Question

Answer 1

Answer:

hi

Explanation:

Crop rotation schemes work because they increase the diversity of a pest’s environment and create discontinuity in its food supply. As a rule, rotations are most likely to be practical and effective when they are used against pests that: attack annual or biennial crops have a relatively narrow host range

Answer 2

Answer:

Crop rotation schemes work because they increase the diversity of a pest’s environment and create discontinuity in its food supply. As a rule, rotations are most likely to be practical and effective when they are used against pests that: attack annual or biennial crops have a relatively narrow host range. Crop rotation is also used to control pests and diseases that can become established in the soil over time. The changing of crops in a sequence decreases the population level of pests by (1) interrupting pest life cycles and (2) interrupting pest habitat.
