Quash fungicide available for walnut Bot blight in California

Valent U.S.A. Corporation has announced that Quash fungicide has been registered in California for Botryosphaeria (Bot) blight control in walnuts.

First introduced in California for tree nuts and stone fruit in 2009, Quash is an effective foundation fungicide that delivers proven, broad spectrum performance for a planned rotation program.

Now, Quash also delivers preventive protection against the spread of walnut Bot blight.

Valent says the new registration for Quash provides California walnut growers with a valuable tool for producing optimal yields and improved crop quality.

The company says research on Quash shows the product is effective against the top species in the Bot blight complex for walnuts, which complements the fungicide’s long-standing preventive disease control in almonds and pistachios.

In addition to cultural practices, Quash helps to reduce pathogen populations at harvest.

In 2015 commercial walnut trials studying season-long Bot blight severity, Quash applied alone or in a rotation program effectively reduced disease incidence and development versus standard programs and the untreated check.

In 2015 University of California research, Valent says Quash applied alone in a calendar spray program effectively reduced the incidence of Bot canker and blight on current season spurs.
