Dagger Nematode Xiphinema spp. (Cobb, 1913) Inglis, 1983 (Nematoda: Enoplea: Dorylaimia: Dorylaimina: Xiphinematinae)

Figure 9.  Schematic diagram showing detailed morphological features of a dagger nematode, Xiphinema spp.
Dagger nematodes parasitize plants. They cause economic damage and death of host crops through feeding on the roots and by spreading viral mosaic and wilting diseases, but field studies have shown that some control measures targeting reduction in the population of dagger nematodes can be effective in controlling viral diseases in susceptible crops.

Thrips in Florida Strawberry Crops

Figure 2. Thrips damage to strawberry. Credit: H. A. SmithStrawberries grown in Florida are attacked by several pests, including flower thrips. Western flower thrips and common blossom thrips (both invasive) can cause damage to strawberries in Florida; but, while the native Florida flower thrips is commonly found in strawberry blossoms, it hasn’t been established that it can cause economic damage to strawberry. This 9-page fact sheet describes thrips damage, characteristics to distinguish among the three species, and methods of control. Written by Jeff D. Cluever, Hugh A. Smith, Joe E.

The Good, the Bad, and the Ugly: What the Future Could Hold for Bs2 Tomatoes

plants inoculated with bacterial spot pathogen in spring 2012 trial Bs2 tomatoes are transgenic tomatoes that have been engineered to contain the Bs2 gene from pepper. As such, they are considered a genetically modified (GM) food, or a genetically modified organism (GMO). Numerous trials conducted by University of Florida researchers have shown the benefits of these cultivars for bacterial spot disease management, and growers and industry members recognize the potential for Bs2 tomatoes to make Florida tomato production more sustainable. This 4-page fact sheet discusses the benefits that might be realized by the adoption of Bs2 tomato varieties, and the challenges standing in the way of their commercial production. Written by S. F. Hutton, J. W. Scott, J. B. Jones, R. E. Stall, G. E. Vallad, B. J. Staskawicz, and D. M. Horvath , and published by the UF Department of Horticultural Sciences, April 2015.

Pest management of peppers in Miami-Dade County is challenging because of a climate favorable to pests. To assist local pepper growers in maintaining crop productivity and improving the quality of produce, this publication illustrates common pests including major diseases and insects and recommends Integrated Pest Management (IPM) techniques, including host resistance, cultivation, sanitation, and physical, mechanical, biological, and chemical approaches, for effective pest management.

Effects of Harvest Method on Microclimate in Florida Sugarcane

2006 Annual Research Report---Immokalee, Florida, sugarcane, crops, fields, grass. UF/IFAS Photo: Josh Wickham.The production systems for sugarcane include either green cane or burnt cane harvesting operations. Sugarcane in Florida is typically harvested with burnt cane mechanical harvesting, but there is a growing interest to better understand the effects of green cane harvest residue “trash blankets” on microclimate conditions for sugarcane growing on both organic and mineral soils of Florida, so the authors conducted a three-year study to determine the effects of each harvest method on microclimate within the surface soil profile and at a 10 cm height from the soil surface. Results are presented in this 4-page fact sheet written by Hardev Sandhu, Maninder Singh, Robert Gilbert, Kelly Morgan, Ronald Rice, Leslie Baucum, James Shine Jr., and Mike Irey, and published by the UF Department of Agronomy, April 2015.

Sting Nematode Belonolaimus longicaudatus Rau (Nematoda: Tylenchida: Belonolaimidae)

Figure 1. Sting nematode Belonolaimus longicaudatus. Credit: W. T. Crow, University of FloridaAmong the most destructive plant-parasitic nematodes to a wide range of plants, Belonolaimus longicaudatus damages plant roots. When the plants cannot take up water and nutrients from the soil, they become stunted, wilt, and with severe infestation, die. Florida is considered to be the point-of-origin for Belonolaimus longicaudatus and therefore this nematode exhibits a great deal of diversity in morphology, host preference, and genetics in our region.

Daane, University of CaliforniaAnagyrus pseudococci is an economically important biological control agent commonly used against the vine mealybug (which infests wine grapes) and the citrus mealybug. It is a solitary, internal parasitoid and lays one egg per host, with the larva developing inside the host’s body. The wasps may be commercially reared and distributed inside mummies, and they will emerge within 1-5 days after delivery. Application involves placing a bottle containing the mummies in a dry spot of the crop and allowing the adults to emerge. This 5-page fact sheet was written by Theresa Chormanski and Ronald D.

Pepper Production in Miami-Dade County, Florida

Figure 12. Bhut Jolokia pepper. Credit: Qingren WangPepper is an important vegetable crop in Miami-Dade County. Unlike other vegetable crops, peppers are relatively more adaptable to the environment, especially the heat, and are relatively easier to grow. But to be successful, careful attention must be paid to maintain healthy plants and high productivity with efficient management of soil and water for the particular needs of each variety or cultivar. This 7-page fact sheet provides general information and guidelines for pepper growers in Miami-Dade County, including major pepper varieties, and their horticultural traits, and fundamental soil and water management requirements.

Biochar Effects on Weed Management

Biochar incorporation in an agriculture field commonly used for row-crop production (e.g. corn, cotton, peanut, soybean).Biochar can potentially provide better conditions in the soil to increase plant growth. However, research has shown that weed species show minimal changes in germination and emergence patterns with the addition of biochar. Regardless, if biochar is used in the field it is important to monitor for changes in weed populations. This is especially important because biochar can decrease herbicide efficacy.

Sugarcane Mosaic

Figure 1. Leaves showing contrasting shades of green characteristic of sugarcane mosaic Credit: Philippe Rott, UF/IFASMosaic’s most distinctive symptom is a pattern of contrasting shades of green, often islands of normal green on a background of paler green or yellowish chlorotic areas on the leaf blade. It had not been a problem in Florida until 1996, when it was observed on CP72-2086, a major commercial cultivar, near the intersection of Hatton Highway and US 98. Presently, because of the limited acreage of CP72-2086, the disease is only a potential threat. This 3-page fact sheet was written by P. Rott, J. C. Comstock, R. A. Gilbert, and H. S.

Yellowmargined Leaf Beetle: A Pest of Cole Crops

igure 1. A young mustard plant being eaten by YMLB adults and larvae.The yellowmargined leaf beetle is a pest of cole or cruciferous crops that is native to South America. Since first reported in Mobile, Alabama, in 1947, the beetle has spread throughout the Gulf Coast from Texas to Florida and up into Georgia and North Carolina. It has also been reported from Illinois and California. Not considered a major pest in conventionally grown cruciferous crops because it is susceptible to a wide range of insecticides, it poses a significant threat to the growing organic industry in the southeastern United States. It is a particular problem on Asian greens such as mizuna, mibuna, and napa cabbage, as well as on other high-value cruciferous crops like turnip, mustard, and watercress.

Nutrient Management of Vegetable and Agronomic Row Crops Handbook

Florida vegetables and row cropsThrough the implementation of a series of targeted cultural practices discussed in this production guide, growers should be able to reconcile economic profitability and responsible use of water and fertilizer. Topics include: proper sampling practices and test interpretations; irrigation management methods and automation; use of alternate fertilizer materials to retain nutrients in the soil but allow adequate supply for crop uptake. Use of these BMPs ensures that adequate fertilizer rates may be achieved by combinations of UF/IFAS recommended base rates and supplemental fertilizer applications.
