Paperback. Condition: New. Print on Demand. This book explores the life cycle, parasitic nature, and infectious properties of the fungus that causes the wilt disease in cotton. Discovered to reside in the soil, the fungus Neocosmospora vasinfecta enters the roots of seedlings, then spreads through the plant's water ducts, effectively cutting off the supply of nutrients and moisture the plant needs to thrive. The author provides valuable insights into the patterns of infection, sharing results from several experiments where the fungus was introduced to healthy plants through soil inoculation. These experiments revealed long incubation periods before symptoms appeared, as well as the fungus's ability to kill small roots and cause stunted growth. The author details preventive measures like crop rotation, removal of diseased plants, and proper handling of tools and manure to avoid spreading the fungus. Most importantly, the author discusses the promising results of selecting resistant cotton races for planting in infected areas, providing hope for farmers battling this devastating disease. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Paperback. Condition: New. Print on Demand. This book explores the wilt disease affecting cowpeas and root-knot caused by nematodes, examining their causes, spread, and destructive effects on crops, particularly in the Southern United States. The author analyzes the relationship of both diseases to similar afflictions in other plants, such as cotton and watermelon, and discusses the difficulties in preventing their spread. The book highlights the discovery of an iron variety of cowpea, resistant to the wilt, and explores the potential for breeding nematode-resistant strains. The significance of this discovery lies in its potential to mitigate the damage caused by these diseases and maintain the productivity of cowpea crops, a vital part of Southern agriculture and a valuable rotational crop.
