NJDEP Notice to Ag Businesses Regarding Open Burning April 21 2021

Due to the low temperatures predicted this evening April 21, 2021, the New Jersey DEP has issued an Open Burning Permit for Agricultural Businesses.

Note:The New Jersey Department of Environmental Protection and New Jersey Forest Fire Service caution all farmers and agriculture businesses with respect to the use of open burning in high wind velocity conditions. Please take note that farmers are encouraged to utilize smudge pots is warming as necessary during higher wind conditions. Use of open burning when wind velocity is greater than 5mph is strictly prohibited, may contribute to wildfire risk, and can carry significant penalties.

Communicating the Value of COVID-19 Vaccines With Your Farm Employees

CDC COVID-19 Vaccine Posters available in multiple languages – “Vaccines (shots) are one of the tools we have to fight the COVID-19 pandemic.”

In an effort to increase participation in the COVID-19 vaccination program among farm workers, the Centers for Disease Control (CDC), through the national Extension Foundation, is working with Cooperative Extension across the country to help spread the word about the importance of getting vaccinated. Rutgers Cooperative Extension Director Brian Schilling has enlisted a team of County Agents and Specialists to answer the call from the CDC to participate in this EXCITE program. Through a variety of communications channels we will be providing informational posters and other educational materials in several appropriate languages that you can hand out or post in locations where your workers can easily read them (like on or near your Worker Protections Standards bulletin boards or in your labor camps).

“Vaccines (shots) are one of the tools we have to fight the COVID-19 pandemic” posters from the CDC are now available on the COVID-19 page of the Rutgers NJAES On-Farm Food Safety website <https://onfarmfoodsafety.rutgers.edu/covid-19-information/> with the direct links to these multiple language editions:

You can also share this Spanish language video <https://wecandothis.hhs.gov/un-rayo-de-esperanza> from the US Dept. of Health and Human Services with your workers to help explain where they can get more information about COVID-19 vaccines. There are several other informational videos available at https://wecandothis.hhs.gov/filter/format/Video, as well as posters/fliers from https://wecandothis.hhs.gov/filter/format/Poster%20%E2%80%93%20Flyer (mostly English), and factsheets at https://wecandothis.hhs.gov/filter/format/Fact%20Sheet.

Tree Fruit IPM Report for April 20, 2021

Tree Fruit Phenology:

Tree Fruit Phenology remains about normal. In southern counties most peach orchards are at petal fall. Redhaven was at approximately full bloom on 4/12, and 90% petal fall on 4/20. Plums are past petal fall and pears are at late bloom to petal fall. Red Delicious is at full bloom. Sweet cherries are at full bloom to late bloom and tart cherries are in bloom. [Read more…]

New Harmonized and Harmonized Plus+ standards go into effect May 1

This is the time of year when growers start to think about scheduling there USDA Harmonized and Harmonized Plus+ Audits.  There have been changes to both audits which take affect May 1.  Growers should download the latest versions from https://www.ams.usda.gov/services/auditing/gap-ghp/harmonized.  The Harmonized Audit is version 2 dated February 8, 2021 and the Harmonized Plus+ with the same date is version 3.  If anyone is still getting the GAP/GHP audits there are no changes.

There are changes to both the Harmonized and Harmonized Plus+.  New questions for the Harmonized Audit include:  G-8.2, G-10.7, G-12.1, G-12.2, P-3.1, P-8.2 and P-8.4.  Amended questions include: G-3.2, G-10.1, G-10.3, G-10.6, G-10.8, G-10.10, G-10.12, G-10.16 and G-10.19.  All of these apply to the Harmonized Plus+ in addition to four new questions:  F-8.2.c, P-6.5.a, P-3.1.a and P-9.4.a.  Two questions were also amended:  G2.2.2 and G-6.1.a.

Other than the new questions which must be reviewed and addressed in the food safety plan there are certain things audits will be stressing this year.  One is G-3.2 related to documentation and protection of those documents.  Documents must be maintained for two years and be available for review.  The one document which has not been assessed in the past is the portable toilet record.  This year they will be checking for it.  There are two ways growers can comply.  First make sure the starting and ending dates are on your contract for the portable toilets.  Also, take a picture of the log inside the toilet door at least at the end of the season.  It may make sense to do it mid-season and at the end.  Maintain those photos with your other documents.

The second is F-8.2 related to cleaning and sanitizing equipment, vehicles, tools and utensils and their storage.  There needs to be a schedule for those activities and records must include the date and method of cleaning and sanitizing.  One thing that gets overlooked at times are knives for field harvesting of vegetables and herbs.  These must be included, and the auditors will be looking for the logs this year.

Example templates are being updated on the Food Safety website https://onfarmfoodsafety.rutgers.edu/ that will include most of what would be needed for an audit.  These can be modified to fit any operation.

What to Look for At Bloom: Cankers of Stone fruit.

Bacterial Spot is a key pest of Peach, Nectarine and Plum and in some years like 2019 can cause significant losses. It is caused by the bacterium Xanthomonas arbicola pv. pruni. Bacterial spot cankers that cause tip dieback (commonly called Black Tip) are often difficult to distinguish from cankers caused by other peach diseases. Other cankers that may appear during bloom are caused by the blossom blight phase of brown rot, and constriction canker. Black tip usually appears during or just after bloom. Typical symptoms are a gradual blackening of the tip with dead tissue moving down the twig and is often observed on highly susceptible cultivars (Fig. 1). Tip die back may also occur from abiotic factors such as frost. Tip die back from frost is often accompanied by blind wood usually 6-8 inches below the tip where leaves and flowers have fallen off after being killed by a freeze.

Fig. 1 Tip die back likely bacterial spot or spring frost.

In some cases the twig may appear healthy and a shoot begins growing from the tip only to die back after leafing out and flowering. This is often a symptom of late winter/early spring infections of constriction canker. Many times a bud that was infected in the fall and never leafed out may be found just below the new shoot that is dying. This usually a good clue that constriction canker is the cause. These symptoms may be more prevalent in old trees that have a history of the disease (Fig. 2).

Tip cankers such as these may be accompanied by cankers on flower buds lower down the on the twig typically associated with blossom blight or constriction canker, or they may appear alone. Spring cankers from bacterial spot that form around flower buds are less commonly seen in our region. In cases like this it is difficult to diagnose the disease early on, especially where symptoms are randomly found at low levels or are mixed in appearance. The only thing that can be done is to note the trouble blocks and watch to see what develops. Blossom blight and constriction canker will eventually develop unique symptoms. Bacterial spot lesions will eventually show on the leaves. If you see black tip cankers forming during bloom its not a bad idea to assume its bacterial spot and include copper or oxytetracycline with your blossom blight sprays.

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!
