AgAlert! Threat of Corn Ear Mold in West Virginia

Above average rainfall and continued wet weather has slowed field corn dry-down and delayed harvest across the state this fall.

This situation has created several problems, including encouraging the growth of corn ear mold and reducing grain quality. In some cases, these types of mold may also pose a risk of mycotoxin contamination of the kernels, depending on what type of fungal growth dominates, and thereby, affecting the overall grade of the corn.

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.
