Fusarium wilt continues to be reported widely on watermelon. In most instances, only scattered plants are being affected in any particular field, although there have been some isolated cases where losses have been moderate to high. In at least one instance, fusarium rot has been positively diagnosed on watermelon fruit. The incidence of fusarium crown rot in tomato has also shown some increase over the past few weeks. Spider mites are increasing on tomatoes and cucurbits.
Populations are highest in driest areas along roadways and field margins.
A number of growers are reporting the highest levels in several years. Broad mites appear to be trying to make a comeback on pepper in a few locations. Persistent but sporadic, low levels of aphids have been observed in many areas on brassicas, cucurbits, pepper, potato and tomato. This situation should not lull growers into complacency. Growers need to be sure to clean up spring fields quickly.
