The Australian Pesticides and Veterinary Medicines Authority (APVMA) has canceled the registration and use of all products containing chlorthal dimethyl, also known as dacthal or DCPA. Chlorthal dimethyl is a herbicide used in vegetable crops, turf, and cotton.
This is an immediate cancellation of the 12 products in Australia containing chlorthal dimethyl, no phase-out period applies. Farmers and retailers may continue to hold products until further notice but must not use them. The use of chlorthal dimethyl as an agricultural chemical product is now illegal.
The APVMA's assessment found there is an immediate risk to human health due to direct exposure:
- during mixing
- loading and applying the chemical
- from residue remaining on treated crops and turf for up to 5 days following application.
The primary risk is to unborn babies via maternal exposure. Effects may include low birth weight, impaired brain development, decreased IQ, and impaired motor skills later in life. Pregnant workers who may have concerns about exposure are advised to consult with their physician.
Information on the product recall process will be issued shortly.
