The Australian scientists have come up with a new technique which will enable the farmers to check the growth of disease-causing agents in soil. This will help those who grow potatoes.

The damages occurring in the potato diseases yield a loss worth $80 million every year. The potatoes are wasted in rejections.

The newly developed DNA test is capable of enumerating the disease- causing agents in the soil and see potatoes.

Dr. Kathy Ophel Keller, from the South Australian Research and Development Institute, shared that the tests will help the crop growers in assessing the soil before planting.

"It's difficult to assess the amount of disease in soil in any other way, so that the DNA testing provides a really useful decision making tool for them," he says.

However, he added that the test will not control the disease. It will simply reduce the risk associated with the agent growth and will prompt good decisions in sowing.

This technology will enhance the quality of the vegetables. The majority of the problems in the crops have been reported in the case of potatoes. The potato pathogens are the biggest problems observed, till date.
