Management of Powdery Mildew in Beans

Figure 6. Development of powdery mildew on pole bean plants without full sunlight. Credit: Qingren WangPowdery mildew is one of the most commonly occurring diseases on many types of beans. Although the causal organism rarely causes extensive damage, significant yield losses were reported in Columbia County when infection occurred in dry beans prior to flowering. Accurately identifying this disease and immediately taking action for control are critical to effectively prevent spread of powdery mildew in order to reduce significant losses of yield and quality. This 4-page fact sheet was written by Qingren Wang, Shouan Zhang, and Teresa Olczyk, and published by the UF Department of Plant Pathology, June 2014.

Bagrada Bug, Painted Bug, Bagrada Hilaris (Burmeister) (Insecta: Hemiptera: Pentatomidae)

Figure 1.  Dorsal view of Bagrada hilaris; adult female (left), and adult male (right).The bagrada bug is a pest of concern to Florida agriculture, and there are several similar species with which it may be confused. Bagrada bugs have been detected on plant material in trucks traveling across state borders. Twelve interceptions have been made from 2011-2013 at the FDACS agricultural inspection stations along the interstate at the Florida border. Due to the number of recent interceptions, and the ability of this pest to feed on many plants, the bagrada bug has potential to establish in Florida. Therefore, monitoring, surveillance, and educational efforts have begun in Florida to facilitate early detection and rapid response as the spread of the bagrada bug continues to other areas.

The ability to measure performance is a key component in all beef cow operations, and measuring production efficiency is becoming increasingly important. Regardless of size, producers must be able to identify the current status of their operation in order to make adjustments toward improvement. Identifying and culling the cows within the herd that are less efficient at producing a weaned calf in the environment and management system used on the ranch can be a powerful tool to improve the herd.

Facts about Quinoa

Figure 1.  Quinoa is a nutritious seed that serves as a whole grain.The U.S. Department of Agriculture?s MyPlate nutrition guide recommends that Americans consume half of their grains from whole grain foods. Whole wheat bread and oatmeal are whole grain foods that are familiar to most Americans, but lots of other whole grain foods are also available. An example of an unfamiliar whole grain food is quinoa (pronounced keen-wa). Quinoa is a nutritious seed that is simple to prepare. It can be served as a hot cereal or side dish, as a cold salad similar to pasta salad, or it can be used in recipes in place of rice or other grains. It also has the advantage of being gluten free, which is a must for people diagnosed with celiac disease. Follow the link to learn more about quinoa and what it has to offer.

Biology and Management of Common Purslane in Fruiting Vegetables, Cucurbits, and Strawberries

Figure 1.  Common purslane growth in a fallow field. Note fleshy stems and leaves with no hairs. Credit: Nathan BoydPurslane occurs throughout the year in Florida. It produces thousands of seeds per plant, which germinate readily, but can also persist in the soil for up to 15 years. Vegetative shoot fragments can survive on the soil surface for extended periods of time, then re-root when exposed to moisture and can even flower and produce seeds after they have been pulled from the soil. This characteristic enables purslane to persist and spread following cultivation. This 4-page fact sheet was written by Nathan S. Boyd, Andrew W. MacRae, Rick Kelly, and Ixchel M. Hernandez, and published by the UF Department of Horticultural Sciences, July 2014.

Dealing with Food Allergies

boy unhappy with milkA food allergy is an immune system reaction that happens after a person consumes what is normally considered a safe food. Food allergies occur more often in children than in adults: 4%?8% of those aged 4 or under and about 2% of adults are affected. Allergic reactions from food have led to over 20,000 emergency room visits per year. Annually, between 150 and 200 fatalities associated with food allergic reactions occur in the United States. This 4-page fact sheet was written by Keith R. Schneider, Renée Goodrich Schneider, Soohyoun Ahn, and Susie Richardson, and published by the UF Department of Food Science and Human Nutrition, January 2014.

BMP-Recommended Water and Phosphorus Inputs for Tomato and Watermelon Can Reduce Environmental Losses of Phosphorus and Save Water

Figure 1. Tomato and watermelon grown/harvested during the irrigation and nutrient BMP study.A BMP study was conducted at the research farm of the UF/IFAS Southwest Florida Research and Education Center in Immokalee, FL. The study evaluated two production systems made up of two levels of water and fertilizer inputs for tomato and watermelon production with seepage irrigation. The average water and P fertilizer rates used by growers in south Florida were contrasted with the recommended BMP rates. Applying BMP-recommended water and phosphorus (P) inputs for seepage-irrigated tomato and watermelon in Florida can reduce water use and P leaching to groundwater without adversely impacting fruit yield. However, given the adverse impacts on watermelon yield due to lower than sufficient levels of K, further research is needed to evaluate the fertilizer recommendations for watermelon, especially K2O rates, to ensure economic viability of farms. Our results showed that adoption of BMP-recommended P rates as a BMP did not reduce crop yield and improved water quality. This 4-page fact sheet was written by Sanjay Shukla, Gregory S. Hendricks, Thomas A. Obreza, and Willie G. Harris, and published by the UF Department of Agricultural and Biological Engineering, June 2014.

