Viral disease of crops can best be controlled through
Answer Details
Viral diseases in crops are caused by viruses and can lead to significant yield losses. The most effective way to control viral diseases in crops is to prevent the viruses from infecting the crops. This can be achieved by planting resistant varieties that are not susceptible to the viruses. Resistant varieties have genes that make them immune to the viruses, so they do not get infected even when exposed to the viruses. Therefore, planting resistant varieties is the most effective way to control viral diseases in crops. Other methods like vector control, spraying insecticides, and sterilizing farm equipment are aimed at controlling the vectors or agents that spread the viruses, but they may not be as effective as planting resistant varieties.
