NJ DEP issues Controlled Open Burn Permit from April 18, through Wednesday April 22.

(TRENTON) – With the state expected to experience cooler spring temperatures, the Department of Environmental Protection has agreed with NJDA Secretary Ed Wengryn’s request to allow farmers to do controlled open burning or use specialized torches known as smudge pots to protect flowering crops from damage beginning Saturday, April 18, through Wednesday, April 22. Temperatures are expected to drop to the 30s or below this week with varying winds through portions of the state. These expected temperatures follow warm temperatures in recent days. Damage from freezing weather now can significantly reduce yields of certain fruits and vegetables that are in the flowering stage.

The DEP and the Department of Agriculture are allowing these steps to protect farmers’ livelihoods and ensure that consumers can enjoy an ample supply of Jersey produce later this year.  The DEP intends to exercise its authority and discretion under the Air Pollution Control Code, N.J.A.C. 7:27, et seq., and other applicable authorities to permit the following procedure for open burning or the use of smudge pots to assist farmers in protecting their crops in low temperatures. Farmers who believe they will need to conduct open burns and/or use smudge pots must provide notice to the DEP’s 24-hour Communications Center at 1-877- WARNDEP (1-877-927-6337). Notification to DEP does not require implementing either technique, but it ensures proper procedures are followed should they become necessary. If a farmer does not call DEP in advance but uses either technique, the farmer must notify DEP by 9 a.m. the following day. The farmer will be asked which technique was used. Farmers must record the incident number provided to them by the Communications Center. The following information is to be provided:

 Name of the individual making the decision to conduct the open burning/use of smudge pots and name of the farm.

  • Actual street address of the farm on which either technique will be used (no P.O. Boxes).
  • Telephone number of a contact at the farm.
  • Predicted temperature (in degrees Fahrenheit) at the agricultural operation when the technique will be used.
  • Wind speed anticipated when the technique will be used.
  • Predicted hours of open burning and/or use of smudge pots.
  • Materials expected to be burned.
  • At the time of the initial call to the Communications Center, farmers will be given an email address and incident number.

Within two days, they must submit to DEP via this email address the following information:

  • The DEP Communications Center incident number.
  • Ambient temperature (in degrees Fahrenheit) at the time the technique was used.
  • Actual wind speed at the orchard at the time the technique was used.
  • A statement verifying that all restrictions in the open burning or use of smudge pots were followed.
  • 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 for warming as necessary during higher wind conditions. Use of open burning when wind velocity is greater than 5 mph is strictly prohibited, may contribute to wildfire risk, and can carry significant penalties.
  • Smudge pots must be fueled only with either kerosene or No. 2 fuel oil.
  • Open burning can consist only of either the following materials: clean and untreated scrap lumber, felled trees, clippings pruned from trees and shrubs, hedgerows, or firewood. Absolutely no refuse, trade waste, tires or garbage of any type may be added to the authorized open burning material.

 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 for warming as necessary during higher wind conditions. Use of open burning when wind velocity is greater than 5 mph is strictly prohibited, may contribute to wildfire risk, and can carry significant penalties.

Recent Increase in Tomato Prices

Tomato prices in the United States have risen notably in recent months, driven by a combination of supply constraints, trade policy changes, and rising costs throughout the supply chain. Tomato prices at the consumer level nationwide, as measured by the Consumer Price Index (CPI), increased 18% from February to March and were 24% higher than a year earlier. Consistent with this trend, wholesale market data from terminal markets in New York and Philadelphia indicate strong price increases.

Note: Weekly tomato prices (non-organic) at the New York and Philadelphia Terminal Market by origin and year. Prices in 2026 are highlighted in red, while earlier years (2022–2025) are shown for comparison. Line types distinguish between origins.

 

Why Are Tomato Prices Increasing?

One of the primary drivers of higher prices is tight supply conditions. Weather disruptions in major producing regions such as Mexico and Florida have reduced available volumes, creating shortages across the supply chain.

Trade policy has also played a significant role. The imposition of tariffs on Mexican tomatoes, which account for roughly 70% of U.S. fresh tomato consumption, has increased import costs and contributed directly to higher market prices.

In addition, broader economic factors are amplifying price pressures. Rising fuel and transportation costs have increased the cost of moving perishable goods such as tomatoes, while higher input costs (e.g., energy and fertilizer) are raising production expenses, particularly for greenhouse production.
