Food products for chlorpyrifos will be banned, and replacement products are urgently needed in the US market

On February 25, 2022, the US EPA rejected all objections to the removal of the current maximum residue limit for chlorpyrifos, and will cancel all product registrations
related to food uses containing chlorpyrifos.
Since then, the U.
S.
EPA has sent letters to registrants of chlorpyrifos products with food uses, asking them to opt in to remove food-related uses from product labels or voluntarily eliminate food-only products
.

As of April 28, 2022, the U.
S.
EPA has received a total of 6 voluntary cancellations of 16 chlorpyrifos products containing food use (please see the table below for specific product information), and these registration certificates officially expired on August 31, 2022, and the sales, distribution and use
of the related products will also be prohibited.

Since 1965, chlorpyrifos has been widely used
as an insecticide in both agricultural and non-agricultural fields.

Chlorpyrifos is widely used in more than 60 crops such as corn, sugar beets, soybeans, onions, apples, peaches, and oranges, and chlorpyrifos is the most effective product
for reducing pest pressure on 11 crops, including sugar beets.
For example, spraying peach trunks with chlorpyrifos as well as cherry trunks before the fruit appears is effective against smaller borers
.

At the same time, chlorpyrifos is also the most effective pesticide against beetroot maggots and flies, and chlorpyrifos can be used in soybean production to control spotted leaf mites and soybean aphids that are resistant to other pesticides such as pyrethroids
.

The chart below is data on chlorpyrifos use in the U.
S.
published by the EPA in 2020, including the total acres treated by chlorpyrifos in the U.
S.
each year from 1998 to 2018 (estimated 8,000,000 acres in 2018) and total pounds of chlorpyrifos use (estimated 5,000,000 pounds in 2018).

Although chlorpyrifos has been reviewed several times since registration, chlorpyrifos is still used in large quantities in
the United States each year.
Now with the ban of chlorpyrifos food products, there is also an urgent need for pesticide products
that can replace chlorpyrifos.
In this regard, Reou suggested that relevant companies can deploy chlorpyrifos alternative products
in advance.
