3-Isoxazolecarboxylic acid CAS 163520-33-0

3-Isoxazolecarboxylic acid is an herbicide and plant growth regulator used in agriculture to control a variety of grass and broadleaf weeds. It belongs to the chemical class of aryloxyphenoxypropionate herbicides. 3-Isoxazolecarboxylic acid works by inhibiting the biosynthesis of lipids in plants, leading to the disruption of cell membranes and ultimately causing the death of targeted weeds.

This herbicide is known for its selective action, targeting unwanted weeds while being safe for desirable crops when used according to label instructions. It offers effective control against various grasses and broadleaf weeds, including those resistant to other herbicides.

3-Isoxazolecarboxylic acid is typically available as a formulated product or as a pure active ingredient. It is applied as a foliar spray or through soil incorporation, depending on the target weeds and the stage of their growth. Proper dosage and application timing are essential to ensure effective weed control and minimize the impact on non-target plants.

❶ Selective herbicide: 3-Isoxazolecarboxylic acid exhibits selective action, targeting and controlling specific grass and broadleaf weeds while having minimal impact on desired crops.

❷ Wide weed control spectrum: It effectively controls a broad range of grasses and broadleaf weeds, including those that may have developed resistance to other herbicides.

❸ Mode of action: 3-Isoxazolecarboxylic acid inhibits the biosynthesis of lipids in plants, disrupting cell membranes and leading to weed death.

❹ Flexibility of application: It can be applied as a foliar spray or incorporated into the soil, allowing for different application methods depending on the target weeds and cropping systems.

❺ Compatibility: 3-Isoxazolecarboxylic acid is generally compatible with various other herbicides, allowing for tank mixing and integration into integrated weed management programs.

❻ Safety profile: When used as directed, 3-Isoxazolecarboxylic acid has been found to have a favorable safety profile for desirable crops and minimal impact on the environment.

❼ Resistance management: As a newer herbicide, it provides an additional tool for weed resistance management by offering an alternative mode of action to combat herbicide-resistant weeds.
