| Soybeans Under Attack – Cotton Leafworm June 23, 2022 On June 5, 2022, a partner in Sakha, Egypt, noted feeding damage in their soybean field 15 days after planting and alerted the SIL Disease and Pest Team (DPT). The soybeans were in the second vegetative stage (V2), so still young small plants. The feeding occurred between the leaves veins and was circular and irregularly shaped with rough edges. Droppings were present on the leaves, and younger worms were only scratching the leaf surface, leaving a white film in some cases.  Collegues in Egypt identified the pest as the cotton leafworm and sprayed the field with insecticides containing Chlorfluazuron for control. The cotton leafwork had migrated from nearby cotton fields and demonstrates that pests from other crops can feed on soybean. When newly introduced or rotated in, soybean may serve as an opportunistic food source for insects, such as occurred here in this traditional cotton region. To help keep your soybeans healthy, the DPT created the Disease and Pest ID Board Facebook page and a Whatsapp group to help soybean producers keep abreast of pests and disease in their area, share photos and treatments, and seek and receive technical support and solutions.

Together, we are stronger for soybean success! |
