Propanil works by inhibiting the photosynthesis of weeds. Once absorbed by the weed leaves, it blocks the energy transfer process within the plant, preventing the weed from photosynthesizing properly and causing an energy supply interruption. Subsequently, the weeds gradually develop yellowing leaves, wither, and eventually die.
Primarily absorbed through the leaves of target weeds.
Weeds begin to wither within a few days of application.
Rice readily breaks down the herbicide, making it safe for rice, while weeds cannot decompose it and die.
Propanil is a selective herbicide specifically designed for controlling weeds in paddy fields, primarily for rice.
Propanil is primarily used to control annual weeds in rice paddies, with particularly significant effects on barnyard grass (Echinochloa spp.). It also effectively controls crabgrass (Digitaria spp.) and some other annual broadleaf and grassy weeds. When applied during the seedling stage, it rapidly inhibits weed growth, causing them to gradually wither and die, thus reducing competition for nutrients, water, and light from the rice.
