Plant Pathology: Infection Process
... . If any of the stages of the infection process is inhibited by any of these factors, the pathogen will not cause disease in the host. While some parasites colonise the outside ... The depletion, diversion and retention of photosynthetic products by the pathogen stunts plant growth, and further reduced the plant's photosynthetic efficiency. In addition, pathogens affect water relations in the plants ...

Plant Pathology: Disease Management: Overview
... the host, the pathogen and the environment. An epidemic develops if all three of these factors are favourable to disease development. Therefore, disease can be controlled by manipulating one or more of ... . The environment can be modified so that it is suitable for plant growth but not for disease development. For example, improving soil drainage, changing the time of sowing, reducing the density of ...

Non-chemical Control of Plant Diseases in the Home Garden
... . When organisms cause disease, it is usually due to a parasitic relationship with a host plant. The parasite, or causal organism, is called a pathogen. The interaction between host and pathogen results ... months when soil temperatures are high. Frequent plowing will keep the soil dry and free of plant growth and expose soil-borne disease organisms, such as nematodes, to killing heat and excessive ...

... regulatory role of almost all known plant hormones in shade avoidance has been shown in many studies and gibberellic acid (GA) is one of the key growth factors. Recent work on the GA ... of the GA-signalling pathway. Furthermore, the stability of DELLA proteins is also affected by other plant hormones like auxin and ethylene suggesting DELLA proteins as the point of integration of different signalling ...
