Usage

Description

Benalaxyl is an acylamino acid fungicide that is widely used in the agricultural industry for the control of Oomycetes on a variety of crops, fruits, flowers, ornamentals, and turf. It is known for its effectiveness in protecting plants from various fungal diseases, ensuring a healthy and productive yield.

Uses

Used in Agricultural Industry:
Benalaxyl is used as a fungicide for the control of Oomycetes on a wide range of crops, fruits, flowers, ornamentals, and turf. It helps in preventing and treating various fungal diseases, ensuring the health and productivity of the plants.
Used in Crop Protection:
Benalaxyl is used as a crop protection agent, providing a shield against Oomycetes that can cause significant damage to the plants. By controlling these pathogens, it helps in maintaining the quality and quantity of the agricultural produce.
Used in Fruit and Vegetable Production:
In the fruit and vegetable production industry, Benalaxyl is used as a fungicide to protect the plants from fungal infections. This ensures that the fruits and vegetables remain healthy and free from diseases, leading to better quality produce and higher yields.
Used in Ornamental and Turf Management:
Benalaxyl is also used in the ornamental and turf management industries to control Oomycetes and other fungal pathogens. This helps in maintaining the aesthetic appeal and health of the ornamental plants and turf, making them more resistant to diseases and environmental stressors.

Metabolic pathway

The fate of 14C-benalaxyl as affected by mancozeb is determined on the surface and in the tissues of grape leaves 7 days after the single foliar application of a mixture with mancozeb. The main oxidative scheme with rat liver microsomes is quite similar to that observed in plants. The only differences are represented by a further hydroxylation on the second ortho methyl group, and only traces of the meta hydroxylation take place on the xylene ring.

Degradation

Benalaxyl is stable in aqueous media over a wide pH range but it is hydrolysed in concentrated alkali. Its DT50 at pH 9 and 25 °C is 86 days (PM). It is reasonably stable to sunlight in aqueous solution. When irradiated in solution with UV light (254 nm) it is degraded with a half-life of 55 minutes (Pirisi et al., 1996). Products were compounds 2 and 3 (see Scheme 1) which are common also to metalaxyl and furalaxyl. These were detected in a non-labelled study. Under simulated sunlight its half-life was 167 days.
