Benalaxyl is the International Organization for Standardization (ISO) approved name for methyl N-(2,6-dimethylphenyl)-N-(phenylacetyl)-DL-alaninate, which is a broad-spectrum, phenylamide fungicide with protective, curative and eradication action. It inhibits mycelial growth of fungi and germination of zoospores. It has a low aqueous solubility and is quite volatile.
Some synonyms of benalaxyl include:
- Benalaxyl, (D)-isomer
- Benalaxyl, (L)-isomer
- Galben
- Caswell No. 471AC
- EINECS 275-728-7
- Farmoplant
Benalaxyl has a molecular formula of C20H23NO3.
List of known side effects
Benalaxyl is highly toxic to aquatic organisms with long lasting effects, as noted in the PubChem online database. Additionally, it is toxic to honey bees, earthworms and wild bird species.
However, it is not a known eye irritant or skin sensitizer. There were no significant symptoms of intoxication in the studies of oral and dermal exposure with animal models. The test animals showed normal behavior and exhibited normal conditions after 24 hours since testing. There were no deaths or clinical signs of toxicity, but the doses showed to at least affect liver weight.
Studies of metabolism in rats confirm that benalaxyl is rapidly excreted via urine and feces and extensively metabolized.
Body systems affected by benalaxyl
Benalaxyl is categorized as a Class U toxin – unlikely to cause hazard, according to The Pesticide Encyclopedia by Vasant Gowarikar, V. N. Krishnamurthy and Kalyani Paranjape. Additionally, there was no evidence of any carcinogenic potential of benalaxyl based on animal tests on mice.
Items that can contain benalaxyl
Benalaxyl is applied to a wide variety of fruit and vegetable commodities to control fungal infections such as downy mildew, powdery mildew, late blight and gray mold. Some of these crops include (but not limited to):
- Cucurbits such as melons and watermelons;
- Roots and tubers like potatoes, horseradish, taro, yam, sweet potato, sugar beets, turnips, carrots and ginger;
- Bulb vegetables like onions, garlic, leeks and shallots;
- Leafy greens like watercress, kale, lettuce, cabbage and Brussels sprouts;
- Cereal grains such as brown rice, wheat, barley, rye and buckwheat; and
- Legumes and pulses like peas, soybeans and kidney beans.
How to avoid benalaxyl
Benalaxyl is a common fungicide used to control fungal pathogens on a number of crops. Avoid fruits and vegetables that are usually sprayed with this chemical, such as grapes, potatoes and tomatoes.
Moreover, avoid products that use benalaxyl as an active ingedient, such as Kiralaxyl, manufactured and supplied by Isagro, as noted in an entry by the Pesticide Properties DataBase.
