Be Proactive, Keep Youth Safe on the Farm

How often do you say this: “do as I say, not as I do”?

The farm can be a fun, engaging, and nostalgic place to raise children; however, life on the farm comes with inherent risks that require certain precautions to make the farm a safe place for kids. The curious nature of children makes this especially difficult, as they often exhibit a lack of fear or a clear understanding of danger. According to the Children’s Safety Network, 42% of fatal injuries to youth on U.S. farms involve machinery and motor vehicles (e.g. tractors, ATVs, etc.) while another 16% of fatal injuries are due to drowning. As the school year comes to a close and your own children and grandchildren spend more time on the farm, use your actions and attitude to establish safety as a priority.

In addition to being a positive role model, make time to identify hazards around the farm and implement changes to improve safety. We have included some of these hazardous “hot spots” in the table below, along with recommendations for injury prevention.

Hazards for Children Recommendations to Prevent Injury
Workshops, chemical and grain storage areas Install gates, doors, or other locking systems to keep children out

Explain the meaning of warning signs around the farm

Clean and dispose of empty chemical containers

Establish designated safe play areas

Machinery and equipment Equipment should be turned off, disengaged, and inaccessible

Leave front end loaders and similar equipment in the down position

Lock vehicle cabs after use

Keep vehicle keys out of reach of children

Never allow children to play around machinery

Never allow children (or anyone) to be an extra rider on a tractor

Livestock Pens Only allow children to work with livestock under adult supervision

Secure livestock pens so children cannot wander into the area

 

If you’re looking for fun ways to talk with children about farm safety, check out this farm safety activity book created by the National Child Safety Council. The book includes games, puzzles, crafts, and more on a wide array of topics from livestock and tractor safety to first aid.

For more details on age-specific hazards, protective measures, and appropriate tasks for youth check out our NJAES factsheet titled “Farm Safety Tips for Children”.

Organic Production: Suppressing Soil-borne Pathogens

Pathogens such as Fusarium, Pythium, Phytophthora, Thielaviopsis and Rhizoctonia that cause pre- and post-emergent damping-off can cause serious problems in organic (and conventional) transplant production.
The key to controlling and/or suppressing damping-off pathogens with biological controls is keeping the biological populations high and continually present on root surfaces of the host, and by following good cultural practices. [Read more…]

Sweet Corn

Low numbers of European corn borer (ECB) moths continue to be captured in parts of the state.  Hot weather over the past week has not increased catches, indicating that this initial flight may be nearing its’ end.  The highest adult activity is currently Gloucester and western Burlington counties (see map at right).  Whorl corn is the primary target for egg laying, and injury as high as 18% of plants infested has been found in Hunterdon County this week.  It is typical for feeding percentages to rise as the moth catch declines.  We expect feeding to increase for the next 1-2 weeks before peaking.

Look for the characteristic “shot-hole” type of feeding (photo below at right) and consider treating when infested plants exceed 12% in a 50 plant sample.  As plantings proceed to the pre-tassel stage, ECB larvae may be found in emerging tassels (see photo at left)It is a good idea to treat individual plantings as they move into the full tassel/first silk stage one time.  This eliminates any ECB larvae that have emerged with the tassels as they begin to move down the stalk to re-enter near developing ears.

 

Useful insecticides for this particular application include synthetic pyrethroids (IRAC Grp 3), spinosyns (including OMRI approved Entrust) IRAC Grp 5), and diamides such as Coragen or Vantacor (IRAC Grp 28) or materials such as Besiege which include the active ingredient in Coragen.  Synthetic pyrethroids alone should NOT be used for corn earworm (CEW) protection on silking corn.  Control with these materials is very inconsistent.

The highest nightly trap catches of ECB for the week ending 6/09/21 are as follows:

Cinnaminson   2 Centerton   1 Green Creek   1
Downer   2 Crosswicks   1 Milford   1
Asbury   1 East Vineland   1 Oldwick   1
Califon   1 Eldora   1 Sergeantsville   1

Destroying cucurbit plantings after harvesting is a must to help mitigate downy mildew

It’s a little early in the season but now is a good time to start thinking about ways to help mitigate cucurbit downy mildew pressure later on. All cucurbit fields, especially cucumber and other summer squash fields should be destroyed immediately after the last harvest to help limit potential inoculum sources for cucurbit downy mildew, especially in later plantings.

Needs Assessment Survey for RU Ready to Farm Beginner Farm Training Program

The Rutgers Cooperative Extension Training Program-RU Ready to Farm is looking for input from beginner farmers on what types of subjects they would like to see covered. The 2022 season of RU Ready to Farm will feature in person workshops that are open to the general beginner farmer community, and the focus and content of these workshops will be designed according to community need and interest. If you have been farming for fewer than 10 years and would like to contribute to the development of this workshop series, the survey can be found here: RU Ready to Farm Needs Assessment

Basil downy mildew found in southern New Jersey – ALERT 6/8/21

Basil downy mildew has been confirmed in potted sweet basil being sold by a box-store in Cumberland County in southern New Jersey. This is the second report of BDM in the state and region this growing season. All basil growers are encouraged to scout their fields or greenhouses on a daily basis and should consider initiating a preventative fungicide program. [Read more…]
