Researchers with the Cornell Cooperative Extension of Suffolk County are hoping new weather stations will help local farmers better plan pest control applications, thus cutting down on chemical use on farmland.
Through grant funding, the Cornell research group’s agricultural stewardship program has installed a network of 12 weather stations across the East End so growers can better track and predict weather changes that can affect insect development, Cornell officials said.
Each station will take hourly measurements of weather factors like temperature, rainfall, wind direction and the amount of water vapor in the air. Stations will be equipped with Internet access, making the information available to growers and the public through a server at newa.cornell.edu.
Cornell will then integrate weather data with expert scouting in the field, to “predict emerging pests” and see whether pesticide applications are needed, said Rebecca Wiseman, Cornell’s agricultural stewardship coordinator.
When possible, growers can use insect traps and pheromone-based methods to disrupt mating cycles to help cut down on pest populations without using pesticides, Ms. Wiseman said. Using those techniques, she said, “pesticide use can be greatly diminished for certain kinds of pests and there are instances where it can be eliminated.”
Eleven of the 12 RainWise brand weather stations have been placed in North Fork vineyards and orchards, Ms. Wiseman said.
Before Cornell received the $190,000 in funding for the stations, which came from various organizations, only three weather stations were located on the East End, and only one on the North Fork, she said.
“The fact of the matter is, we have so many micro-climates here on the Island, the three sites were inadequate to meet the needs of our agricultural community,” she said.
Gabriella Purita, business manager at One Woman Wines and Vineyards in Southold, said the vineyard received its new weather station in May, and the device has already helped growers there with mold and mildew control.
“If we plan and see an outbreak of a certain pest, mold or mildew annually because of certain weather conditions we’ll know to preventively treat that area,” Ms. Purita said. “We hopefully won’t have to use applications because we’ll know when to use the traps and pheromone cycles when pests are at their most active.”
The better farmers can forecast weather cycles, the more they can control basic farming practices, said Joe Gergela, director of the Long Island Farm Bureau.
“It makes decision-making of farming more advanced and more economically prudent,” he said.
Aside from their potential effects on groundwater, chemicals and pesticides are expensive. Farmers do not want to use them unless they are necessary, Mr. Gergela said.
“The costs have gone up astronomically over the past five to 10 years, so it ties to profitability and good business decisions, as well as the science side,” he said.
Funding came from grants awarded by the Long Island Sound Futures Fund, the Long Island Community Foundation and the state Department of Agriculture and Markets.
