Pineapple nematode research in hawaii: past, present, and future.

Movement of bromacil in a Hawaii soil under pineapple cultivation - a field study.

Recent discovery of low concentrations of bromacil in drinking water prompted the State of Hawaii to examine the leaching behavior of bromacil in pineapple fields. This study is a follow up to earlier work on bromacil concentrations in soil profiles in a pineapple field in central Oahu, Hawaii. Soil samples were collected for bromacil analysis at different times prior to and after application f...

Interactions Between Rotylenchus reniformis and Pineapple mealybug wilt associated virus-1 in Pineapple
