In Vitro Imazethapyr belongs to the imidazolinones family of herbicides that are being extensively used in a wide range of cropping systems to enhance crop yields and protect crops from damage by weeds and annual grasses in soybean and peanut. Imazethapyr would affect the transcription of photosynthesis-related genes and inhibit the antioxidant system of the plants and affect the chlorophyll synthesis[2].
