The soybean cyst nematode (SCN) is a very widespread, damaging soybean pest in Iowa. First discovered in north central Iowa in 1978, SCN is now thought to infest nearly 75% of fields in the state. This ISU web site contains research-based information on the biology of SCN as well as information on scouting for detection and managing SCN through use of nonhost crops and SCN-resistant soybean varieties.
Asian soybean rust was first discovered in the continental US in Louisiana in November 2004. This web site was created to present the latest information on the biology, identification, and management of Asian soybean rust, and contact information for First Detectors, a team of Iowa agribusiness personnel who serve as volunteers for the first line for rapid and accurate identification of the disease.
The cucurbit family is a medium-sized plant family, primarily found in the warmer regions of the world. It is a major family for economically important species, particularly those with edible fruits. Some of the common cucurbit food crops are watermelon, cucumber, squash, pumpkin, and muskmelon. Cucurbit crops comprise one of the most important groups of vegetable crops in the Midwest and Great Plains. 5,600 cucurbit growers plant 105,000 acres of cucurbits annually, earning $157 million. Nationally, 18,000 cucurbit growers earn $1.23 billion.
Bacterial diseases cause significant losses in many crops, and control measures are often limited or unavailable. The majority arise from invasion of the vascular system or colonization of the leaf parenchyma. The major classes of molecular tools that enable bacteria to thrive inside plants are beginning to be understood, but little is known about the functions within the plant of most of these tools. Less still is known about the plant signals and targets that render plants susceptible. Virtually nothing is known of the basis for tissue specificity.
