Pre-Infectional Processes

Explain the pre-infectional processes used by plants in defense against plant pathogenic attack. Describe the cultural methods that can be used for managing plant disease. Differentiate between conducive and suppressive soils. Explain the different types of genetic resistance of plants. Answer Pre-infectional processes used by plants Though, there are many pathogens (disease causing agents) which attack on plants yet, plants try their best to resist them via adoption of pre-infectional procedures. Such as development of cuticle, secretion of anti-microbial enzymes or other chemicals may be kept in this category. Cultural methods for managing Plant diseases Plant diseases may also be tackled via specific cultural techniques such as Selection of resistant variety. Destruction of residual plant material as it may serve as food for plant pathogens. Elimination of pathogens infected plants, so that they could not spread the disease in other plants Crop rotation because, it might resist the development of pathogens which depend on a particular crop variety. Conducive and Suppressive soils Conducive soils This soil might be easily attacked by pathogens due to their favorable growth conditions or absence of invasive microbes enemies. Suppressive soils This is the soil that can resist growth of pathogens due to its resistant
