Download This Lesson: Johnny Appleseed Would Be Proud
Brief Description: Students will be able to diagnose and develop an action plan for control of an apple disease using their resources. Apple diseases will be discussed and students will be able to use the internet, articles and pictures to identify the disease. Using Integrated Pest Management methods they will create outlines and visual aids to present to the class.
Focus Areas: Pest Identification and Control; Science, Computer Science, Language Arts
Focus Skills: Using the Internet to access information, reading and summarizing expository material, completing an outline, creating a visual aid, developing an action plan
Level of Involvement: AVERAGE
To diagnose and develop an action plan for control of an apple disease
What diseases threaten apple crops in the Northeast?
- How can IPM techniques be used to combat these diseases?
The use of chemical controls to combat plant diseases can be reduced by applying IPM techniques.
Read articles on pages 8, 9 and 12 in Integrated Pest Management in the Northeast Region.
Use the web site http://eap.mcgill.ca/CPAP_6.html to become familiar with apple diseases in the Northeast.
bacteria – a single celled microorganism chiefly parasitic or saprophytic
canker – a corroding or sloughing ulcer (sore) causing decay
fungus – thallophytic plants with no chlorophyll (mildew, mold, rust, smuts, mushrooms)
lesion – any morbid change in the structure of organs or parts; a hurt or injury
mildew – a thin whitish growth produced on plants and organic matter
rust – parasitic fungi causing spots or discolorations on the leaves and stems of higher plant orders
Challenge: Diagnose a given plant disease and develop a plant to combat it

Maine Learning Results
Common Core Standards for English and Mathematics
ELA – A1. Reading Interconnected Elements
A1. Students read and evaluate texts, within a grade appropriate span of text complexity, by applying their knowledge and strategies of comprehension, vocabulary, alphabetics, and fluency.
SCI – E2. Ecosystems
E2. Students describe and analyze the interactions, cycles, and factors that affect short-term and long term ecosystem stability and change.
ELA- Reading Standards for Informational Texts
2. Determine a theme or central idea of a text and analyze in detail its development over the course of the text, including how it emerges and is shaped and refined by specific details; provide an objective summary of the text.
4. Determine the meaning of words and phrases as they are used in the text, including figurative and connotative meanings; analyze the cumulative impact of specific word choices on meaning and tone (e.g., how the language evokes a sense of time and place; how it sets a formal or informal tone).
