Chapter 2: Why Are Weeds So Successful? Basic Ecology Concepts
2.7 Summary
In this chapter we looked at main weed classification schemes to help with identification, as well as designing management strategies. We also talked about the importance of basing management decisions on scientifically sound experiments and data. Finally, we ended the chapter discussing some ways in which weeds negatively impact field crops.
Key Takeaways
Key takeaways from this chapter include:
- Researchers make hypotheses based on observations and use the scientific method to test their hypotheses. These findings can then be used to help producers manage their weeds on the farm.
- Ideal weed characteristics include mechanisms for long term survival, as opposed to maximum yield each year.
- Weeds can be perennials, biennials, or annuals (winter or summer) and have woody or herbaceous tissue types. Some weeds utilize C3 photosynthesis, and others C4 photosynthesis.
- Different types of interference include: competition, allelopathy, and parasitism.
