INSECTS AND INSECTICIDES.

FOURTH YEAR.

(Twenty weeks, 40 minutes daily.)

The study of farm insects should include only those insects most common and most injurious to farm, orchard, and garden crops. The course is not very extensive; therefore a thorough study can be made of only a few of the more destructive insects, and from these generalizations should be made. The life history and habits of each insect should be studied and methods learned of controlling or combating it. Special emphasis should be placed on crop rotation, soil management, and time of planting as methods of control. This work should not be made too technical; just enough of life history should be taught to make sure that the student can intelligently apply methods of combating and controlling the insects.

For practical application, this work should be correlated with the farm, orchard, and garden work.
