Vegetable Disease Update – 5/25/15
Pepper
Bacterial leaf spot – Symptoms of bacterial leaf spot on pepper leaves include small, brown water-soaked lesions that turn brown and necrotic in the centers. Spots may coalesce and form large blighted areas on leaves and premature defoliation can occur. On fruit, brown lesions can form which have a roughened, cracked wart-like appearance. High temperatures, high relative humidity and rainfall favor Bacterial spot development. Loss from Bacterial spot can be reduced somewhat by maintaining high levels of fertility, which will stimulate new growth. Applying a fixed copper (M1) at labeled rates or may help suppress spread. Quintec (quinoxyfen, 13) at 6.0 fl. oz/A is now labeled for the suppression of bacterial leaf spot in pepper in the mid-Atlantic region. Please see the 2015 New Jersey Commercial Vegetable Production Recommendations Guide for more information. [Read more…]

Most early sweet corn plantings are too young to support ECB larval infestations. However, over the next two weeks we should begin to see feeding in the most advanced plantings. Be sure to begin monitoring the earliest plantings for ECB feeding while they are still in the whorl stage. For detailed information see:
| The highest nightly ECB catches for the previous week are as follows: | ||
| Belvidere 2 | Allamuchy 1 | Port Colden 1 |
| Blairstown 2 | Califon 1 | Sergeantsville 1 |
| Denville 2 | Centerton 1 | Tabernacle 1 |
| Medford 2 | Pedricktown 1 | Woodstown 1 |
