DENDROLOGY

Detailed explanation-1: -Crop rotation is an important consideration in disease management, particularly effective in controlling soil-and stubble-borne diseases. The goal of crop rotation is to reduce the amount of the pest population present in the soil.

Detailed explanation-2: -Cultural controls are practices that reduce pest establishment, reproduction, dispersal, and survival. For example, crop rotation-replacing a susceptible crop with a less susceptible crop; and changing irrigation practices-less watering can reduce root disease and weeds.

Detailed explanation-3: -For crop rotation to control an insect pest well, the insect must spend the period from the end of one crop to the beginning of the next in a stage with low mobility and must have a restricted range of host plants. Not many insect pests fit this pattern.
