Doctoral student Ching-Jung Lin of the laboratory of nematologist Shahid Siddique, associate professor, UC Davis Department of Entomology and Nematology, is the recipient of a two-year, $32,000 Ministry of Education Taiwan Government Scholarship to Study Abroad (GSSA).
The scholarships are awarded to young Taiwanese doctoral students in various fields to support their research.
Lin enrolled in the UC Davis plant pathology doctoral program, with a designated emphasis in biotechnology, in 2020. In the Siddique lab, she is working on nematode transformation and nematode-induced plant immunity.
Lin received her bachelor's degree in...

Pathogen native to U.S. but had not infected pines until recently
Fungal pathogens that cause die-back in grape, avocado, citrus, nut and other crops has found a new host and is infecting conifer trees causing pine ghost canker in urban forest areas of Southern California.
The canker can be deadly to trees.
Scientists from University of California, Davis, first spotted evidence that the pathogens had moved to pines during a routine examination of trees in Orange County. Over four years, they found that more than 30 mature pines had been infected in an area of nearly 100 acres, according to a

¿Está preocupado por un síntoma de enfermedad en su campo pero no sabe cuál es?
¿Necesita ayuda para diagnosticar un síntoma?
¿Por qué es importante tener una identificación adecuada de las enfermedades de las plantas?
Sin una identificación adecuada, los esfuerzos de control de enfermedades pueden ser una pérdida de tiempo y dinero si se adopta un enfoque incorrecto. La implementación de medidas de control de enfermedades que no son adecuadas para manejar el agente causante de la enfermedad podría provocar más pérdidas de plantas. Las enfermedades de las plantas son causadas...

Are you concerned with a disease symptom in your field but do not know what it is?
Do you need assistance diagnosing a symptom?
Why is it Important to have Proper Identification of Plant Diseases?
Without proper identification, disease control efforts can be a waste of time and money if an incorrect approach is taken. Deploying disease control measures that are not suitable to manage the disease-causing agent could lead to further plant losses. Plant diseases are caused by infectious parasites such as nematodes, fungi, oomycetes, viruses, and bacteria. Various symptoms can be caused by a wide variety of organisms (Figure 1), because of this, proper identification of a pathogen is...

SUMMARY
- Two broccoli plantings immediately prior to growing the verticillium-susceptible crop is recommended for best protection
- Fresh broccoli residue has greater reduction in V. wilt than dry residue
- Field tarping following fresh residue incorporation did not increase (or decrease) efficacy
- Suppression of V. dahliae is specific to broccoli and not provided by other Brassicaceae crops.
- V. dahliae isolates from 15 host crops, including tomato, eggplant, bell pepper, lettuce, potato, watermelon and strawberry, were effectively suppressed by 5 broccoli cultivars
- The most significant reduction in V. dahliae occurs 15 days post-incorporation, and...
