The reason RKN is problematic lies in their ability to persist for long periods in the soil and their wide host range, which includes more than 2,000 plant species, including crops and weeds. RKN infestations are…Read more about Battling Root-knot Nematodes In Commercial Cucurbit Crops[Read More]

This week, several regions of Indiana experienced excessive rainfall due to the remnants of Hurricane Beryl passing through the state. The heavy rain caused flooding in some vegetable fields.

Figure 1 displays the varied responses of different crops…Read more about Vegetable Responses to Waterlogging Stress[Read More]
