Research suggests fumigants have very low long-term impact on soil health in potato fields

It started with curiosity. How does a fumigant, commonly used for nematode management in potato cropping systems, influence soil microbial communities? To explore this question, scientists at Colorado State University and Oregon State University used high-throughput sequencing techniques to investigate changes in soil bacterial and fungal community structure in response to the application of 1,3-Dichloropropene (1,3-D) in Pacific Northwest potato[Read More…]

Potato tuber greening: A review of redisposing factors, management and future challenges

In this scientific paper, published in the American Journal of Potato Research, scientists Sabine Tanios, Alieta Eyles, Robert Tegg, and Calum Wilson wrote that greening is a major cause of quality loss in potato tubers. As underground stems, potato tubers are non-photosynthetic plantorgans that lack photosynthetic machinery. However, after light exposure, amyloplasts convert to chloroplasts in tuber peripheralcell layers, which[Read More…]
