Rain, and overwatering of fields when plants set fruits might have contributed to the disease development. Fusarium wilt of watermelon, caused by Fusarium oxysporum f. sp. niveum, is one of the oldest described Fusarium wilt diseases and the most economically important disease of …
It is never too early to start planning for next produce season, particularly with the threat of Impatiens Necrotic Sprot Virus (INSV) looming.

Cabbage loopers and leafminers are becoming evident in some areas, and PCAs should start ramping up their monitoring and sampling. More importantly, whitely populations are quietly becoming abundant on the spring …
Two scientists have earned a place in the Agricultural Research Service (ARS) Science Hall of Fame for their pioneering and impactful research in small-fruits breeding and remote sensing for improved irrigation water scheduling. Chad E. Finn (posthumously) and William P. Kustas will be inducted in a virtual ceremony today rather than a physical event due to ongoing COVID-19 safety precautions. …
Two new races of the downy mildew pathogen (Peronospora effusa) on spinach have been denominated by the International Working Group on Peronospora in spinach (IWGP) on the basis of a worldwide evaluation of isolates from growers fields and trap nurseries.
