Bacterial wilt of Cantaloupe

Figure 1: The wilted and collapsed area on the margin of this leaf is due to bacterial wilt of cantaloupe. Note also the areas of the leaf eaten by cucumber beetles.

Figure 2: Cucumber beetles have eaten this cantaloupe leaf. If insect frass enters the eaten area, bacterial wilt may result.

Figure 3: Quick field test for possible bacterial wilt. Stringy, viscous sap may indicate presence of E. tracheiphila, causal pathogen of bacterial wilt.

Figure 4: General wilt of cantaloupe caused by bacterial wilt.
