Vegetable Diseases Updates:

Powdery Mildew of Cucurbits. Powdery mildew, caused by the fungus Sphaerotheca fuliginae, has been observed in all of cucurbit fields visited throughout Illinois. The disease has developed in the early growing season and it is expected to cause yield and/quality losses of the crops. Rainy weather is not necessary for development of powdery mildew. The white powdery mold first appears on lower stems and petioles. As the disease continues to develop, the white moldy spots occur on the underside of leaves. Symptoms on the upper leaf surfaces usually signal an outbreak. Based on the results of the field trials, and the results of fungicide sprays in the commercial fields, best control of powdery mildew of cucurbits has been achieved by application of Nova or Procure .
