happens to cool again.

The photographs of the eastern tent caterpillar’s life cycle included in this blog were all taken during the spring of 2016 at the same site in Freehold, NJ. They are placed in chronological order covering a time span of 10 weeks from 1st egg hatch on 3/23/16 to late pupation on 6/2/16. In 2016, central NJ experienced a relatively warm early spring that enabled the speedy first hatching.

Date: 3/23/16 (No hatch). Do you see it? One inch long Tent Cat egg mass overwinters encircling 2-3 year old twigs. (Photo Credit: Steven K. Rettke, Rutgers Coop. Ext.)

This Week’s Changes and Updates to Relief Programs that Impact Farmers

This past week brought several changes and updates to relief programs that impact farmers. This blog from the University of Minnesota is a good summary of changes and announcements by USDA on relief programs that impact farmers and includes links to websites with more information: https://blog-abm-news.extension.umn.edu/2021/03/paycheck-protection-program-extended.html.

The American Rescue Plan Act uses the 2501 definition of “socially disadvantaged”, which includes Black/African American, American Indian or Alaskan native, Hispanic or Latino, and Asian American or Pacific Islander. Gender is not a criteria in and of itself, but of course women are included in these categories.

Nursery Pest Scouting Guide: 60-150 Growing Degree-days & Boxwood Blight Information

Pest Scouting:

Please print or download the two resources of this post (click on them)

The information provided in the downloads gives scouting ranges (in growing degree days, base 50F) for specific insect pests harming nursery crop production and maintenance. Additionally, forecasting predictions (GDD50 accumulation) for calendar dates of multiple regions of New Jersey (S,N,C) are provided.

To determine your local growing degree-days, please review this postObtaining your local growing degree-day information”

Scouting Ranges:

  • This document supports scouting, it does not replace it. Keeping good notes on pest development will help dial in scouting and treatment efforts at your local level.
  • It is important to note that these GDD50 are not exact, rather provide a range of GDD and subsequent calendar dates that can be used to scout for, and treat for, insect pests.
  • The pests listed here will be listed again in future scouting range announcements as they undergo further developmental life stages or are vulnerable to management options.
  • If you need more information, OR you are regularly seeing specific pest development stages at growing degree-days different than those listed here, please contact Tim Waller at twaller@njaes.rutgers.edu
