​ On August 12, 2015, USDA designated 88 counties in Indiana as natural disaster areas due to heavy rainfall since May. The four counties not designated disaster areas are LaGrange, Perry, Spencer and Steuben. Farm operators in the ‘disaster’ counties are eligible for low interest emergency loans from the Farm Service Agency, provided they meet certain qualifications and eligibility requirements. Farmers have eight months, or until April 12, 2016, to apply for the loans. Contact your local USDA Service Center  for more information about loans and to learn about additional programs available to help recover from disaster, or visit http://disaster.fsa.usda.gov. ​ Source: USDA Office of Communications http://content.govdelivery.com/accounts/USDAOC/bulletins/11421cf​​


​​Code Red Webinar. Thursday, August 27, 2015. 12:00 P.M. – 1:00 P.M. EDT. The Code Red tool developed by the Purdue Women in Agriculture Team is a must have for every family, business, and farm operation. The tool includes important information such as passwords, bank account information, rental agreements, insurance papers, power of attorney documents, and much more, in one easy location. After completing the Code Red plan, it will become the “go to” tool if something happens to a key member of the management team. We hope this tool will help farm families turn a code red situation into a code green so the business can continue to operate on a daily basis. To participate, register at https://goo.gl/f3gLFM. You will then receive a confirmation email with the link to participate in the webinar August 27. You will also receive a reminder 24 hours before the webinar begins.

Vegetables such as this watermelon may become sunburned if lack of foliage cover exposes the fruit to excess sun and heat. (Photo by Dan Egel)

​Loss of foliage due to poor growing conditions or disease can cause fruit to be exposed to the sun. Hot temperatures and direct sunlight can lead to areas of the fruit that appear bleached or sunburned. Sunburned fruit may not be marketable. To reduce the probability sunburned fruit, every effort should be made to maintain foliage throughout the season. Early wet weather encouraged foliar disease and recent hot, dry weather may have restricted foliar development. Orienting vegetable plantings to minimize damage from the prevailing winds and providing windbreaks such as strips of rye or wheat may help to reduce sunburn. Several products are available that are labeled for use as a preventive for sunburn. These products may be broken into two groups: kaolin (clay) based products and calcium carbonated based products. Kaolin based products include Surround®. Some Surround® products are labeled for use as sunburn protection, while others are not. For example,[Read More…]


Magnesium deficiency in cantaloupe often occurs in high

​I have observed many fields of cantaloupes with magnesium deficiency or manganese toxicity. Watermelon plants may exhibit similar symptoms, but not as frequently as cantaloupe. Both disorders are related to acid (low pH) soils and usually occur in clusters in a field. Magnesium deficiency usually appears on sandy ridges and can be recognized by interveinal yellowing and death of tissues on older leaves (Figure 1). Manganese toxicity also first occurs on older leaves but appears in heavier or darker sands, often in low areas of the field. The diagnostic feature of manganese toxicity are the tiny pin-hole type lesions with yellow halos clustered between the veins (Figure 2). Leaves are best viewed when held up to the sun. These disorders can easily be confused with an infectious disease. In particular, magnesium deficiency has been confused with Alternaria leaf blight. Symptoms may seem to “spread” from areas of the lowest pH[Read More…]

​Growers may be wondering whether to replant pumpkin fields where the stand is uneven due to excess moisture. Potential yield of the replants is one thing it would be good to know. We have data on yield of pumpkins direct-seeded or transplanted in mid-July in northern Indiana. The trials were no-till planted into a harvested wheat field. Pumpkins were harvested in mid to late October. Yield of direct-seeded pumpkins ranged from 0 to 0.6 tons per acre for 8 varieties in 2004, and from 2.6 to 6.4 tons per acre for 5 varieties in 2005. Yield of transplanted pumpkins ranged from 2 to 8 tons per acre for 8 varieties in 2004 and from 4.4 to 9 tons per acre for 5 varieties in 2005. For comparison, typical yields at this site for an early- to mid-June planting date with conventional tillage range from 10 to 25 tons per acre.[Read More…]


​The Agricultural Marketing Service (AMS) at USDA publishes information about prices, supplies, movement, and quality of vegetables every business day. On Thursday, July 16, 2015, 2:00 to 3:00 p.m. Eastern Time, AMS will offer a webinar about the Fruit & Vegetable Market News, what information on organic crops is available, and how to use the Market News Portal. There is no cost, but participants should register in advance at http://bit.ly/FVWebinarMN071615. The market news reports have a wealth of information; I would encourage any grower not already aware of what is available to take a look at the Market News Portal https://www.marketnews.usda.gov/mnp/fv-home even if it is not possible to attend the webinar.
