II.Cultural Control 1.Concept of Cultural Control Deliberate modification of production practices to reduce pest population and associated crop damage. Ecological Management manipulation of the agricultural environment to reduce rates of pest population and damage. Cultural Control is called a basis of IPM

2.How cultural control tactics work: Modify crop to reduce damage Create adverse biotic conditions for pest ● Interfere with colonization of crop Enhance environment for natural enemies
2. How cultural control tactics work: • Modify crop to reduce damage • Create adverse biotic conditions for pest • Interfere with colonization of crop • Enhance environment for natural enemies
3.Cultural control approached by: 1)Fertilization and irrigation Nitrogen in particularc can affect pest reproduction over fertilization creates super- attractive insect food!! Fertility and watering can affect ability of plant to tolerate insect injury Overhead irrigation may knock pests from foliage
3. Cultural control approached by: 1) Fertilization and irrigation • Nitrogen in particular can affect pest reproduction - over fertilization creates superattractive insect food!! • Fertility and watering can affect ability of plant to tolerate insect injury • Overhead irrigation may knock pests from foliage
