AgAlert! Herbicide Contaminated Compost

Compost has traditionally been used by growers not only for supplying nutrients to the soil and plant but also due to its multiple beneficial attributes, such as balancing pH, enhancing water holding capacity, and boosting soil structure and beneficial microbial populations to improve overall soil quality for plant growth and development. Compost can hold nutrients for a longer time and deliver to plants when needed. Nutrients found in compost are released slowly as the compost decomposes, reducing nutrient loss through prevention of off-site movement. Despite all these benefits, herbicide contaminated composts can do lots of harm to plants, especially to those belonging to the family Solanaceae, which includes tomatoes, peppers and eggplants. Plant distortion due to growth regulator type herbicide is shown in Figure 1.

AgAlert! Cucurbit Downy Mildew

Cucurbit downy mildew (CDM) has now been found in Monongalia County, West Virginia, as well as neighboring states – Virginia, Pennsylvania, Ohio and Maryland. For the latest information, visit the CDM regional map at https://cdm.ipmpipe.org/. 

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

Symptoms of the disease may vary slightly from species to species, but in general, it causes angular chlorotic lesions on the foliage. These lesions appear angular because they are bound by leaf veins. During humid conditions, the lower surface of the leaf is covered with a downy, pale gray to blackish mildew.
