Mary Hausbeck from Michigan State University will present Downy Mildew Management in Pickling Cucumbers on Tuesday at 09:00 AM.
Changes in Winter Squash Fruit Exocarp Structure Associated with Age-Related Resistance to Phytophthora capsici by Safa A. Alzohairy, Ray Hammerschmidt, and Mary K. Hausbeck Published Online:27 Aug 2019 Phytophthora capsici is a destructive pathogen of cucurbits causing root, crown, and fruit rot. Winter squash (Cucurbita sp.) production is limited by this pathogen in Michigan and other U.S. growing […]
“Downy mildew on cucumber has been verified in three cucumber producing counties on the west side of Michigan and one pickling cucumber producing county on the east side of Michigan.” “Cantaloupe crops are also at risk of becoming infected by downy mildew and should be protected using the fungicides that have been proven to be […]
Downy mildew on cucumber has developed in a small research plot at the Southwest Research and Extension Center in Benton Harbor, Michigan. This is the first confirmed report in Michigan in 2019. Disease symptoms developed over the last several days and this research plot had not been sprayed with any fungicides. Continue Reading
This plant pathogen lives in the soil and survives Michigan winters. It does not move via air currents but spreads via splash of contaminated soil, surface water such as culverts, rivers, creeks and streams contaminated by run-off from infested fields, and the dumping of diseased culls onto production fields. Phytophthora is especially unique because it can develop […]
Downy mildew on cucumber or any other cucurbit has not been confirmed yet in 2019 in Michigan or in adjacent states of the Great Lakes region. Our molecular analysis of the spore traps has recently confirmed cucumber downy mildew spores in the air via our molecular testing a couple of times, but this has not […]
Act now to protect cucumbers from downy mildew. The Hausbeck vegetable pathology lab at Michigan State University has established a network of spore traps in major cucumber production areas of their state. This year, they have the ability to distinguish the spores of cucumber downy mildew from the spores of hop downy mildew . The spores […]
Cloudy, humid and wet weather are perfect conditions for downy mildew. These conditions also favor the transport of downy mildew sporangia into our Michigan growing areas. Continue Reading
