U.S. Secretary of Agriculture Sonny Perdue announced an initial list of additional commodities that have been added to the Coronavirus Food Assistance Program (CFAP), and that the U.S. Department of Agriculture (USDA) made other adjustments to the program based on comments received from agricultural producers and organizations and review of market data. Producers will be able to submit applications that include these commodities on Monday, July 13, 2020. USDA’s Farm Service Agency (FSA) is accepting through Aug. 28, 2020, applications for CFAP, which helps offset price declines and additional marketing costs because of the coronavirus pandemic. USDA expects additional eligible commodities to be announced in the coming weeks. USDA collected comments and supporting data for consideration of additional commodities through June 22, 2020. Changes to CFAP include: Adding the following commodities: alfalfa sprouts, anise, arugula, basil, bean sprouts, beets, blackberries, Brussels sprouts, celeriac (celery root), chives, cilantro, coconuts, collard greens,[Read More…]

When ground level ozone is high enough to trigger an Air Quality Action Day alert from the Indiana Dept. of Environmental Management (IDEM) it is a reminder that crops may be injured by ozone. A number of areas around the state have experienced alerts in recent days, e.g. July 14 in S. Indiana. If crops show the symptoms described below and ozone levels have been high, consider the possibility of ozone injury. Ozone is a gas with three oxygen atoms per molecule. It is formed in the air when nitrogen oxides and volatile organic compounds react in the presence of sunlight. Ground-level ozone is a primary component of smog. Ozone harms people by aggravating existing breathing problems like asthma and injuring lung tissue. It harms sensitive plants by damaging leaf tissue, reducing the capacity to photosynthesize. IDEM issues daily air quality forecasts for ground level ozone from May to September,[Read More…]

Hail injury on pumpkin

(This article is modified from one published in issue 537 of this newsletter written by Sarah E. Hulick and Steve Reiners, Department of Horticulture Science, Cornell University, NYSAES. Liz Maynard also contributed to this article.) Recent storms have brought hail to parts of Indiana. Loss of yield and quality in vegetable crops due to hail depends on the crop, stage of growth, amount of injury, and future growing conditions. Disease control is absolutely essential after hail damage. Surviving plants will also benefit from a sidedressing of nitrogen about a week after the damage occurred. The following is a summary of all the information we could find relating to hail and vegetable recovery. Bell Peppers. A study was conducted in North Carolina to determine the impact of hail on the incidence of bacterial spot. The hailstorm occurred 38 days after transplanting when the plants were still young and recovery was possible.[Read More…]

While we might be struggling with the heat and lack of rain, there is one pest that is loving it, Mites! Now is the time to be on your toes watching out for this pest. Early detection and treatment are key. In protected environments prevention and early intervention are especially important; In the field, heavy rains can help knock these pests back. Two-spotted spider mites (TSSM) are one of the most common mite pests on vegetables. TSSM occur throughout the world. They are known to feed on over 300 plant species, including tomatoes, cucumbers, melons, grapes, apples, and a variety of common flower and weed species. They disperse by walking or flying on the wind currents. The adults are a pale green to yellowish color, or almost appear translucent, with two black spots on their back. Eggs and nymphs are present and overlapping with adults. The eggs are very small[Read More…]

Scientific names: Erigeron canadensis or Conyza canadensis Horseweed, also known as marestail, fleabane, or colt’s tail, is a common and troublesome weed throughout North America due to its high seed production, wind dissemination, lack of seed dormancy, and adaptability to dry and moist soil. Moreover, horseweed populations have shown to be resistant to Group 2 (ALS-inhibitors) and Group 9 (glyphosate) herbicides. Historically, horseweed has had many uses. Native Americans in the Zuni River Valley of New Mexico inserted crushed horseweed flowers into their nostrils to stimulate sneezing and help relieve rhinitis. Other Native Americans used the leaves to treat sore throat and dysentery. Dried plants were scattered in animal bedding to prevent fleas. Young leaves were used as a flavoring substitute for tarragon. Identification: Seedling is a basal rosette. Cotyledons are oval, and young basal leaves are egg-shaped with toothed margins. After the stem elongates, basal leaves deteriorate. Stem leaves[Read More…]

The past 30 days have been met with warmer than normal temperatures in the northern counties and drier than normal conditions throughout most of the state (Figures 1 and 2). This warm and dry environment is conducive to developing drought – particularly with the increased evapotranspiration rates. While climate outlooks are calling for increased confidence of above-normal precipitation throughout the rest of July, these events are likely to remain spotty with inconsistent coverage across the state. For planning purposes, it may be helpful to know what the forecast is for reference evapotranspiration (ET0). The National Weather Service provides a nice graphical tool (https://digital.weather.gov/) where users can zoom into their area of interest and then view a variety of variables for future time periods out to six days (e.g., Figure 3). Several derivations of the forecasts of reference evapotranspiration (FRET) can be found at the very bottom of the variable pull-down[Read More…]

The roller coaster ride of Indiana weather continues. Things were drying out across the state with signs of browning lawns, rolling vegetation leaves, and lowering pond and stream levels. Then the rains came. Most of the state received between 2 and 3 inches of precipitation from June 20 through 29th – with wetter areas to the south and drier areas to the northeast. While this may seem good enough to relieve any concerns about drought developing, the temperatures have been high to encourage the evaporation of those wet surfaces. As a result, the US Drought Monitor has kept most of the state at “Abnormally Dry”. The climate outlook for July 8-14 shows increased confidence of below-normal precipitation with the possibility of this dryness continuing into mid-July. Additionally, probabilities are significant that temperatures will be above normal – further exacerbating any dryness due to lack of rainfall. The climate outlook for[Read More…]
