COURSE OBJECTIVES/GOALS
The objective of this course is to give students a fundamental and practical understanding of the
field of weed science as related to agronomic crop production in North Carolina. Students will gain
an appreciation for weed ecology and identification; appropriate methods of weed control in corn,
cotton, peanuts, small grains, soybean, and tobacco; basic concepts of herbicide behavior in soils
and plants; application technology; and principles involved in developing successful weed management strategies.
LECTURE SCHEDULE
The following topics will be discussed in the order listed below:
- Introduction to weed science

GRADING
Grading Scheme: Final letter grades will be based on daily quizzes (200
points), three one-hour exams (300 points), lab grade (200 points), and a final
exam (100 points). Final grades will
be determined according to the following scale. The + or - grading system will be
used.
A+ 95-100
C+ 76-78

Grades may be adjusted up
if necessary so that the class average approaches a C (approximately 74%).
ABSENCES
Quizzes are given at the beginning of each class. You are allowed to drop three quiz grades. Quizzes may not be made up. Absence will result in a zero for the day except with prior approved permission or in the event of a properly documented medical or family emergency. Attendance is necessary to perform well in this class because 25% of the final grade is based on daily quizzes.
Attendance is essential to performing well in this class.
For a complete explanation of the University Attendance policy, students should refer to the web site http://www.ncsu.edu/policies/academic_affairs/pols_regs/REG205.00.4.php .
LAB SCHEDULE
The lab portion of CS 052 will meet from 1:30-3:20 pm – Thursday in 1403 Williams.
Daily tests will be given in the lab section.
The following topics will be discussed
Weed identification
Sprayer calibration
Spray equipment and technology
Herbicide labels ACADEMIC INTEGRITY
Scholarly activity is marked by honesty, fairness and rigor. A scholar does not take credit for the work of others, does not take unfair advantage of others and does not perform acts which frustrate the scholarly efforts of others. A scholar does not tolerate dishonesty in others. The violation of any of these principles is academic dishonesty.
Academic dishonesty includes the giving, taking or presenting of information or material by a student with the intent of unethically or fraudulently aiding oneself or another person on any work which is to be considered in the determination of a grade or the completion of academic requirements. More specific definitions are set in the NCSU Code of Student Conduct.
The students and faculty of NCSU believe that the willingness of students to affirm and adhere to the essential values of honesty and integrity in all their academic endeavors is exemplified in the Honor Pledge:
I have neither given nor received unauthorized aid on this test or assignment.
You should be familiar with the University’s policy on academic integrity found in the Code of Student Conduct and Honor Pledge described in the brochure on Academic Integrity at NCSU. This information can be obtained from the Department of Student Development located in Harris Hall. The content included in these documents applies to this course. Your signature on a test or assignment means that you have neither given nor received unauthorized aid and represents your commitment to honorable and trustworthy behavior that is in the spirit of the Honor Pledge. It is permissible for you to share class notes and study in groups.
A grade of zero will be assigned to an examination, quiz, or assignment for which there is evidence of cheating.DISABILITY SERVICES FOR STUDENTS (DSS)
Reasonable accommodations will be made for students with verifiable disabilities. In order to take advantage of available accommodations, students must register with Disability Services for Students at 1900 Student Health Center, Campus Box 7509, 515-7653. www.ncsu.edu/provost/offices/affirm_action/dss/ For more information on NC State's policy on working with students with disabilities, please see www.ncsu.edu/provost/hat/current/appendix/appen_k.htmlSTATEMENT ON LABORATORY SAFETY
All students are expected to exercise proper safety precautions in the laboratory. Safety guidelines will be reviewed during the first lab period, and as required during the semester.STATEMENT ON PASS THROUGH CHARGES
Students are responsible for field trip fees.STUDENT CONDUCT
The NCSU Code of Student Conduct describes the kind of student behavior that disrupts and inhibits the normal functioning of the University and the actions that the University will take to protect the community from such disruption. It is your duty as a member of the University community to read, understand, and adhere to the Code of Student Conduct. It is contained in the NCSU Handbook for Teaching and Advising as Appendix L. The Crop Science Department at North Carolina State University is committed to providing all students with an educational experience and background that will serve as a platform for success in future professional and personal endeavors. A learning environment that fosters professionalism is central to accomplishing these objectives. For this reason, activities such asdrinking, eating, sleeping, tobacco chewing, smoking, or reading of non-class materials or any other activities that are disruptive to the classroom or laboratory learning environment will not be tolerated. You can be asked to leave class if these rules are violated. In addition, it is important to recognize that the equipment and classroom facilities used in our teaching endeavors are the property of the tax payers of North Carolina and as such, and will be treated with respect.
