Book excerpt: In the period from 1977 to 1980 a number of field experiments were carried out at the University of Florida Agricultural Research and Education Center in Homestead to determine the effect of various levels of discrete or repeated, mechanical defoliation of 'Walter 1 tomato plants on components of marketable yield. Treatments consisted of 100% defoliation and separate 20%, 40%, 60%, and 80% defoliations of the lower or the upper part of the plants. A differential sensitivity to defoliation in the course of the plants' development was observed. The most sensitive times appeared to be early in the season and at mid-season. In most cases, however, at least 60% of the foliage had to be removed before total marketable fruit yields and yields in the largest, most profitable size categories were significantly reduced when compared to yields from the control plants. Tomato plants exhibited less tolerance of repeated defoliation with removal of 40% of the total leaf area often resulting in yield loss in the first harvest. However, the total yield of the first two harvests combined was not significantly reduced when compared to yields from nondefoliated plants. The total marketable yield of the tomato plants at any level of defoliation was significantly correlated with the gross revenue a grower would obtain from the harvested fruit based on different prices for the various size categories. Major defoliation associated with leafminer damage in commercial production plantings is the result of the adverse effect of pathogens inhabiting the leaf mines. In this study the pathogen most commonly associated with the leaf mines has been identified as Alternaria alternata (Fries) Keissler. It appears to be only weakly parasitic, its detrimental effect depending on the nutrient supply provided in the mine by mesophyll cells lacerated by the leafminer larvae. Additional damage to the leaf can also be done by other pathogens such as J

Book Synopsis Environmental, Cultural and Insecticidal Effects on the Vegetable Leafminer, Liriomyza Sativae Blanchard, and Its Parasites by : Earl Haven Tryon
Download or read book Environmental, Cultural and Insecticidal Effects on the Vegetable Leafminer, Liriomyza Sativae Blanchard, and Its Parasites written by Earl Haven Tryon and published by . This book was released on 1979 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vegetable leafminer, Liriomyza sativae Blanchard (Diptera: Agromyzidae), has been a serious pest of Florida's tomato and celery industry since 19 72. Leafminer populations were studied on commercial vegetable farms in two areas of Florida. Initial research focused on celery and tomato transplant seedlings grown in plant production ranges in Sun City, Florida, during the fall and winter of 1977 and 1978 (October to March) . In the spring and summer of 1978 (March to July) the research was conducted on commercial celery farms in Belle Glade, Florida, and complementary laboratory experiments were conducted in Gainesville, Florida. Adult leafminer invasion of the transplant production farm, monitored with yellow cardboard traps covered by sticky, transparent plastic, was the result of prevailing winds over nearby tomato fields. Ratio of larval mines to stipples was related to adult leafminer preference for host seedlings. Leafminer host preference was influenced by prior host developmental association, by host cultivar and species and seedling age. The number of adult leafminers and parasites reared from celery leaf samples was influenced by temperature, humidity and the number of leaves per container. The effect of temperature (15.6°, 18.2°, 21.1°, 22.2°, 23.9°, 26.7°, 29.4° and 32.2°C) on pupal development was linear. A degree-day value for pupal development, calculated from 6 constant temperatures, was 127.8 (degree-day C) for the leafminer and 141.2 (degree-day C) for the leafminer parasite, Opius spp. Experimental field plots and seedlings in flats had extremely high levels of parasitism (>90%). The major parasites were Chrysonotomyia formosa (Westwood), Diglyphus intermedins (Girault) and Opius spp. No interactions or interdependence among parasite species could be demonstrated. Permethrin (0.20 lb. A.I. /A.), methamidophos (1.00 lb. A.I. /A.), fenvalerate (0.40 lb. A.I. /A.) and permethrin (0.10 lb. A.I. /A.) + oxamyl (0.25 lb. A.I. /A.) were the most effective insecticides significantly (P=0.05) reducing the number of mines on celery and tomato and celery seedlings. Methamidophos was the only insecticide effective in significantly (P=0.05) reducing the number of adult parasites reared from both celery and tomato leaf samples.

Download or read book Sustainable Management of Arthropod Pests of Tomato written by Waqas Wakil and published by Academic Press. This book was released on 2017-11-19 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Management of Arthropod Pests of Tomato provides insight into the proper and appropriate application of pesticides and the integration of alternative pest management methods. The basis of good crop management decisions is a better understanding of the crop ecosystem, including the pests, their natural enemies, and the crop itself. This book provides a global overview of the biology and management of key arthropod pests of tomatoes, including arthropod-vectored diseases. It includes information that places tomatoes in terms of global food production and food security, with each pest chapter including the predators and parasitoids that have specifically been found to have the greatest impact on reducing that particular pest. In-depth coverage of the development of resistance in tomato plants and the biotic and abiotic elicitors of resistance and detailed information about the sustainable management of tomato pests is also presented. Provides basic biological and management information for arthropod pests of tomato from a global perspective, encompassing all production types (field, protected, organic) Includes chapters on integrated management of tomato pests and specific aspects of tomato pest management, including within protected structures and in organic production Presents management systems that have been tested in the real-world by the authors of each chapter Fully illustrated throughout with line drawings and color plates that illustrate key pest and beneficial arthropods associated with tomato production around the world

This book was released on 2006-04-11 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Centre for Advanced Mediterranean Agronomic Studies (CIHEAM), established in 1962, is an intergovernmental organization of 13 countries: Albania, Algeria, Egypt, France, Greece, Italy, Lebanon, Malta, Morocco, Portugal, Spain, Tunisia and Turkey. Four institutes (Bari, Italy; Chania, Greece; Montpellier, France; and Zaragoza, Spain) provide postgraduate education at the Master of Science level. CIHEAM promotes research networks on Mediterranean agricultural priorities, supports the organization of specialized education in member countries, holds seminars and workshops bringing together technologists and scientists involved in Mediterranean agriculture and regularly produces diverse publications including the series Options Méditerranéennes. Through these activities, CIHEAM promotes North/South dialogue and international co-operation for agricultural development in the Mediterranean region. Over the past decade, the Mediterranean Agronomic Institute of Zaragoza has developed a number of training and research-supporting activities in the field of agroecology and sustainability of agricultural production systems. Some of these activities have been concerned with the rational use of pesticides and more particularly with the implementation of integrated control systems in order to gain in efficacy and decrease both the environmental impact and the negative repercussions for the commercialization of agricultural products.
