The main focus of our three-state (Iowa, Kentucky, and New York), three-year (2020-2022) project is on finding better ways to manage diseases, insect pests, and weeds in organic systems, and getting that information to growers. Our funding comes from USDA’s Organic Research and Extension Initiative (OREI).
Multiple days of excessive heat can be hard on vegetable crops, especially ones known to be cool-season. Brassicas, lettuce, carrots and spinach are particularly vulnerable to bitterness, wilting, bolting, deformities and coloring that affect the quality of the produce.
Many commercial growers and home gardeners often confront the issue of Blossom End Rot (BER) in their tomato, pepper, and eggplant. The BER is a physiological disorder caused by a localized calcium deficiency in the blossom-end of the fruit. It is a physiological disorder and is not caused by fungi, bacteria, or any other living disease microorganisms. Also, BER could also be seen on non-solanaceous crops such as pumpkins, squash, and watermelons.
On Monday 10 August, 2020 a devastating storm ripped past Iowa. It was unexpected and was a mighty one.Given that we are getting close to the end of the growing season does not mean that we pay less attention to plants that survived the storm. These plants are still actively growing and if properly managed could produce meaningful marketable produce.
As COVID-19 changes so many things about our society, many produce farmers are currently seeing a surge in demand for their produce from local customers. Direct marketing techniques are rapidly shifting to low- and no-contact methods. It is critical that farmers markets institute immediate changes to prevent the spread of COVID-19 among their staff, sellers and buyers.
The striped cucumber beetle is a common pest of cucurbit crops in the Midwest. The spotted cucumber beetle, also known as the southern corn rootworm, is also a pest of cucurbit crops, but the striped cucumber beetle has more economic impact due to its ability to transmit bacterial wilt.
With respect to vegetable crops, recent flooding in western Iowa has created a tough situation for growers. Given the time of the year of this catastrophic event, there were no vegetable crops standing in the field, however, water/runoff from surface waters such as rivers, lakes, or steams could have overflowed and run into fields. This water most likely could contain chemical and biological contaminants that may be harmful to the health of humans and animals.
In Iowa broccoli is typically planted early to mid-April and harvested mid-to-late June. Given the time of harvest it is often challenging to preserve the quality of broccoli in open fields. One of the major challenges growers face with broccoli is the ‘hollow stem’.
The 2018 season has ended and I wanted to share a few frequently asked questions, problems, concerns, and trends that I am seeing. Rather than waiting until next year to address these issues, it seems easier to do so while the year is still fresh in our minds.
As the season winds down for summer crops (sweet corn, pepper, tomato, etc.) we should not let our guard down on fall crops such as broccoli, cabbage, brussels sprout, kale, etc. These crops are on still actively growing and need attention when it comes to pest management.
