Asiatic Dayflower Scouting and Prevention:

This creeper plant can grow from 30 to 90 cm long, with many fleshy, thick, long leaves that are about 8 to 13 cm long and sit on the reddish stem. The creeper plant produces little (1.5cm in width) bilaterally symmetrical flowers. This means that the flower has 6 anthers that are irregular in size and 3 petals, 2 of which are deep blue and sit at the top and one lower peddle which is white. Interestingly enough, only a few flowers on a plant will open at one time and each flower only blooms for one day. The flowers are seen during the months of July to September.

Cultural Control

Restricting Asiatic Dayflower from water while adding calcium and phosphorous is a good start to controlling its aggressive nature. You can also dig out the communities of Asiatic Dayflower for several years, over time the plant will start to tire out.

Chemical Control

Asiatic Dayflower has increasingly been a threat to soybean and corn production due to their resistance to common herbicides. The herbicide to use depends on where you want to exterminate Asiatic Dayflower. If the weed has entered your soybean fields, herbicides with active ingredients of glyphosate work well.
