Organic Farm Advisory

The Plant & Pest Advisory serves NJ growers by reporting on important pests and recommending responses that are grounded in reproducible trials.

Articles in this section contain information helpful to the NJ commercial organic grower.

Sharing organic practice trial results between land-grant universities is a cost effective way to create a common knowledge base built on the strengths of individual programs. In the sidebar, find institutions with programs in organic agriculture which augment knowledge developed at the Rutgers New Jersey Ag Experiment Station.

Rutgers Cooperative Extension Field Guides: These concise guides help with decision making from pre-planting to harvest. For each crop listed, learn what pests to proactively look for as the season progresses, how to look for them, and when to take action.

Beat the Heat: Water and Sports Drinks for Hydration

Article By: The Rutgers Farm Health and Safety Working Group: Kate Brown, Michelle Infante-Casella, Stephen Komar and William Bamka

When it comes to hydration, the U.S. National Academies of Sciences, Engineering, and Medicine recommends an adequate daily fluid intake of about 15.5 cups (3.7 liters) of fluids a day for men and about 11.5 cups (2.7 liters) of fluids a day for women. Even with this guidance, the amount varies from person to person. Also, when temperatures are hotter and when workloads increase so should drinking water, to prevent dehydration and to help maintain the proper body temperature especially when sweating.

Regular intake of water throughout the day and during the evening, at recommended amounts may help prevent a person from becoming excessively thirsty and also prevent dehydration. The choice of drinking sports drinks that contain electrolytes may be considered when a person’s activities dramatically increase, when they excessively sweat, if they show signs of dehydration, and/or heat stress.

Most sports drinks are designed to replenish glucose, fluids, and electrolytes (sodium, potassium, magnesium, calcium) lost during strenuous exercise or heavy workloads. Sports drinks may contain carbohydrates in the form of sugar, usually glucose, high-fructose corn syrup, or sucrose. Some contain no sugar and are “sweetened” instead with low-calorie sweeteners. The amounts of sugar and electrolytes in sports drinks are intended to allow for quick hydration and absorption.

It is important to note, persons with diabetes should be mindful of not intaking amounts of sports drinks that are high in sugar that could raise blood sugar to unhealthy levels. Additionally, persons with high blood pressure should be mindful when drinking sports drinks that are high in sodium – most are. Persons who eat a healthy diet should have enough glucose and electrolytes to maintain their health, even during extra activities and with proper water intake. Some studies show drinking too many sports drinks, especially when not performing vigorous exercise, can increase the risk of overweight/obesity and other health issues such as type 2 diabetes, cardiovascular disease, gout and the risk of dental cavities.

Water is the best choice to stay hydrated and it is the responsibility of each individual person to be sure they drink enough water to maintain their proper health.

Vegetable IPM Update 6/12/24

Sweet Corn

European corn borer (ECB) moths continue to be captured in blacklight traps in the northern and central counties, with highest moth activity in Middlesex, Somerset and lower Hunterdon counties.  The highest feeding levels are in Somerset and southern Hunterdon Counties.   ECB injury over 20% of plants infested has been found in that area recently.  While ECB has become something of a local phenomenon in NJ, growers should not assume that feeding is below economic levels in their area.   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 6/12/24 are as follows:

Bellemeade   3 Denville   1 Milford   1
South Branch   2 Georgetown   1 Oldwick   1
Asbury   1 Hillsborough   1 Pennington   1
Dayton   1 Lawrenceville   1 Sergeantsville   1

Preparing for basil downy mildew in the field in 2024

For over a decade, basil downy mildew (BDM) has caused significant losses in basil grown in organic and conventional field and greenhouse production across the United States. At the time of its introduction, there were very few fungicides labeled for its control making it nearly impossible to grow a successful crop in many areas of the country. [Read more…]

Sweet Corn

European corn borer (ECB) moth captures are fairly steady at low levels in northern and central county light traps.  Feeding has been detected in some whorl and pretassel stage plantings where scouting is occurring.  Thus far, feeding has been mostly in single digit percentages, although one planting in Somerset County approached 20% plants infested.  Feeding may be expected to rise modestly over the next two weeks.  Whorl corn is the primary target for egg laying.  Feeding may be present  at higher numbers in the southern counties.

Sweet Corn

European corn borer (ECB) moth captures have increased in northern and central county light traps.  Numbers are low, as they have been in recent years, and no feeding has been detected on whorl and pre-tassel stage sweet corn as far south as northern Burlington County.  Whorl corn is the primary target for egg laying.  If the peak of the first flight is late, it sometimes results in heavier infestations on 2nd and 3rd plantings than on the first.  Feeding may be present in the southern counties, and should rise over the next 3 weeks.

Grape and Wine Science Certificate Program

Grape and Wine Science Certificate Program will be offered July 22-Aug 16, 2024. This program will provide foundational knowledge in three major areas of grape and wine science – grape growing, wine making, and business operations – following the path of grapes from the field to the winery to the glass. Students will gain competency in all three areas to prepare them for positions in the industry. The program will feature 4 weeks of classroom instruction, complemented by hands-on workshops. Then students will complete a 4-week winery internship where they can put their new knowledge and skills into practice. [Read more…]
