Preventive Measures
After visiting an infested area, ensure you get rid of plant parts and seeds from vehicles and other farming tools used. Clean pants, boots, and every other clothing used in the infested field. If domestic animals were moved through the area, ensure to check and clean their hooves/feet as well as their fleeces and coats. Cultivate only seeds that are clean and weed-free. Avoid cultivating a mixture of wildflower seeds that contains oxeye daisy. However, the following methods are effective for the Oxeye Daisy Noxious Weed Management:
Mechanical Control
The use of hoe or hand to pull out young plants and seedlings for effective control of little patches and stands. This method produces a better result if done before the dispersal of oxeye daisy seeds and flowers; preventing the seedlings from reinvading the area. Where Oxeye Daisy has greatly infested an area, repeated pulling and cutting during their growing season is highly recommended, as this will bring about a continuous reduction of the flower over the years.
Although mowing the flower will not get rid of the weed, it will restrict the seeds from further spreading if properly timed: mow as soon as flower stalks (bolts) are noticed on the plants; before flowering. You may also want to mow after a month to ensure they don’t flower again. Mowing promotes the growth of rhizomes and lateral branches and produces the best result when used together with herbicides. Mowing aids absorption of herbicide.
Cultural Control
Effective Oxeye Daisy Noxious Weed Management also entails cultivation of important plants. Perennial grasses will be very useful in this competition, especially tall species that would prevent oxeye from adequate sunlight, making it the weaker plant. If light grazing is done, this will promote the growth of grasses, keeping rangeland and pastures vigorous. Overgrazing, on the other hand, promotes the growth of Oxeye daisy, as there is weak competition. The use of goats and sheep for grazing has also produced good results over the years and gives better effect when used together with a replanting scheme and herbicide.
Biological Control
There is no known biological method for Oxeye Daisy Noxious Weed Management.
Oxeye Daisy Noxious Weed Management : Chemical Control
This is a complicated method for managing Oxeye Daisy flower. Mowing the flowers some weeks before application of herbicide may cause a more uniformed growth, enabling the larger portion of the leaves to absorb the herbicide. According to research carried out by Montana scientist, Oxeye Daisy tolerates 2,4-D at 2 Ibs per acre annually. In the southwestern part of Montana, picloram measuring about 1½ pints per acre, plus 1 quart per acre 2, 4-d was 100% effective for control of Oxeye Daisy for two years on a particular field. Unfortunately, this method is not recommended for long-term management of oxeye daisy.
Transline is another product effective for the control of Oxeye Daisy Noxious Weed Management. The recommended application is ⅓ to 1 pint/acre on young plants. Some researchers have argued that the application of fertilizers combined with herbicides with facilitate the development of the grasses and weaken the performance of oxeye daisy since the flower is not a superb competitor for nutrients.
In Eastern Washington, oxeye daisy was effectively managed with the application of nitrogen (without herbicide) at 80 lbs. per acre. Forage production recorded a 500% increase following the application of a high quantity of nitrogen fertilizer. Although there were still some traces of Oxeye Daisy, the impact was rather significant
