Biological pesticide by Vestaron available to growers in Mexico

Vestaron announced Nov. 16 that its bioinsecticide, SPEAR-Lep, has been approved as the newest biological pesticide available to growers in Mexico.

The approval across international borders solidifies Vestaron’s commitment to empowering growers with novel, effective chemistries that address proven neuromuscular targets using peptides to overcome existing pesticide resistance issues. The chemistries also offer a desired safety profile for workers, bees, beneficials and the environment.

Vestaron is taking the mission of a peptide-based revolution in crop protection into Mexico with the approval SPEAR-Lep. Targeting lepidopteran pests such as caterpillars, loopers and “worms,” field trials with SPEAR-Lep demonstrate performance equivalent to conventional insecticides. With its novel mode of action (IRAC Group 32), SPEAR-Lep is a valuable new tool for IPM programs.

With an initial crop focus in crucifers, tomatoes and peppers, the Peptide emPOWERed Technology of SPEAR-Lep offers growers in Mexico the same desired benefits as in the U.S.: 0-day PHI, 4-hour REI, MRL exemption and practically non-toxic to pollinators.

“Approval of the SPEAR-Lep label in Mexico is another big win for Vestaron, allowing us to gain strides toward our mission,” Ben Cicora, SVP sales and marketing at Vestaron, said in a news release “We will bring the product to market through our Vestaron territory managers as well as partnerships with key regional distribution channel partners.”

Daniel Peck, director of field development at Vestaron, is pleased with results from the first few dozen trials completed in country.

“Field experiments with third party contractors confirm the success that we have in the U.S. Now they are being supported by larger scale demo trials in key growing regions of the country,” Peck said.
