Rhizoctonia Solani - Environment

Environment

The pathogen is known to prefer warm wet weather, and outbreaks typically occur in the early summer months Most symptoms of the pathogen do not occur until late summer and thus most farmers do not become aware of the diseased crop until harvest. A combination of environmental factors have been linked to the prevalence of the pathogen such as: presence of host plant, frequent rainfall/irrigation and increased temperatures in spring and summer. In addition, a reduction of drainage of the soil due to various techniques such as soil compaction are also known to create favorable environments for the pathogen. The pathogen is dispersed as sclerotia, and these sclerotia can travel by means of wind, water or soil movement between host plants.

Famous quotes containing the word environment:

    We learn through experience and experiencing, and no one teaches anyone anything. This is as true for the infant moving from kicking to crawling to walking as it is for the scientist with his equations. If the environment permits it, anyone can learn whatever he chooses to learn; and if the individual permits it, the environment will teach him everything it has to teach.
    Viola Spolin (b. 1911)

    For those parents from lower-class and minority communities ... [who] have had minimal experience in negotiating dominant, external institutions or have had negative and hostile contact with social service agencies, their initial approaches to the school are often overwhelming and difficult. Not only does the school feel like an alien environment with incomprehensible norms and structures, but the families often do not feel entitled to make demands or force disagreements.
    Sara Lawrence Lightfoot (20th century)

    In a land which is fully settled, most men must accept their local environment or try to change it by political means; only the exceptionally gifted or adventurous can leave to seek his fortune elsewhere. In America, on the other hand, to move on and make a fresh start somewhere else is still the normal reaction to dissatisfaction and failure.