An Introduction to Annuities

Retirement aheadAn annuity contract is purchased from a life insurance company. The individual gives the insurance company a lump-sum payment or a series of payments. In return, the company will provide a stream of payments to the individual. Although an annuity is purchased from a life insurance company, it serves a different purpose than life insurance. Below is a chart comparing life insurance to annuities.

Figure 1. Harmonia axyridis beetle, a beneficial insect Credit: Lyle Buss, UF/IFASThis publication describes “natural” pesticides: alternatives that are usually less toxic to non-target organisms and the environment and that, when used correctly, can be effective substitutes for synthetic products. In this publication, natural substances used for pest management in landscapes and gardens are grouped into oils, plant extracts, insecticidal soaps, mineral insecticides, microbial insecticides, and products that control diseases. Certain products contain combinations of these groups (e.g., soap and oil). This 8-page fact sheet was written by Eileen A. Buss and Sydney G.

Water Withdrawals and Their Use in Florida in 2010

boy drinking water from hoseThis publication is based on Florida water use information collected by the United States Geological Service. It expands on EDIS document FE797 that examined Florida water withdrawals data for 2005. In addition, in EDIS document FE757 (Florida’s Water Resources), the authors describe Florida’s abundant water resources?the state receives about 54 inches of rainfall per annum, compared to 30 inches nationwide, and it overlies prolific aquifers. Whether water is scarce or abundant, however, depends not only upon available supplies, but also upon patterns of water use. To gather this information, the United States Geological Survey employs several water-use categories to develop estimates of water withdrawals and water use. This 5-page fact sheet was written by Tatiana Borisova and Jenna Rogers, and published by the UF Department of Food and Resource Economics, May 2014.

Soil pH Management for Optimum Commercial Fruit Production in Florida

Figure 2. A schematic diagram of soil pH adjustment with lime, sulfur, and nitrogen fertilizers. Liming, sulfuring, and fertilizing can all adjust soil pH. Liming increases the plow layer pH; sulfuring may decrease the plow layer pH. Nitrate nitrogen increases root zone pH; ammonium nitrogen reduces root zone pH.Soil pH is one of the most important soil chemical properties and affects nutrient bioavailability and microbial activity. The purpose of this article is to provide an overview for faculty, crop consultants, crop advisors, fruit growers, and students who are interested in fruit production. The crop response to soil pH varies due to crop genetic diversity. Soil pH determines nutrient bioavailability and hence fruit growth, yield, and quality.

Socio-Demographic Characteristics and Concerns about Water Quality Issues of Master Gardener Program Volunteers

Florida Master Gardeners working with childrenTo respond to residents’ informational needs, the Cooperative Extension Service offers a variety of volunteer training and certification programs. Who participates in such programs? What types of audiences are being reached? Do such programs increase knowledge and change behavior of the volunteers? In this article, we attempt to answer these questions by summarizing existing studies and using responses to a regional public survey, and by focusing on the Master Gardener program and surface water quality issues as examples. This 7-page fact sheet was written by Tatiana Borisova, Michael Smolen, Maria Pilar Useche, Jon Calabria, Nickola Sochacka, Damian Adams, Diane Boellstorff, Jason Evans, and Robert Mahler, and published by the UF Department of Food and Resource Economics, May 2014.

Mole Cricket IPM Guide for Florida

Figure 1.  Pest mole cricket management: observe damage, collect samples, identify specimens, establish a damage threshold, select management options, and develop a long-term IPM program.Mole crickets can become serious pests of turfgrasses, pastures, and vegetable seedlings. The first step in determining if you have a mole cricket problem at a site is to compare the existing damage to pictures of known mole cricket damage. If the damage is likely caused by mole crickets, specimens should be obtained and the pest identified. You then should determine if the number of mole crickets is great enough to cause an unacceptable level of damage and decide what control measures should be used. Eventually, a long-term, sustainable integrated pest management (IPM) program should be established. This 20-page guide will help you identify mole cricket infestations and manage them effectively and economically while minimizing environmental impacts. Written by C. R. Kerr, N. C. Leppla, E. A. Buss, and J. H. Frank, and published by the UF Department of Entomology and Nematology, May 2014.
