The following points highlight the top four techniques for detection of seed borne viruses. The techniques are: 1. Dry Examination 2. Biological Methods 3. Biochemical Method 4. Serological Methods. Technique # 1. Dry Examination: A close inspection of the see may give an indication of the presence of virus in certain seed. Phatak (1974) found that in 13 genera no [...]
In this article we will discuss about the management of soil borne diseases. Plant diseases result when a susceptible host and a disease-causing pathogen meet in a favorable environment. If any one of these three conditions were not met, there would be no disease. In contrast, the threat of disease epidemics in crop production is constant. Microorganisms are important component [...]
The following points highlight the five ways for management of soil borne diseases. The ways are: 1. Mycorrhizal Fungi 2. Crop Rotation 3. Plant Nutrients 4. Compost 5. Direct Inoculation with Beneficial Organisms. Way # 1. Mycorrhizal Fungi: Among the most beneficial root-inhabiting organisms, mycorrhizal fungi can cover plant roots, forming what is known as a fungal mat. The mycorrhizal [...]
