Tăierea reziduurilor de pulverizare cu pesticide pe culturi Scopul acordării, cercetare

Reducerea utilizării pesticidelor cu spectru larg care lasă reziduuri pe alimente marchează punctul central al unui nou proiect de cercetare condus de Lav Khot., un profesor asistent la Departamentul de Inginerie a Sistemelor Biologice de la Universitatea de Stat din Washington.

Efforts by Khot and his cohorts will be funded through a 3‑year, $300,000 New Investigator grant from the Foundation for Food and Agriculture Research (FFAR).

WSU professor Lav Khot prepares flying an 8‑bladed octo‑copter over a vineyard to measure the irrigation effectiveness.

Part of the grant will be used to study the usefulness of ozonated water, or water that has the O₃ moleculă, also known as ozone, dissolved into it.

"În laborator, we’ll look at how efficient we are in effectively delivering ozonated water as spray to control insects and other pests,” said Khot, the principal investigator on the grant. “The challenge is to deliver the required concentration at the point‑of‑contact. If we’re successful, then we’ll apply the sprays in a limited manner with the goal of reducing chemical residues on the produce.”

Khot said some commercial companies are advertising new ozonated water sprayers that have made promising claims regarding pest and disease control outcomes in orchard crops. Growers want independent data and validation before making a significant investment into these technologies.

Khot and his team also will look at emerging technologies to study new organic products like plant extracts and highly refined petroleum oils. They will test application using smart sprayers to study their effectiveness in pest control, Khot said.

“There’s a lot of interest in these oils,” said Khot. “They’ve been very efficient in fighting citrus greening disease in Florida, and we want to see if they can be used in Washington agriculture.”
