To select genotypes for fungal disease resistance, some artificially infected experiments would be conducted on very young (some month old) seedlings in the greenhouse. However, this fungal disease was found naturally out from the 2 year old and older plantations.
Yes, it is done all the time. It largely depends on the system. Some hosts exhibit juvenile resistance (or susceptibility) and sometimes the environmental factors make field inoculations difficult. Of course, one must also consider the quarantine implications. What fungal disease are you talking about?
Fungal diseases resistance screening done by inoculating artificially to the plants by smearing, injecting and spraying the races multiplied in the laboratory which shall be collected from naturally infected susceptible plants. After achieving the desired level of infestation for screening the test plants,chemical control measures are taken up to stop further spread of disease Then scoring for resistance should be practiced.. If disease spread is not stopped we can not get any plants for resistance, as absolute resistance is not available in the nature and also it is not desired for scientist as to safeguard the plants from evolution of new races of pathogen .
- This depends on the type of the disease, which will be doing this for artificially
I agree with Kamatar -if you dont know how to contain the disease - it will be difficult to control its spread
It depends on the pathogen and the disease. Is it a root disease? or a shoot disease? and in this case is it on leaves, twigs, branches, trunk? and which is the host?
