Integrated Pest Management

Integrated pest management is the application of two or more management alternatives that are complimentary in weed suppression, increase the longevity of control procedures, and improve crop production or conservation of resources. The integration of multiple management practices should be designed based on the stage of oxeye daisy invasion.

On populations in the early phase of invasion, aggressive herbicidal or hand control should be combined with cultural practices that strengthen the competitiveness of the plant community including the application of 80 lbs./acre nitrogen on non-native pastures and haylands. In areas with large-scale infestations in the later phases of invasion, first priority should be given to herbicide application to eradicate small, satellite populations and to reduce spread along the invasion front of the parent population.

Second priority should be given to reducing the parent population using herbicide management, nitrogen addition to grass communities, and re-vegetation with competitive plants where needed. On grazing lands, prescribed grazing management using multiple species should be timed to maintain the vigor of rangeland plants and prevent oxeye daisy seed spread. On crop and hay land in rotation, tillage combined with herbicide treatment will be more effective than either of the treatments applied alone, and a nutrient management plan should be followed. On disturbed sites, pastures, and rangeland where competitive plants have been lost, re-vegetation following control of oxeye daisy will improve the longevity of the control application.
