Weed Management Final Exam
3 Stages to Prevent Weeds - ANS-Prevent Arrival
Prevent Establishment
Prevent Spread
Approach to aquatic manage - ANS-Identify invasive plant;
Determine the way it was delivered - prevent re-introductions;
Identify desired flora;
Evaluate environment, watershed, and value for lengthy-time period plan;
Use BMP and IWM;
Educate nearby managers and public;
Assess the results.
Best Management Practices to Reduce Herbicide Resistant Weeds - ANS-Use more than one
herbicide mechanisms of action;
Use various method, attention on preventing seed manufacturing
Plant into and keep fields weed unfastened
Plant weed free seed
Scout fields automatically;
Biological Control - ANS-Introduction of weeds herbal enemies.
Very species precise -vital!
Unable to breed on vegetation aside from their weedy hosts.
Won't damage applicable plants/non goal species.
Characteristics of Invasive aquatic plants - ANS-Nearly all introduced - in large part spread via
human beings (water garden, aquarium industry, boats)
Requires "average" nutrient concentrations
Chemical Control - ANS-Floating and emergent flora:
Apply herbicide direct to the foliage.
Very much like terrestrial weeds.
Root uptake from water viable.
Submersed flowers: More difficult and high-priced.
Treat the water (ppm and ppb).
Conditions that Encourage Resistance - ANS-Frequent use of herbicides with comparable mode
of motion
Weed control systems that rely normally on herbicides for weed control
Lack of non-chemical weed manipulate practices.
