Dow AgroSciences gets OK to market fungicide for bacterial spot in tomatoes

Dow AgroSciences recently announced that the label for its Quintec fungicide has been expanded to include bacterial spot in tomatoes, which can destroy tomato seedlings and lead to total crop loss if untreated.

Quintec, which is already used by many growers to manage bacterial spot in peppers and powdery mildew in cucurbits, is now approved in most states for application on tomatoes.

Dow AgroSciences Field Scientist Alejandro Calixto said that growers are running out of options to manage bacterial spot because of copper resistance.

“Quintec provides suppression of bacterial spot, and, most importantly, the product gives tomato growers a much-needed tool to manage bacterial spot in their fields,” Calixto said.

With its unique mode of action, Quintec is ideal to rotate with copper and mancozeb. Quintec can be tank-mixed with most insecticides, but the company does not recommend adding crop oil or tank-mixing Quintec with micronutrients. Quintec has been field-tested for more than four years on more than 12 different varieties of tomatoes.

Bacterial spot can be destructive to tomato seedlings and can lead to total crop loss if untreated. Severe damage to enlarging fruit renders them unmarketable due to poor quality.
