AgAlert! Cucurbit Downy Mildew

Cucurbit downy mildew (CDM) is a destructive disease on most of the members of the gourd family or Cucurbitaceae such as cucumber, cantaloupe, pumpkin, squash, watermelon and zucchini. Cucumbers are the worst affected cucurbit that can be completely killed in two weeks from the onset of the disease.

The disease-causing organism is spread by air current from south to north during the growing season in most years. Optimum conditions for sporulation of the causal agent (Pseudoperonospora cubensis), which is an obligate parasite (an organism that can grow only as a parasite in association with its host plant and cannot be grown in artificial culture media) are 59°F with 6-12 hours of moisture present (usually in the form of morning dew or rain droplets on foliage).

CDM regional map is showing outbreak of the disease all around West Virginia, including some of the West Virginia counties, and this is the most critical time to take preventative measures against the disease.

AgAlert! Late Blight of Tomato & Potato

Late blight of tomatoes

Late blight has been detected in Jefferson County, West Virginia. This is still early in the season, and many growers may have not even harvested yet.

Considering the rainy and humid weather forecast, both organic and conventional growers should take some preventative measures.

Ag Alert! Fire Blight on Apple & Pear Trees

A close up view of fire blight on an apple tree.

2018 is a bad year for fire blight on pome fruit (apple and pear) partly due to the odd combination of bloom time, temperature and rainfall. In a regular year, most bloom occurs while temperature still below 60° F (minimum temperature required for bacterial infection through flowers).

This year it was delayed but as soon as bloom occurred temperature crossed 60° F mark and rain followed. However, WVU Extension's disease forecast-based spray schedule helped commercial growers keeping disease pressure low. The disease is more widespread at home sites.

Contact the Boone County Office for current news and to learn about upcoming opportunities in our local area. Ask us for more information about topics including:

People in Your Community…Knowledge at Your Doorstep

The Boone County Extension office provides aid to farmers, gardeners, and homeowners, but also local educational programs for area families, businesses, and communities. On our website you will find Extension Service related information on all of these subjects.  If you have questions, you can always call our office or email us.

We are also your link to other WVU Extension offices and to West Virginia University’s related colleges. WVU’s Boone County Extension Office is part of the national land-grant system. Each office has the same mission as its foundation: to help people put knowledge to work.

Each WVU Extension Office can provide the public with information on many topics from many resources. The Boone County Extension Office faculty and staff provide assistance and educational programs in the following areas: Agriculture & Natural Resources, 4-H Youth Development and Family & Community Development. To meet and support the needs of local people and communities, county faculty and staff involve local residents in developing and leading specific programs and activities.

Part of the National Cooperative Extension System

All universities engage in research and teaching, but the nation’s more than 100  land-grant colleges and universities including WVU, have another critical mission: Extension. Extension means reaching out, and along with teaching and research land-grant institutions extend their resources, solving public needs with college or university resources through local programs. With more than 3,000 county offices in the USA, the  National Cooperative Extension System is the local front door for many citizens to their state land-grant institutions.
